Description
Technical field
The invention relates to a kind of liquid crystal panel motherboard and cutting method thereof.
Background technology
At present because LCD has gently, characteristics such as thin, little, be widely used in desktop computer, kneetop computer, personal digital assistant (Personal DigitalAssistant, PDA) with multiple office automation and audio-visual equipment in.LCD replaces conventional cathode ray tube (Cathode Ray Tube, CRT) display just gradually.
Liquid crystal panel is the main element of LCD, in the manufacturing process of liquid crystal panel, usually a bigger liquid crystal panel motherboard is cut according to product size, forms a plurality of liquid crystal cells.
See also Fig. 1 and Fig. 2, Fig. 1 is a kind of floor map of prior art liquid crystal panel motherboard, and Fig. 2 is the diagrammatic cross-section of liquid crystal panel motherboard shown in Figure 1 along the II-II line.This liquid crystal panel motherboard 10 comprises one first mother substrate 110, one second mother substrate 120 and a plurality of frame glue 130.This second mother substrate 120 and these first mother substrate, 110 relative spacing settings, these a plurality of frame glue 130 of clamping.
This first mother substrate 110 comprises a plurality of thin film transistor base plates (not indicating), and these a plurality of thin film transistor base plates are matrix form and distribute.Each thin film transistor base plate comprises a viewing area 111 and a terminal region 112.This viewing area 111 is used for driving liquid crystal layer (figure does not show), shows that to realize picture this terminal region 112 is used for connecting outside line.Be positioned at the thin film transistor base plate with delegation, its terminal region 112 is arranged on the same side of viewing area 111, and the terminal region 112 of adjacent two row thin film transistor base plates is oppositely arranged.
This second mother substrate 120 comprises a plurality of colored filter substrates (not indicating), and the corresponding one by one setting of its a plurality of thin film transistor base plates with this first mother substrate 110 forms a plurality of liquid crystal cells 114.
These a plurality of frame glue 130 are coated in the edge of each viewing area 111 independently of each other, form a plurality of separate rectangular ring structures, between two adjacent rectangular ring frame glue 130, are formed with a plurality of interval regions 115.
When this liquid crystal panel motherboard 10 is carried out cutting splitting, along this interval region 115 a plurality of virtual lines of cut 140 are set, cut along 140 pairs of these first mother substrates of these a plurality of virtual lines of cut 110 and this second mother substrate 120, and, isolate each liquid crystal cell 114 along these two mother substrates 110,120 being carried out sliver perpendicular to the direction of this liquid crystal panel motherboard 10.
But, this interval region 115 is formed on outside each liquid crystal cell 114, after carrying out cutting splitting along 115 pairs of these liquid crystal panel motherboards 10 of this interval region, for each liquid crystal cell 114, its thin film transistor base plate and colored filter substrate all can exceed outside the scope that ring-type frame glue 130 defines.The part that these two substrates exceed outside the ring-type frame glue 130 is inoperative to the operate as normal of this liquid crystal cell 114, has therefore caused the waste of baseplate material, makes these liquid crystal panel motherboard 10 utilization efficiency of material lower.
In order to solve the lower problem of mother substrate material use efficient of prior art liquid crystal panel motherboard, be necessary to provide a kind of mother substrate stock utilization higher liquid crystal panel motherboard.
Also be necessary to provide a kind of cutting method of above-mentioned liquid crystal panel motherboard simultaneously.
A kind of liquid crystal panel motherboard, it comprises a mother substrate and a plurality of frame glue, these a plurality of frame glue are arranged on this mother substrate surface, define a plurality of viewing areas, and separate by single frame glue between per two adjacent display areas territories, this mother substrate further comprises terminal region, and this terminal region is used for connecting outside line, and one the 3rd colloid is arranged on the edge that terminal region reaches this viewing area adjacent with this terminal region.
A kind of liquid crystal panel motherboard, it comprises a mother substrate and a plurality of frame glue.This mother substrate comprises a plurality of viewing areas, these a plurality of frame glue are arranged on this mother substrate surface, these a plurality of frame glue the interval region that covers between per two adjacent display areas territories is set, this mother substrate further comprises terminal region, this terminal region is used for connecting outside line, and one the 3rd colloid is arranged on the edge that terminal region reaches this viewing area adjacent with this terminal region.
A kind of liquid crystal panel motherboard cutting method, it may further comprise the steps: one first mother substrate is provided, and this mother substrate comprises terminal region; A plurality of frame glue are provided, and it is coated in this first mother substrate, define a plurality of viewing areas adjacent, and make between per two adjacent display areas territories by single frame glue separation with terminal region; Colloid is provided, it is coated in the edge that terminal region reaches this viewing area adjacent with this terminal region; One second mother substrate is provided, and itself and this first mother substrate relative spacing is provided with, and these a plurality of frame glue of clamping are between these two mother substrates; Coating zone along these a plurality of frame glue between per two adjacent display areas territories cuts this liquid crystal panel motherboard, obtains a plurality of liquid crystal cells.
