For the final couple of years, all eyes have been on LG Show (LGD) in hopes of them producing a aggressive OLED provide chain that would rein in Samsung Show’s monopoly over the cellular OLED market. We first acquired wind of this potential upbringing early-2017 when Google provided to take a position almost $1 billion USD into LG Show in hopes to safe a secure provide of versatile OLED for what can be the Pixel 2 XL. A couple of months later, the entire ordeal appeared to turn out to be an order of magnitude extra critical when Apple hopped on board and reportedly invested $2.7 billion USD into the South Korean show maker in trade for placing up a brand new OLED manufacturing line solely for Apple. Fall got here round and we acquired to see an early preview of what was to return with LG Show’s first cellular OLED on a shopper smartphone on the LG V30 and the Pixel 2 XL. Early receptions to the panels have been overwhelmingly damaging (which I’ve beforehand coated in depth), tipping many to consider that LGD was not the OLED savior we have been hoping for, and even angering many shoppers to the purpose the place they might bash OEMs for even contemplating sourcing their shows from LGD.
Half a yr later, LG Show signed on as Apple’s second OLED provider, and shortly after, handed a collection of Apple’s stringent high quality exams. Thus, LG Show re-piqued our consideration, and we seemed ahead to the discharge of the LG V40 ThinQ and the Google Pixel three as each have been rumored to make use of LGD’s next-generation cellular OLED. The Pixel three’s show was confirmed to be sourced from LGD, and we have now reviewed it to be an general noticeable enchancment over each the Pixel 2 (a Samsung show) and particularly the Pixel 2 XL of final yr. Nevertheless, the Pixel three’s LGD panel nonetheless had a few of the points we famous from the Pixel 2 XL, however to a lesser extent. Whereas nonetheless an honest panel and a transparent enchancment, the Pixel three’s show nonetheless wasn’t fairly the Samsung-catcher we have been hoping for.
It’s not fairly the top of the street for this era, nevertheless. We nonetheless need to take an excellent take a look at LG’s newest flagship, the LG V40 ThinQ.

Efficiency Abstract
The LG V40 ThinQ sports activities a versatile OLED on the entrance that rounds off the bezels in the direction of the edges. The rounding begins simply on the fringe of the seen display, making it a troublesome candidate for well-fitting display protectors. The 3D entrance glass can also be wrongdoer to the handset’s hollow-feeling entrance, which was additionally noticed with the Pixel 2 XL’s 3D glass.
The display’s native decision helps as much as 3120×1440 pixels, however the show is about to 2340×1080 by default. At this decision, it’s noticeably much less crisp than in its native decision, particularly when viewing textual content. At its native decision, the display’s pixels are unresolvable previous 9.1 inches, which ought to seem a lot sharp for typical smartphone viewing distances (~12 inches) with 20/20 imaginative and prescient, with slight room to spare to accommodate these with larger visible acuity.
In show brightness, the LG V40 ThinQ’s show is similar to the likes of Apple and Samsung shows in its Auto mode underneath excessive ambient mild, measuring a most white degree of 556 nits at 100% APL, 781 nits at 50% APL, and peaking at 914 nits when emitting a tiny white area of the display at 1% APL.
Out of the field the LG V40 ThinQ targets a cool and punchy colour profile that’s about 25% extra saturated than our normal RGB shade area. Within the Auto and Skilled profiles, it’s attainable to switch the show’s general colour temperature (albeit in a flawed method) and to switch the relative reds, greens, and/or blues. The handset provides 6 different colour profiles, and do present profiles that accommodate the P3, Adobe RGB, and the sRGB colour areas. Nevertheless, all three of the reference colour profiles have a greenish-white level, and solely the Net profile (which targets the sRGB colour area) competently matches its goal (although as seen in our Pixel three show evaluation, LGD’s panels are utterly able to having near-perfect colour accuracy with more proficient calibration). Moreover, not one of the colour profiles help Android’s colour administration, launched in Android eight.zero Oreo, and even when it did, it wouldn’t imply a lot since virtually no Android apps help it.
