Abstract
The utility model relates to a liquid crystal display device, which comprises a display panel and at least one heater. The heater is electrically connected to the display panel, is connected with a DC power supply, and utilizes a DC voltage to heat the display panel.
Description
Technical field
The utility model relates to a kind of liquid crystal indicator (LCD), relates in particular to the liquid crystal indicator of operate as normal under a kind of cryogenic conditions.
Background technology
Along with development of science and technology, display technique is maked rapid progress, and liquid crystal indicator has also substituted traditional cathode tube ray display device gradually, has obtained widespread use in growing field.Advantage such as that liquid crystal indicator has is frivolous, little power consumption, radiation are little, thereby be widely used in the electronic equipments such as instrument and meter of notebook computer, mobile phone, digital camera, display terminal.
Because the characteristic of liquid crystal molecule itself, make that general LCD at low temperatures can't operate as normal, as display delay occurs that contrast descends, even the appearance situation that can not normally show.
The utility model content
For solving the problem of cisco unity malfunction under the prior art liquid crystal indicator low temperature, be necessary to provide the liquid crystal indicator of operate as normal under a kind of low temperature.
A kind of liquid crystal indicator, it comprises a display panel and at least one well heater, and this well heater is electrically connected to this display panel and connects direct supply, and it utilizes DC voltage to be this display panel heating.
Compared with prior art, above-mentioned liquid crystal indicator comprises this well heater, can give this display panel heating, the working temperature of this liquid crystal indicator is reached-50 ℃ to 100 ℃ super wide temperature range, and maximum operating currenbt reaches 5 amperes, and making it be heated to 0 ℃ from-40 ℃ can finish in one minute.Therefore, this liquid crystal indicator adopts well heater to be this display panel heating, thereby still can operate as normal in low temperature environment.
Description of drawings
Fig. 1 is the floor map of the utility model liquid crystal indicator one better embodiment.
Fig. 2 is the schematic cross-section of liquid crystal indicator shown in Figure 1.
Fig. 3 is the internal circuit configuration synoptic diagram of well heater shown in Figure 1.
Embodiment
Seeing also Fig. 1, is the floor map of the utility model liquid crystal indicator one better embodiment.Seeing also Fig. 2, is the schematic cross-section of liquid crystal indicator shown in Figure 1.This liquid crystal indicator 1 comprises two well heaters 20, an articulamentum 30 and a display panel 10.This display panel 10 comprises a conductive layer 11, an insulation course 12 and a glass substrate 13, and this conductive layer 11, this insulation course 12 and this glass substrate 13 are provided with from top to bottom in regular turn.These two well heaters 20 are arranged at the edge of the relative both sides of this display panel 10 respectively.This articulamentum 30 is arranged between this well heater 20 and this conductive layer 11.These two well heaters 20 are electrically connected with this conductive layer 11 by this articulamentum 30 respectively.This articulamentum 30 is to be made by conductive material, such as anisotropic conductive material.The width of this articulamentum 30 is between 1.0 millimeters to 4.0 millimeters.This well heater 20 is fixing by hot pressing mode and this display panel 10.The width of this well heater 20 is between 1.0 millimeters to 5.0 millimeters.This conductive layer 11 can have different pattern according to the demonstration demand, and it can be made by indium tin oxide.This well heater 20 is a rectangular configuration, and its two ends are extended a part from these display panel 10 edges and are connected to direct supply.
Seeing also Fig. 3, is the internal circuit configuration synoptic diagram of well heater 20 shown in Figure 1.This well heater 20 comprises a conductive part 50 and an insulation division 60.This conductive part 50 has the dressing electrode structure of symmetry, as shown in Figure 3, comprises a plurality of first parallel electrodes (indicate) and one second electrode (indicating), and this second electrode is this a plurality of first electrodes and be electrically connected with these a plurality of first electrodes vertically.The part that this conductive layer 11 is extended at these well heater 20 two ends is applied in DC voltage.The square resistance of this conductive layer 11 is between 10 ohm-100 ohm.When electric current passes through this conductive layer 11, thereby because the power attenuation of resistance makes this display panel 10 be heated, so this liquid crystal indicator 1 can operate as normal under cryogenic conditions.
Because this well heater 20 is given this conductive layer 11 heating, the working temperature of this liquid crystal indicator 1 can reach-50 ℃ to 100 ℃ super wide temperature range, and maximum operating currenbt can reach 5 amperes, and making it be heated to 0 ℃ from-40 ℃ can finish in one minute.In addition, when this well heater 20 was flexible PCB, this liquid crystal indicator 1 can be accomplished ultrathin design, can be widely used in the various flat panel display systems that need ultralow temperature work.
The utility model liquid crystal indicator can also have other change embodiments.In the change embodiment, has the angle of inclination between first electrode of the conductive part 50 of this well heater 20 and second electrode therein.In another change embodiment, the conductive part 50 of this well heater 20 has the herring-bone form electrode structure.In another change embodiment, second electrode of conductive part 50 tools of this well heater 20 has wavy shaped configuration.In another change embodiment, this liquid crystal indicator 1 can comprise one or comprise a plurality of well heaters 20.
The above only is preferred embodiment of the present utility model, not in order to restriction the utility model, all any modifications of being done within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
