Description
Technical field
The present invention relates to display device technical field, more particularly, to a kind of display screen and a kind of preparation side of display screen
Method.
Background technology
At present smart mobile phone is quickly popularized, the consumption idea of consumer from entry level to improving level transition, because
Generally the technological concept known to the masses such as all-metal, narrow frame, ultra-thin, Curved screen in this mobile phone industry.Either ultra-thin also
It is Curved screen, very crucial design considerations seek to reduce the thickness of each stacking of product as far as possible, realize the reduction of integral thickness, from
And realize product thinning and good flexibility.For touch screen, thinning scheme common at present is to try to reduce cover plate, thoroughly
The thickness of the film layers such as bright optical cement (Optically Clear Adhesive, OCA).But it is affected by before and after's section technology and technique
Limitation, is difficult to when the thickness of these materials reduces to a certain extent continue to reduce.Such as in the case that cover plate is maintained the statusquo, such as
Fruit reduces the thickness of transparent optical cement rashly, and deflection in the production process of touch screen for the transparent optical cement can be led to not enough,
The segment difference brought by decorative ink cannot smoothly be overcome, easily a large amount of bubbles occur, have a strong impact on the production yield of touch screen,
Thus affecting scale of mass production.
Content of the invention
The technical problem to be solved is to provide a kind of display screen of thinner thickness.
Additionally, also providing a kind of preparation method of display screen.
To achieve these goals, embodiment of the present invention adopts the following technical scheme that：
On the one hand, a kind of display screen is provided, including：
Cover plate；
Light shield layer, is formed on the first surface of described cover plate patterning；
Flatness layer, is formed in the region not covered by described light shield layer of described first surface and connects described shading
Layer, the second surface away from described cover plate of described flatness layer is put down away from the 3rd surface of described cover plate with described light shield layer
Together；
Adhered layer, is formed on described second surface and described 3rd surface；And
Display floater, is fitted on the surface away from described flatness layer of described adhered layer.
Wherein, the thickness of described flatness layer is equal with the thickness of described light shield layer.
Wherein, described flatness layer doping anti-glare material or optical clearing agent.
Wherein, described display screen also includes functional film layer, and it is flat with described that described functional film layer is located at described first surface
Between layer and connect described light shield layer, the thickness of described functional film layer and described flatness layer thickness and be equal to described light shield layer
Thickness.
Wherein, described functional film layer is anti-glare film or anti-reflection film.
Wherein, described first surface includes viewfinder area and encloses the invisible range setting the setting of described viewfinder area, described light shield layer
Positioned at described invisible range, described flatness layer is filled in described viewfinder area.
Wherein, described display floater includes touch layer and display layer, and it is aobvious with described that described touch layer is located at described adhered layer
Show between layer.
Wherein, described adhered layer adopts Optical transparent adhesive or optical clear resin material.
On the other hand, a kind of preparation method of display screen is also provided, including：
The light shield layer of patterning is formed on the first surface of described cover plate；
Form flatness layer in the region not covered by described light shield layer of described first surface, described flatness layer connects institute
State light shield layer, the 3rd table away from described cover plate of the second surface away from described cover plate of described flatness layer and described light shield layer
Face is concordant；And
By adhered layer, display floater is conformed to described second surface and described 3rd surface.
Wherein, described " forming flatness layer in the region not covered by described light shield layer of described first surface " includes：
By chemical vapor deposition manner or inkjet printing mode, not covered by described light shield layer in described first surface
Region in formed flatness layer.
Compared to prior art, the invention has the advantages that：
Because described flatness layer is put down with the surface away from described cover plate of described light shield layer away from the surface of described cover plate
Together, therefore described flatness layer is capable of the effect of described cover plate planarization, eliminates on described cover plate by described light shield layer institute
The segment difference brought, can be effectively prevented from the generation of bubble with described display floater during described cover plate is fitted, thus
Being capable of thinning described adhered layer, the integral thickness of the described display screen of reduction, the process rate of the described display screen of raising and display matter
Amount.In short, the thinner thickness of described display screen.
