Comparing Displays on the Galaxy S III and Galaxy S4
The Galaxy S4 display is a major enhancement and improvement over the Galaxy S III – a good reason to consider trading up. The screen has Full HD 1920x1080 resolution with more than double the number of pixels and with 44 percent higher Pixels Per Inch than the Galaxy S III. It is 25 percent brighter (and up to 68 percent brighter with Automatic Brightness) and the display is 20 percent more power efficient. The Galaxy S4 also has 5 user selectable Screen Modes and delivers much better picture quality and color accuracy.
Comparing the Galaxy S4 with the LCD Display on the iPhone 5
The iPhone 5 is now more than half way through its product cycle, which is important to keep in mind for our comparison. However, high-end LCDs like the iPhone 5 are a very mature and refined display technology, so other than screen size, resolution, and the Pixels Per Inch not much is likely to change in the next generation, no matter what Apple decides to do. The iPhone 5 is significantly brighter than the Galaxy S4, particularly for screens with mostly peak white backgrounds. Its color calibration is a bit better, although the Galaxy S4 has a more accurate White. The Galaxy S4 has a much bigger screen, higher resolution, higher PPI, much darker blacks, and better screen uniformity than the iPhone 5. They each have their own particular strengths and weaknesses, but if you scan our color coordinated Comparison Table below, both displays are quite good and comparable overall – so it’s currently a tie – we’ll see how they both evolve and improve in the next generation…

Brightness and Power Efficiency
OLED displays are generally not as bright as the brightest LCD displays. There are two reasons for this: first, while OLED power efficiency has been steadily improving they are not yet as power efficient as the best LCDs. Second: there is a marketing obsession for producing ultra thin and light weight Smartphones, which sacrifices much needed battery power. Since the display often uses 50 percent or more of the total Smartphone power, various display power management schemes are frequently used. The Galaxy S4 uses one innovative approach to overcome this – when Automatic Brightness is turned on, the Peak Brightness becomes significantly brighter in high ambient lighting than is possible with Manual Brightness, up to as high as 475 cd/m2, which is 34 percent higher than is possible with Manual Brightness. This is done so that users can’t permanently set the brightness to very high values, which would run down the battery quickly.
Performance in High Ambient Lighting
Smartphones are never used in the dark. In fact, they are often used in very bright ambient lighting, which can significantly degrade and wash out their image and picture quality. The Galaxy S4 performs very well in high ambient lighting in spite of its typically lower screen brightness because it has one of the smallest screen Reflectance values of any display we have ever tested, and its more saturated colors can help cut through the reflected light glare. When Automatic Brightness is turned on, the screen brightness increases considerably at high levels of ambient lighting as mentioned above. The Galaxy S4 is then comparable or brighter than most LCD Smartphones, but still 15 percent less than the much smaller iPhone 5, which is the brightest Smartphone we have tested.
The Galaxy S4 Movie Mode provides very nice, pleasing, and accurate colors and picture quality. The Movie Mode is recommended for indoor and low ambient light viewing. The Standard Mode has significantly more vibrant and saturated colors. Some people like that. The Standard Mode is recommended for medium levels of ambient light viewing because it offsets some of the reflected glare that washes out the images. The Dynamic Mode provides incredibly powerful colors that are overwhelming in low ambient lighting. The Dynamic Mode is recommended for high ambient light viewing only. For all of the Modes a slight green color tint was sometimes noticeable, but not objectionable. It results from the Green primary being more saturated than the Red and Blue primaries, as shown in this Figure. Readjusting the internal color management could fix this…

Digital Display Technology
Most consumers are not aware that LCDs are actually non-linear analog displays that perform really well only as the result of highly refined electronics and careful factory calibration. This is the same reason why even living room HDTVs provide coarse and imprecise color and image controls, and why professional calibration is desirable. One interesting technical development is that the latest OLED displays use digital Pulse Width Modulation to specify the brightness of every sub-pixel. This makes it possible for OLED displays like the Galaxy S4 to precisely vary and directly digitally control their Intensity Scales, Gamma values, White Points, color calibration and color management of the display in firmware or software. Plasma and DLP displays also use digital Pulse Width Modulation, but the OLED displays perform better because of higher frequencies and faster response times.
One important application of the Digital Display Technology mentioned above is that this makes it relatively easy to provide a number of different display calibration options and settings that will appeal to differing consumer tastes and preferences under various viewing conditions and applications. The Galaxy S4 (like its bigger cousin the Galaxy Note II) includes 5 user selectable Screen Modes: Adaptive, Dynamic, Standard, Professional Photo, and Movie, which we discuss below and include measurements for the Standard and Movie Modes.
Color Gamut and Color Accuracy
The Galaxy S4 Movie Mode delivers the closest Color and White Point calibration to the standard sRGB/Rec.709 consumer content that is used for digital camera, HDTV, internet, and computer content, including virtually all photos and videos. Use the Movie Mode for the best color and image accuracy. Its Green primary is still somewhat too saturated – hopefully it will get toned down some as in the Galaxy Note II, which is very accurate. The Professional Photo Mode provides a fairly accurate calibration to the Adobe RGB standard, which is rarely available in consumers displays, and is very useful for high-end digital photography applications. The Standard Mode is the default mode for the Galaxy S4 – it delivers higher color saturation, which appeals to some, and is a better choice for high ambient light viewing conditions, which wash out image colors and contrast. This mode is very similar to the Professional Photo Mode, but has a more bluish White Point. Its Green primary is also too saturated, but noticeably less than in the Galaxy S III. The Dynamic Mode produces the most vibrant image and picture quality. Compare the Color Gamuts in this Figure and below.

