The Best Smartphone Display (It's Not Who You Think)


Samsung provided DisplayMate Technologies with a pre-release production unit of the Galaxy S5 so that we could perform our well known objective and comprehensive display Lab tests, measurements, and analysis, explaining the in-depth OLED display performance smartphones display test for consumers, reviewers, smartphones display test, and journalists. While many people have assumed that the Galaxy S5 has basically the same display as the Galaxy S4, but just a bit bigger, that isn't the case, smartphones display test.

Our detailed Lab tests show that there have been significant display performance improvements in almost every single test and measurement category,resulting in a number of new records for smartphone display performance, smartphones display test.

Based on our extensive Lab tests and measurements, which we present in detail below, the Galaxy S5 is the best performing smartphone display that we have ever tested—and it has raised the bar for top display performance up by another notch.

With the Galaxy S5 the emphasis has shifted from the traditional yearly increases in resolution, screen size, and pixels per inch ppiwhich have dominated the headlines for the last 10 years. These have now played out as far as visually beneficial, so it's time for manufacturers, consumers and reviewers to shift their attention and concentrate on the many other even more important display performance issues that we smartphones display test discuss in detail below.

There are, smartphones display test, however, other benefits in moving up to somewhat higher resolutions, so future generations of smartphones will likely go up to a 2. There are many more important and challenging issues for displays than smartphones display test pixel resolution.

We'll cover these issues and much more, with in-depth comprehensive display tests, measurements and analysis that you will find smartphones display test else. The technology is still very new, with the Google Nexus One smartphone, launched in Januaryas the first OLED display product that received widespread notoriety. In a span of just a few years this new display technology has been improving at a very impressive rate, now challenging and even exceeding the performance of the best LCDs.

We take display quality very seriously and provide in-depth objective analysis based on detailed laboratory tests and measurements and extensive viewing tests with both test patterns, test images and test photos. To see how far OLED and LCD mobile displays have progressed in just smartphones display test years see our smartphone display Shoot-Outand for a real history lesson see our original smartphone display Shoot-Out.

In this results section we provide Highlights of the comprehensive Lab tests and measurements and extensive visual comparisons using test photos, test images, and test patterns that are covered in the advanced sections, smartphones display test.

You can also skip these highlights and go directly to the conclusions. Those results together with the Lab tests and measurements below show that the Galaxy S5 display is a major improvement over the Galaxy S4 and a significant improvement over the Galaxy Note 3 in almost every single test and measurement category, smartphones display test, which we cover below.

It's an impressive 22 percent brighter than the Galaxy S4 and a solid 13 percent brighter than the Galaxy Note 3. As discussed below, the very low screen Reflectance of the Galaxy S5 further improves the effective Screen Brightness in high Ambient Light.

An impressive achievement for OLED technology! See the Brightness and Contrast section for measurements and details. This is useful for working comfortably without eye strain or bothering others in very dark environments, or affecting the eye's dark adaptation, such as when using a telescope. The display still delivers Full bit color and the picture quality remains excellent. Most smartphones and tablets only provide a single fixed factory set display calibration, with no way for the user to alter it based on personal preferences, running applications, or ambient light levels.

An important capability provided by the more recent Galaxy S and Galaxy Note smartphones is the inclusion of a number of screen modes that provide different levels smartphones display test user selectable color saturation and display calibration based on user and application preferences. The Galaxy S5 has 5 user selectable screen modes: adapt display, smartphones display test, dynamic, standard, professional photo, and cinema, which we discuss below and include detailed measurements for three of the modes.

The screen modes require the implementation of color management in order to adjust the native color gamut of the display, plus additional factory calibrations for each screen mode. See the colors and intensities section for measurements and details.

The Absolute Color Accuracy for the cinema mode is an excellent 2. Use the cinema mode for the best color and image accuracy, which is especially important when viewing photos from family and friends because you often know exactly what they actually should look likefor some TV shows, movies, and sporting events with image content and colors that you are familiar with, and also for viewing online merchandise, smartphones display test you have a good idea of exactly what colors you're buying and are less likely to return them.

See the color accuracy section and color accuracy plots for measurements and details. The Professional Photo Mode on the Galaxy S5 provides an 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 measured absolute color accuracy of the professional photo mode for the Galaxy S5 is 3.

There are very few displays that can accurately reproduce Adobe RGB, so this is a significant plus for serious photography enthusiasts. The Adapt Display Mode provides real-time adaptive processing to dynamically adjust images and videos —for some applications it will vary the White Point, Color Gamut, and Color Saturation based on the smartphones display test content and the color of the surrounding ambient lighting measured by the Galaxy S5 RGB Ambient Light Sensor which measures color in addition to brightness.

