Description
Technical field
The present invention relates to field of display devices, relate in particular to a kind of display device of exhaust defrosting function.
Background technology
Shown in Fig. 1, in the application of liquid crystal display, generally in the inside of housing 1a, display panel 2a is set at present, on display panel 2a, can form image, utilize backlight module (not shown) throw light, image is seen through to housing 1a leading flank and appear, watch for user.In order to protect display panel 2a and to maintain the leakproofness of housing 1a; opening 11a place can cover the strengthening glass sheets 3a of layer of transparent; with protection display panel, 2a is not damaged, and because of assembling reason, between this strengthening glass sheets 3a and this display panel 2a, can be formed with clearance 31a.Or arrange with the alternative strengthening glass sheets 3a of contact panel, except protection display panel 2a, also can see through contact panel and directly click the shown diagram of display panel 2a, operate.But for electronic installation, moisture tends to cause serious infringement, for example, make circuit be short-circuited or cause the corrosion of electronic component.Although the housing 1a of electronic installation can avoid moisture directly to invade, still cannot keep out the penetrating of water vapor of outside gaseous state.In the time of these water vapor contact strengthening glass sheets 3a, due to the easy heat conduction of material of strengthening glass sheets 3a, make the temperature of strengthening glass sheets 3a medial surface can extremely approach the temperature of housing 1a outside, make the water vapor of the inner high-vapor-pressure of housing 1a in the time of contact low-temperature reinforcement glass plate, there is condensation, form fine liquid particles, form fog at the medial surface of strengthening glass sheets 3a.This fog is except causing strengthening glass sheets 3a to become opaque, and the image fog that display panel 2a is produced is unclear, and the concentrated large quantity of moisture that condenses for a long time also damages in the electronic component in possibility infiltrate crystal display.For the demist of strengthening glass sheets 3a, common way has type of heating, and around strengthening glass sheets 3a or medial surface attaches superfine heating wire, to strengthening glass sheets, 3a heats, and promotes the temperature of medial surface, makes water vapor be difficult for condensation.But for portable electronic devices, its size design is towards compact, and inner space is limited, be difficult for extra heating wire and the needed circuit of driving heating wire of increasing.And portable electronic devices is with battery-operated, high to low power consumption requirement, use heating wire to increase power consumption, and do not meet the demand of portable electronic devices.Also have for strengthening glass sheets 3a and carry out plated film or gloomy as chemical agent, change the interface characteristic on strengthening glass sheets 3a surface, make water vapor be difficult for condensing.But plated film or to infiltrate chemical agent Expenses Cost higher, and it can only delay water vapor rate of setting, after long-time operation, still can build up moisture, cannot thoroughly remove fog.
In sum, the front of the display panel of electronic installation must add transparent panel, and so that display panel is protected, but the fractal one-tenth fog of the easy condensate water of transparent panel medial surface affects sight line, and the moisture excessively condensing also can cause the infringement of inner member.
Therefore, be necessary to design a kind of novel display device, to overcome above-mentioned defect.
