Abstract
The disclosure discloses a GOA circuit based on the LTPS, including a modulation circuit; a charging circuit; an input signal terminal and an output signal terminal. The modulation circuit and the charging circuit are connected to the input signal terminal and the output signal terminal to make the modulation circuit and the charging circuit in parallel connection, and the charging circuit is used to charge the output scanning signal during the mutation process to increase the mutation speed of the output scanning signal. Wherein the charging circuit is a switch including a control terminal, a first terminal, and a second terminal; the input signal terminal is connected to the first terminal of the charging circuit. The output signal terminal is connected to the second terminal and the control terminal of the charging circuit separately. A display apparatus including the GOA circuit based on the LTPS is also provided.
