Abstract

The invention provides a pixel charging method and an electronic device. The method comprises the following steps: determining the polarity of a voltage signal supplied by a multiplexing control circuit to a target data line among M data lines; if the polarity is the first polarity, controlling the duration of the voltage signal supplied to the target data line to be equal to the first charging duration; If the polarity is the second polarity, controlling the duration of the voltage signal supplied to the target data line to be equal to the second charging duration; the first charge duration is longer than the first minimum charge duration required when the sub-pixel is charged by the voltage signal of the first polarity; the second charge duration is longer than that of the sub-pixel whenthe sub-pixel is charged by the voltage signal of the second polarity, and the second minimum charge duration is smaller than that of the predetermined charge duration. The predetermined charge duration is longer than the second minimum charge duration and smaller than the first minimum charge duration. The invention can ensure that the sub-pixel charging time is sufficient.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a pixel charging method and an electronic device. Background technique [0002] When the display module is displaying, a driver IC (Integrated Circuit, integrated circuit) in the display module writes a voltage signal to each sub-pixel, charges the sub-pixel, and then controls the sub-pixel to display. [0003] However, in the prior art, there is a problem that the charging time of the sub-pixels is insufficient. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a pixel charging method and an electronic device to solve the problem of insufficient sub-pixel charging time. [0005] In order to solve the above-mentioned problems, the present invention is realized as follows: [0006] In a first aspect, an embodiment of the present invention provides a pixel charging method, which is applied to an electronic device....