Shade tones are shaded adequately on common. Shadows might seem barely lighter than commonplace, and mid-tones seem barely too darkish, with a mean ensuing gamma of two.25 for the calibrated shade profiles and about 2.three for the vast non-standard profiles, together with Auto.
In show energy, we measured the LG V40 ThinQ show to emit with 25% extra luminous depth per watt than the LG show on the Pixel three at 100% APL, and eight% extra at 50% APL. The facility efficacy figures for the LG V40 show are greater than most different OLED shows, however it isn’t more likely to make a big distinction in handset battery life.

Methodology ▼
To acquire quantitative shade knowledge from the show, we stage device-specific enter check patterns to the handset and measure the show’s ensuing emission utilizing an i1Pro 2 spectrophotometer. The check patterns and gadget settings we use are corrected for numerous show traits and potential software program implementations that may alter our desired measurements. Many different websites’ show analyses don’t correctly account for them and consequently their knowledge could also be inaccurate.
We first measure the show’s full grayscale and report the perceptual colour error of white, together with its correlated shade temperature. From the readings, we additionally derive the show gamma utilizing a least-squares match on the theoretical gamma values of every step. This gamma worth is extra significant and true-to-experience than people who report the gamma studying from show calibration software program like CalMan, which averages the theoretical gamma of every step as an alternative.
The colours that we goal for our check patterns are impressed by DisplayMate’s absolute shade accuracy plots. The colour targets are spaced roughly even all through the CIE 1976 chromaticity scale, which makes them wonderful targets to evaluate the entire shade copy capabilities of a show.
The grayscale and shade accuracy readings are taken in increments of 20% over the show’s perceptual (non-linear) brightness vary and averaged to realize a single studying that’s correct to the general look of the show. One other particular person studying is taken at our reference 200 cd/m² which is an effective white degree for typical workplace circumstances and indoor lighting.
We primarily use the colour distinction measurement CIEDE2000 (shortened to ΔE) as a metric for chromatic accuracy. ΔE is the business normal shade distinction metric proposed by the Worldwide Fee on Illumination (CIE) that greatest describes uniform variations between colours. Different colour distinction metrics exist as nicely, corresponding to the colour distinction Δu′v′ on the CIE 1976 chromaticity scale, however such metrics have been discovered to be inferior in perceptual uniformity when assessing for visible noticeability, as the edge for visible noticeability between measured colours and goal colours can range wildly between shade distinction metrics. For instance, a colour distinction Δu′v′ of zero.zero10 shouldn’t be visually noticeable for blue, however the identical measured colour distinction for yellow is noticeable at a look. Notice that ΔE shouldn’t be good itself, nevertheless it has come to be probably the most empirically-accurate colour distinction metric that presently exists.
ΔE usually considers luminance error in its computation, since luminance is a needed element to utterly describe colour. Nevertheless, because the human visible system interprets chromaticity and luminance individually, we maintain our exams patterns at a continuing luminance and compensate the luminance error out of our ΔE values. Moreover, it’s useful to separate the 2 errors when assessing a show’s efficiency as a result of, identical to our visible system, it pertains to totally different points with the show. This manner we will extra completely analyze and perceive the efficiency of a show.
When the measured shade distinction ΔE is above three.zero, the colour distinction might be visually observed at a look. When the measured colour distinction ΔE is between 1.zero and a couple of.three, the distinction in shade can solely be observed in diagnostic circumstances (e.g. when the measured colour and goal shade seem proper subsequent to the opposite on the show being measured), in any other case, the colour distinction is just not visually noticeable and seems correct. A measured colour distinction ΔE of 1.zero or much less is claimed to be utterly imperceptible, and the measured colour seems indistinguishable from the goal colour even when adjoining to it.
Show energy consumption is measured by the slope of the linear regression between the handset battery drain and show luminance. Battery drain is noticed and averaged over three minutes at 20% steps of brightness and trialed a number of occasions whereas minimizing exterior sources of battery drain.
