Description
[technical field]
The utility model relates to a kind of two-sided display liquid crystal display.
[background technology]
Because the liquid crystal itself in the panel of LCD does not possess the characteristics of luminescence, therefore in order to reach display effect, need to give the LCD panel to provide a planar light source device in order to realize Presentation Function, as backlight module, its function is to provide the area source that brightness is abundant and be evenly distributed to display panels.Usually backlight module comprises light source, reflector plate, light guide plate and diffuser plate.The incidence surface setting of the relative light guide plate of light source.The transmission direction that light-guide plate guides is sent light beam from light source will convert comparatively uniform in-plane light from the light of line source or pointolite in order to evenly to illuminate the display panels in the LCD.The light that the bottom surface of reflector plate reflection light guide plate is penetrated enters light guide plate, in order to reduce the loss of light.Diffuser plate will make light directive display panels more equably from the further scattering of the light of light guide plate outgoing.
Along with the progress in epoch, a lot of product needed display images on the tow sides of display screen.The function that LCD will reach double-sided display needs two LCD MODULE, be about to the submodule that two single faces show and be in juxtaposition, one inside one outwards, in order to realize positive and negative double-sided display.
A kind of two-sided display liquid crystal display of prior art as shown in Figure 1, this two-sided display liquid crystal display 100 comprises two display panels 110,111, in two light guide plate 114,115 between these two display panels 110,111, lay respectively between 116,117, two light guide plate 114,115 of two light sources of two light guide plate 114,115 1 sides and be provided with two reflector plates 118,119.Be provided with diffuser plate 112 between this light guide plate 114 and the display panels 110, be provided with diffuser plate 113 between light guide plate 115 and the display panels 111.Be provided with brightening piece 120 between display panels 110 and the diffuser plate 112, be provided with brightening piece 121 between display panels 111 and the diffuser plate 113.
The light guide plate 114 of this two-sided display liquid crystal display 100 is that branch is arranged with reflector plate 118 and light guide plate 115 with reflector plate 119.When assembling this two-sided display liquid crystal display 100, have the gap between light guide plate 114 and the reflector plate 118 and between light guide plate 115 and the reflector plate 119, there is air in this gap.From the light of light source 116,117, part penetrates the bottom surface of light guide plate 114,115 respectively, arrives reflector plate 118,119 through these two gaps respectively, after the reflection, gets back in the light guide plate 114,115 through these two gaps respectively again.In this transmission course, the loss of light will be caused.
[utility model content]
In order to overcome the phenomenon that prior art two-sided display liquid crystal display causes light loss, be necessary to provide a kind of two-sided display liquid crystal display that can reduce light loss.
Also be necessary to provide the another kind of two-sided display liquid crystal display that also can reduce light loss.
A kind of two-sided display liquid crystal display, it comprises two display panels that are oppositely arranged, two light guide plate that are oppositely arranged and the double-sided reflecting sheet between these two light guide plate.This double-sided reflecting sheet and this two light guide plate are one-body molded.These two light guide plate and this double-sided reflecting sheet are between these two display panels.
Another kind of two-sided display liquid crystal display, it comprises two display panels that are oppositely arranged, two light guide plate that are oppositely arranged and two reflector plates that are oppositely arranged between these two light guide plate.These two reflector plates are one-body molded with these two light guide plate respectively.These two reflector plates and this two light guide plate are between these two display panels.
Compared with prior art, the light guide plate of above-mentioned two two-sided display liquid crystal displays and reflector plate are to be combined into one by one-body molded mode.Thereby existence very close to each other between this light guide plate and the reflector plate enters the light of light guide plate, can directly reflect with the integrated reflector plate of light guide plate, penetrates light guide plate.Thereby can reduce propagation medium, can reduce the transmission path and the interface of light, and then reduce the loss of light.
