Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment that obtains, and all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of display device, comprises liquid crystal panel 1 and the backlight module 2 that is arranged at liquid crystal panel 1 one sides.Liquid crystal panel 1 is become box-like with color membrane substrates by array base palte, and this display device also comprises: heating component 3 and control module (not shown), heating component 3 can be arranged at the side of liquid crystal panel 1 away from backlight module 2, as shown in Figure 2; Heating component 3 also can be arranged at the side of liquid crystal panel 1 near backlight module 2, namely between liquid crystal panel 1 and backlight module 2; Heating component 3 comprises the heating plate 31 of covering liquid crystal panel 1, and heating plate 31 is transparent conductor, is provided with two electrodes 32 on heating plate 31; Control module is electrically connected on heating plate 31 by two electrodes 32.Electrode 32 can adopt the material that tensile strength is high, high temperature resistant and weldability is good.Owing to being provided with the PCB circuit board in liquid crystal panel, therefore above-mentioned control module can be arranged on this PCB circuit board, to save space
Particularly, thereby control module makes heating plate 31 energising heatings by two electrodes 32, and can control the heating-up temperature of heating plate 31.
The utility model embodiment, arrange heating component by the side at liquid crystal panel, realizes the heating to liquid crystal panel, improved the display quality of liquid crystal display under low temperature environment.
Particularly, above-mentioned heating plate 31 can be electro-conductive glass, is specifically as follows at the ultrathin of high permeability tin indium oxide (Indium Tin Oxide, the ITO) layer that is coated with on glass.
As shown in Figure 3 and Figure 4, further, heating component 3 also comprises around heating plate 31 heating wires 33 on every side, between heating wires 33 and heating plate 31, insulation arranges, for example heating wires 33 is bonded on heating plate 31 by silica gel, wherein silica gel plays the effect of insulation, and the two ends of heating wires 33 are electrically connected on control module 4.Heating wires 33 can by various coiling modes be centered around heating plate 31 around, for example, heating wires be woven into after wire be centered around uniformly heating plate around, perhaps heating wires is carried out folding for several times densely covered processing in the position at four angles of heating plate, makes the heating effect at four jiaos of places of liquid crystal panel better.
Independent heating plate transmits the heat that distributes to space can exist larger difference, this difference under the low-temperature working state, can cause the temperature of display panels uneven, and namely the surrounding temperature of LCDs is lower, medium temperature is higher, make the display effect variation, be specially, LCDs periphery response speed is slower, and when black state, normal in the middle of LCDs, but edge especially four jiaos can turn white or turn blue, obvious aberration, appear in poor contrast.Thereby control module 4 makes heating wires 33 energising heatings, and can control the heating-up temperature of heating wires 33.The heating wires 33 that is arranged at heating plate 31 peripheries can further improve the heat of liquid crystal panel periphery, thereby has improved the temperature homogeneity of liquid crystal panel, has avoided the poor problem of display effect that causes due to liquid crystal panel temperature inequality.
