一种基于LTPS的GOA电路及显示面板
摘要：
本发明公开一种基于LTPS的GOA电路，包括：调制电路，充电电路，输入信号端、输出信号端，输出信号端输出扫描信号。调制电路及充电电路均连接输入信号端和输出信号端，使得调制电路及充电电路为并联连接关系，充电电路用于在扫描信号突变过程中对其进行充电，加快扫描信号的突变速度。其中，充电电路是一开关，包括控制端、第一端、第二端。输入信号端连接充电电路的第一端。输出信号端分别连接充电电路的第二端及控制端。本发明还提供一种显示面板，包括基板及基板上的如前所述的基于LTPS的GOA电路。本发明通过充电电路进行辅助充电或电荷泄放，降低扫描信号的下降或上升时间，提高GOA电路工作的稳定性。
摘要（英）：

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.
