Description
Technical field
The utility model relates to substrate for liquid crystal display panel, relates in particular to a kind of substrate for liquid crystal display panel that has the contraposition cut mark.
Background technology
Make the field in LCD, make display panels and generally include following process: at first make display panels with thin-film transistor array base-plate and display panels colored filter substrate, then thin-film transistor array base-plate and colored filter substrate are carried out box; After box technology finished, need and to form display panels to thin-film transistor array base-plate behind the box and colored filter substrate cutting up and down.Before to box thin-film transistor array base-plate and colored filter substrate, normally alignment mark is set in non-panel (dummy) zone of thin-film transistor array base-plate and colored filter substrate, computer Recognition goes out the positional information of alignment mark, positional information according to alignment mark will be placed in the cutting equipment to the substrate for liquid crystal display panel behind the box exactly, and then cut, detect the accuracy of cutting at last according to cut mark.
Fig. 1 be the 5th generation line (the alignment mark position view of 15 cun substrate for liquid crystal display panel of the cutting of 1100mm * 1300mm).As shown in Figure 1, display panels 1 is positioned to be cut on the substrate for liquid crystal display panel behind the box 2, four top corner regions of display panels 1 are represented by first area 31, second area 32, the 33 and the 4th zone 34, the 3rd zone respectively, be respectively arranged with two alignment marks 201 in four zones, all be positioned at the dummy zone outside the display panels 1, the drift angle place of thin-film transistor array base-plate and colored filter substrate also is provided with cut mark 501, and wherein alignment mark 201 and cut mark 501 are criss-cross zhou duicheng tuxing.In each zone, two alignment marks 201 are represented the alignment mark of horizontal direction and the alignment mark of longitudinal direction respectively, concrete, the alignment mark of the horizontal direction of the alignment mark 201 difference counterpart substrates in first area 31, second area 32, the 3rd zone 33,34 4 zones, the 4th zone and the alignment mark of longitudinal direction.Read out the positional information of alignment mark 201 in dummy zone on the substrate for liquid crystal display panel 2 by computer Recognition after, the upper and lower base plate cutting is formed display panels.Can be earlier along the horizontal direction cutting of upper and lower base plate, cutting in a longitudinal direction more also can be earlier along the longitudinal direction cutting of upper and lower base plate, and transversely direction is cut again, and cutting sequence is unaffected.Read cut mark in the display panels by computer Recognition after cutting is finished, detect the order of accuarcy of cutting technique.
