Liquid crystal display and low-blue-ray display control system and low-blue-ray display method thereof

Abstract

The invention provides a liquid crystal display and a low-blue-ray display control system and low-blue-ray display method thereof. The low-blue-ray display method of the liquid crystal display comprises partitioning a backlight source to obtain a plurality of backlight partitions which contain a first light emitting peak and a second light emitting peak, wherein the first light emitting peak is higher than the second light emitting peak; separately calculating the blue ray proportion of the display frame corresponding every backlight partition to acquire the blue ray proportion of every backlight partition; according to the blue ray proportion of every backlight partition, driving the first light emitting peak and / or the second light emitting peak. The low-blue-ray display method can ensure no offset of white dot coordinates and no reduction in display range when short-wave blue ray energy is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display, a low blue light display control system and a low blue light display method thereof. Background technique [0002] The medical profession has reached a consensus that the blue light of the display will cause visual fatigue and damage to the human eye. In order to reduce the visual harm of the blue light of the display to the human eye, people have made a lot of efforts. Generally speaking, it is mainly divided into software methods and hardware methods. The software method is gradually not accepted by the market because it is easy to cause the screen to turn yellow. The hardware method It is mainly achieved by changing the light-emitting wavelength of the blue light chip of the backlight and the matching color film photoresist. Taking into account the color coordinates of the white point of the display and the size of the color gamut in th...

In order to reduce the visual harm of the blue light of the display to the human eye, people have made a lot of efforts. Generally speaking, it is mainly divided into software methods and hardware methods. The software method is gradually not accepted by the market because it is easy to cause the screen to turn yellow. The hardware method It is mainly achieved by changing the light-emitting wavelength of the blue light chip of the backlight and the matching color film photoresist. Taking into account the color coordinates of the white point of the display and the size of the color gamut in the hardware mode, the extreme position of the blue light peak in the low blue light backlight can only be around 460nm. Further red-shifting the peak of the blue light will lead to a reduction in the display color gamut and a shift in the color coordinates of the white point, which is not conducive to the improvement of the quality of the display screen. At present, there is no good solution for this situation.
