Description
Technical field
The utility model belongs to LCDs technical field, relates in particular to a kind of semi-transparent LCDs.
Background technology
With the development of technology, from the eighties in last century, China has started the introduction of flat display technology, nowadays,
Panel display screen has already taken up the dominant position of field of display, and various LCDs are full of in the life of people.Such as：
Station shopping guide, elevator card, tube advertising, mobile unit etc..LCDs on existing market is all full impregnated light liquid crystal
Display screen, the problem of this LCDs is present are that its visible angle is very narrow and the backlight that must arrange in pairs or groups is used.Especially
When the product for carrying LCDs is carried out out of doors in use, can be because the influence of screen sunlight reflection causes not seeing screen
The picture of display, user, which must constantly adjust the relative angle of human eye and product and backlight illumination is adjusted into maximum, can just see clearly
Display picture, cause using the waste in upper inconvenience and energy consumption.Therefore, a kind of new LCDs how is developed,
The visible angle of display screen can effectively be expanded, without adjustment angle and improve back light brightness with regard to product can be enable in sun
Used in the abundant outdoor environment of light, be the direction that those skilled in the art need to study.
Utility model content
The utility model provides a kind of semi-transparent LCDs, can obtain bigger visible angle, and utilization is external
Light source reduces the demand to backlight illumination, reduces power consumption, is suitable for application in outdoor products.
The concrete technical scheme that it is used is as follows：
A kind of semi-transparent LCDs, including：Liquid crystal panel, backlight module and LED light source and OCA optical cement layers.Institute
Liquid crystal panel is stated by the sequentially stack first semi-transparent polaroid, the first glass-base, liquid crystal layer, the second glass-base and the second half
Saturating polaroid is formed；The backlight module is made up of the blooming piece, light guide plate and optical reflection piece sequentially stacked；The LED
Light source is fixed on light guide plate by way of welding；The OCA optical cement layers located at the liquid crystal panel and backlight module it
Between；The OCA optical cement layers side is bonded on the second semi-transparent polaroid, opposite side is bonded on blooming piece.
By using this technical scheme：By setting semi-transparent polaroid in the both sides of liquid crystal panel, increase to exterior light
The reflectivity of line, by setting OCA optical cement layers between liquid crystal panel and backlight module, enhance semi-transparent LCDs
Contrast under strong illumination, expands viewing area, and screen pattern is shown using the reflected light of ambient light, so as to
Reduce the brightness of back light, reduce the power of back light, reduce energy consumption.
Preferably, in above-mentioned semi-transparent LCDs：First glass-base uses translucent glass substrate structure
Into.
It is further preferred that second glass-base is also formed using translucent glass substrate.
Compared with prior art, the utility model viewing area is big, and back light energy consumption is low, can utilize the anti-of ambient light
Penetrate light to show screen pattern, the display screen for being suitable as being applied to the electronic products of semi-open environment such as open air uses.
Brief description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the utility model embodiment 1.
Each reference and component names corresponding relation are as follows：
1st, liquid crystal panel；2nd, backlight module；3rd, LED light source；4th, OCA optical cement layers；11st, the first semi-transparent polaroid；12nd,

23rd, optical reflection piece.
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the utility model is made into one below in conjunction with accompanying drawing
Step description.
It is the structure of embodiment 1 of the present utility model as shown in Figure 1：
A kind of semi-transparent LCDs, including：Liquid crystal panel 1, backlight module 2, LED light source 3 and OCA optical cement layers 4.
Wherein, the liquid crystal panel 1 is by the sequentially stack first semi-transparent polaroid 11, the first glass-base 12, liquid crystal layer
13, the second glass-base 14 and the second semi-transparent polaroid 15 are formed；The backlight module 2 by sequentially stack blooming piece 21,
Light guide plate 22 and optical reflection piece 23 are formed；The LED light source 3 is fixed on by way of welding on light guide plate 22；OCA optics
Glue-line 4 is located between the liquid crystal panel 1 and backlight module 2.Specifically, the side of OCA optical cement layers 4 is bonded in second
On semi-transparent polaroid 15, opposite side is bonded on blooming piece 21.First glass-base 12 uses translucent glass substrate
Form.Second glass-base 14 is formed using translucent glass substrate.
In practice：When the electronic product using the utility model as display screen, to be placed on the external light sources such as open air abundant
Carried out in environment in use, extraneous light is during liquid crystal panel 1 and backlight module 2 is sequentially passed through, successively the first half
Part is produced at 11 and second semi-transparent polaroid 15 of saturating polaroid to reflect, and is reached reaching its reflectivity at the second glass-base 12
10%, so as to be presented using the reflective of ambient light to screen-picture, the output intensity of back light is reduced, is reduced
Energy consumption.And OCA optical cement layers 4 have the function that anti-dazzle, solves semi-transparent LCDs under solar radiation because reflective
And the problem of not seeing screen, add the viewing area of display screen.
It is described above, only specific embodiment of the utility model, but the scope of protection of the utility model is not limited to
This, any those skilled in the art is in the change that in technical scope, can be readily occurred in disclosed in the utility model
Or replace, it should all cover within the scope of protection of the utility model.The scope of protection of the utility model is with claims
Protection domain is defined.
