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.

Abstract: This application provides a method and an apparatus for increasing a touch response speed. In this method, after a part of transmit channels are scanned, touch data obtained through scanning is immediately transmitted to an application processor. In addition, a subsequent transmit channel scanning process is performed while the touch data is transmitted, so that the transmit channel scanning process and the touch data transmission process are performed synchronously. After all transmit channels are scanned, a part of touch data obtained through the last scanning needs to be transmitted. Time required for transmitting a part of touch data is far less than time required for transmitting all touch data. Therefore, additional time required for transmitting data to the application processor is greatly reduced, so that time required for an entire touch response process is reduced, and a response speed of a touch operation is finally increased.

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.
