The utility model discloses a mobile phone screen capable of working at ultra-low temperature, which adopts the technical scheme that a heating plate is arranged between the LED backlight source and the liquid crystal display of a common mobile phone screen. The heating plate adopts a glass plate with transparent conductive film; and a conductive flexible printed circuit FPC is bonded on the glass plate with transparent conductive film, the glass plate with transparent conductive film is assembled in an LED backlight groove, and the flexible printed circuit FPC on the glass plate with transparent conductive film is welded with the flexible printed circuit FPC on the liquid crystal display. The mobile phone screen provided by the utility model can automatically heat the liquid crystal display and a large-scale control circuit through the intelligent control circuit of a mobile phone when the temperature is below minus 30 DEG C, so that the temperature of the whole display device is kept above minus 30 DEG C. Therefore, the mobile phone screen can normally work and be applied in extremely cold areas such as the Arctic Pole, the Antarctic Pole and the like.
Description
Technical field
The utility model relates to a kind of mobile phone screen, but relates in particular to a kind of mobile phone screen of ultralow temperature work.
Background technology
Present applied mobile phone screen is by LCDs, the LED-backlit source, and flexible circuit board (FPC), extensive control circuit is formed.But because the characteristic of liquid crystal, liquid crystal can freeze at low temperatures, and thereby extensive control circuit effect also out of hand at low temperatures causes the mobile phone screen can not show problems such as any literal and figure at low temperatures, present known mobile phone screen working temperature is between-30 to 80 degree, so general mobile phone screen can not be in the arctic, low temp area work such as the South Pole, this give some in the arctic or the personnel of some low temp area work of the South Pole cause inconvenience in some communications.
Summary of the invention
The purpose of this utility model is: can not be in the problem of low temp area work in order to overcome existing mobile phone screen, on common mobile phone screen, provide a kind of heating plate, this heating plate is lower than in temperature under-30 degree and can heats to LCDs, extensive control circuit automatically, whole display device temperature is controlled at more than-30 degree, thereby makes mobile phone screen energy operate as normal.
The purpose of this utility model realizes by following scheme: be provided with heating plate between the LED-backlit source of common mobile phone screen and LCD.Described heating plate is the glass plate of band transparent conductive film.
Bound conductive flexible wiring board (FPC) on the band transparent conductive film glass plate described in the utility model.
Band transparent conductive film glass plate described in the utility model is assembled in the LED-backlit groove, and the flexible circuit board on the transparent conductive film glass plate (FPC) is welded on the flexible circuit board (FPC) of liquid crystal hand display.
The glass plate of the utility model transparent conductive film (ITO) is composited by transparent conductive film (ITO) and glass substrate, the FPC, the parallel pole that also comprise the glass plate of transparent conductive film (ITO), the pin of the FPC of the glass plate of transparent conductive film (ITO) is drawn the anode and the negative electrode of the glass plate of transparent conductive film (ITO), the electrically conducting transparent thin surface is connected with the surface of glass substrate, another surface of parallel pole 5 and transparent conductive film is connected, and the FPC pin of the glass plate of transparent conductive film (ITO) is connected with parallel pole.
The glass substrate of the glass plate of the utility model transparent conductive film (ITO) uses high impedance, high permeability, ultra-thinization glass baseplate.
The utility model is lower than in temperature under-30 degree and can heats to LCDs, extensive control circuit automatically, whole display device temperature is controlled at more than-30 degree, thereby make mobile phone screen energy operate as normal, be useful in the extreme cold area as the arctic, low temp areas such as the South Pole.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to Fig. 1,2, the utility model comprises LED-backlit source 1, heating plate, the FPC of LCDs 3 and LCDs 3, between LED-backlit source 1 and LCDs 3, clamp heating plate, heating plate is the glass plate 2 of transparent conductive film (ITO) and is assembled in the LED-backlit groove, the glass plate 2 of transparent conductive film (ITO) is composited by transparent conductive film (ITO) 7 and glass substrate 6, the FPC that also comprises the glass plate 2 of transparent conductive film (ITO), parallel pole 5, the pin 4 of the FPC of the glass plate 2 of transparent conductive film (ITO) is drawn the anode and the negative electrode of the glass plate 2 of transparent conductive film (ITO), thin 7 surfaces of electrically conducting transparent are connected with the surface of glass substrate 6, parallel pole 5 is connected with transparent conductive film 7 another surfaces, and the FPC pin 4 of the glass plate 2 of transparent conductive film (ITO) is connected with parallel pole 5; The glass substrate 6 of the glass plate 2 of transparent conductive film (ITO) uses high impedance, high permeability, ultra-thinization glass baseplate, just because of employed high permeability, ultra-thinization glass baseplate, so the mobile phone screen still can be accomplished ultra-thinization, minimal thickness is 2.0mm, is can accomplish the same in brightness with thickness no matter compare normal mobile phone screen.The FPC pin of the glass plate 2 of LED-backlit source 1 and transparent conductive film (ITO) is welded on the FPC of LCDs 3, and last then FPC by LCDs 3 is connected on the cell phone mainboard.
Design the automatic temperature-adjusting control circuit on cell phone mainboard, when temperature is lower than-30 when spending, temperature-control circuit can start heating plate and carry out work, the heating plate heating, thus the temperature of mobile phone screen can be maintained more than-30 degree.The glass plate 2 of transparent conductive film (ITO) be by with rated current mode drive, when the cell phone mainboard temperature-control circuit is being lower than-30 when spending, temperature-control circuit is opened automatically, and the glass plate 2 to transparent conductive film (ITO) makes its heating with rated current and keeps mobile phone screen body temperature to be not less than the temperature that liquid crystal display requires then.
