Description
Technical field
The present invention relates to display technique field, particularly relate to a kind of double vision display module that simultaneously can show two pictures.
Background technology
Double vision shows, refer to that a display screen presents two different pictures in different angles simultaneously, such as be applied on vehicle display, the picture seen from the angle of driver is the picture navigated, and be the amusement pictures such as film from the picture that the angle of passenger is seen, so can give the guide of driver's route, passenger's body and mind can also be made joyful simultaneously, and not affect driver.
Double vision display technique the most frequently used is at present that grating blocks, beholder the side of display screen can only see by backlight by grating slit after the dual pixel of display screen that illuminates arrange, opposite side then can only see by backlight by grating slit after the strange pixel column of display screen that illuminates, as long as dual pixel row and the strange pixel column of display screen like this show two kinds of different images respectively, the beholder of display screen both sides just can be made to see different images.But, because backlight power need be launched to both direction by this kind of double vision display structure respectively, the brightness of each viewpoint just decreases, in addition the aperture opening ratio of grating is usually only about 20%, block a large amount of light, display brightness has been reduced greatly, is generally and meets display brightness, significantly can increase the brightness of backlight, so then add the energy consumption of whole double vision display module.
Prior art is compared, double vision of the present invention display module block grating is provided with reflective coating, by backlight, the light reflection be radiated on reflective coating returns backlight, then penetrate after again or repeatedly reflecting, reflecting, realize the utilization again of luminous energy, carrying the light emission rate of display module, under the prerequisite of the brightness without the need to promoting backlight, ensureing the emitting brightness of display module.
Summary of the invention
In view of this, provide a kind of brightness higher and the double vision that energy consumption is lower display module.
A kind of double vision display module, comprise backlight and display panel, described display panel comprises display screen and blocks grating, the described grating that blocks is between display screen and backlight, comprise substrate, be formed at the reflective coating on substrate and be formed at and reflective coating blocks rete, the described rete that blocks is formed with slit bright dipping, blocks rete light out part and divides with not bright dipping part in proportion in periodic distribution, and described reflective coating shape and structure is with to block rete identical.

Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 1, double vision of the present invention display module 100 comprises backlight 20 and is placed in the display panel 40 of light emission side of backlight 20.
In the present embodiment, described backlight 20 is twocouese backlight, comprises reflecting plate 22, the light source 24 be arranged on reflecting plate 22, is arranged at the light guide plate 26 of the light emission side of light source 24 and is arranged at the prism 28 of light emission side of light guide plate 26.Preferably, described light source 24 is LED, and certain light source 24 is not limited to LED, also can be other light source.The light that described reflecting plate 22 penetrates towards reflecting plate 22 for reflection source 24, makes the luminous light of light source 24 be penetrated by light guide plate 26 as much as possible, promotes the light emission rate of backlight 20.Described prism 28 is double-sided prism film, in order to adjust the angle of the light that light source 24 penetrates via light guide plate 26, makes it penetrate towards the both sides of display panel 40 as much as possible, crosstalk reduction, expands visual angle.
Described display panel 40, for providing displaying contents needed for left and right visual angle, comprises display screen 60 and blocks grating 80.In the present embodiment, described display screen 60 is custom liquid crystals display screen, for multilayer laminate constructions, comprise the glass substrate 62 of spaced setting, color membrane substrates 68, be formed at color film 64 inside color membrane substrates 68, and be arranged at the liquid crystal 66 etc. between glass substrate 62 and color film 64.For simplicity of illustration, the part-structure of display screen 60, as not shown in thin film transistor (TFT) (TFT), matrix pattern etc.Certainly, described display panel 40 is not limited to LCDs.
In the present embodiment, described in block grating 80 for the rear-mounted grating that blocks, be arranged at the rear of display screen 60, namely between display screen 60 and backlight 20.Two polaroids 90 are connected to the outside that display screen 60 blocks the outside of grating 80 and the color membrane substrates 68 of display screen 60, the angle of adjustment light, expand the visual angle of double vision of the present invention display module 100 further.
The described grating 80 that blocks is for blocking the some light of backlight 20, make double vision of the present invention show module 100 and present double vision effect, comprise substrate 82, be arranged at the reflective coating 84 on substrate 82 and be arranged at and reflective coating 84 blocks rete 86, described substrate 82 is transparent glass substrate, as reflective coating 84 and the carrier blocking rete 86.The described grating 80 that blocks is fitted with display screen 60 contraposition, and laminating gap, the distance of namely blocking between rete 86 and the color film 64 of display screen 60 is 0.15 ~ 0.25mm.
The described rete 86 that blocks is for black film, be formed with slit printing opacity, light transmission part (i.e. slit) and lightproof part are according to a certain percentage in periodic distribution, distribution period is relevant to the pixel of display screen 60, in the present embodiment, the ratio of described black film light transmission part and lightproof part is approximately 1.7 ~ 1.9 times of display screen 60 pixel size.
Described reflective coating 84 is metal film, for backlight 20 light reflection be radiated on reflective coating 84 is returned backlight 20, then penetrate after again or repeatedly reflecting, reflecting, realize the utilization again of luminous energy, carrying the light emission rate of double vision of the present invention display module 100, under the prerequisite of the brightness without the need to promoting backlight 20, ensureing the emitting brightness of double vision of the present invention display module 100.Described reflective coating 84 is blocking between rete 86 and substrate 82, with block rete 86 there is same shape and structure, that is reflective coating 84 is provided with slit bright dipping equally, its light transmission part is same with lightproof part according to a certain percentage in periodic distribution, described in block the ratio of rete 86 identical with blocking rete 86.
Double vision of the present invention display module 100 carries and rear-mountedly blocks grating 80 on display panel 40, block on grating 80 and increase reflective coating 84, obviously can promoting the utilization factor of the energy of backlight 20, being effectively lifted out luminance brightness when not increasing double vision of the present invention display module 100 energy consumption; Backlight 20 adopted in addition is twocouese backlight, obviously can promote the visual range of double vision of the present invention display module 100, crosstalk reduction, improve display performance.
