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...

Abstract

The invention provides a liquid crystal display panel, a temperature control system thereof and a liquid crystal display device, belongs to the technical field of display and solves the problem that the existing liquid crystal display panel and liquid crystal display device can not fast display at a low temperature. According to the liquid crystal display panel, the temperature control system thereof and the liquid crystal display device, as a heating element is arranged in the liquid crystal display panel, particularly at a colorful film substrate close to a liquid crystal layer, and the liquid crystal display panel can fast display at the low temperature due to the heating element; meanwhile, the liquid crystal panel has the advantages of lower power consumption and fast heating speed compared with an outer hanging heating mode.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a liquid crystal display panel, a temperature control system thereof, and a liquid crystal display device. Background technique [0002] As one of the main ways to finally obtain information in the process of human-computer interaction, the display is an important device of information equipment. In the battle command, weapon control, and information processing systems of the battlefield, the armed forces, whether it is a large fixed facility, a moving machine or a portable instrument, a display must be configured to provide users with various information. For example, in the cockpit of an aircraft, the pilot obtains a lot of information about the over-the-horizon tactical situation, the status of the aircraft, the fire control status, and navigation through the display. [0003] Liquid crystal display is the most important type of display, and its inherent characte...
