Abstract
A display panel having a touch function, a display device, and a control method. The panel includes a first substrate having multiple pixel units. Each pixel unit includes a liquid crystal capacitor, a first switch, a second switch, and a first storage capacitor. A control, an input, and an output terminal of the first switch are respectively connected with a first controller, the liquid crystal capacitor, and the first storage capacitor. A control, an input, and an output terminal of the second switch are respectively connected with a signal controller, a common electrode, and the liquid crystal capacitor and the first storage capacitor. When a picture change rate is lower than a preset rate value, a turn-off time of the second switch is increased, and the first switch is turned on to increase the quantity of electric charge for maintaining a voltage of the liquid crystal capacitor.
