The phenomenon of light leakage is caused by the structural characteristics of the liquid crystal display itself. To a certain extent, it is a normal phenomenon. That is, the close match between the liquid crystal on the screen and the frame results in direct transmission of the light out of the lamp. The light leakage from the liquid crystal display is a common problem, in a sense. The liquid crystal display basically cannot prevent the occurrence of light leakage.
The characteristic of LED TVs is that the brightness of the backlight is too high and the white is dazzling. Obviously, the brighter the backlight, the more light is leaking. Therefore, backlight adjustment must be performed. However, this adjustment may not be found in the regular menu. Reducing the backlight from 100 to 0-20, while adding a little bit of conventional brightness and contrast, a miracle emerged: the light leakage that occurred in the original lighting situation disappeared completely! There is no need to worry about reducing the backlight will affect the picture effect, the fact is just the opposite. The brightness is still sufficient, the color is still bright, but the screen is no longer harsh and more comfortable to watch. If you turn off the light and turn off the matrix backlight function, there will be some light leakage with the all-black picture test, but it will not affect the turn-on display.
This adjustment is also necessary for TV users who do not leak light. The advantages are: After adjustment, black is deeper, and white is normalized from the original glare. As a result, the picture quality has improved and the comfort has been greatly improved. This is especially important for children's eye protection. At the same time, TV power is reduced and electricity bills are saved.
