Abstract

Embodiments of the present invention provide a display panel and a display device. The display panel includes: a common electrode, a heating electrode, a common voltage terminal, a power supply terminal and a switch; the common electrode is electrically connected to the common voltage terminal; the power supply terminal includes a first heating power supply terminal and a second heating power supply terminal; the heating electrode includes a first end and the second end, the first end of the heating electrode is electrically connected with the first heating power terminal; the switch includes a first state and a second state; in the first state, the second heating power terminal is connected to the second heating electrode through the switch. The terminal is electrically connected; in the second state, the second heating power supply terminal is electrically connected with the common electrode through the switch. When applied in a high temperature environment, the second heating power supply terminal and the common power supply terminal simultaneously provide a voltage signal to the common electrode, so as to reduce the deviation between the actual voltage value on the common electrode and the preset optimum value, and improve the flickering under high temperature. and afterimage phenomenon.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Liquid crystal display technology has been widely used in display devices such as mobile phones, computers, televisions, and vehicle-mounted displays. However, the characteristics of liquid crystal materials at different temperatures will be different. For example, at low temperatures (eg, below 0° C.), the viscosity coefficient increases, resulting in a slower response speed, which affects the normal operation of the display device. In order to ensure that the display device can still display normally in a low temperature environment, a solution of setting heating electrodes in the display device is adopted, and the heating electrodes are used to heat the liquid crystal molecules at low temperature, so as to improve the response speed of the liquid crystal molecules. In fact, for display devices w...
