Side, edge frame include one side occlusion part and are connected thereto and the front occlusion part of setting at an angle, side occlusion part cover
Lid display device side, and closing structure is formed with rear shell, front occlusion part coats liquid crystal display panel periphery, and rear shell, side are blocked
Portion and front occlusion part form an accommodation space, clamping fixer crystal panel and optical module in accommodation space.The invention advantage
It is: reduces cost and complete machine ultrathin design.It is apparent that the patent relates generally to civilian LCD TV field, though have low cost
With ultra-thin advantage, but due to being not provided with heating element, the LCD MODULE is not able to satisfy under extreme low temperature environment
Normal work, thus be not particularly suited for harsh Service Environment.
The Chinese patent that number of patent application is 201520025400.8 discloses a kind of ultra-thin wide warm LCD MODULE, packet
Include the liquid crystal display panel set gradually from top to bottom, insulating heat-conductive plate, heating radiating board and insulation board；It is integrated on insulation board
Temperature sensor, heating control circuit and temperature collection circuit；After temperature collection circuit acquires the signal of the temperature sensor
To heating control circuit is transmitted to, heating control circuit control heating radiating board heats liquid crystal display panel.By setting
Setting heating radiating board and the insulation board with heat preservation, computer heating control function ensures that the temperature of liquid crystal display panel is in normal work
Make state, can guarantee normal work at -55 DEG C or less.
The Chinese patent that number of patent application is 201510037704.0 disclose a kind of liquid crystal display for low-temperature working and
Its heating means, including liquid crystal display panel, insulating heat-conductive adhesive layer, heating radiating board and the insulation board being cascading,
Heating radiating board and insulation board press fitting are integrated, and heating control circuit and temperature collection circuit are integrated on insulation board,
Temperature sampler is distributed on liquid crystal display panel, temperature sensor acquires the temperature information of the liquid crystal display panel, through temperature
Degree Acquisition Circuit is transmitted to heating control circuit to control heating radiating board work, to realize reduction/raising liquid crystal display panel
Temperature, the invention by setting heating radiating board and with heat preservation, computer heating control function insulation board ensure liquid crystal display
The temperature of panel is in normal operating conditions, can guarantee normal work at -55 DEG C or less.
It is the same LCD MODULE that can be worked normally at low ambient temperatures described in above-mentioned two patent, first should
Kind LCD MODULE is not provided with optical module, and it is impossible to meet Military Flat Panel Displays for light such as brightness, chromaticity coordinates and colour gamuts
Learn the requirement of index；Heating radiating board described in 2 two patents and insulation board are the integral structures being adhesively fixed, and are passed through
Insulating heat-conductive adhesive layer is bound with liquid crystal display, is not only difficult to maintenance of doing over again, the mode that gluing is bound after this liquid crystal display is also
A series of integrity problems such as damp and hot macula lutea can be brought；Third, the tin indium oxide or tin oxide that the heating radiating board uses are led
Conductive film is identical as the fever layer material of conventional heating glass, equally dependence foreign technology, it is expensive and be difficult to uniformly
Heating, it is necessary to which by heat-conducting plate even transition heat, thus the heating and thermal insulation module of the patent adds including one layer of heat-conducting plate, one layer
The insulation board of heat radiation plate and one layer of 1.5~2.5mm, there are also very big decline spaces for the thickness of heating and thermal insulation module；Simultaneously should
Insulation board described in patent is consistent with liquid crystal display temperature, and the specific heat capacity of general thermal insulation material is big, thus gives off from heating plate
Heat have passed through a large amount of consumption of insulation board and heat-conducting plate just arrival liquid crystal display, system heat waste is big, the heat utilization efficiency of liquid crystal display
It is low.
Therefore, one kind is explored not only to be able to satisfy wide temperature work but also there can be the ultra-thin LCD assembly compared with high display quality with reality
Now mitigate airplane spare parts weight, break the dependence to foreign technology, reduces production cost, improve the purpose of production efficiency, become
A research hotspot now.
