Luminescent display method, device, computer and storage medium for reducing blue light damage

Abstract

The invention provides a light-emitting display method and device reducing the blue light hazard, a computer apparatus and a storage medium. The method comprises the steps of: controlling a first LEDand a second LED to perform light-emitting display separately; correcting blue light emitted by the first LED and blue light emitted by the second LED to make the position of the color of the blue light emitted by the first LED in the color gamut coordinates and the position of the color of the blue light emitted by the second LED in the color gamut coordinates coincide. When a display screen displays images, the first LED with a blue light wavelength of 460nm-465nm and the second LED with a blue light wavelength of 435nm-440nm are adopted for light-emitting display; the blue light wavelengthof the first LED is greater, so that damage to the retina can be effectively avoided, and the second LED can reduce the total radiation energy of light emitted by the display screen, so that photochemistry damage to the retina can be reduced; by correcting the light-emitting color of the first LED and the second LED, metameric matching is realized and the display effect is better.

Description

technical field [0001] The present application relates to the technical field of luminescent display, in particular to a luminescent display method, device, computer and storage medium that reduce blue light damage. Background technique [0002] At present, the display screens of most electronic devices all adopt LED backlights, and these electronic devices are illuminated by blue light combined with warm-color phosphor powder. Therefore, when these electronic devices emit light to display, they will produce blue light. [0003] The shorter the wavelength of visible light, the greater the momentum and energy of photons, the greater the probability of destroying chemical bonds, stimulating more free radicals, and causing more damage on the molecular biological level; the lens in the human eye can absorb almost all Ultraviolet rays and most short-wave blue-violet light (this is why we cannot see ultraviolet light, and the Y value of blue-violet light has a low visual efficien...

Problems solved by technology

[0007] In order to reduce the adverse effects of using the display screen at night on sleep quality and physical and mental health, manufacturers have "anti-blue light mode / night mode" with different names. Most of these anti-blue light methods actively reduce the opening degree of the blue channel in the screen. Reduce the amount of blue light, which will cause the display to appear yellowish

In addition, it is also possible to reduce the total amount of blue light by originally designing a display module with a low color temperature, thereby reducing the harm caused by blue light, or, instead of using the blue channel, the pixels only use red and green channels. These practices will undoubtedly lead to yellowing of the displayed picture, resulting in poor display effect of the screen.
