Abstract

The present disclosure provides a cover, a display device, and a method for manufacturing the display device. By forming a first via hole in an electronic component disposing region when an optically clear adhesive is formed on the cover, via holes are formed because the optically clear adhesive cannot form in the electronic component disposing region. Thus, the optically clear adhesive does not have portions having different thicknesses, thereby preventing bubbles from forming in a blind hole region, and solving technical problems of the existing display device that the OCA has bubbles around the corresponding blind hole region, which affects photographing quality.

Claims (32)

1. A cover comprising a first via hole, wherein the first via hole is disposed in an electronic component disposing region corresponding to a location for disposing an electronic component, and the electronic component collects light through the first via hole,

wherein the cover comprises a transparent layer disposed in a display region corresponding to a display position, and the display region is disposed around the electronic component disposing region, and

wherein the cover further comprises an ink layer disposed in a light-blocking region, and a thickness of the ink layer is equal to a thickness of the transparent layer, wherein the light-blocking region is located between the display region and the electronic component disposing region.

2. The cover according to claim 1 , wherein a material of the transparent layer comprises transparent glass.

3. A display device, comprising:

a cover comprising a first via hole, wherein the first via hole is disposed in an electronic component disposing region corresponding to a location for disposing an electronic component, and the electronic component collects light through the first via hole;

an optically clear adhesive disposed under the cover and provided with a second via hole in the electronic component disposing region;

a polarizer disposed under the optically clear adhesive and provided with a third via hole in the electronic component disposing region; and

a display panel disposed under the polarizer;

wherein the first via hole, the second via hole, and the third via hole partially overlap each other,

wherein the cover comprises a transparent layer disposed in a display region corresponding to a display position, and the display region is disposed around the electronic component disposing region, and

wherein the cover further comprises an ink layer disposed in a light-blocking region, and a thickness of the ink layer is equal to a thickness of the transparent layer, wherein the light-blocking region is located between the display region and the electronic component disposing region.

4. The display device according to claim 3 , wherein the display device further comprises a protective layer disposed on a surface of the cover away from the display panel, and an area of a projection of the protective layer projecting on the display panel is equal to an area of the display panel.

5. The display device according to claim 3 , wherein the display panel is provided with a fourth via hole in the electronic component disposing region.

6. The display device according to claim 5 , wherein cross-sectional widths of the first via hole, the second via hole, and the third via hole are equal, and the cross-sectional width of the first via hole is greater than a cross-sectional width of the fourth via hole.

7. The display device according to claim 3 , wherein the display panel comprises a liquid crystal display panel or an organic light-emitting diode display panel.

8. The display device according to claim 3 , further comprising the electronic component, wherein the electronic component comprises a camera.

9. The display device according to claim 3 , wherein a material of the transparent layer comprises transparent glass.

10. A method for manufacturing a display device, comprising:

providing a display panel;

adhering a polarizer on the display panel, wherein the polarizer is provided with a third via hole in an electronic component disposing region corresponding to a location for disposing an electronic component;

adhering the polarizer and a cover by utilizing an optically clear adhesive, wherein the cover is provided with a first via hole in the electronic component disposing region, and the optically clear adhesive is provided with a second via hole in the electronic component disposing region,

wherein the cover comprises a transparent layer and an ink layer, the ink layer is disposed in a light-blocking region, the first via hole is provided on the ink layer in the electronic component disposing region, a thickness of the transparent layer is equal to a thickness of the ink layer, and the light-blocking region is disposed between a display region and the electronic component disposing region.

11. The method for manufacturing the display device according to claim 10 , wherein the step of adhering the polarizer and the cover by utilizing the optically clear adhesive comprises:

providing the cover;

providing the optically clear adhesive on the cover;

forming the first via hole in the electronic component disposing region on the cover and forming the second via hole on the optically clear adhesive, wherein a projection of the first via hole projecting on the display panel partially overlaps a projection of the second via hole projecting on the display panel; and

adhering the cover and the polarizer through the optically clear adhesive.

12. The method for manufacturing the display device according to claim 10 , wherein the step of adhering the polarizer and the cover by utilizing the optically clear adhesive comprises:

providing the cover with the first via hole in the electronic component disposing region;

providing the optically clear adhesive on the cover, wherein the optically clear adhesive is provided with the second via hole in the electronic component disposing region; and

adhering the cover and the polarizer through the optically clear adhesive.
