A panel driving circuit comprises switch tubes T1, T2, T3 and T4 and a capacitor, a grid electrode of the T1 is connected with an upper-stage driving signal, and a drain electrode of the T1 is connected with a grid electrode of the T4, one end of the capacitor and a source electrode of the T2; the drain electrode of the T4 is connected with the other end of the capacitor and the source electrode of the T3; the drain electrode of the T4 is also connected with a current-stage driving signal; and the grid electrodes of the T2 and the T3 are connected with a next-stage driving signal, and the drain electrode of the T2 is connected with the drain electrode of the T3. By reducing the number of the TFTs, the requirement of a narrow frame of the panel is met, and the design difficulty is reduced. 一种面板驱动电路，包括开关管T1、T2、T3、T4、电容，所述T1的栅极与上一级驱动信号连接，漏极与T4的栅极、电容的一端、T2的源极连接；所述T4的漏极与电容的另一端、T3的源极连接，T4的漏极还与当前级驱动信号连接；所述T2和T3的栅极与下一级驱动信号连接，所述T2的漏极与T3的漏极连接。本实用新型通过减少TFT数量从而实现面板窄边框的需求以及减轻设计难度。
