Specific embodiment

Flexible printed wiring board in a kind of display equipment of the embodiment of the present invention is extended to metal routing by through-hole The both ends of flexible base plate and it is electrically connected pin, to compress the bending space on the inside of flexible printed wiring board, so that display equipment Shield accounting screen with height.

According to fig. 2, a kind of display equipment 200 includes backlight module 201, first substrate 202, thin-film transistor array base-plate 203, colored filter 204, the second substrate 205, control circuit board 206 and flexible printed wiring board 207.Preferably, display is set Standby 200 be liquid crystal display.Specifically, first substrate 202 is arranged on backlight module 201, thin-film transistor array base-plate 203 are arranged on first substrate 201, and the second substrate 205 is arranged on colored filter 204, control circuit board 206 and colored filter Mating plate 204 is arranged on thin-film transistor array base-plate 203, and flexible printed wiring board 207 is arranged in thin film transistor (TFT) array base On plate 203, wherein first substrate 202 and the second substrate 205 are glass substrates and flexible printed wiring board 207 includes soft Substrate 208, through-hole 209, pin 210 and metal routing 211.Between having between colored filter 204 and control circuit board 206 Also there is gap between gap and control circuit board 206 and flexible printed wiring board 207.In addition, display equipment 200 further includes Anisotropic conducting membrance 212, anisotropic conducting membrance 212 coats the bottom and side of pin 210, and flexible base plate is arranged in pin 210 208 inside bottom.Therefore, it is no longer necessary to which the side of gel protection pin 210 is not needed in the inside of flexible base plate 208 yet Protective layer is set.Furthermore through-hole 209 runs through flexible base plate 208, and is the row of missing one another through the through-hole 209 of flexible base plate 208 Column.Metal routing 211 extends to the outside both ends of flexible base plate 208 by through-hole and is electrically connected pin 210, so that pin 210 can be electrically connected by metal routing 211 and control circuit board 206.The inside of through-hole 209 plates metal layer, it is preferable that The inside of through-hole 209 plates layers of copper, it is highly preferred that the aperture of through-hole 209 is less than 0.1 millimeter.Furthermore, equipment is shown 200 further include protective layer 213, and protective layer 213 is completely covered from the metal at the both ends that through-hole 209 extends to flexible base plate 208 The outside of flexible base plate 208 is also completely covered in line 211 and protective layer 213.Compared to Fig. 1, the flexible printer circuit of Fig. 2 is also It can further bend inwardly, and then compress the bending space on the inside of flexible printed wiring board.

According to Fig. 3, due to being to make through-hole 209 directly on flexible base plate 208, and partial through holes 209 can overlap each other And can not be formed and effectively be overlayed, to influence to overlay effect problem.Therefore setting runs through flexible base plate on flexible base plate 208 208 through-hole 209, through-hole 209 are the arrangements that misses one another.In addition, the shape of flexible base plate 208 can be polygon, and soft Substrate 208 is also the arrangement that misses one another.

It is the through-hole 309 that another implementation setting on flexible base plate 308 runs through flexible base plate 308, through-hole 309 according to Fig. 4 It is the arrangement that misses one another.Fig. 4 is from Fig. 3's the difference is that the shape of flexible base plate is different.

The flexible printed wiring board of the embodiment of the present invention no longer needs additionally to coat the side of gel protection pin, is also not required to Protective layer is set in the inside of flexible base plate, moreover it is possible to which metal routing is extended to both ends and the electrical property of flexible base plate by through-hole Pin is connected, therefore can further compress the bending space on the inside of flexible printed wiring board, so that display equipment is accounted for Gao Ping Compare screen.

Although the present invention is described in conjunction with its specific embodiment, it should be understood that many substitutions, modification and variation pair It will be apparent in those skilled in the art.Therefore, it is intended to comprising falling into the scope of the appended claims Interior all substitutions, modification and variation.
