Abstract

See full text

A pixel drive circuit includes a data write sub-circuit, an input and read sub-circuit, a drive sub-circuit, and a first output control sub-circuit. The data write sub-circuit is configured to transmit data signals input from a first data voltage terminal at different times to a first node. The input and read sub-circuit is configured to: transmit a signal of a signal transmission terminal to a second node in a write period, and transmit an electrical signal of the second node to the signal transmission terminal in a threshold voltage read period. The drive sub-circuit is configured to output a drive signal. The first output control sub-circuit is configured to: be coupled to an element to be driven, and transmit the drive signal output by the drive sub-circuit to the element to be driven.
