Method reflects away, and the setting of this structure is more cost-effective, is advantageous to produce and improve yields.
Brief description of the drawings
Fig. 1 is the schematic diagram 1 of liquid crystal display device in the utility model；
Fig. 2 is the schematic diagram 2 of liquid crystal display device in the utility model.
Embodiment
To make embodiment technical problems to be solved of the present utility model, technical scheme and beneficial effect clearer,
It is described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in figure 1, a kind of liquid crystal display device, from top to bottom successively by touch-screen 1, rotatory polarization piece 3 and display module 2
Composition, the display module 2 is pasted by LCD 21 and backlight module 22 to be formed, and the rotatory polarization piece 3 is by First Line polaroid 31
Formed with quarter-wave phase delay chip 32, the First Line polaroid 31 and quarter-wave phase delay chip 32 are used
About 5 μm of PSA glue carries out compound stickup.The rotatory polarization piece 3 can be that left-handed rotatory polarization piece can also be dextrorotation rotatory polarization piece,
In the present embodiment by taking left-handed rotatory polarization piece as an example.
As further improvement of this embodiment, the First Line polaroid 31 is affixed directly under the touch-screen 1
Surface, the LCD 21 are pasted with quarter-wave phase delay chip 32 by the frame glue 6 cut, the LCD 21 with
Air layer 4 is left between quarter-wave phase delay chip 32.By by LCD 21 and quarter-wave phase delay chip
32 are pasted with the frame glue 6 that has cut and make to leave air layer 4 among both, and in the prior art by LCD and quarter-wave
Phase delay chip optical cement edge paste compared to it is more cost-effective, be advantageous to produce and improve yields because optical cement
It is divided into solid state optics glue and optics of liquids glue, if be bonded with liquid optics, needs to paint frame shape with gluing instrument, after bonding
Resolidification, it is cumbersome, and because TP has ink to block the solidification that UV light is unfavorable for optical cement；If using solid state optics
Glue, need after bonding with machine pressing and then deaeration again, it is same cumbersome.By in the lower surface of touch-screen 1 in the present embodiment
The reflection of light is prevented using rotatory polarization piece 3, is prevented in LCD structure compared with prior art on liquid crystal display using rotatory polarization piece
The effect of light reflection is more preferable, and by the way that First Line polaroid 31 to be affixed directly to the lower surface of the touch-screen 1, is not required to pair
Polaroid surface or touch screen surface are surface-treated.By taking 5 cun of display screens as an example, to polaroid surface or touch-screen table
The price that face is surface-treated can increase by 50% or so, therefore present embodiment has the characteristics that cost is low, Feasible degree is high.
As a further improvement, the First Line polaroid 31 is pasted onto the touch-screen 1 by about 20 μm of PSA glue 5
Lower surface, the material of the frame glue 6 is double-sided adhesive, is advantageous to cost improvement.
As shown in Fig. 2 as a further improvement, the second line polarisation is pasted between the touch-screen 1 and line polarisation piece 31
Piece 7, the angle of the line polarisation piece 7 of First Line polaroid 31 and second at an angle, the setting of the second line polarisation piece 7
The reflectivity of light in full band range can be made to reach unanimity, finally make display screen background color uniform, realize the black effect of one.It is preferred that
Ground, the angle of the line polarisation piece 7 of First Line polaroid 31 and second is 50 ° -70 °.
Backlight module 22 described in the utility model include anti-dazzling screen, upper bright enhancement film, lower bright enhancement film, diffusion barrier, FPC,
LED, FPC double-sided adhesive, light guide plate, glue frame and reflector plate, the backlight module 22 are used to provide light source to the display module 2.
In the present embodiment, to make the light everywhere of touch-screen 1 filter out uniformly, the shape and size of the rotatory polarization piece 3 are equal
It is consistent with touch-screen 1.To reduce cost, the rotatory polarization piece 3 is silica rotatory polarization piece.The thickness of the rotatory polarization piece 3
Between 0.05-0.2mm, existing preferable optical absorption, the thickness of too many screen construction will not be increased again.
When display module 2 is not luminous, natural light of the light source from the external world, natural light can become after line polarisation piece 31
Perpendicular to the linearly polarized light of absorption axiss, linearly polarized light becomes circularly polarized light after quarter-wave phase delay chip 32,
Circularly polarized light incidence display module 2 is inverted behind surface, and quarter-wave is passed through in the circularly polarized light reflection after inverting
The linearly polarized light become again after phase delay chip 32 has just turned 90 ° with linearly polarized light during incidence, the absorption with line polarisation piece 31
Axle is parallel and is sponged by line polarisation piece 31, so as to make extraneous incident light not reflect back, reaches display module 2 and is not lighting
In the case of reduce brightness of display screen purpose, display screen seemed enough black, improved grade.
It is last it should be noted that above example is only illustrating the technical scheme of the embodiment of the present invention rather than it is entered
Row limitation, although the embodiment of the present invention is described in detail with reference to preferred embodiment, one of ordinary skill in the art
It should be understood that can still be modified to the technical scheme of the embodiment of the present invention or equivalent substitution, and these modifications or wait
The scope of amended technical scheme disengaging technical scheme of the embodiment of the present invention can not also be made with replacement.
