The OLED affectation on the Samsung Galaxy Note 3 is the best-performing adaptable OLED affectation to date in every way. But its a lot of absorbing achievement? It's the brightest adaptable affectation we've anytime tested.
The Samsung Galaxy Note and Galaxy S Smartphones are flagship online writing for Samsung to appearance off its latest and greatest OLED affectation technology. The Galaxy Note 3 has the newest bearing of OLED affectation technology. The lab tests appearance that it is bigger than the Note II in every altitude category, and aswell commensurable or bigger than the affectation on the Galaxy S4. It has bifold the resolution of the Note II, which is a aloft improvement, but the a lot of absorbing advance for the Note 3 is its absolutely brighter screen. We’ll awning these issues and abundant more, with all-embracing absolute affectation tests, abstracts and assay that you will acquisition boilerplate else.
OLED DisplaysWhile a lot of adaptable displays are still LCD based, OLEDs accept been capturing a rapidly accretion allotment of the adaptable affectation market. The technology is still actual new, with the Google Nexus One Smartphone, launched in January 2010, as the aboriginal OLED affectation artefact that accustomed boundless notoriety. In a bulk of just a few years this new affectation technology has bigger at a actual absorbing rate, now arduous and even beyond the accomplishment of the best LCDs. Around all of the OLED displays in accepted adaptable accessories are produced by Samsung Display. We accept provided an all-embracing assay on the change of OLEDs in our Galaxy S I,II,III OLED Affectation Technology Shoot-Out and Galaxy S4 Affectation Technology Shoot-Out articles.
Samsung provided DisplayMate Technologies with a pre-release assembly assemblage to assay and assay for this Affectation Technology Shoot-Out article.
The Shoot-OutTo appraise the accomplishment of the Samsung Galaxy Note 3 we ran our all-embracing alternation of Mobile Affectation Technology Shoot-Out Lab tests and included theGalaxy Note II in adjustment to actuate how OLED displays accept improved. We yield affectation superior actual actively and accommodate all-embracing cold assay side-by-side comparisons based on abundant chic abstracts and all-encompassing examination tests with both assay patterns and assay images. To see how far adaptable displays accept progressed in just three years see our 2010 Smartphone Affectation Shoot-Out, and for a absolute history assignment see our aboriginal 2006 Smartphone Affectation Shoot-Out.
Results HighlightsIn this After-effects area we accommodate Highlights of the absolute Lab abstracts and all-encompassing side-by-side beheld comparisons appliance assay photos, assay images and assay patterns that are presented below. The Comparison Table area summarizes the Lab abstracts in the afterward categories: Screen Reflections, Brightness and Contrast, Colors and Intensities, Viewing Angles, OLED Spectra, Display Power. You can aswell skip the Highlights and go anon to the Conclusions.
The Galaxy Note 3 has the newest bearing of Samsung OLED displays back the Galaxy S4 Smartphone, which launched in April. The Lab tests beneath appearance that it is bigger than the Note II in every altitude category, and aswell commensurable or bigger than the Galaxy S4. It has bifold the resolution of the Note II, which is a aloft improvement, but the a lot of important advance for the Note 3 is its absolutely brighter screen.
Impressive BrightnessUp until the Galaxy Note 3, OLED displays accept been somewhat to absolutely dimmer than aggressive LCD displays. The Note 3 has afflicted that in a big way…it’s an absorbing 55 percent brighter than the Note II and a solid 25 percent brighter than the Galaxy S4. For a lot of angel agreeable it provides over 400 cd/m2, commensurable or college than a lot of LCD displays in this admeasurement class. Even added absorbing is that if Automatic Accurateness is angry on, the Note 3 hits an absurd 660 cd/m2 in top ambient light, area it’s bare (85 percent brighter than the Note II and 40 percent brighter than the Galaxy S4 with Automatic Brightness) – the brightest adaptable affectation we accept anytime activated in the Shoot-Out series. An absorbing accomplishment for OLEDs!
Multiple Awning Modes and Blush ManagementMost Smartphones and Tablets alone accommodate a individual anchored branch set affectation calibration, with no way for the user to adapt it based on claimed preference, the active application, or the ambient ablaze level. An important adequacy provided by the added contempo Galaxy Note and Galaxy S Smartphones is the admittance of a bulk of Awning Modes that accommodate altered levels of user selectable blush assimilation and affectation adjustment based on user and appliance preferences. The Galaxy Note 3 has 5 user selectable Awning Modes: Adapt Display, Dynamic, Standard, Professional Photo, and Movie, which we altercate beneath and cover abstracts for several Modes. The Awning Modes crave the accomplishing of Blush Administration to acclimatize the built-in Blush Gamut of the affectation added added branch adjustment for anniversary Mode.
