Abstract
The utility model discloses a heating device of a small-size liquid crystal display (LCD) screen. The heating device of the small-size LCD screen is characterized in that a homocentric-square-shaped film heater is arranged below the LCD screen, and a leading-wire welding plate is arranged at the position of a pin of the film heater and connected with a control unit. Due to the structure, the heating device of the small-size LCD screen has the advantages that the effect that the LCD screen can work normally under a super-low temperature environment is guaranteed; the heating device is suitable for the LCD screen with the diagonal size which is equal to or shorter than one inch; and no redundant substance interface is added to a display region of the LCD screen.
Description
Technical field
The utility model relates to the LCDs field, particularly a kind of heating arrangement of small size liquid crystal display.
Background technology
LCDs has its operating temperature range, and this is owing to liquid crystal material self-characteristic determines; Reduction along with ambient temperature, liquid crystal molecule by liquid crystal state gradually to solid-state transformation, liquid crystal molecule is lost flowability gradually, thereby lose the optically-active characteristic, cause the liquid crystal display can't operate as normal under ultra-low temperature surroundings, for military display screen, under ultra-low temperature surroundings, realize the wide temperature display characteristic of Liquid Crystal Module, improve the environmental adaptability of military hardware, just must provide heating system to liquid crystal display, to improve module low temperature display quality.
Generally, military LCD all is provided with the heating system of certain power, general surface of adopting transparent ito glass to bond to liquid crystal display as face type heater element, because liquid crystal display is relatively more responsive to temperature variation, heating power is crossed conference and the glass cracking occurred, liquid crystal liquefaction etc. influences reliability problems, the too small demand that then can't satisfy normal demonstration under the liquid crystal display ultra-low temperature surroundings of heating power.So can be according to the ito glass of the different surface resistance resistances of liquid crystal display size Selection when design ito glass well heater, because ito glass comes the chain of command resistance by control ITO coating thickness when making, the more big ITO layer of surface resistance resistance is more thin, the surface resistance resistance is crossed conference and is reduced its conduction homogeneity, and during for extra small size liquid crystal display well heater, if adopt conventional I TO glass as the face well heater, then when guaranteeing certain power supply efficiency of heating surface and surface power density, the well heater surface resistance just needs very big, and the introducing of face type well heater ito glass has reduced the whole transmitance of liquid crystal display assembly, increased module thickness and weight, this design and optimization to the warplane carrier display system has caused obstacle.
At above-mentioned problem, a kind of heating arrangement of small size liquid crystal display is provided, make that digital image source operate as normal under ultra-low temperature surroundings is the problem that prior art need solve.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of heating arrangement of small size liquid crystal display, to guarantee the purpose of LCDs operate as normal under ultra-low temperature surroundings.
For achieving the above object, the technical solution of the utility model is that a kind of heating arrangement of small size liquid crystal display is characterized in that: described heating arrangement is that the below of liquid crystal display is provided with back-shaped thin film heater; The pin place of thin film heater is provided with lead pad and is connected with control module, thereby utilizes thin film heater to replace existing ito glass, realizes the heating to liquid crystal display.
The size of described thin film heater is consistent with the housing of liquid crystal display.
The pin place of described thin film heater is provided with the temperature sensor pad, and welding and embedding have temperature sensor above.
Described thin film heater is fixed on the liquid crystal display by bond plies.
The material of described thin film heater is the PET flexible material.
A kind of heating arrangement of small size liquid crystal display, owing to adopt above-mentioned structure, advantage of the present utility model is: 1, guarantee LCDs operate as normal under ultra-low temperature surroundings; 2, be applicable to that Diagonal Dimension is the liquid crystal display of an inch and following size; 3, do not increase unnecessary material interface in the viewing area of liquid crystal display.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the structural representation of the heating arrangement of a kind of small size liquid crystal display of the utility model;
In Fig. 1,1, liquid crystal display; 2, thin film heater; 3, temperature sensor pad; 4, temperature sensor; 5, lead pad.
Embodiment
As shown in Figure 1, the utility model is that the below of liquid crystal display 1 is provided with back-shaped thin film heater 2; The pin place of thin film heater 2 is provided with lead pad 5 and is connected with control module, thereby utilizes thin film heater 2 to replace existing ito glass, realizes the heating to liquid crystal display.
The size of thin film heater 2 is consistent with the housing of liquid crystal display.The pin place of thin film heater 2 is provided with temperature sensor pad 3, is welded with temperature sensor 4 above.
The lower surface of liquid crystal display 1 is provided with back-shaped thin film heater 2, the rearward end of back-shaped thin film heater 2 is provided with temperature sensor pad 3, temperature sensor 4 welding also is potted on the temperature sensor pad three, back-shaped thin film heater 2 by bond plies be fixed on liquid crystal display 1 around.The material of back-shaped thin film heater 2 is the PET flexible material.
The back-shaped structure of thin film heater 2 of the present utility model is fixed on around the lower surface or liquid crystal display 1 of liquid crystal display 1 by bond plies, heat is from conducting to liquid crystal display 1 whole display surface by heat exchange pattern all around, and do not increase unnecessary material interface in the viewing area of liquid crystal display 1, thereby guaranteed the operate as normal of liquid crystal display 1 under ultra-low temperature surroundings, also can satisfy airborne liquid crystal display 1 ultra-low temperature surroundings conformability simultaneously.
The utility model is applicable to that Diagonal Dimension is one inch and following size, and low temperature is shown that in the higher extraordinary LCD MODULE of demand, the utility model has been used for engineering practice, and the effect performance is good.Adopt film-type four limit well heaters to replace original ito glass, adopt the back-shaped heating of PET flexible material, make when satisfying liquid crystal display low-temperature heat demand, can reduce digital image source weight and thickness, improve the whole transmitance of digital image source.
By reference to the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
