Abstract
The utility model discloses a substrate and a display device provided with the same. The substrate comprises a PI dam used for blocking diffusion of PI liquid in the spraying process. According to the substrate used for a liquid crystal display, the PI dam is arranged on the substrate, and therefore the PI liquid is blocked by the PI dam in the spraying process and forms a liquid crystal alignment layer which is good in edge linearity and evenness. Adverse effect and uneven edge dimensions caused by unevenness of the edge of the liquid crystal alignment layer can be reduced. The substrate and the display device provided with the same can be used for the technology of narrow-frame liquid crystal display.
Description
Technical field
The utility model relates to display technique field, relates in particular to a kind of substrate and the display device with this substrate.
Background technology
Liquid crystal display, comprises array base palte, color membrane substrates and the layer of liquid crystal molecule between array base palte and color membrane substrates.Conventionally for what accelerate the deflection of liquid crystal molecule or form different liquid crystal molecules, play folk prescription to form the larger visual angle of watching, at array base palte and color membrane substrates, in the viewing area of liquid crystal molecule side, be all provided with liquid crystal orientation film.Liquid crystal orientation film is by being sprayed on array base palte or color membrane substrates by spraying coating process as the liquid of the hydrophilic oleophobic properties such as polyimide (PI).
In at present conventional PI liquid spraying coating process, for the PI drop that makes to drip better merges film forming, PI liquid used needs good mobility, but just because of this, the edge free diffusing of PI liquid in film forming procedure, the non-uniform areas of formation is large, and rectilinearity is poor, periphery film quality is poor, and drying and forming-film back edge presents zigzag by a relatively large margin.Non-uniform areas can take peripheral size simultaneously, is unfavorable for the exploitation of narrow frame technology.As described in Figure 1, the substrate 1(of prior art is array base palte or color membrane substrates) be divided into a plurality of display panels, described display panel comprises non-display area 2 and viewing area 3, non-display area 2 is for circuit structure of integrated liquid crystal display etc., viewing area 3 is for spraying PI liquid to form liquid crystal orientation film, but in spraying process because the mobility of PI liquid often makes the liquid crystal aligning film edge homogeneity and the non-constant of rectilinearity that form, as zigzag by a relatively large margin etc.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is: a kind of raising liquid crystal aligning film edge homogeneity and linear substrate and display device are provided.
(2) technical scheme
For addressing the above problem, the utility model provides a kind of substrate for liquid crystal display on the one hand, and described substrate comprises PI dam, for stopping the diffusion of PI liquid spraying process PI liquid.
Preferably, described PI dam is one deck inertia rete.
Preferably, described PI dam arranges around the viewing area of the display panel on described substrate.
Preferably, the height on described PI dam is greater than the rete height of the liquid crystal orientation film being formed by PI liquid.
Preferably, described PI dam is hollow strip form film.
Preferably, described substrate is array base palte or color membrane substrates.
On the other hand, the utility model also provides a kind of display device, comprises above-mentioned substrate.
(3) beneficial effect
The substrate for liquid crystal display of the utility model embodiment, by PI dam is set on substrate, makes PI liquid in spraying process, be subject to stopping of PI dam and forms edge line and the liquid crystal orientation film that has good uniformity.Bad and the marginal dimension that minimizing brings because liquid crystal aligning film edge is inhomogeneous, can be for narrow frame lcd technology.
Accompanying drawing explanation
Fig. 1 is the board structure schematic diagram for liquid crystal display of prior art;
Fig. 2 is the board structure schematic diagram for liquid crystal display of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated as follows.
As shown in Figure 2, the substrate 1 for liquid crystal display the utility model proposes, described substrate 1 comprises PI dam 4, for spraying PI liquid process, stops that PI liquid diffuses to non-display area.
Before PI liquid coating processes, by applying the composition techniques such as exposure imaging etching, at non-display area, one deck inertia rete is set, described rete is looped around viewing area periphery, can be called PI dam, and then carries out PI liquid coating processes.
Described PI dam 4 can be one deck inertia rete, and such as photoresist (PR glue) etc., photoresist has extensive application in the preparation technology of array base palte and color membrane substrates, simple and convenient for realizing PI dam.Usually, described PI dam 4 arranges around the viewing area 3 of the display panel on described substrate 1, and the liquid crystal orientation film that PI liquid is formed is controlled in viewing area 3.
For fear of PI hydrorrhea, go out, generally, the height on described PI dam 4 is greater than the rete height of the liquid crystal orientation film of the PI liquid formation that will spray.The rete high computational formula of the liquid crystal orientation film that the described PI liquid that will spray forms is: H=V/S, wherein H is the rete height of the liquid crystal orientation film that forms of PI liquid, V for the PI liquid that will spray long-pending, the area that S is the display panel that will spray.The width on PI dam does not limit, according to process requirements setting.
Described PI dam 4 can be for hollow strip form film etc., specifically according to the shape of viewing area 3, determines.
Described substrate 1 is generally array base palte or color membrane substrates.
The above-mentioned substrate for liquid crystal display, by PI dam is set on substrate, makes PI liquid in spraying process, be subject to stopping of PI dam and forms edge line and the liquid crystal orientation film that has good uniformity.Bad and the marginal dimension that minimizing brings because liquid crystal aligning film edge is inhomogeneous.After liquid crystal orientation film is stable, can also PI dam be removed by etching technics, can not exert an influence to subsequent technique.
On the other hand, the utility model also provides a kind of display device, comprises above-mentioned substrate.
This display device can be: any product or parts with Presentation Function such as liquid crystal panel, Electronic Paper, oled panel, mobile phone, panel computer, televisor, display, notebook computer, digital album (digital photo frame), navigating instrument.
Above embodiment is only for illustrating the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
