现有市场上的液晶显示装置大部分为背光型液晶显示装置,其包括液晶显示面板及背光模组(backlight module)。液晶显示面板的工作原理是在薄膜晶体管阵列基板(Thin Film Transistor Array Substrate,TFT Array Substrate)与彩色滤光片(Color Filter,CF)基板之间灌入液晶分子,并在两片基板上施加驱动电压来控制液晶分子的旋转方向,以将背光模组的光线折射出来产生画面。
OLED显示装置通常采用氧化铟锡(ITO)像素电极和金属电极分别作为器件的阳极和阴极,在一定电压驱动下,电子和空穴分别从阴极和阳极注入到电子传输层和空穴传输层,电子和空穴分别经过电子传输层和空穴传输层迁移到发光层,并在发光层中相遇,形成激子并使发光分子激发,后者经过辐射弛豫而发出可见光。

需要说明的是,本发明的触控显示装置的驱动方法利用控制模块 30 通过侦测线 40 对感应电极层 21 上的电压进行侦测,从而监控感应电极层 21 的电压的波形状态,当侦测到感应电极层 21 上的电压的波形出现波纹时,控制模块 30 直接对显示面板 10 的多条数据线 11 所输入的数据电压的极性进行翻转,通过这种方式,能够使得感应电极层 21 的电压的波形的波纹立即消失,以显示 Dot V Strip 画面为例,请参阅图 6 ,本发明中感应电极层 21 上的电压的波形相比于图 3 中现有技术的感应电极层上的电压波形,波纹被有效地去除,因此相比于现有技术,本发明的触控显示装置能够有效的消除感应电极层 21 的电压波形的异常波纹,避免异常波纹影响感应电极层 21 对感应信号的接收,保证了触控功能正常实现,提升了产品的品质,解决了触控显示装置中的信号干扰问题。
综上所述,本发明的触控显示装置包括显示面板、触控层及控制模块,显示面板包括多条间隔设置的数据线,触控层包括感应电极层,控制模块经侦测信号线与感应电极层电性连接,驱动时,利用控制模块通过侦测信号线对感应电极层上的电压进行侦测,当控制模块侦测到感应电极层上的电压的波形出现波纹时,控制模块对显示面板的多条数据线所输入的数据电压的极性进行翻转,能够有效消除感应电极层上感测信号的异常波纹,可靠地实现触控功能。本发明的触控显示装置的驱动方法能够消除感应电极层上感测信号的异常波纹,使得触控显示装置能够可靠地实现触控功能。
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。