Brightness
Our show brightness comparability charts examine the utmost show brightness of the LG V40 ThinQ relative to different shows that we have now measured. The labels on the horizontal axis on the underside of the chart symbolize the multipliers for the distinction in perceived brightness relative to the LG V40 ThinQ show, which is fastened at “1×”. The magnitude of the shows’ brightnesses, measured in candelas per sq. meter, or nits, are logarithmically scaled based on Steven’s Energy Regulation utilizing the modality exponent for the perceived brightness of some extent supply, scaled proportionally to the brightness of the LG V40 ThinQ show. That is achieved as a result of the human eye has a logarithmic response to perceived brightness. Different charts that current brightness values on a linear scale don’t correctly characterize the distinction in perceived brightness of the shows.
When measuring the show efficiency of an OLED panel, it is very important perceive how its know-how differs from conventional LCD panels. LCDs require a backlight to cross mild via shade filters that block wavelengths of sunshine to supply the colours that we see. An OLED panel is able to having every of its particular person subpixels emit their very own mild. Which means the OLED panel should share a specific amount of energy to each lit pixel from its most allotment. Thus, the extra subpixels that have to be lit up, the extra that the panel’s energy must be divided over the lit subpixels, and the much less energy that every subpixel receives.
The APL (common pixel degree) of a picture is the typical proportion of every pixels’ particular person RGB elements throughout the whole picture. For instance, a totally pink, inexperienced, or blue picture has an APL of 33%, since every picture consists of utterly lighting up solely one of many three subpixels. The entire shade mixtures cyan (inexperienced and blue), magenta (purple and blue), or yellow (pink and inexperienced) have an APL of 67%, and a full-white picture that utterly lights up all three subpixels has an APL of 100%. Moreover, a picture that’s half black and half white has an APL of 50%. Lastly, for OLED panels, the upper the entire on-screen content material APL, the decrease the relative brightness of every of the lit pixels. LCD panels don’t exhibit this attribute (barring native dimming), and due to it, they are typically a lot brighter at larger APLs than OLED panels.

The LG V40 ThinQ show, identical to Samsung’s, helps a better peak brightness in auto brightness, in comparison with guide, when underneath excessive ambient lighting. A fullscreen white picture at most brightness on the LG V40 ThinQ show was measured to emit 556 nits, which seems solely about 7% dimmer than Samsung’s and Apple’s 640 nits on their respective flagship shows.
Nevertheless, at 50% APL, which is a greater illustration of most content material, the LG V40 ThinQ show performs terribly properly, measuring a white degree of 781 nits. This measures larger than Apple’s newest handsets and is indistinguishable from Samsung’s peak emission at this APL. At a tiny 1% APL, the LG V40 show peaks out at 914 nits.
At its dimmest, the LG V40 ThinQ can go as little as 2.three nits, which places it across the similar minimal brightness as most Androids OLEDs. Apple’s newest OLED shows, nevertheless, measure right down to 1.eight nits, which noticeably seems a tad dimmer (by about 12%).
For the OLED’s dynamic brightness response to on-screen APL, it seems that LG has made an effort to regulate the white degree at totally different APLs (outdoors of excessive brightness mode), measuring a most luminance delta of eight% between the very best white degree and the bottom white degree between 100% and 10% APL, which is superb. That is required to have constant show gamma and colour accuracy at totally different brightnesses and APLs. Nevertheless, we discovered that LG nonetheless has a various ensuing gamma at totally different APLs even with proficient dynamic brightness management, which is a disgrace.
Black clipping, informally referred to as “black crush,” is when darker colour tones seem similar to the show’s rendering of pure black (the show’s “black degree”). We measured our LG V40 show to have a black clipping threshold for drive ranges of two.7% or decrease, which is on par with what we have now measured for the Galaxy Notice eight and the Galaxy Observe 9. The LG show on the Pixel three has a black threshold of 6.zero%, with the “larger high quality” Samsung panel on the Pixel three XL having a black threshold of Four.7%, which additional helps that the black clipping on their panels, even on the Pixel 2 XL, is because of their panel calibration (on prime of different supporting knowledge) and never because of the LG show as some have criticized. LG is doing very nicely right here.
Colour Profiles

- LG V40 ThinQ Shade Gamut
The LG V40 ThinQ supplies an awesome seven totally different shade profiles to select from, defaulting to Auto.
