Abstract
The utility model discloses a base board, a liquid crystal display panel and a liquid display device. The base board for the liquid crystal display panel comprises a quadrilateral display area formed by being defined through sealing glue, a starting endpoint and a stopping endpoint of the sealing glue on the periphery of the display area are overlapped to form a joint area, and the joint area is arranged at the position of a corner of the display area. Due to the fact that coating contacts are right at the corner, redundant sealing glue materials can be cut off directly during cutting. In addition, extrusion pollution of the materials caused by the contacts which are coated too thickly after extrusion of the sealing glue can be avoided, and multi-time cutting work can be reduced. The sealing joint area is arranged at the position of the corner of the display area and can not deviate from the display area, and a problem that line width is hard to control is solved.
Description
Technical field
The utility model relates to field of liquid crystal display, in particular, relates to a kind of substrate, display panels and liquid crystal indicator.
Background technology
Liquid crystal indicator comprises liquid crystal panel, and the production of liquid crystal panel all is on big panel sets, to cut formation by preliminary dimension, and big panel sets is fitted with the optical filtering substrate with a plurality of colored filters by the array base palte that includes thin film transistor (TFT) (TFT) and formed; Need before fitting to be coated with fluid sealant (sealant) on a substrate therein; Coating forms several quadrilateral areas, and this zone is the viewing area of liquid crystal panel, and the size of the liquid crystal panel of shape size and required cutting adapts; Dispenser method in said zone; Then two substrates are carried out hot pressing and fit, cut along the fluid sealant periphery back of fitting, and forms the liquid crystal panel of required size.The coating process of prior art originates on wherein frame of viewing area, can cross reference position when coating stops, and forms the handing-over section, to guarantee sealing.Because machining precision is restive, the glue amount on the handing-over section is often too much, after the pressing, the mutual pollution problems of storeroom is arranged easily, and the pollution such as to liquid crystal influences display quality; In addition, required glue material live width difficulty was controlled after handing-over section glue amount too much caused pressing.
U.S. Pat 7,408,614 disclose a kind of sealing graphic structure with and forming method thereof, as shown in Figure 1, outside the zone, begin earlier coating in the time of coating, form preliminary sectors; Inwardly bending into then, one side of viewing area begins formal coating operation; Bend the extension coating in the time of termination from inside to outside, form and stop section, preliminary sectors intersects to form the handing-over section with the termination section; Because overlapping area is little; Therefore the section that can effectively prevent to join is piled up excessive fluid sealant, but preliminary sectors all is toward outside sweep with stopping section in this method, and the section that therefore joins can depart from the frame at place; Make the border width at handing-over section place obviously greater than the width of other three frames of viewing area, still have required glue material live width problem rambunctious after the pressing; Section join in addition on frame, be not easy the position cutting of handing-over section smooth in the time of cutting.
The utility model content
The utility model technical matters to be solved provides a kind of handing-over section processing is smooth easily, glue material live width is controlled easily the substrate that is used for display panels, display panels and liquid crystal indicator of sealing.
The purpose of the utility model realizes through following technical scheme:
A kind of substrate that is used for display panels; Comprise by fluid sealant and surround the quadrilateral viewing area that forms; The initial end points of the fluid sealant of said viewing area periphery overlaps to form the handing-over section with the termination end points, and wherein said cross-connecting area section is positioned at the position, angle of said viewing area.
The initial end points of said fluid sealant with stop end points and outside position, said angle, continue to extend and be formed with preliminary sectors respectively and stop section, said preliminary sectors forms the handing-over section with the overlapping region that stops section.The feasible precision that need not painstakingly to control the coating operation of such design can be when guaranteeing the viewing area positiver sealing, and the section glue amount that also can not cause joining is too much.
Said preliminary sectors is mutually perpendicular straight-line segment with stopping section.
Said preliminary sectors is an arc with stopping section.
Said preliminary sectors is opposed each other with the aduncate side of termination section.
Said preliminary sectors is opposed each other with the bandy side of termination section.
A kind of display panels; Comprise substrate; Described substrate comprises the quadrilateral viewing area that is formed by the fluid sealant encirclement; The initial end points of the fluid sealant of said viewing area periphery overlaps to form the handing-over section with the termination end points, it is characterized in that said cross-connecting area section is positioned at the position, angle of said viewing area.
A kind of liquid crystal indicator, described liquid crystal indicator has used above-mentioned display panels.
The utility model since the coating contact that makes fluid sealant just on the corner, the coating contact just on the corner, makes when cutting, just can directly unnecessary sealant material be cut in the lump; Also can avoid fluid sealant in addition after pressing, cause the extruding of material to pollute because of the interface point coating weight is blocked up, and can reduce repeatedly and cut man-hour.Sealing handing-over section can not depart from the viewing area in the position, angle of viewing area, has solved the restive problem of live width; And the cross-connecting area section is positioned at the position, angle, and cutting twice can be accepted at this handing-over section when the viewing area frame cuts in the junction of two frames wherein in the viewing area, has improved the smooth degree of handing-over section.
