Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display modules, in particular to a low-temperature resistant liquid crystal display module. Background Art

[0002] Display screens are mainly divided into two categories: CRT display screens (image tube displays) and LCD display screens (liquid crystal displays). Among them, LCD display screens are mainly used as a type of display for digital clocks and many portable computers. Liquid crystal display (LCD) technology information products are all developing towards the goal of being light, thin, short and small, and display products with a long history in computer peripherals are of course no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT image tube displays and LED display panels are all restricted by factors such as large size or huge power consumption, and cannot meet the actual needs of users. The development of LCD display technology just fits the trend of information products. Whether it is right-angle display, low power consumption, small size, or zero radiation, it can allow users to enjoy the best visual environment.

The utility model can lock the back cover on the frame through the cooperation of structures such as the card block, the card slot, the spring and the card column, and the lock can be released by pressing the card column, so as to separate the back cover from the frame, thereby realizing rapid disassembly and assembly between the back cover and the frame, facilitating timely maintenance when the components are damaged, and greatly improving work efficiency, but it does not solve the problem of how to reduce temperature loss and the transmission of external low temperature to the interior: for this reason, we propose a low-temperature resistant liquid crystal display module.
