Abstract
A double-sided LCD comprises a transmission LCD module, a pair of light conductive plates separately located on both sides of the LCD module and at least one light source to provide light of the light conductive plate. The LCD in this invention has single display module through double sides. Especially it is used as LCD of a cover style display of electron products .It can effectively decrease its thickness and increase the waiting time of the electron products such as cell phone.
Description
Technical field
The present invention relates to a kind of LCD of double-sided display, refer to a kind of LCD that has the single display module and can double-sided display especially, especially can be applicable to the cover-lifting type electronic product that the two sides shows.Background technology
Along with the development of information-based, communication and networking, compact Portable mobile product becomes important electron articles for use in the daily life, and the liquid crystal flat panel display in the product (Liquid CrystalDisplay LCD) becomes important parts.Because LCD itself is not luminous, therefore need one to add area source, display effect even, high brightness is provided, according to its light source mechanism, LCD can be divided into two kinds in the prior art, sees also Fig. 1, Fig. 2, is respectively backlight module and front light-source module.Wherein backlight module 1a is mainly used in penetration or half-penetration type panel, provide liquid crystal panel one light source 10a, be generally a little or linear light source, cooperate a reflex housing 11a, enter light guide plate 13a by reflector plate 12a, the conversion distribution of light sources is the area source of equal brightness, and the light harvesting of the equal light action of process diffusion sheet 14a and rhombus lens 15a is done in order to the brightness of raising light source and all spent together again; Front light-source module 2a is mainly used in reflective LCD panel 24a, its principle is with point or linear light source 20a, enter light guide plate 22a through reflex housing 21a, utilization light guide plate 22a front end face as the once-forming microstructure 23a of triangle water chestnut post to transform the area source of light source Cheng Junhui.
When the cover-lifting type electronic product of liquid crystal display applications in double-sided display type, in the time of for example on the mobile phone, be reduced volume and increase colour display functions, current trends are towards the function of development clamshell phone and tool double-sided display type.See also Fig. 3 A and Fig. 3 B, yet the double-sided display function of this clamshell phone 100a, actual is to adopt two LCD, usually the chromatic liquid crystal screen curtain 200a that has a demonstration key frame is located at single colour liquid crystal display curtain 300a inner and a demonstration subframe and is located at the outside, is equipped with backlight (scheming slightly) in the middle of it.So not only cause the increase of mobile phone thickness, the raising of manufacturing cost, and also power consumption and shorten the cell phone standby time easily of mobile phone can't be satisfied mobile phone faceplate slimming and light-weighted growth requirement.
The inventor is because the defective of prior art, also cooperates theoretical utilization through continuous thinking research, proposes a kind of design of LCD that can double-sided display, in the time of especially on being applied to mobile phone, can effectively improve its thickness.
Summary of the invention
Fundamental purpose of the present invention provides a kind of LCD of double-sided display type, the LCD that mainly provides a kind of tool single display module and can two-sidedly watch, when particularly being applied to have the LCD on the electronic product of cover-lifting type display, can effectively reduce its thickness, reduce manufacturing cost, and increase this electronic product, mobile phone for example, stand-by time.
To achieve the above object, the invention provides a kind of LCD of double-sided display type, comprise a penetration LCD MODULE; A pair of light guide plate is adjacent to the both sides of this LCD MODULE respectively; And at least one light source is for should be to light guide plate light.
The present invention also provides a kind of cover-lifting type electronic product with LCD of double-sided display type, comprise: a display panel, LCD with a double-sided display type is located at inside, wherein the LCD of this double-sided display type includes a penetration LCD MODULE, a pair of light guide plate is arranged at the both sides of this LCD MODULE respectively, and at least one light source is for should be to light guide plate light; One operating portion has a plurality of operation push-buttons and is located at its surface; And a junction connects this display panel and this operating portion.
The invention has the beneficial effects as follows,, when particularly being applied to the cover-lifting type electronic product, can reducing its thickness, and reduce cost by the LCD of double-sided display type of the present invention.
The invention will be further described below in conjunction with the drawings and specific embodiments.
