Abstract

The present invention provides a liquid crystal display panel and a liquid crystal display device, wherein the liquid crystal display panel includes a first substrate, a second substrate, and a liquid crystal layer located between the first substrate and the second substrate, The liquid crystal display panel also includes a heating electrode, which is located inside the liquid crystal display panel, so that the heat generated by it can directly act on the liquid crystal molecules in the liquid crystal layer, so as to achieve the purpose of quick start of the liquid crystal display panel in a low temperature environment. The display panel is provided with a dummy electrode formed on the same layer as the heating electrode. By using the dummy electrode to replace part of the heating electrode in some areas, the heat distribution in the entire liquid crystal display panel can be adjusted while achieving design uniformity, preventing liquid crystal display The local temperature of the panel is too high and the display effect is affected.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a liquid crystal 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 temperatures, and sometimes it is even required to work normally within the temperature range of -20°C to 55°C. However, due to the increase of the viscosity coefficient of the liquid crystal material 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. Take Sharp’s wide-temperature liquid crystal display device as an example. The normal temperature-type device’s low-temperature normal operating point is -5°C, and the wide-temperatu...
