Title
(EN) Driving method, driving circuit and touch display device
(ZH) 驱动方法、驱动电路及触摸显示装置
Abstract
(EN) A driving method, a driving circuit and a touch display device are provided. The driving method includes the steps of supplying a gate driving signal to a gate line, supplying a pixel voltage to the data line, and supplying a common electrode driving signal to a common electrode, wherein pixel driving is performed based on the gate driving signal, the pixel voltage and the common electrode driving signal. Meanwhile, touch detection is carried out based on the common electrode driving signal. The driving method achieves the effect of enabling pixel display and touch detection at the same time, and solves the problem that the display of the touch display device is affected during the touch detection phase.
(ZH) 一种驱动方法、驱动电路及触摸显示装置。该驱动方法包括:将栅极驱动信号提供给栅极线,将像素电压提供给数据线,将公共电极驱动信号提供给公共电极,其中,基于该栅极驱动信号、该像素电压以及该公共电极驱动信号进行像素驱动;同时基于该公共电极驱动信号进行触摸检测。该驱动方法实现了能够同时进行像素显示以及触摸检测的效果,解决了在触摸检测阶段触摸显示装置的显示受到影响的问题。
