Abstract: Embodiments of this application provide a method, an apparatus, and a device for screen display, and a storage medium. Spectral information of light of a plurality of sub-colors in an original color light color gamut of a screen display picture is obtained separately. A melanopic lux per photopic lux ratio of the light of the sub-colors is calculated based on the spectral information of the light of the sub-colors. Sub-color light having a melanopic lux per photopic lux ratio that exceeds a preset melanopic lux per photopic lux ratio standard is eliminated from the original color light, so that the screen displays updated color light, where the preset melanopic lux per photopic lux ratio standard is a standard set based on a goal of reducing melatonin inhibition. The sub-color light is eliminated in a targeted manner based on the preset melanopic lux per photopic lux ratio standard.
