Description
The utility model relates to a kind of double-side liquid crystal display screen module.
The function that present liquid crystal display panel module will reach double-sided display needs two LCDs, is about to two single face display sub-modules and together, and one one outwardly inwardly.This structure cost energy consumption height, lead-in wire complexity undoubtedly causes reliability decrease, and because the quantity of information of inside and outside demonstration and the difference of content certainly will cause the LCDs utilization factor not high.With regard to the information terminal product, these defect influence are very large, especially to wherein portable product.
The purpose of this utility model is for providing a kind of liquid crystal display panel module that uses a LCDs just can realize double-sided display function.
For achieving the above object, the utility model is by the following technical solutions: it comprises the display unit that is provided with a LCDs, the back side of display unit is provided with light guide plate, be provided with backlight after the light guide plate, only a throw light on end of display unit of backlight, the size of the size of light guide plate and this end display unit adapts, front at display unit also is provided with light guide plate, be provided with backlight after the light guide plate, only the throw light on remaining part of display unit of backlight, the size of the size of light guide plate and this part display unit adapts.
When adopting above technical scheme, the utility model also can adopt following further technical scheme:
Described display unit also comprises preceding polaroid and the rear polarizer that is located at the LCDs front and back.
Owing to adopted above technical scheme, make the utility model utilize a LCDs just can realize the function of double-sided display dexterously, realize with two display screens that double-sided display functions are compared and reduced cost and energy consumption, owing to only use a LCDs, obviously reduce the complicacy that lead-in wire with former devices such as driver ics reduced circuit and increased reliability, can adjust two reflecting plates and lighting unit according to the quantity of information of inside and outside demonstration and the difference of content simultaneously, thereby the size of adjusting inside and outside display surface makes full use of display screen, can make things convenient for the information terminal product, particularly the use of portable product wherein.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the synoptic diagram of the display screen of the utility model embodiment.
With reference to accompanying drawing 1.The utility model comprises the display unit that is provided with a LCDs 1, and display unit also comprises preceding polaroid 2 and the rear polarizer 3 that is located at the LCDs front and back.The back side of display unit is provided with light guide plate 10, be provided with backlight 11 after the light guide plate, one end of 11 illumination display units of backlight, the size of the size of light guide plate 10 and this end display unit adapts, front at display unit also is provided with light guide plate 12, be provided with backlight 13 after the light guide plate 12, the remaining part of 13 illumination display units of backlight, the size of the size of light guide plate 12 and this part display unit adapts.
