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.

Abstract: This application provides a method for calculating position information in a touchscreen and an electronic device. In the method for calculating position information in a touchscreen, because a touch chip transmits, by using a high-speed serial bus, source data generated by a trigger operation, first duration t1 for the touch chip to transmit the source data generated by the trigger operation can be shorter. Because position information of the trigger operation in the touchscreen is calculated in a CPU, second duration t2 for the CPU to calculate coordinates of a position at which a user triggers the touchscreen can also be shorter.
