Description
Technical field
The present invention relates to display technique field, particularly relate to a kind of liquid crystal motherboard, for the sealed plastic box painting method of this liquid crystal motherboard and the liquid crystal panel by the cutting of this liquid crystal motherboard.
Background technology
Liquid crystal indicator (LCD, Liquid Crystal Display) there is compact, low-power consumption and the many merits such as low in calories, these advantages make liquid crystal indicator show one's talent in numerous dissimilar display device, are widely used on the modernization information equipments such as TV, computing machine, panel computer and mobile phone.
At present, along with the continuous maturation of flat panel display technology, consumer has turned one's attention to outward appearance and its diversified function of flat-panel screens gradually, so, now adopt the flat-panel screens of narrow frame design of common occurrence in the market.Adopt the flat-panel screens of narrow frame design, its volume can compress to greatest extent, simultaneously, also effectively makes people think that effective area is more open, and therefore, this narrow frame design is trend and the developing direction of following flat-panel screens.
As shown in Figure 1, 2, in existing liquid crystal display, need to use the upper and lower base plate (as color membrane substrates 101 and array base palte 102) of sealed plastic box 104 pairs of liquid crystal motherboards 100 to cohere, sealed plastic box 104 is coated on the outside of single liquid crystal panel (i.e. the liquid crystal panel viewing area 103 of liquid crystal motherboard 100) usually.As shown in Figure 2, the width b of sealed plastic box 104 itself, sealed plastic box 104 determines the border width of liquid crystal panel apart from the distance a of liquid crystal panel viewing area 103 and sealed plastic box 104 jointly apart from the distance c of display panel line of cut 105, therefore, can by reducing the width a of sealed plastic box 104, reduce sealed plastic box 104 apart from the distance a of liquid crystal panel viewing area 103 and reduce sealed plastic box 104 to reduce liquid crystal panel border width apart from the method for the distance c of display panel line of cut 105, but, on the other hand, the width reducing sealed plastic box 104 may cause sealed plastic box 104 apply bad or cohere bad, and reduce sealed plastic box 104 may cause sealed plastic box 104 pairs of liquid crystal panel viewing area 103 liquid crystal pollution to the distance of liquid crystal panel viewing area 103, cause display bad, in sum, only have and reduce sealed plastic box 104 can reduce display panel effectively border width to the distance of display panel line of cut 105.
There is a kind of method using cut in prior art, inactive area beyond sealed plastic box edge can be excised, even can cut from sealed plastic box, thus ensure that the border width of display panel; Also someone proposes and only apply a sealed plastic box between two display panel, and then cuts from sealed plastic box central authorities, thus effectively utilizes substrate also can reduce the border width of display panel.But above two kinds of methods have following shortcoming: although adopt the method for cut effective, considerably increase the cost of equipment, the complicacy of operation and running time, reduce production efficiency, and easily occur damaging product, even occur security incident; And when adopting the method for an only coating sealed plastic box between two display panels, owing to directly cutting sealed plastic box, adopt and the problems such as cutting is bad during conventional method cutting, to be produced, the serious quality that have impact on product.So above two kinds of methods not can solve the narrow frame design problem of display panel.