Color Gamut and Absolute Blush AccuracyThe Note 3 Movie Approach delivers the a lot of authentic Blush and White Point adjustment for the Accepted sRGB/Rec.709 customer agreeable that is acclimated for around all agenda camera, HDTV, internet, and computer content, including photos and videos. Use the Movie Approach for the best blush and angel accuracy. The abstinent Absolute Blush Accurateness for the Movie Approach is an accomplished 3.1 JNCD. See this Figure for an account of JNCD. The Adapt Affectation Approach is the absence approach for the Galaxy Note 3 – it provides adaptive angel processing and delivers college blush saturation, which appeals to some, and is aswell a bigger best for top ambient ablaze examination conditions, which ablution out angel colors and contrast. This approach is actual agnate to the Professional Photo Mode, but has a added bluish White Point. Analyze the Blush Gamuts in this Figure and below.
Professional Photo ModeMost high-end agenda cameras accept an advantage to use the Adobe RGB Gamut, which is 17 percent beyond than the Accepted sRGB/Rec.709 Gamut acclimated in customer cameras. The Professional Photo Approach on the Note 3 provides a adequately authentic adjustment to the Adobe RGB standard, which is rarely accessible in consumers displays, and is actual advantageous for high-end agenda photography applications. The abstinent Absolute Blush Accurateness of the Professional Photo Approach is 4.4 JNCD, which is Actual Good. See this Figure for an account of JNCD.
Performance in Top Ambient Lighting
Mobile displays are generally acclimated beneath almost ablaze ambient lighting, which washes out angel colors and contrast, abbreviation account superior and authoritative it harder to apprehend the screen. To be accessible in top ambient ablaze a affectation needs top awning Accurateness and low awning Reflectance – the Note 3 has both. In fact, with Automatic Accurateness angry on, the Note 3 has the accomplished Adverse Rating for Top Ambient Ablaze we accept anytime measured, which quantitatively measures awning afterimage beneath ablaze ambient lighting – the college the better. This article has awning shots that appearance how awning images abase in Top Ambient Lighting. On the Note 3 the Accurateness can be set abundant college for Automatic Accurateness so that users can’t assuredly set the Manual Accurateness slider to actual top values, which would run down the array quickly. This added top akin of Accurateness is alone bare for top Ambient Light. In addition, the Adapt Display, Accepted and Dynamic Modes aswell accept abundant college Blush Saturation, which aswell improves awning afterimage in top Ambient Light.
Viewing Bend PerformanceWhile the Note 3 is primarily a individual eyewitness device, the aberration in affectation accomplishment with examination bend is still actual important because individual admirers frequently authority the affectation at a array of examination angles. The bend is generally up to 30 degrees, added if it’s comatose on a table or desk. While LCDs about acquaintance a 55 percent or greater abatement in accurateness at a 30 bulk Examination Angle, the Note 3 shows a abundant abate 22 percent abatement in accurateness at 30 degrees. This aswell applies to assorted side-by-side admirers as well, and is a cogent advantage for OLED displays.
A Abounding HD 1920x1080 DisplayThe Galaxy Note II (like the Galaxy S III) has a 1280x720 display. The Galaxy Note 3 (like the Galaxy S4) provides a abounding Top Definition 1920x1080 display, with added than bifold the bulk of pixels – the aforementioned pixel resolution as your 50 inch active allowance HDTV – that’s actual impressive! Aboriginal of all, this is a criterion blueprint with amazing business ability for active customer sales. But there are added important affidavit for traveling to Abounding HD – there is a amazing bulk of 1920x1080 agreeable available. Displaying that agreeable at its built-in resolution (without the charge to rescale up or down) after-effects in the best accessible angel quality, added rescaling requires processing aerial that uses (wastes) adored array power.
Image Accurateness and Pixels Per InchThe Galaxy Note 3 has a pixel body of 388 Pixels Per Inch PPI, which is actual high, but lower than the 441 PPI for the Galaxy S4 and added Abounding HD Smartphone displays. It’s important to admit that this is not a abatement in beheld angel accurateness because the affectation still appears altogether aciculate for 20/20 Vision at archetypal examination distances of 13 inches or added because the Pixels and Sub-Pixels are beneath accustomed beheld acuity. (The Galaxy Note is 14 percent beyond than the Galaxy S4 so it is about captivated added away). The Galaxy Note 3 aswell has a PenTile Sub-Pixel adjustment like the Galaxy S4, with alone 2 Sub-Pixels per Pixel instead of the accepted 3. But at these actual top PPIs, it’s not visually apparent because of the use of Sub-Pixel Rendering and the Architecture Sub-Pixel adjustment discussed below. For added advice on beheld angel accurateness see High PPI PenTile Displays and Visual Accurateness and Resolution.
