综上所述，本发明显示面板向触控面板提供同步信号的方法及电路，通过设置驱动电极块与感应电极块构成一电容，且驱动电极块与显示驱动芯片的同步信号输出脚之间直接用导线连接，感应电极块与触控控制芯片的同步信号输入脚之间直接用导线连接，显示驱动芯片输出同步信号后，经由该电容产生感应信号，感应信号传送至触控控制芯片并经该触控控制芯片自身的电容感应得到同步信号，不仅能够避免显示面板与触控面板之间杂讯的产生，而且相比现有技术能够减少显示面板柔性电路板与触控面板柔性电路板的引脚数，使系统端无需多考虑一根信号，降低设计的复杂度。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
