Abstract

The invention discloses a method and a system for controlling blue light of a display screen of a display, a control device and the display. The method comprises the following steps: acquiring illuminance information of the display screen; generating a blue light hazard index according to the obtained illuminance information; and comparing the blue light hazard index with a preset safety value, and when the blue light hazard index is higher than the preset safety value, reducing the blue light hazard index of the display screen. By comparing the blue light hazard index with the preset safety value, when the blue light hazard index is higher than the preset safety value, the blue light hazard index of the display screen is reduced, so that the purpose of reducing the blue light is achieved.

Description

technical field [0001] The invention belongs to the technical field of displays, and in particular relates to a method, a system, a control device and a display for controlling blue light of a display screen of a display. Background technique [0002] The medical display in the display is a professional display specially used in the medical field. Compared with other displays, it has the characteristics of high brightness. For example, the brightness of the medical display can reach 1000cd / m 2 , is about 3 times that of ordinary display screens. At present, medical display screens generally use white LED backlight. The principle of white LED backlight to produce white light for the screen is that the blue light emitted by the blue LED chip first excites the light yellow phosphor to produce yellow-green or red light. It is then mixed with the remaining blue light of the chip to form white light, and its spectrum will have a blue light peak between 415 and 485nm, and the highe...
