Description

触摸显示屏的驱动方法
技术领域
说
本发明涉及显示屏驱动方法， 尤其涉及一种触摸显示屏的驱动方法。
背景技术
随着科技不断发展， 为达到更方便有效的操控， 触控面板已经广泛被整合
书
在液晶显示屏上， 形成触摸显示屏。 常见的触摸显示屏主要由显示面板、 触控 面板以及控制电路组成。
现今广泛采用的显示面板为薄膜晶体管液晶显示面板（TFT-LCD ), 图 1为 现有技术中显示面板的结构示意图。 如图 1所示， 所示显示面板 10由若千阵列 排列的像素单元组成， 对于彩色显示的显示面板 10， 像素单元可以由多个显示 不同颜色的子像素单元组成， 例如三个分別显示红绿蓝 （RGB ) 的子像素单元 11。 每一像素单元由一个 TFT (薄膜晶体管）作为驱动开关， 通常显示面板 10 通过水平向的显示扫描线 13和垂直向的数据线 12, 实现每一子像素单元 11的 显示。 控制电路包括栅极驱动电路 31 和源极驱动电路 32， 其中栅极驱动电路 31依照时序分别产生^冲式的驱动信号给显示面板 10的显示扫描线 13， 以打 开该行显示扫描线 13对应的子像素单元 11 , 打开的子像素单元 11接收源极驱 动电路 32通过数据线 12传递的数据信号， 以根据不同电压的数据信号显示相 应的灰阶。
图 2为现有技术中触控面板的结构示意图。 结合图 1和图 2, 触控面板 20 与显示面板 10相叠置设置， 触控面板 20由若干阵列排列的感测单元 21组成， 触控面板 20通过水平向的触控驱动线 23和垂直向的感应线 22， 实现对每一感 测单元 21的感测。 控制电路还包括触控驱动电路 33和感测驱动电路 34 , 其中 触控驱动电路 33依照时序分别产生脉冲式的驱动信号给触控面板 20的触控扫 描线 23，感测驱动电路 34依次对与该行触控扫描线 23连接的感应单元 21进行 检测， 以确定是否有触摸发生和触摸发生的具体位置。
为达到精确地显示效果， 显示面板 10的显示扫描线 13通常为几百条至上 千条， 例如 480条、 576条、 1024条等， 而触控面板 20的触控扫描线 23通常 为十几条至百条， 例如 100条等。 因此， 扫描过程中， 对显示面板 10的扫描时 间通常大于触控面板 20的扫描时间。
在实际触控显示过程中， 控制电路发出若干周期性的控制信号， 以驱动对 显示面板和触控面板的扫描， 图 3 为现有技术中触摸显示屏的驱动方法的时序 分配示意图。 如图 3所示， 以周期性扫描信号的频率（帧频率） 为 60Hz为例， 即每一周期 CO的时间为 16.67ms,包括两个时序一第一时序 C1和第二时序 C2， 较佳的时间分配为 C1的时间为 14.67ms， C2的时间为 2ms。在一个周期 CO内， 控制电路在第一时序 C1的时间内产生多个扫描信号依次传递给所述显示面板的 所有显示扫描线， 以完成一次对显示面板的扫描过程， 再在第二时序 C2的时间 内产生多个扫描信号依次传递给所述触控面板的触控扫描线， 以完成一次对触 控面板的扫描过程， 其后对触控面板的扫描结果进行处理分析， 进而控制下一 周期中显示面板的显示， 因而现有技术的扫描方式中， 触摸屏的扫描频率与显 示屏的扫描频率保持一致。
然而， 随着对触控面板的触控灵敏度的要求越来越高， 触摸屏的扫描频率 亟待有效提高，在 100Hz以上甚至 120Hz以上才能够达到较佳的触控响应速度， 可是显示面板的扫描频率却不能随之过度提高， 因为如杲显示面板的扫描频率 过高， 其每一条显示扫描线的扫描时间会大幅缩小， 使显示面板中每一子像素 单元的充放电时间大幅缩小， 易造成充放电时间不足， 进而影响显示面板的显 示效杲， 因此现有技术的扫描方式难以兼顾有效提高触控显示屏的灵敏度且保 持显示面板的显示效果。