The pixels on most current OLED displays have only 2 sub-pixels in each pixel instead of the standard 3 Red, Green, and Blue sub-pixels found in most other displays and display technologies. Half of the PenTile pixels have Green and Red sub-pixels and the other half have Green and Blue sub-pixels, so Red and Blue are always shared by two adjacent pixels. This makes PenTile displays easier to manufacture and at a lower cost. It also improves brightness and reduces aging effects. Because the eye has lower visual acuity for color this works very well for photographic and video images. But for digitally generated fine text and graphics with precise pixel layouts the eye can visually detect the reduced number of Red and Blue sub-pixels unless the number of Red and Blue Sub-Pixels Per Inch is very high. And it is for the Galaxy S4 – there are 312 Red and Blue Sub-Pixels Per Inch, which is only a few percent lower than Apple’s Benchmark 326 PPI iPhone Retina Display. Visually the Galaxy S4 PenTile display delivers excellent visual sharpness across the board.
A high resolution screen shot of the Galaxy S4 (provided by Samsung) shows an interesting design and sub-pixel arrangement, which Samsung calls Diamond Pixels. First of all, the Red, Green, and Blue sub-pixels have very different sizes – Blue is by far the largest because it has the lowest efficiency, and Green is by far the smallest because it has the highest efficiency. The alternating Red and Blue sub-pixel PenTile arrangement discussed above leads to a 45 degree diagonal symmetry in the sub-pixel layout. Then, in order to maximize the sub-pixel packing and achieve the highest possible PPI, that leads to diamond rather than square or stripe shaped Red and Blue sub-pixels. But not for the Green sub-pixels, which are oval shaped because they are squeezed between two much larger and different sized Red and Blue sub-pixels. It’s display art…
AnonD-98697, 29 Apr 2013Please don't waste your time with this kid, he is just trolling here and you are feeding him. ... morea website called displaymate specialized in screen analysis did a review of the galaxy s4 screen vs iphone 5 and proved that the galaxy s4 can produce accurate colors and here are the results:
A Full HD 1920x1080 Display
By far the most interesting recent development in Smartphones is a full High Definition 1920x1080 display in a 5.5 inch or smaller screen size – the same pixel resolution as your 50 inch living room HDTV – that’s very impressive! First of all, this is a benchmark spec with tremendous marketing power for driving consumer sales. But there are other important reasons for going to Full HD in a Smartphone – there is a tremendous amount of HD 1920x1080 content available. Displaying that content at its native resolution (without the need to rescale up or down) results in the best possible image quality, plus rescaling requires processing overhead that uses (wastes) precious battery power. The Galaxy S4 is one of the first few Smartphones to offer Full HD.
400+ Pixels Per Inch Displays
Apple started a major revolution in display marketing by introducing their “Retina Display” with 326 Pixels Per Inch (PPI) on the iPhone 4 in 2010. While not equivalent to the resolution of the human retina, people with 20/20 Vision cannot resolve the individual pixels when the display is held at normal viewing distances of 10.5 inches or more. It started a display PPI and Mega Pixel war similar to what happened with Smartphone digital cameras, which is still an ongoing wild goose chase now into the stratosphere… Hopefully the same thing won’t happen with mobile displays because there are tradeoffs involved that affect other important display performance issues. The real question is how high do we need to go before reaching a practical visual PPI limit? I’ll cover this in an upcoming article. However, a new generation of 400+ PPI displays is already here, driven by the desire to produce a Full HD 1920x1080 display on a Smartphone screen. The Galaxy S4 has an incredible 441 Pixels Per Inch. People with 20/20 Vision cannot resolve the individual pixels on a 441 PPI display for viewing distances of 7.8 inches or more, which is exceedingly close for viewing a 5.0 inch display.

AMOLED never and NEVER will have anything else than view angles and the dept black, the rest is crap.
The colors of AMOLED are just a joke and the white never will be white, is just a stupid try of green-white which is a design limitation of the technology of this display and cannot be removed.
good phone using since last 20 days it's a wow phone,Sony back in action

Let me tell you~
It's NATURAL COLORS...
Now I know why you never give up~
Because you are not sticking to the same topic...
Since first comment reply to you is all about display colors~
You are too busy bashing SONY product until you forget about the original title...
The statement you mentioned is about viewing angles not about colors~
If this counted, it won S4 in design catagory...
The second link~
You just posting it for the sake of "somewhat disappointing TFT display"...
The third link~
It's also about viewing angles...
The forth link~
It's about viewing angles and less contrast...
Somehow all the links given never came close to what we argue about~
That's NATURAL COLORS of AMOLED and LCD...
If you want me to keep quiet~
Just tell me you wanna talk about viewing angles...
But please remember~
You are the first who brought out "AMOLED has NATURAL COLORS"...
Then I gave links to let you know that AMOLED NEVER HAVE NATURAL COLORS~
Then you changed topic after that...
And for your information~
Those who wrote all the reviews are not SCIENTISTS...
You really try hard to keep SONY Xperia Z look bad~
Keep it up but also keep your facts right, accurate and never get off topic...