The default Auto shade profile is a large gamut color-stretching profile that the majority intently matches the P3 shade area. It has an deliberately colder white level at 7282Okay, with deeper blues and barely deeper greens than the P3’s primaries. LG, in a press launch, informed us that Auto can “routinely analyze present content material, corresponding to video, recreation, photograph or net, and optimize show setting whereas decreasing energy consumption,” however I couldn’t get this to occur even on pictures with embedded ICC profiles. On this profile, linear RGB changes can be found in addition to a slider to switch the colour temperature.
LG V40 ThinQ Colour Temperature RGB Stability
Sadly for LG, whoever was answerable for the colour temperature slider failed miserably in doing so, because the “Cooler” values truly decreased the correlated shade temperature of the white level, and the “Hotter” values elevated it, reverse to instinct. What LG has executed is lowered the inexperienced drive ranges and elevated the pink drive ranges because the slider approached “Hotter,” whereas barely touching the blue drive ranges. All of the changes make for very comparable correlated shade temperatures, which is a superb instance of how comparable correlated colour temperatures can look very totally different. For this reason a white level with a correlated shade temperature near 6504Okay just isn’t all the time thought-about correct, which you’ll quickly see is the case for the LG V40 ThinQ show.
The Cinema profile targets the P3 shade area, which is the colour area generally focused by the movie business. Because the profile makes an attempt to focus on a show gamma of two.2, it’s concentrating on what’s now colloquially being referred to as Show P3, in distinction to DCI-P3, which targets a show gamma of two.6. It has a white level of 6477Okay, very near its D65 goal of 6504Okay.
The Sports activities profile seems just like the Auto colour profile, besides with barely less-saturated blues and a a lot colder white level at 8297Okay. I do not know what this has to do with sports activities.
The Recreation profile is nearly equivalent to the Sports activities profile, besides with a white level that’s in-between the Auto and Sports activities profile at 7877okay. This profile additionally doesn’t make any sense.
The Photograph profile appears to aim to focus on the Adobe RGB colour area, which is often focused by shade profiles named “Photograph” (like on Samsung’s units). It matches the right purple and blue primaries, which is shared with sRGB, however it appears to undershoot the inexperienced main. It has a white level of 6478Okay, very near its D65 goal of 6504Okay.
The Net profile targets the sRGB shade area, the usual “default” colour area of the world extensive net and most content material. This would be the color-accurate profile for nearly all circumstances, apart from when the content material is described in different shade areas, which continues to be few and uncommon inside the Android ecosystem with the notable exception of HDR media on sure platforms resembling YouTube and Netflix. It has a white level of 6489Okay, very near its D65 goal of 6504Okay.
The Skilled profile by default is equivalent to the Auto profile, with linear RGB adjustment and shade temperature sliders. There’s additionally further sliders out there that may modify the Saturation, Hue, and synthetic Sharpness of the display.
Distinction and Gamma
The gamma of a show determines the general picture distinction and lightness of the colours on a display. The business commonplace gamma that’s for use on most shows follows an influence perform of two.20. Larger show gamma powers will end in greater picture distinction and darker shade mixtures, which the movie business is progressing in the direction of, however smartphones are seen in many various lighting circumstances the place larger gamma powers will not be applicable. Our gamma plot under is a log-log illustration of a shade’s lightness as seen on the LG V40 ThinQ show versus its related enter drive degree: Measured factors which are greater than the Normal 2.20 line means the colour tone seems brighter and decrease than the Commonplace 2.20 line means the colour tone seems darker. The axes are scaled logarithmically because the human eye has a logarithmic response to perceived brightness.
Most trendy flagship smartphone shows now include calibrated colour profiles which are chromatically correct. Nevertheless, as a consequence of OLED’s property of decreasing the typical lightness of the colours on the display with growing content material APL, the primary distinction within the complete shade accuracy of recent flagship OLED shows is now within the ensuing gamma of the show. The gamma of a show makes up the achromatic (grayscale element) picture, or the construction of the picture, which people are extra delicate in perceiving. Subsequently it is extremely necessary that the ensuing gamma of a show matches that of the content material’s, which usually follows the business commonplace 2.20 energy perform.