Diamond PixelsA top resolution awning attempt of the Galaxy Note 3 (provided by Samsung) shows an absorbing architecture and sub-pixel arrangement, which Samsung calls Diamond Pixels. Aboriginal of all, the Red, Green, and Blue sub-pixels accept actual altered sizes – Blue is by far the bigger because it has the everyman efficiency, and Green is by far the aboriginal because it has the accomplished efficiency. The alternating Red and Blue sub-pixel PenTile adjustment discussed aloft leads to a 45 bulk askew agreement in the sub-pixel layout. Then, in adjustment to aerate the sub-pixel packing and accomplish the accomplished accessible PPI, that leads to architecture rather than aboveboard or band shaped Red and Blue sub-pixels. But not for the Green sub-pixels, which are egg-shaped shaped because they are awkward amid two abundant beyond and altered sized Red and Blue sub-pixels. It’s affectation art.
Power EfficiencyWe abstinent an absorbing 26 percent advance in ability ability amid the Galaxy Note 3 and Note II. While LCDs abide added ability able for images with mostly white agreeable (like argument screens, for example), OLEDs are added able for darker agreeable because they are emissive rather than transmissive like LCDs. In fact, the Galaxy Note 3 is 31 percent added ability able than the Full HD LCD Smartphones we afresh activated for alloyed angel agreeable (that includes photos and videos, for example) with a 50 percent Average Account Level, APL.
Screen UniformityOne attenuate but important advantage of OLEDs is their accomplished awning accord compared to LCDs, which generally appearance hot spots and caliginosity from bend LED lighting.
Viewing TestsThe Galaxy Note 3 Movie Approach provides actual nice, pleasing, and authentic colors and account quality. The Movie Approach is recommended for calm and low ambient ablaze viewing. The Adapt Affectation and Accepted Modes accept absolutely added active and saturated colors. Some humans like that. They are recommended for average levels of ambient ablaze examination because it offsets some of the reflected blaze that washes out the images. The Dynamic Approach provides abundantly able colors that are cutting in low ambient lighting. The Dynamic Approach is recommended for top ambient ablaze viewing, for some amateur and cartoons, and possibly for bodies with beheld impairments.
Comparison with the Galaxy Note IIThe Galaxy Note 3 affectation is a aloft accessory and advance over the Galaxy Note II – a acceptable acumen to accede trading up. The Abounding HD 1920x1080 affectation on the Galaxy Note 3 has added than bifold the bulk of pixels and is acutely bluff again the lower resolution HD 1280x720 affectation on the Note II, absolutely with argument and graphics. But the a lot of arresting aberration is the 55 percent brighter affectation on the Note 3 (and 85 percent brighter with Automatic Brightness). Consistent with the differences in their Blush Gamuts and Acuteness Scales, the Movie Approach was hardly added active on the Note 3 and the Accepted Approach hardly added active on the Note II.
Galaxy Note 3 Conclusions: An Absorbing OLED DisplayThe Galaxy Note 3 continues the accelerated and absorbing advance in OLED displays and technology. The aboriginal notable OLED Smartphone, the Google Nexus One, came in absolutely endure abode in our 2010 Smartphone Affectation Shoot-Out. In a bulk of just a few years OLED affectation technology is now arduous and even beyond the accomplishment of the best LCDs beyond the lath in brightness, contrast, blush accuracy, blush management, account quality, awning uniformity, and examination angles. OLEDs are aswell appreciably thinner than LCDs but still amount appreciably added to manufacture.
The Galaxy Note 3 has the newest bearing of OLED affectation technology. The Lab tests appearance that it is bigger than the Note II in every altitude category, and aswell commensurable or bigger than the affectation on the Galaxy S4. It has bifold the resolution of the Note II, which is a aloft improvement, but the a lot of absorbing advance for the Note 3 is its absolutely brighter screen, which hits an absurd 660 cd/m2 in top ambient light, the brightest adaptable affectation we accept anytime activated in the Shoot-Out series. An absorbing accomplishment for OLEDs!
OLEDs charge to abide convalescent their ability efficiency, which is alarmingly important for adaptable displays. We abstinent an absorbing 26 percent advance in ability ability amid the Galaxy Note 3 and Note II. While LCDs abide added ability able for images with mostly white agreeable (like argument screens, for example), OLEDs are added able for darker agreeable because they are emissive rather than transmissive like LCDs. In fact, Galaxy Note 3 is already 31 percent added ability able than the Full HD LCD Smartphones we afresh activated for alloyed angel agreeable (that includes photos and videos, for example) with a 50 percent Average Account Level, APL. If this keeps up again OLEDs may cull avant-garde of LCDs in absolute ability ability in the abreast future.
What’s Next: The a lot of important developments for the accessible ancestors of both OLED and LCD adaptable displays will appear from improvements in their angel and account superior in ambient light, which washes out awning images, consistent in bargain readability, angel contrast, and blush assimilation and accuracy. The key will be in dynamically alteration the display’s blush administration and acuteness scales in adjustment to automatically atone for reflected blaze and angel ablution out from ambient light. See this commodity on affectation accomplishment in ambient light. The displays and technologies that accomplish in implementing this new action will yield the advance in the next ancestors of adaptable displays.
