Description
Technical field
The present invention relates to LCD (LCD) panel, relate in particular to a kind of minimizing liquid crystal pollution and the panel of LCD that improves edge Mura (picture quality bad phenomenon).
Background technology
LCD (LCD) product developed very swift and violent in recent years, and its application is also constantly being widened, and more and more high-quality LCD are gone on the market gradually; Simultaneously many problems also occurred, for example liquid crystal pollution and Mura phenomenon cause the image quality reduction of LCD screen.
Please refer to Fig. 1, Figure 1 shows that color film substrate structure of the prior art, it comprises glass substrate 1, be formed on colored rete 2 and black matrix 3 on the glass substrate, colored rete 2 becomes pixel region with black matrix 3 mutual group, in the close glass substrate edge in the periphery of pixel region, scribble a circle envelope frame glue 4 usually.Please refer to Fig. 2, Figure 2 shows that the synoptic diagram behind 5 pairs of boxes of color membrane substrates 6 and array base palte, envelope frame glue 4 is encapsulated in liquid crystal 7 between color membrane substrates 6 and the array base palte 5.Because envelope frame glue material can be had an effect with liquid crystal molecule along with the influence of temperature, time and other technological factors usually, have a strong impact on the arrangement and the deflection of liquid crystal molecule and pollute.Because no any spacer between pixel region and the envelope frame glue zone, as shown in Figure 2, when on the high side or vacuum caused the pixel edges liquid crystal on the high side after to box when amount of liquid crystal, liquid crystal can contact with envelope frame glue, interact under certain conditions, thereby cause liquid crystal pollution.In addition, vacuum is in the box, under stronger Electrostatic Absorption and atmospheric effect, can cause chock insulator matter local behind the box and glass substrate making the liquid crystal display box thickness ununiformity even because of the stressed excessive excessive deformation that produces, thereby cause that edge Mura and other are bad.Moreover, liquid crystal also can owing to the wedge surface effect causes liquid crystal can not normal distribution, make normal zone not to be orientated normally, these all have in various degree influence to the demonstration image quality effect of liquid crystal display and yields.
Produce the situation of irregular colour in order to reduce panel of LCD because of the sealing frame, method of the prior art normally increases the distance between envelope frame glue and the effective pixel area, however the effective viewing area that can reduce liquid crystal panel like this.
Summary of the invention
The objective of the invention is defective, a kind of panel of LCD that reduces liquid crystal pollution and improve edge Mura is provided at prior art.
To achieve these goals, the invention provides a kind of panel of LCD, comprise color membrane substrates and the array base palte that is oppositely arranged, it is thick to keep box by chock insulator matter between color membrane substrates and the array base palte, be full of liquid crystal between color membrane substrates and the array base palte, have an envelope frame glue that two substrates is sealed around the pixel region of color membrane substrates and array base palte, wherein an isolation frame is arranged between the pixel region and envelope frame glue of described color membrane substrates and array base palte.
In the such scheme, the material of described isolation frame can be identical with the material of described chock insulator matter.Described isolation frame can be formed on the color membrane substrates or be formed on the array base palte.The height of described isolation frame is suitable with the height of described chock insulator matter.The bottom width of described isolation frame is that pixel edges arrives the distance 1/25～1/3 between the envelope frame glue.Described isolation frame is that pixel edges arrives the distance 1/16～1/3 between the envelope frame glue apart from the distance of envelope frame glue.One side of described isolation frame or polygon on be formed with a series of groove, being shaped as of groove is square, semicircle, arc, triangle or trapezoidal etc.; Perhaps be square, semicircle, arc, triangle or trapezoidal etc. combination in any.The degree of depth of described groove is 1/15～2/3 of a described isolation frame height.
The present invention is with respect to prior art, owing to isolate the special design of frame, can guarantee on the one hand liquid crystal not because of the wedge surface effect causes liquid crystal can not normal distribution, on the other hand, can control the liquid crystal flowing space in liquid crystal panel interior pixel zone effectively, also can prevent to a certain extent liquid crystal too much or expanded by heating cause unnecessary bad generation, thereby reduce liquid crystal on the one hand and envelope frame glue interacts, prevented liquid crystal pollution; It is thick to have stablized the liquid crystal display box on the other hand, has reduced the Mura phenomenon, has further improved the image quality effect of LCD.
Below in conjunction with the drawings and specific embodiments the present invention is illustrated in more detail.