The Adapt Display Mode also delivers higher color saturation, which appeals to some, and is also a better choice for high ambient light viewing conditions, which wash out the on-screen colors and contrast from the reflected light, smartphones display test, which we examine next. Mobile displays are often used under relatively bright ambient light, which washes out image colors and contrast, smartphones display test, reducing picture quality and making it harder to view or read the screen.

To be usable in high ambient light a display needs a dual combination of high screen Brightness and low screen Reflectance — the Galaxy S5 has both. For Screen Reflectance, the Galaxy S5 with 4. See the Brightness and Contrast and Screen Reflections sections for measurements and details. Our Contrast Rating for High Ambient Light quantitatively measures screen visibility under bright Ambient Light — the higher the better. As a result of its high Brightness and low Reflectance, the Galaxy S5 has a Contrast Rating for High Ambient Light that ranges from 75 toalso the highest that we have ever measured.

Screen Shots in Ambient Light : This article with screen shots shows how many smartphones and tablets degrade in high ambient lighting. On the Galaxy S5 the Brightness can be set much higher for automatic brightness so that users can't permanently park the manual brightness slider to very high values, which would run down the battery quickly.

This extra high level of brightness is only needed for high Smartphones display test Light. Color Washout in Ambient Light : The adapt smartphones display test mode delivers higher color Saturation, which appeals to some, and is also a better choice for high Ambient Light viewing conditions, which wash out the on-screen colors and contrast from the reflected light off the screen.

For smartphones display test, in 0 lux absolute darkness the adapt display mode has a Color Gamut that has percent of the Standard Color Gamut, but at 1, lux ambient light, which corresponds to high indoor or low outdoor lighting levels, the Color Gamut falls to 99 percent, while for the cinema mode it falls to smartphones display test percent at 1, lux, so the higher Color Gamuts are best in high ambient light.

See the Colors and Intensities section for measurements and details. For an in-depth discussion see our visual sharpness and display resolution section, smartphones display test, which explains the many issues that come into play.

A high resolution screen shot of the Galaxy S5 and 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 smartphones display test lowest efficiency, and Green is by far the smallest because it has the highest smartphones display test. The alternating red and blue sub-pixel arrangement leads to a 45 degree diagonal symmetry in the sub-pixel layout.

This allows vertical, horizontal, and particularly diagonal line segments and vectors to be drawn with reduced aliasing and artifacts. In order to maximize the sub-pixel packing and achieve the highest possible pixels per inch ppithat leads to diamond rather than square or stripe shaped red and blue smartphones display test. But not for the green sub-pixels, smartphones display test, which are oval shaped because they are squeezed between two much larger and different sized red and blue sub-pixels.

It's a form of high-tech display art. The Galaxy S5 display delivers 22 percent higher brightness than the Galaxy S4 with the same display power. Taking into account its 4 percent larger screen area, the Galaxy S5 has an impressive 27 percent improvement in display power efficiency over the Galaxy Smartphones display test. Turning this around, for the same screen Brightness the Galaxy S5 uses 18 percent less display power than the Galaxy S4, which helps improve the running time on battery.

The Galaxy S5 also has an Ultra Power Saving Mode that lowers the Screen Brightness and also sets the background to Black, both of which significantly reduce display power and can double the running time on battery. See the Display Power section for measurements and details. While LCDs remain more power efficient for images with mostly white content like text screens, for exampleOLEDs are more power efficient for most other content, which are typically darker, because they are emissive rather than transmissive like LCDs, smartphones display test.

While smartphones are primarily single viewer devices, the variation in display performance with viewing angle is still very important because single viewers frequently hold the display at a variety of viewing angles. The angle is often up to 30 degrees, more if it's resting on a table or desk. While LCDs typically experience a 55 percent or greater decrease in brightness at a 30 degree Viewing Angle, the Galaxy S5 shows a much smaller 22 percent decrease in Brightness at 30 degrees.

This also applies to multiple side-by-side viewers as well, and is a significant advantage of OLED displays. The Color Shifts with Viewing Angle are also relatively small. See the viewing angles section for measurements and details. The Galaxy S5 Cinema Mode provides very nice, pleasing and smartphones display test colors, and picture quality.

Although the Image Contrast and Color Saturation are slightly too high due to a slightly too steep Intensity Scalethe very challenging set of DisplayMate Test and Calibration Photos that we use to evaluate picture quality looked Beautiful, even to my experienced hyper-critical eyes.

