Abstract
The utility model discloses a liquid crystal display which comprises a liquid crystal screen, heating glass/a heating film and silica gel clamped between the liquid crystal screen and the heating glass/the heating film. The silica gel is good in heat conduction, so that the liquid crystal display is high in heating efficiency, simple in technique and lower in cost. Besides the liquid crystal display is filled with the high-light-transmission silica gel, and the display effect is not affected basically.
Description
Technical field
The utility model relates to a kind of LCD, especially a kind of LCD that is applicable to cryogenic conditions.
Background technology
The liquid crystal material of LCDs is subjected to low temperature effect bigger.Low temperature directly influences response time and the threshold voltage of liquid crystal, general LCD, and when environment temperature is brought down below below 0 ℃, the liquid crystal material viscous that will become, response speed is slack-off, and conditions of streaking appears in dynamic image, even can't show.Therefore, can in design, must consider the LCDs heating problems at industry or the military reinforcing display of operate as normal under the low temperature environment to needs.
The low-temperature heating method of available liquid crystal display generally has following several: 1, place heating glass (heating film) and heat before LCD screen; 2, take liquid crystal panel apart, after liquid-crystalline glasses is close in even tabula rasa front, put into the heating film heating; 3, whole heating namely adopts resistance wire or other heater elements that display is carried out the integral body heating in the display screen enclosure interior.But all there are some shortcomings in above-mentioned three kinds of heating means, and method 1 is owing to reason on the liquid crystal panel structure, in fact heating glass can't be close to the LCD screen surface, has certain interval, so heating glass can only heat liquid crystal display by radiation, the efficiency of heating surface is low, and heat time heating time is long; Method 2 need be taken liquid crystal panel apart, and the original structure of counter plate transforms, complex process, difficulty is big, and since heating film put into the change that can cause display color; Method 3 because heating source and liquid crystal display distance are far away, produce heat and mostly is dispersed into outside display by housing, and the efficiency of heating surface is very low, and power is big, generally needs very long heat time heating time.
So, need a kind of new technical scheme to address the above problem.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of technology simple, the LCD that the efficiency of heating surface is high.
For achieving the above object, the utility model LCD can adopt following technical scheme:
A kind of LCD, comprise liquid crystal display, heating glass/film and be sandwiched in liquid crystal display and heating glass/film between the silicon gel.
Compare with background technology, the utility model efficiency of heating surface height, technology are simple, and cost is lower; And the silicon of high printing opacity is gel-filled, and display effect is not had influence substantially.
Description of drawings
Fig. 1 is the structural representation of the utility model LCD.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
See also shown in Figure 1ly, the utility model discloses a kind of LCD, comprise liquid crystal display 1, heating glass/film 2 and be sandwiched in liquid crystal display 1 and heating glass/film 2 between the silicon gel 3 with the high heat conduction characteristics of high printing opacity.Have the characteristics of the high heat conduction of high printing opacity by silicon gel 3, the heat that heating glass/film 2 heating backs produce is directly conducted on the LCD screen by the silicon gel.This LCD adopts the advantage of filling the mode of silicon gel 3 between liquid crystal display 1 and the heating glass/film 2 to be: 1, efficiency of heating surface height, improve more than 50% than the simple employing heating glass thermal efficiency; 2, need not dismantle the liquid crystal panel original structure, technology is simple, and cost is lower; 3, the silicon of high printing opacity is gel-filled, and display effect is not had influence substantially.
Described heating glass/film 2 can also further have the function of electromagnetic screen, and the outside surface plating that concrete scheme is described heating glass/film 2 has the shielding material layer, perhaps is provided with wire gauze in described heating glass/film 2.Thereby liquid crystal display 1 is carried out the electromagnetic screen protection.
Claims (3)
1. LCD is characterized in that: comprise liquid crystal display, heating glass/film and be sandwiched in liquid crystal display and heating glass/film between the silicon gel.
2. LCD according to claim 1, it is characterized in that: the outside surface plating of described heating glass/film has the shielding material layer.
3. LCD according to claim 1 is characterized in that: be provided with wire gauze in described heating glass/film.
