Abstract
A display module, a display drive circuit, and an electronic device. The display module includes a display and at least one driver group. The display includes M rows of sub-pixels arranged in a matrix form. Each sub-pixel includes a driving transistor, a first reset transistor, a first capacitor, and a light emitting device. Each driver group includes M selecting circuits. The Nth selecting circuit is coupled to a second node of a first reset transistor in the Nth row of sub-pixels. The selecting circuit is configured to output a second initial voltage Vint2 to the second node, and is configured to output a first initial voltage Vint1 to the second node, where |Vint2|>|Vint1|.
