本发明实施例通过设置两个显示区域(第一显示区域和第二显示区域) 同时驱动阵列基板上的像素阵列, 提高阵列基板图像显示的刷新率。 具体地, 逐行开启该电路中第一显示区域的第一组栅极扫描线, 逐行开启该电路中第 二显示区域的第二组栅极扫描线, 在开启第一显示区域中所述第一组栅极扫 描线中的某一条栅极扫描线时, 也同时开启第二显示区域中所述第二组栅极 扫描线中的一条栅极扫描线, 也就是说, 在同一时刻同时开启阵列基板上的 两条不同栅极扫描线, 这两条栅极扫描线分别与两个不同的源极驱动电路连 接, 当两条栅极扫描线开启时, 两个源极驱动电路分别输入各条数据信号线 对应的数据信号, 实现图像显示。 由上可知, 在与现有扫描信号脉沖宽度相 同的情况下, 阵列基板显示图像的刷新率至少为原来的二倍。  The embodiment of the invention improves the refresh rate of the image display of the array substrate by setting two display regions (the first display region and the second display region) to simultaneously drive the pixel array on the array substrate. Specifically, the first group of gate scan lines of the first display area in the circuit are turned on line by line, and the second group of gate scan lines of the second display area in the circuit are turned on line by line, and the first display area is turned on in the first display area.
