Problems solved by technology
Therefore, it is also required that each liquid crystal display device must be used and stored within the temperature range between Ts-TL. If the use or storage temperature is too low, the crystallization will destroy the alignment layer of the liquid crystal display device and affect the display quality of the LCD; and the temperature is too high. High, the liquid crystal will lose the liquid crystal state, and also lose the function of the liquid crystal display device
For liquid crystal displays used in cold or hot areas, it is very easy to cause malfunction or poor display quality due to high or low operating temperature

The invention discloses an LCD working temperature adjusting system which comprises a sealing part,a change-over valve, a heating device, a refrigerating device, a controller, a pump and a temperature sensor. The sealing part is connected with the periphery of an LCD protecting body and matched with the protecting body to form a sealed cavity. Two polarizers are located in the sealed cavity. The sealed cavity is communicated with the change-over valve. The change-over valve is connected with the heating device and the refrigerating device and forms an adjusting loop. The pump is installed on a pipeline for communicating the sealed cavity with the change-over valve. According to the working states of the change-over valve and the pump, the adjusting loop has the different loop states. The controller is electrically connected with the change-over valve, the refrigerating device, the heating device, the pump and the temperature sensor. The temperature sensor is used for detecting the temperature inside the sealed cavity. The controller controls the adjusting loop according to the temperature value detected by the temperature sensor. The LCD working temperature can be effectively adjusted, and the LCD displaying quality is improved.
Description
technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to an LCD liquid crystal display operating temperature adjustment system. Background technique [0002] With continuous breakthroughs in key technologies of liquid crystal screens and continuous decline in prices, liquid crystal displays (LCD, Liquid Crystal Display) have been widely used in electrical equipment such as televisions, computer monitors, and flat panels. [0003] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an LCD liquid crystal display in the prior art. The existing liquid crystal display includes two polarizers 1, two layers of glass substrates 2, the two glass substrates 2 are installed between the two polarizers, liquid crystals, light filters, thin film transistors, etc. Both are arranged between two layers of glass substrates 2 . In order to prevent the outer polarizer from being scratched, a protective body 4 is u...
