Description
本发明涉及显示技术领域,特别是涉及一种显示面板的驱动电路及其驱动方法。
为了提高显示效果,往往需要对显示面板出厂前的伽马曲线和公共电压(VCOM)进行自动调试(auto Pgamma),以使每个显示面板接近标准的伽马曲线和最佳的闪烁参数,并将调试数据储存到显示面板的源驱动芯片的存储器中,之后再与驱动电路组装。
如图1所示,由于成本的因素,驱动电路中的时序控制芯片10的输入输出端口(I/O)往往复用较多功能,上电(power on)时,时序控制芯片10获取源驱动芯片的存储器中的调试数据,并将其写入到伽马芯片20中。时序控制芯片10与伽马芯片20会通过逻辑控制模块21进行通讯。
然而在上电后,时序控制芯片10自身会复位,以进行管脚的配置;由于此时时序控制芯片10会输出不确定信号给伽马芯片20,并存储至存储模块22中,从而干扰伽马芯片,使其工作异常,使得显示面板无法获得最佳的伽马(gamma)和公共电压(VCOM)参数,降低了显示效果。
