Embodiment 1
[0032] This embodiment provides a liquid crystal display panel, including: an array substrate and a color filter substrate, and a liquid crystal layer arranged between them; the color filter substrate includes a light-transmitting area and a non-light-transmitting area; / or a transparent heating element is provided in the non-transparent area; and / or a non-transparent heating element is provided in the non-transparent area.
[0033] In the liquid crystal display panel of the present invention, since a heating element is arranged inside the liquid crystal display panel, especially on the color filter substrate close to the liquid crystal layer, the heating element can quickly display the liquid crystal display panel at a low temperature; at the same time, compared with the external heating The method has the advantages of low power consumption and fast heating.
[0034] Specifically, as figure 1 As shown, the color filter substrate of the liquid crystal display panel includes ...
Embodiment 2
[0044] This embodiment provides a liquid crystal display panel. The difference from Embodiment 1 is that the above-mentioned heating element is a transparent heating element 21; preferably, the above-mentioned transparent heating element 21 is made of transparent metal and alloy, for example, indium tin oxide (ITO) make.
[0045] The above-mentioned transparent heating element can adopt the same structure as that in the embodiment.
[0046] In addition, since the heating element is a transparent heating element 21, the transparent heating element 21 can be arranged in a more flexible manner, for example, as Figure 5 As shown, the transparent heating element 21 can be arranged in the whole layer; the transparent heating element 21 can also be partially arranged in the light-transmitting area, etc., which will not be repeated here.
Embodiment 3
[0048] Such as Figure 6 As shown, this embodiment provides a temperature control system for a liquid crystal display panel, including: a temperature sensor for detecting the temperature of the liquid crystal display panel; the temperature sensor can be set in the driving area of the liquid crystal display panel to avoid affecting the display of the pixel unit, It should be understood that if a sufficiently small temperature sensor is used, the temperature sensor can also be set in the area corresponding to the black matrix to test the temperature of the liquid crystal cell at a closer distance;
[0049]The controller is used to receive the temperature signal sent by the temperature sensor and judge whether to supply power to the non-transparent heating element or the transparent heating element of the liquid crystal display panel; the temperature sensor of the controller is electrically connected to exchange signals with the temperature sensor; if the temperature of the liqu...
