Embodiment
Below by accompanying drawing, several preferred embodiments of the present invention to be done to explain.In accompanying drawing, mentioned same numeral means same or similar element.
Fig. 2 A is the perspective exploded view of a kind of display module of one embodiment of the invention.Fig. 2 B is the schematic perspective view of display module after assembling of Fig. 2 A.Please also refer to Fig. 2 A and Fig. 2 B, display module 200 comprises a substrate 210, a flexible circuit board 220, a silica-based liquid crystal panel 230 and a face cap 240.
Specifically, substrate 210 can be in order to support silica-based liquid crystal panel 230 and other elements.The surface of substrate 210 has a bonding region 212, and wherein bonding region 212 can be the part on surface of substrate 210 or a lip-deep projection of substrate 210.In addition, bonding region 212 can be smooth or coarse.In the present embodiment, the material of substrate 210 is for example aluminium, and substrate 210 is for example a heating radiator.
Silica-based liquid crystal panel 230 has a lower surface 230b and a upper surface 230a with respect to lower surface 230b.As shown in Fig. 2 A, silica-based liquid crystal panel 230 has one and is positioned at the viewing area 232 of upper surface 230a and the non-display area around viewing area 232.In addition, the lower surface 230b of silica-based liquid crystal panel 230 is fixed in the bonding region 212 of the substrate 210 that opening 222 exposes, and is electrically connected to flexible circuit board 220.In the present embodiment, adhesive coating 250 is for example a thermal conductivity adhesive tape, in order to be fixed in the silica-based liquid crystal panel 230 on substrate 210, to reach the effect of heat radiation.Yet the present invention can all can be used as the cohesive material of adhesive coating 250 such as not as limit.
Certainly, in other embodiments, flexible circuit board 220 also can not have opening 222, and silica-based liquid crystal panel 230 can be fixed on flexible circuit board 220 by adhesive coating 250.Therefore, the structure of the flexible circuit board 220 shown in Fig. 2 A and Fig. 2 B is only for illustrating, and non-limiting the present invention.In addition, in the present embodiment, silica-based liquid crystal panel 230 can be electrically connected to flexible printed circuit 220 by many routings 260.Display module 200 comprises that more one is positioned at the protection glue 270 on flexible circuit board 220, in order to cover these routings 260.The protection glue 270 effect be the protection these routings 260 with avoid these routings 260 impaired with make moist.
Because face cap 240 is disposed on silica-based liquid crystal panel 230, and have the opening 242 of demonstration, come out from the demonstration opening 242 of face cap 240 exactly in viewing area 232.So the present embodiment can solve the problem that in the prior art silica-based liquid crystal panel 230 is assembled to the cumulative limit that produces on substrate 210 effectively.
In addition, in the present embodiment, face cap 240 has a pair of pilot hole 244, and silica-based liquid crystal panel 230 has a pair of telltale mark 234 that is positioned at non-display area.Because face cap 240 can be by being for example that the sticker that adhesive tape or other are fit to is directly fixed on silica-based liquid crystal panel 230, thus this to pilot hole 244 can distinguish auto-alignment this to telltale mark 234.In addition, face cap 240 more comprises a fixed orifice 246, and wherein fixed orifice 246 can be affixed with a light engine, in order to lower cumulative limit.In the present embodiment, the material of face cap 240 can be iron and steel or engineering plastic, and in fact, adopts nonreflective material better.
In brief, in the present embodiment, face cap 240 can be directly fixed on silica-based liquid crystal panel 230, and face cap 240 can directly be fixed in light engine, so can effectively reduce the cumulative limit when assembling from silica-based liquid crystal panel 230 to light engine.In addition, when the size of face cap 240 during corresponding to silica-based liquid crystal panel 230 big or small, display module 200 occupied space can be reduced.In addition, face cap 240 can be used as light shield, in order to cover non-display area.
Fig. 3 A is the schematic perspective view of a kind of display module of another embodiment of the present invention.Fig. 3 B is the diagrammatic cross-section of the display module of Fig. 3 A.Please also refer to Fig. 3 A and Fig. 3 B, display module 200 ' is roughly the same with the display module 200 that Fig. 2 B illustrates, and difference only is in Fig. 3 A and Fig. 3 B, two ends 240a ', the 240b ' of face cap 240 ' are bent to substrate 210 downwards, and be fixed on substrate 210 by a sticker 280 ', wherein sticker 280 ' can increase the bond strength between face cap 240 ' and substrate 210.
Specifically, in the present embodiment, face cap two ends 240a ', 240b ' are bent to the height of substrate 210 downwards less than the height of silica-based liquid crystal panel 230.In addition, face cap 240 ' more comprises two fixed sidewalls 244 ', 246 ' that are connected to face cap 240 ' both side edges, and these fixed sidewalls 244 ', 246 ' can and be used to connect light engine in order to the structural strength that increases face cap 240 '.Moreover these fixed sidewalls 244 ', 246 ' also can be by screw or sticker and affixed with light engine.
Should be noted that at this, above-mentioned face cap 240,240 ' also can be applied to the display module of other kinds.In the embodiment that other do not illustrate, display module comprises a substrate, a silica-based liquid crystal panel and a face cap.It is similar that the arrangement mode of these elements and Fig. 2 A illustrate, therefore do not repeat them here.The difference of the display module 200 of display module and Fig. 2 A is: substrate has a circuit, and silica-based liquid crystal panel need not be disposed at flexible circuit board.Specifically, substrate is for example ceramic material or printed circuit board (PCB), and substrate can be electrically connected to control circuit by connector.For example, control circuit is configurable in the below of substrate, and silica-based liquid crystal panel can be electrically connected to control circuit by substrate.In other words, silica-based liquid crystal panel can possess flexible circuit board and be electrically connected to substrate, can effectively reduce the volume of display module.
In sum, display module of the present invention is lived the viewing area of silica-based liquid crystal panel and covers parasitic light with frame by being disposed at the face cap on silica-based liquid crystal panel.Because the face cap that is configured on silica-based liquid crystal panel has the demonstration opening, come out from the demonstration opening of face cap exactly in the viewing area, therefore be compared to prior art, the present invention can effectively reduce silica-based liquid crystal panel and be assembled to cumulative limit on substrate.
Although disclosed the present invention in conjunction with above embodiment; yet it is not to limit the present invention; be familiar with this operator in the field under any; without departing from the spirit and scope of the present invention; can do a little change and retouching, thus protection scope of the present invention should with enclosed claim was defined is as the criterion.
