Abstract

The invention provides a display panel and a display device. The display panel comprises a display area and a non-display area located on the periphery of the display area. The display panel comprises: a substrate; first signal lines which are located on one side of the substrate, extend in the first direction and are arranged in the second direction, wherein the first direction intersects with the second direction; a plurality of heating electrodes which are located on one side of the substrate and located in the display area; and a first driving chip which is located in the non-display area and electrically connected with the multiple first signal lines. The display area comprises a first display area and a second display area, and the second display area is located between the first display area and the first driving chip; and the distribution density of the heating electrodes in the second display area is smaller than that of the heating electrodes in the first display area. The invention provides a display panel and a display device, and aims to solve the problem of poor display of the display panel in a low-temperature state, balance the temperature in each region and improve the temperature uniformity of the display panel.

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] Because it is often required to be in a special working environment, the liquid crystal display device for military or vehicle display is required to be able to adapt to a wide range of ambient temperature, and sometimes it is even required to work normally within the temperature range of -20°C to 55°C. However, because the viscosity coefficient of the liquid crystal material increases at low temperature, the threshold voltage increases, the response speed becomes slow, and even the phenomenon of liquid crystal crystallization occurs, so that the liquid crystal display device cannot work normally. Taking Sharp's wide temperature liquid crystal display device as an example, the normal low temperature operating point of the normal temperature type device is -5°C, and the low temperature normal operati...