LG is utilizing a switch perform that begins sluggish (γ 2.2) earlier than almost overshooting at 90% drive degree, by which it kinks in the direction of 95% then lastly fills to 100%. This isn’t splendid, and an apparent trace at a wrestle in calibration, however higher than having an general gamma that’s too excessive or too low. What LG is doing is retaining shadows legible by beginning with a low, lighter gamma within the shadows, however it persists by means of the mid-tones and the switch perform should compensate by rushing up. Nevertheless, the tempo of the switch perform doesn’t appear to align at 100%, in order that they throw in a “repair” on the greater drive ranges. Consequently, shadows seem barely brighter than commonplace on the LG V40 ThinQ, with darker mid-tones, and highlights could also be clipped — some larger drive ranges are literally measured to be barely dimmer than drive ranges under it.
Colour Temperature
The colour temperature of a white mild supply describes how “heat” or “chilly” the sunshine seems. Colour sometimes wants at the least two factors to be described, whereas correlated shade temperature is a one-dimensional descriptor that leaves out important chromaticity info for simplicity.
The sRGB shade area targets a white level with a D65 (6504Okay) shade temperature. Concentrating on a white level with D65 colour temperature is important in shade accuracy because the white level impacts the looks of shade mixtures. Observe that, nevertheless, a white level with a correlated colour temperature that’s near 6504Okay might not essentially seem correct! There are various shade mixtures that may have the identical correlated shade temperature (referred to as iso-CCT strains) — some that don’t even seem white. Due to this, shade temperature shouldn’t be used as a metric for white level colour accuracy. As an alternative, we use it as a software to convey the tough look of the white level of a show and the way it shifts over its brightness and grayscale. Whatever the goal colour temperature of a show, ideally its correlated colour temperature of white ought to stay constant in any respect drive ranges, which would seem as a straight line in our chart under. By observing the colour temperature chart at minimal brightness we will get an concept of how the LG V40 ThinQ’s panel handles low drive ranges earlier than probably clipping blacks.

Within the LG V40’s large color-stretching profiles, the white level consistency seems principally wonderful. There does appear to be a pointy shift, nevertheless, in cooler temperatures at 10% drive ranges and under, which can make darkish backgrounds seem a unique temperature with growing severity at decrease brightnesses. The identical shall be true for the calibrated shade profiles, which seem extra jagged all through your complete curve with a gradual shift in the direction of cooler temperatures under 50% drive ranges.
Colour Accuracy
Our colour accuracy plots present readers with a tough evaluation of the colour efficiency and calibration developments of a show. Proven under is the bottom for the colour accuracy targets, plotted on the CIE 1976 chromaticity scale, with the circles representing the goal colours.
Base Shade Accuracy Plots chart
Within the LG V40 ThinQ colour accuracy plots under, the white dots symbolize the measured colour as proven on the show plotted within the CIE chart. The related trailing shade represents the severity of the colour error: Inexperienced trails signify that the measured colour distinction could be very small and that the colour seems correct on the show, whereas yellow trails point out that the colour distinction may be observed at a look, and at even larger severity with orange and pink trails.
LG V40 ThinQ sRGB Accuracy Plots: Net Profile
Beginning on the profile with crucial shade area to focus on, the Net profile does an alright job at reproducing the sRGB colour area. Nevertheless, as proven on the colour accuracy plots above, the white level has a noticeable colour error shifting in the direction of inexperienced, which can also be observable on the plot chart within the yellow, cyan, and cyan-blue colour mixtures. Pure reds are additionally barely oversaturated, however not too-noticeably so. General, the profile has a mean shade error ΔE of 1.7 and a most shade error ΔE of three.1 at 100% cyan-blue and 25% yellow, which is usually correct and acceptable for hobbyist-level sRGB colour work in pictures and video.
