Housing 130 has one to be communicated with first surface 132 and second surface 134 opening 136 towards the first surface 132, of touch-control display panel 110 towards the second surface 134 and of wiring board 120.The opening 136 of housing 130 is such as positioned at below the 118a of viewing area.
Laser direct forming circuit 140 is formed on housing 130 in the mode of laser direct forming.Specifically, laser direct forming method (laser direct structuring, LDS) plastics of one gold doping metal catalyst are provided, afterwards, this plastics are irradiated with laser, in order to the metallic catalyst in activated plastics, then, the metallization line carrying out electroless plating (as chemical copper) is so that the part being optionally irradiated to laser at these plastics to form metallic circuit.
Laser direct forming circuit 140 extends to second surface 134 to be electrically connected the first corresponding connection pad 116 and the second connection pad 122 from first surface 132 through an inwall 136a of opening 136.In one embodiment, each laser direct forming circuit 140 has first end 142, the second end 144, is connected the connecting portion 146 of first end 142 and the second end 144 with one.First end 142 to be positioned on first surface 132 and to be electrically connected the first corresponding connection pad 116, the second end 144 to be positioned on second surface 134 and to be electrically connected the second corresponding connection pad 122, and connecting portion 146 extends to second surface 134 from first surface 132 through the inwall 136a of opening 136.
According to spirit of the present invention, as long as the forming position of laser direct forming circuit 140 can not be exposed housing 130 and be seen by (touch control display apparatus 100) user, laser direct forming circuit 140 can be formed at the optional position of housing 130 to reach effect of electric connection first connection pad 116 and the second connection pad 122.
It should be noted that, circuit (laser direct forming circuit 140) is directly formed on housing 130 to connect touch-control display panel 110 and wiring board 120 by the present embodiment, therefore, existing flexible circuit board can be used, and the non-display area 118b of touch-control display panel 110 only need configure connection pad (the first connection pad 116), and existing perimeter circuit need not be configured, therefore, significantly can reduce the width W (as shown in Figure 1B) of non-display area 118b, and then increase the size of viewing area 118a.
Continue referring to Figure 1A, Fig. 1 C and Fig. 1 E, in one embodiment, housing 130 comprises an a flat part 138a and outer frame 138b.Flat part 138a is sandwiched between touch-control display panel 110 and wiring board 120, and laser direct forming circuit 140 is arranged on flat part 138a.Outer frame 138b connects the outer rim of flat part 138a and covers outer wall S1, S2 of touch-control display panel 110 and wiring board 120.In other embodiments, according to practical wiring demand, laser direct forming circuit 140 can be arranged on flat part 138a and outer frame 138b.
In one embodiment, can multiple soft conductor 150 be configured between the first connection pad 116 and corresponding laser direct forming circuit 140 respectively, to be electrically connected the first connection pad 116 and corresponding laser direct forming circuit 140.Soft conductor 150 is such as conducting foam, conductive rubber or other soft conductive materials be applicable to.
In one embodiment, multiple elastic conductor can be configured at respectively between the second connection pad 122 and corresponding laser direct forming circuit 140, to be electrically connected the second connection pad 122 and corresponding laser direct forming circuit 140.Elastic conductor is such as electroconductive elastic sheet 162 or spring needle 164.
It should be noted that, although be illustrated as the touch control display apparatus 100 using electroconductive elastic sheet 162 and spring needle 164 in the present embodiment simultaneously, but in other embodiments, also can only use electroconductive elastic sheet 162 (or spring needle 164) to be electrically connected the second connection pad 122 and laser direct forming circuit 140.
In one embodiment, can an adhesive coating 170 be formed between touch-control display panel 110 and housing 130, to engage touch-control display panel 110 and housing 130.The material of adhesive coating 170 can be any colloid being suitable for adhesion touch-control display panel 110 and housing 130.In addition, also an adhesive coating 180 can be formed between housing 130 and wiring board 120, with engage 130 and wiring board 120.The material of adhesive coating 180 can be identical or be different from the material of adhesive coating 170.
Fig. 2 A is the explosive view of the touch control display apparatus of another embodiment of the present invention.Fig. 2 B is the upward view of the touch-control display panel of Fig. 2 A.Fig. 2 C is the upward view of the housing of Fig. 2 A.
Referring to Fig. 2 A, Fig. 2 B and Fig. 2 C, the touch control display apparatus 200 of the present embodiment is similar in appearance to the touch control display apparatus 100 of Figure 1A, and both difference parts are that the second connection pad 122 of touch control display apparatus 200 is positioned at the side of viewing area 118a.Also therefore, the laser direct forming circuit 240 of the present embodiment is for being electrically connected at the wire laying mode need between the first connection pad 116 and the second corresponding connection pad 122 with the laser direct forming circuit 140 being different from Figure 1A.
Specifically, in the present embodiment, the first end 242 of laser direct forming circuit 240 is positioned on first surface 132 and position and corresponds to the first connection pad 116, that is first end 242 is arranged around viewing area 118a.The second end 244 of laser direct forming circuit 240 is positioned on second surface 134 and position and corresponds to the second connection pad 122, that is the second end 244 is positioned at the side of viewing area 118a.The connecting portion 246 of laser direct forming circuit 240 is connected between first end 242 and corresponding the second end 244.
In the present embodiment, laser direct forming circuit 240 sequentially can extend to second surface 134 by first surface 132 through the inwall 136a of opening 136, or laser straight forming circuit 240 can sequentially by first surface 132, outer frame 138b inwall 138c, first surface 132, extend to second surface 134 through the inwall 136a of opening 136.
In sum, laser direct forming circuit is formed on housing to connect touch-control display panel and wiring board by touch control display apparatus of the present invention, therefore, existing flexible circuit board can not be used to connect touch-control display panel and wiring board, and the non-display area of touch-control display panel of the present invention only need configure connection pad, and must not configure existing perimeter circuit, therefore, significantly can reduce the width of non-display area, and then increase the size of viewing area.
Though the present invention with preferred embodiment openly as above; so itself and be not used to limit protection scope of the present invention; any the technical staff in the technical field; without departing from the spirit and scope of the present invention; when doing a little change and retouching, therefore protection scope of the present invention is as the criterion with claims.
