Abstract: A touch panel and a display device are provided according to the disclosure. The touch panel includes a common electrode and multiple pixel electrodes, and each of the pixel electrodes is short-circuited to the common electrode when the touch panel is powered off. Thus, there is no potential difference between the pixel electrode in each pixel unit and the common electrode, and there is no residual charge between the pixel electrode and the common electrode, after the touch panel is powered off. Therefore, liquid crystal molecules may be twisted in the case that the touch panel is powered off, impurity ions inside the liquid crystal molecules may not be polarized, and may not be attached to an upper substrate and a lower substrate of a touch panel in a long term.
Abstract translation: 根据本公开提供了触摸面板和显示装置。 触摸面板包括公共电极和多个像素电极，并且当触摸面板断电时，每个像素电极与公共电极短路。 因此，在触摸面板断电之后，像素单元中的像素电极和公共电极之间没有电位差，并且在像素电极和公共电极之间不存在剩余电荷。 因此，在触摸面板断电的情况下，液晶分子可能被扭曲，液晶分子内的杂质离子可能不被偏振，并且可能不会附着到触摸面板的上基板和下基板 长期。
