Abstract

A touch control display panel and a display method and a display device therefor, the display method comprising: when a touch control display panel is in a display stage, a common electrode (705) drives a pixel electrode (704) by means of a first direct current voltage; it is detected whether the amount of electric charge accumulated on one side corresponding to the common electrode (705) exceeds a preset threshold; and if yes, the common electrode (705) drives the touch control display panel by means of a second direct current voltage in the next display stage, wherein the amount of electric charge generated by the difference value between the second direct current voltage and the first direct current voltage in the display stage is the same as that accumulated by the common electrode (705), and the polarity is opposite. By means of the described display method, residual images of a liquid crystal display device may be eliminated, and the display quality may be improved.

Description

technical field [0001] The present invention relates to the field of terminal display, in particular to a touch display panel, a display method, and a display device. Background technique [0002] Afterimage is a common phenomenon of poor display of the touch display panel, and it is also a very important test link in the reliability test. Generally, afterimages can be divided into long-term afterimages and short-term afterimages, and the physical mechanisms of their occurrence are also different. The more common one is long-term afterimages. Long-term afterimages are caused by DC sticking. [0003] During the manufacturing process of liquid crystals, due to changes in the process environment and conditions, the liquid crystal molecules cannot be completely purified, resulting in some mobile ions remaining in the liquid crystal molecules. When a voltage is applied, these mobile ions will move towards a certain electrode under the action of an external electric field until ...
