Abstract: This application provide a display module and an electronic device, to reduce a probability of a display flicker. A display module includes a display, a display driver circuit, and at least one driver group; the display includes M rows of sub pixels; each driver group includes M gating circuits; an Nth gating circuit is configured to: receive a first initial voltage Vinit1 and a second initial voltage Vinit2 from the display driver circuit, output the second initial voltage Vinit2 to a second electrode of a first reset transistor and a first electrode of a voltage modulation transistor, and output the first initial voltage Vinit1 to the second electrode of the first reset transistor and the first electrode of the voltage modulation transistor.

Abstract: Methods and apparatuses for controlling brightness of a display are disclosed in the present disclosure. One method includes: determining a first brightness value of a display at a current brightness adjustment level; determining, based on a gamma correction lookup table, a first input grayscale value corresponding to the first brightness value, wherein the gamma correction lookup table comprises a gamma correction relationship between a brightness value of the display and an initial input grayscale value of the display at a predetermined brightness adjustment levels; and controlling an output brightness value of the display based on the first input grayscale value.
