摘要:
A GOA circuit, a driving method thereof and a display apparatus are provided, the GOA circuit comprising: a drive line scan control signal generation unit operative to generate a drive line scan clock signal and a drive line scan pulse signal; multiple GOA groups (102) operative to acquire the drive line scan clock signal, to generate GOA group (102) output signals sequentially according to GOA group (102) input signals, wherein the GOA group (102) output signal generated by one of the GOA groups (102) is the GOA group (102) input signal of a next GOA group (102) so as to realize a shift register function of the multiple GOA groups (102); multiple drive line scan signal generation modules (103) operative to acquire the GOA group (102) output signals and the drive line scan pulse signal, and to generate drive line scan signals sequentially; multiple gate line groups (104) operative to be applied with the drive line scan signals, so as to complete drive line scan for the multiple gate line groups (104) sequentially. The above circuit has both the display and the touch scan function, thereby the chip area, the cost and the area of the peripheral wirings can be decreased.
