ディスプレイモジュール及びその制御方法、ディスプレイ駆動回路、並びに電子デバイス

Japanese Patent JP7430245

B2

A display module and a control method thereof, a display drive circuit, and an electronic device are disclosed, and relate to the field of display technologies, to mitigate a display flicker phenomenon when a display (10) displays an image at a low refresh rate. The display module includes a display (10), a display driver, and at least one driver group. The display (10) includes M rows of sub-pixels (20) arranged in a matrix form. Each sub-pixel (20) includes a driving transistor M4, a first reset transistor M1, a first capacitor Cst, and a light emitting device L. Each driver group includes M selecting circuits (301). The N^th selecting circuit (301) is coupled to a second node of a first reset transistor M1 in the N^th row of sub-pixels (20). The selecting circuit (301) is configured to output a second initial voltage Vint2 to the second node of the first reset transistor M1 when a pixel circuit (201) is in a reset phase and a data voltage writing phase, and is configured to output a first initial voltage Vint1 to the second node of the first reset transistor M1 when the pixel circuit (201) is in a light emitting phase, where |Vint2|>|Vint1|.