The cinema mode is recommended for indoor and low ambient light viewing of most standard consumer content for digital camera, HDTV, internet, smartphones display test, and computer content, including photos, videos, and movies. The adapt display mode has significantly more vibrant and saturated colors. Some people like that, smartphones display test. It is also particularly recommended for medium and high levels of ambient light viewing because it offsets some of the reflected glare that washes out the images.

Smartphones display test primary goal of this Display Technology Shoot-Out article series has always been to point out which manufactures and display technologies are leading and advancing the state-of-the-art of displays by performing comprehensive and objective Lab tests and measurements together with in-depth analysis.

We point out who is leading, who is behind, who is improving, and sometimes unfortunately who is back pedaling, all based solely on the extensive objective measurements that we also publish, so that everyone can judge the data for themselves as well.

In a span of just four years OLED display technology is now challenging smartphones display test even exceeding the performance of the best LCDs across the board smartphones display test brightness, contrast, color accuracy, color management, picture quality, performance in high ambient light, smartphones display test uniformity, and viewing angles. While many people have assumed that the Galaxy S5 has basically the same display as the Galaxy S4, but just a bit bigger, that isn't the case… Our detailed Lab tests show that the Galaxy S5 display is a major improvement over the Galaxy S4 and a significant improvement over the Galaxy Note 3 in almost every single test and measurement category—a good reason to consider upgrading.

Best Smartphone Display: Based on our extensive Lab tests and measurements, the Galaxy S5 is the Best performing smartphone display that we have ever tested. The Galaxy S5 has raised the bar for top display performance up by another notch—an impressive achievement for OLED technology.

Most Accurate Colors: The Galaxy S5 cinema mode has the most accurate colors for any smartphone or tablet display that we have ever measured. This is especially important when viewing photos from family and friends because you often know exactly what they actually should look likefor some TV shows, movies, and sporting events with image content and colors that you are familiar with, and also for viewing online merchandise, so you have a good idea of exactly what colors you're buying and are less likely to return them.

Although the Image Contrast and Color Saturation are slightly too high due to a slightly too steep Intensity Scalethe very challenging set of DisplayMate Smartphones display test and Calibration Photos that we use to evaluate Picture Quality looked Beautiful, even to my experienced hyper-critical eyes. The Cinema Mode is recommended for indoor and low ambient light viewing of most standard consumer content for digital camera, HDTV, internet, and computer content, including photos, smartphones display test, videos, and movies.

The Adapt Display Mode has significantly more vibrant and saturated colors. Power Efficiency: OLEDs need smartphones display test continue improving their power efficiency, which is critically important for mobile displays.

We measured an impressive 27 percent improvement in display power efficiency between the Galaxy S5 and S4. According to Samsung, this increase is due to more efficient OLED materials and also to improvements in the display electronics and optics. While LCDs remain more power efficient for images with mostly white content like text screens, for exampleOLEDs are now more power efficient for most other content, which are typically darker, because they are emissive displays rather than transmissive like LCDs.

Upcoming Smart Watch Display Shoot-Outs: For smartwatches the software is evolving rapidly and you will be able to regularly download software updates and new Apps as they improve—but the display cannot be updated so choose carefully, smartphones display test. For smartwatches the display is the essential key for a great product, and a major challenge because it needs to be very small, very thin, and have major power constraints to maintain a greater than 1 day battery running smartphones display test, yet it must deliver bright images in very high ambient light, produce vibrant high resolution colored text and smartphones display test, and provide great picture quality and color accuracy for photos and videos.

Samsung has also provided DisplayMate Technologies with the new Galaxy Gear 2 smartwatches that have high resolution OLED color displays, which we will be testing and evaluating next. After that we'll produce a full Smartwatch Display Technology Shoot-Out, smartphones display test, where we will objectively measure the display performance of the most interesting smartwatch displays and display technologies.

To stay informed Follow DisplayMate on Twitter, smartphones display test. What's Next: The most important developments for the upcoming generations of both OLED and LCD mobile displays will come from improvements in their image and picture quality in ambient light, which washes out screen images, resulting in reduced readability, image contrast, and color saturation and accuracy.

The key will be in dynamically changing the display's color management and intensity scales in order to automatically compensate for reflected glare and image wash out from ambient light as discussed in our Innovative Displays and Display Technology and SID Display Technology Shoot-Out articles. The displays and technologies that succeed in implementing this new strategy will smartphones display test the lead in the next generations of mobile displays. Below we examine in-depth the display on the Samsung Galaxy S5 based on objective Lab measurement data and criteria.
