Description
技术领域
本发明属于触摸屏技术领域,具体地讲,涉及一种内嵌式电容触摸屏及其驱动方法。
背景技术
触摸屏是允许用户使用手指或者物体通过选择显示在图像显示器等的屏幕上的指令内容来输入用户的指令的输入设备。用户的手或者物体在接触位置处直接与触控面板相接触。由于这种触控面板可以代替连接到图像显示器的诸如键盘或鼠标之类的独立输入设备,所以其应用领域已经日益扩大。
内嵌式(in cell)触摸屏是将触控元件整合于显示屏内部,使显示屏具备触控功能。内嵌式触摸屏是在触控屏标准制程中即可完成触控元件的制造,不存在贴合及对位的问题,其具有更加轻薄、无需边框、可达全平面设计等诸多优点,是目前触摸屏领域内研究的热点之一。
在内嵌式触摸屏中,通常会通过对公共电极进行分时复用的方式实现内嵌式触摸功能。具体过程为:将一帧画面显示时间分为显示驱动时间和触控驱动时间;其中,在显示驱动时间内,对所有公共电极施加用于画面显示的公共电极电压;而在触控驱动时间内,对参与触控驱动的公共电极(即触控驱动电极)施加用于触控驱动的触控驱动电压,对其余未参与触控驱动的公共电极仍然施加用于画面显示的公共电极电压,从而实现画面显示和触控驱动的功能。
由于在触控驱动时间内,未参与触控驱动的公共电极上的电压为用于画面显示的公共电极电压,相应区域的画面显示正常,而参与触控驱动的公共电极上的触控驱动电压高于公共电极电压,相应区域的画面显示异常。当在连续帧显示时,每帧画面显示时间的触控驱动时间均对相应区域的公共电极施加触控驱动电压,这会造成画面显示的不均匀。同时,由于持续对同一区域的公共电极施加触控驱动电压,会造成该区域内的液晶分子老化速度加快。

参照图2,根据本发明的实施例的内嵌式电容触摸屏的驱动方法包括:
在第N帧画面显示时间T的显示驱动时间T1内向每条公共电极142和每条触控驱动电极144提供用于画面显示的公共电极电压。也就是说,在第N帧画面显示时间T的显示驱动时间T1内,每条触控驱动电极144的功能作用与每条公共电极142的功能作用完全一样,换句话说,在第N帧画面显示时间T的显示驱动时间T1内,每条触控驱动电极144均被用作为公共电极。
在第N帧画面显示时间T的触控驱动时间T2内向每条公共电极142和第2M(其中,M为整数)条触控驱动电极144提供用于画面显示的公共电极电压,并且在第N帧画面显示时间T的触控驱动时间T2内向第2M+1条触控驱动电极144提供用于触控驱动的触控驱动电压。也就是说,在第N帧画面显示时间T的触控驱动时间T2内,第2M条触控驱动电极144的功能作用与每条公共电极142的功能作用相同,而第2M+1条触控驱动电极144的功能作用与每条公共电极142的功能作用不相同。
与第N帧画面显示时间T的显示驱动时间T1一样,在第N+1帧画面显示时间T的显示驱动时间T1内向每条公共电极142和每条触控驱动电极144提供用于画面显示的公共电极电压。也就是说,在第N+1帧画面显示时间T的显示驱动时间T1内,每条触控驱动电极144的功能作用与每条公共电极142的功能作用完全一样,换句话说,在第N+1帧画面显示时间T的显示驱动时间T1内,每条触控驱动电极144均被用作为公共电极。
然而,在第N+1帧画面显示时间T的触控驱动时间T2内向每条公共电极142和第2M+1条触控驱动电极144提供用于画面显示的公共电极电压,并且在第N+1帧画面显示时间T的触控驱动时间T2内向第2M条触控驱动电极144提供用于触控驱动的触控驱动电压。也就是说,在第N+1帧画面显示时间T的触控驱动时间T2内,第2M+1条触控驱动电极144的功能作用与每条公共电极142的功能作用相同,而第2M条触控驱动电极144的功能作用与每条公共电极142的功能作用不相同。
在本实施例中,诚如背景技术中所述,用于触控驱动的触控驱动电压高于用于画面显示的公共电极电压。
综上所述,根据本发明的实施例,通过在相邻帧画面显示时间的触控驱动时间内交替向奇偶条触控驱动电极提供用于触控驱动的触控驱动电压,解决了现有技术的触控驱动时间内画面显示不均匀的问题,同时避免了触控驱动电极所对应区域内的液晶分子老化速度加快。
虽然已经参照特定实施例示出并描述了本发明,但是本领域的技术人员将理解:在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下,可在此进行形式和细节上的各种变化。