LG V40 ThinQ P3 Accuracy Plots: Cinema Profile
The Cinema profile, nevertheless, isn’t as correct and incorporates much more colours with greater colour variations. Virtually all colours, apart from the gamut primaries (100% pink/blue/inexperienced), are oversaturated, and there’s noticeable error all all through the reds, red-yellows, yellows, and greens. The white level shared with the Net profile can also be too inexperienced. The profile has a mean shade distinction that’s thought-about just-noticeable (ΔE = 2.three), with a most error ΔE of Four.2 throughout the red-yellow-green area. I want to reiterate that this profile is supposed for content material that targets the P3 colour area, and on a regular basis use of it can end in content material colours that may seem oversaturated.
LG V40 ThinQ Adobe RGB Shade Accuracy Plots: Photograph Profile
The Photograph profile can also be not too good, starting with the show’s inexperienced emitter not able to reaching the complete chromaticity of the Adobe RGB inexperienced main; nevertheless, the 100% inexperienced shade distinction just isn’t noticeable. Under 100% inexperienced saturation, nevertheless, there’s noticeable colour error with a excessive colour error ΔE of 5.zero at 25% inexperienced. Yellows additionally present lots of noticeable errors, a couple of different just-noticeable colour variations are scattered all through the gamut. The profile has an general common colour error ΔE of two.1 (which is technically principally correct), however the excessive colour errors the profile incorporates makes it unsuitable for color-critical work within the Adobe RGB colour area.
Show Overview
Remaining Ideas on the LG V40 ThinQ Show
From the “worst viewing angles” on an OLED with the blue shift on the Pixel 2 XL, the LG V40 ThinQ show has the perfect viewing angles I’ve seen on a cellular show, and utterly with out the jarring purple/inexperienced striated mini-shifts as seen on many angles on even the perfect of Samsung’s shows. That is one thing I already famous that wasn’t current on the Pixel 2 XL and LG V30 show, and I made a robust prediction that, due to how LGD tackles angular shifts, they might surpass Samsung very quickly in that division, they usually have. There have been already a couple of fortunate customers (myself included) with Pixel 2 XL models that had little or no “blue shift” and have been corresponding to the next-gen LG V40. In show brightness, the LG V40 ThinQ is corresponding to the perfect of the perfect in OLED, plain and easy. In shade accuracy, LG Cellular is almost certainly accountable for the calibration, as the colour accuracy on the LGD panel on the Pixel three is phenomenal.
One of many newest enhancements Samsung has made to their OLED DDICs is their dynamic brightness management which permits calibrated show profiles to focus on a selected show gamma rather more precisely, leading to trustworthy colour tonality and even larger chromatic accuracy. That is accomplished by both limiting the voltage of the show TFTs, no matter APL/voltage load, to its capability at 100% APL TFT voltage load, or growing the utilized voltage at greater APLs. Because the peak brightness of Samsung’s shows at 100% APL haven’t elevated, it appears they’ve utilized the previous. This was a facet I didn’t anticipate LG Show to implement so quickly, however it’s evident that they’ve within the LG V40 by their peak brightness readings at totally different APLs. Samsung didn’t implement this till the Galaxy S9, and the Samsung panel and DDIC within the Pixel three XL use the identical tech. Nevertheless, this was not evident within the Pixel three’s LGD-made OLED, so it isn’t but recognized whether it is LGD’s proprietary DDIC tech or if they’ll ship it out with their panel package deal.
Regardless of the seemingly excessive variety of “Bads” listed for its show, the LG V40 ThinQ nonetheless receives an A- grade because the Bads are very nitpicky and are usually not an enormous detriment to the general enjoyment of wanting on the LG V40’s show. As an alternative, enchancment in a few of these final, hard-to-perfect traits is what is required to really obtain an A+ and even an S grade, separating the great from one of the best of one of the best — which, for now, are reserved to the iPhone X-series shows.
LG has garnered a variety of animosity all through the previous couple of years, particularly of their handsets. Their cellular show division’s preliminary vital OLED look on the LG V30 and the Pixel 2 XL reaped LG a fair worse popularity. Month after month the general public continued to ignore and condescend their cellular OLED efforts regardless of the numerous investments from Google and Apple, with mockeries like “LG’s shows are at the very least 5 generations behind,” and that “they’ll by no means be capable of catch as much as Samsung.”
Nicely, it seems to be like they have already got.
