In lab tests analyzing screens, the super AMOLED Quad HD (2560×1440) display panel of the Galaxy Note 5 was rated as “the best performing smartphone display" by DisplayMate, a U.S.-based group that routinely performs thorough testing of display quality on a variety of electronics.
According to evaluation results published by DisplayMate on Aug. 19 (Korean time), the Galaxy Note 5 broke its own records in the main evaluation items, including screen brightness, color accuracy, and power consumption, recording its best-ever results. DisplayMate said that the Galaxy Note 5 overtook the performance of its predecessor, the Galaxy Note 4, and the Galaxy S6, which was released half a year ago, raising the standard of displays once again.
Even though the Galaxy Note 5, which features the 5.7 in, 2560x1440 display, has the same screen size and resolution as last year's Note 4, Samsung significantly improved the display performance in terms of outdoor readability, including brightness and reflectance, and power efficiency. Screen brightness and reflectance have the biggest effects on the outdoor readability of the display. When the display has a higher level of peak brightness and a lower level of reflectance, users can enjoy better readability and image quality outside.
The Galaxy Note 5 has a screen reflectance of 4.7 percent, which is the lowest level in the industry, and a near-infinite contrast ratio, securing clearer images and better readability under any usage environment.
Under the strong rays of the sun, the Galaxy Note 5 has a peak display brightness of 861 cd/m2, up 14.8 percent from the Galaxy Note 4 with 750cd/m2. The figure is also nearly 10 percent brighter than the Galaxy S6, which was launched this year, with 784cd/m2. The candela per square meter (cd/m2) is the unit frequently used to specify the brightness of a display device. One candela is equivalent to the radiating power of a light with the intensity of one candle.
Despite the brighter screen, the Galaxy Note 5 is more power efferent than its predecessor. Based on a lab test on white wallpaper with the same brightness, the Galaxy Note 4 consumes 1.80 watts, while the Galaxy Note 5 consumes 1.49 watts, showing a 21 percent power improvement.
The increase in power consumption is inevitable for brighter screens. However, Samsung Electronics has significantly improved its display power consumption efficiency by improving performance of organic materials of red, green and blue.
