Description
Technical field
The invention relates to a kind of display device, and particularly relevant for a kind of liquid crystal indicator.
Background technology
Liquid crystal indicator in recent years is being widely used in the daily life gradually, as the liquid crystal screen of LCD TV, laptop computer, desktop computer and liquid crystal projector etc.Liquid crystal projector one of indispensable instrument of giant display especially wherein, and the core of liquid crystal projector is the light engine that its projection is used.Light engine mainly comprises optical element that light source, some prism groups are constituted and the liquid crystal panel (panel) of each light path of a plurality of correspondence (red, green, blue).Above-mentioned liquid crystal panel adopt more silica-based liquid crystal panel (liquid crystal on silicon, LCOS), silica-based liquid crystal panel is a kind of reflective liquid crystal panel, it is that framework is on a silicon substrate (silicon back board).Since the silica-based liquid crystal panel framework on silicon substrate, volume is little and have good resolution, so silica-based liquid crystal panel is applied in the general liquid crystal projector is very common.In addition, silica-based liquid crystal panel extremely meets the demand that liquid crystal projector reduces day by day on volume.
At first please refer to Fig. 1, it illustrates the structural representation into known silica-based liquid crystal panel.Known silica-based liquid crystal panel 40 mainly comprises an infrabasal plate 10, a subtend substrate 20, a glue frame 32 and a liquid crystal layer 34.Wherein, subtend substrate 20 is disposed at infrabasal plate 10 tops, and glue frame 32 and liquid crystal layer 34 are disposed between infrabasal plate 10 and the subtend substrate 20, and liquid crystal layer 34 is positioned at glue frame 32 region surrounded.
Please refer to Fig. 2 A, its illustrate into known silica-based liquid crystal panel at the preceding structural representation of sliver (breaking).Generally speaking, the making of known silica-based liquid crystal panel 40 is to go up a plurality of glue frames 32 of coating at the silicon wafer substrate 11 ' that is formed with many a series of paintings pixel array 12, organize patterned circuit 14 and a plurality of connection pad 15 more.Then, in glue frame 32 region surrounded, form liquid crystal layer 34, and fit with a large-scale transparency carrier 21 ' that is manufactured with indium-tin oxide electrode 22 '.Afterwards, utilize cutter silicon wafer substrate 11 ' and large-scale transparency carrier 21 ' to be done the cutting of segment thickness.
Then please refer to Fig. 2 B, its illustrate into known silica-based liquid crystal panel at sliver (breaking) structural representation afterwards.Utilizing after cutter do the cutting of segment thickness to silicon wafer substrate 11 ' and large-scale transparency carrier 21 ', then the mode with sliver splits each silica-based liquid crystal panel 40.Because the periphery circuit region 11b of silicon substrate 11 must come out in design, electrically connect (bonding) on other carriers (carrier), by connection pad 15 as printed circuit board (PCB) (PCB) in order to follow-up.Therefore, silicon wafer substrate 11 ' can't be on same pedal line with the line of cut of large-scale transparency carrier 21 ', because the line of cut of silicon wafer substrate 10 ' and large-scale transparency carrier 21 ' is not on same pedal line, so the as easy as rolling off a log subtend substrate 20 that makes because of the application of force is improper weighs the patterned circuit 14 on the adjacent periphery circuit region 11b downwards wounded in the sliver process, and then causes problems such as silica-based liquid crystal panel 40 can't use.So, the making yield of silica-based liquid crystal panel 40 can't effectively be controlled, and causes cost of manufacture to improve.
