●  Benchmarking

The instrument used in this test is the BM-7A brightness colorimeter produced by Topcon to measure the chromaticity coordinates of each TV in different colors, calculate the contrast, true color, color temperature, color saturation and draw the corresponding color characteristic diagram according to the corresponding values. Before this test, we first let the machine work normally for one hour continuously and restore it to the factory mode. The whole test environment is conducted in the darkroom.

　　（ OLED TV on the left and LCD TV on the right ）

OLED realizes pure black (the indicator light proves the power on status)/LCD leaks light seriously (the dynamic contrast is turned on)

OLED full color

LCD picture is not soft enough, which is easy to damage vision

OLED color restoration is true and accurate

In fact, the LCD backlight system is the culprit of destroying the screen image quality. The relatively mediocre color performance of the LCD is further "diluted" by the backlight, which further weakens the color performance, and the user cannot see the most realistic picture scene. OLED display technology avoids the problem of light leakage without backlight self illumination, and realizes true pure black, red green blue primary colors will not be damaged by backlight, bringing users the most authentic color performance.

The bottom color pointed by the arrow and the color scale transition within the circle

From a color test chart, it can be seen that due to the interference of backlight, LCD technology cannot restore the true blue at the bottom of the screen, while OLED can display the original light blue. This is because OLED color display is full, LCD color is not true to OLED, and the influence of backlight leads to the color that should be displayed is not true. Pay attention to the color scale transition in the white circle. The transition between OLED colors is clear, while the original colors in the last row of the LCD are "blackened". The color scale display is not complete, and the performance of dark details is inferior to that of OLED display technology.
