Abstract

A display drive circuit includes first shift registers from a first shift register of a 1st-stage to a first shift register of an Nth-stage; first shift registers of first A stages are virtual shift registers which are at least configured to make that an inputted second signal of a same pixel circuit has a delay of a set time length t relative to the first signal; and first shift registers of last (N-A) stages are at least configured to provide pixel circuits with the second signal; where t=a+b+c+d; A particular drive time sequence is formed in the present disclosure, which improves the characteristics of the drive transistor, solve the display problem caused by the tailing problem of the output signal of the first shift register, and improve image display quality.
