Description

Cover plate and electronic device using the same

The present invention relates to a cover and an electronic device using the same.

In the existing electronic device, a functional panel such as a display panel or a touch panel is attached to the cover by an adhesive layer. However, the cover sheet is usually printed with an ink layer for light shielding. Since the ink layer is usually relatively thick, the adhesive layer tends to be insufficiently adhered at the stepped structure formed at the edge of the ink layer to easily cause bubbles, thereby affecting the production yield of the electronic device.

In view of this, it is necessary to provide a cover plate which can reduce the defects caused by the conforming air bubbles and an electronic device using the same.

A cover plate includes a display portion and a non-display portion. At least one button pattern is disposed on the non-display portion. The display portion includes a boundary line adjacent to the non-display portion. The non-display portion includes a boundary line surrounding the boundary line, a first coating region defined by the boundary line and the boundary line, and a second coating region covering at least the button pattern. The non-display portion is coated with an ink layer. The thickness of the ink layer corresponding to the second coating zone portion is greater than the thickness of the portion corresponding to the first coating zone.

An electronic device includes a cover plate and a functional module disposed on the cover plate. The cover plate includes a display portion and a non-display portion. At least one button pattern is disposed on the non-display portion. The display portion includes a boundary line adjacent to the non-display portion. The non-display portion includes a boundary line surrounding the boundary line, a first coating region defined by the boundary line and the boundary line, and a second coating region covering at least the button pattern. The non-display portion is coated with an ink layer. The thickness of the ink layer corresponding to the second coating zone portion is greater than the thickness of the portion corresponding to the first coating zone. The functional module is attached to the cover by an adhesive layer.

Compared with the prior art, the first coating zone of the cover plate provided by the invention is only coated with a single layer of ink, so the interface between the display portion and the non-display portion and the boundary between the first coating region and the second coating region are due to the ink layer. The step difference formed is small, so that the adhesive layer can be sufficiently adhered to prevent the generation of bubbles. The double-layer ink disposed on the second coating zone also satisfies the shading requirement of the high-brightness backlight of the button pattern.

FIG. 5 is a cross-sectional view of an electronic device according to a third embodiment of the present invention.

As shown in FIG. 1 to FIG. 3, the electronic device 1 according to the first embodiment of the present invention includes a cover 10 and a functional module 12 attached to the surface of the cover 10. The cover 10 includes a display portion 100 and a non-display portion 102. At least one button pattern 1021 is disposed on the non-display portion 102. The display portion includes a boundary line 1023 adjacent to the non-display portion. The non-display portion 102 includes a boundary line 1024 surrounding the boundary line 1023, a first coating region 1022 defined by the boundary line 1023 and the boundary line 1024, and a second coating region 1020 covering at least the button pattern 1021. . The electronic device 1 is provided with an ink layer 103 on the surface of the cover 10 for attaching the functional module 12. The ink layer 103 is provided corresponding to the non-display portion 102 of the cover 10. The thickness of the ink layer 103 corresponding to the portion of the second coating zone 1020 is greater than the thickness of the portion corresponding to the first coating zone 1022. In this embodiment, the portion of the ink layer 103 corresponding to the second coating region 1020 is a two-layer ink structure, and the portion corresponding to the first coating region 1022 is a single-layer ink structure. The functional module 12 is attached to the cover 10 by an adhesive layer and laminated with at least a portion of the ink layer 103. The electronic device 1 can be, but is not limited to, a mobile phone, a tablet or a display.

The cover 10 is an outer cover of the electronic device 1 for protecting the functional module 12 inside the electronic device 1 and embodying the design of the electronic device 1 by a pattern disposed thereon. The cover 10 is at least partially made of a transparent material such as plastic or glass. The display unit 100 is a light-transmissive area on the cover 10 that is not coated with the ink 103. The display unit 100 is configured to provide a window for the user to view the display of the functional module 12 corresponding to the display unit 100. Image. The non-display portion 102 is a light-shielding region on which the ink sheet 103 is coated on the cover plate 10. The boundary line 1023 includes a pair of mutually parallel long sides 1026 extending in the longitudinal direction of the display portion 100 and a pair of mutually parallel short sides 1025 perpendicularly connected to the long sides 1026. The boundary line 1024 includes a pair of side edges 1027 corresponding to the long sides 1026, an upper edge 1028 corresponding to one of the short sides 1025, and a lower edge 1029 opposite the other short side 1025. The distance between the lower edge 1029 and the corresponding short side 1025 is much smaller than the distance between the upper edge 1028 and the corresponding short side 1025. That is to say, the display unit 100 is disposed close to the lower edge 1029. The second coating zone 1020 is disposed between the lower edge 1029 and the edge of the cover 10 on the same side. The second coating zone 1020 empties the plurality of button patterns 1021 on the double layer ink 103. In the present embodiment, the cover 10 is substantially rectangular. The display portion 100 is rectangular and located in the middle of the cover 10. The length extension direction of the display portion 100 coincides with the length extension direction of the cover plate 10.

Since the first coating region 1022 is only coated with the single layer ink 103, the interface between the display portion 100 and the non-display portion 102 and the first coating region 1022 and the second coating region 1020 are due to the relative thickness of the ink layer 103. The ink layer 103 formed by the thinner step has a small step difference, so that the adhesive layer can be sufficiently adhered to prevent the generation of bubbles. The ink layer 103 disposed on the second coating zone 1020 is relatively thick and also satisfies the shading requirement of the high-brightness backlight of the button pattern 1021.

In the embodiment, the functional module 12 includes a touch panel 120 and/or a polarizer 122. The polarizer 122 and/or the touch panel 120 are attached to the side of the cover 10 on which the ink layer 103 is printed by an optical adhesive 123 and an explosion-proof film 121.

As shown in FIG. 4, the structure of the electronic device 2 provided by the second embodiment of the present invention is substantially the same as that of the electronic device 1 provided by the first embodiment, except that the functional module 12 includes a pair of transparent conductive Film 226 and/or polarizer 222. A pair of optical adhesives 223 are interposed between the pair of transparent conductive films 226 to form a capacitive touch structure. The pair of transparent conductive films 226 and the polarizer 222 are attached to the side of the cover 20 on which the ink 203 is printed by another layer of optical adhesive 223.

As shown in FIG. 5, the structure of the electronic device 3 provided by the third embodiment of the present invention is basically the same as that of the electronic device 1 provided by the first embodiment, except that the functional module 32 includes a pair of transparent conductive The film 326 and a substrate 327. The pair of transparent conductive films 326 are bonded to each other to form a resistive touch structure and are attached to the substrate 327 by a layer of optical adhesive 323. The substrate 327 and the pair of transparent conductive films 326 are attached to the side of the cap plate 30 on which the ink 303 is printed by a layer of optical adhesive 323.
