Abstract
The utility mode provides a liquid crystal display module which can normally work under the ultra low temperature. The liquid crystal display module comprises a printed circuit board 10, an LED back light source 20 and a liquid crystal display 30, and is characterized in that a heating element 40 is arranged between the LED back light source 20 and the liquid crystal display 30, the heating element is a glass plate with a transparent conducting thin film, an electrode 41 is installed on the edge of the short sides of the glass plate, and the electrode 41 is inserted in an inserting hole 11 of the edge of the tow sides of the printed circuit board 10. Because a heating element is added, the utility model enables the display module to be normally used under the ultra low temperature of negative 50 DEG C.
Description
Technical field
The utility model relates to LCD MODULE, particularly relate to a kind of can be under the ultralow temperature state LCD MODULE of operate as normal.
Background technology
Liquid crystal display (LCD) is to utilize liquid crystal molecule to change its optical characteristics under External Electrical Field and the display device made, it has polytype, and can be widely used on the products such as wrist-watch, counter, instrument, portable computer, micro television, monitor.Because the character of liquid crystal itself determines that the minimum temperature that present LCD can normally show is-35 ℃, phenomenons such as delay, hangover will occur when being lower than this temperature, influences display quality.And some LCD need be lower than as the fuel charger LCD under-35 ℃ the ultralow temperature state and is using.The LCD of using on the existing fuel charger is made of printed circuit board (PCB), LED-backlit source and LCD, and they the problems referred to above can occur when using under the ultralow temperature state.
Summary of the invention
The purpose of this utility model is to provide a kind of heater element that is provided with, thereby the LCD MODULE that can normally use under condition of ultralow temperature.
For achieving the above object, the utility model provide a kind of can be in the LCD MODULE of operate as normal under the ultralow temperature, it comprises printed circuit board (PCB) 10, LED-backlit source 20 and LCD 30, it is characterized in that, is provided with heater element 40 between LED-backlit source 20 and LCD 30.
Described heater element 40 is the glass plate 40 of band transparent conductive film.
40 liang of minor face edges of band transparent conductive film glass plate are equipped with electrode 41.
The electrode 41 of band transparent conductive film glass plate is plugged in the jack 11 of printed circuit board (PCB) 10 both sides of the edge.
Good effect of the present utility model is that it has thoroughly solved the demonstration problem of LCD at low temperature below-35 ℃.Owing to heating is housed between backlight and LCD with being with transparent conductive film (ITO) glass plate, thereby can heat LCD when under the ultralow temperature situation, using, even make display module under-50 ℃ ultralow temperature state, still can normally use.The utility model efficiently solves the problem that outdoor LCD MODULE such as fuel charger is used at north of china in winter.The also ingenious connectivity problem that has solved band transparent conductive film (ITO) glass plate and other parts of module of the utility model, and have problems such as simple in structure, easy to implement.
