Abstract

A hole-punch screen includes a light-transmitting cover, a polarizer, and a glass component, where the polarizer is attached to the light-transmitting cover, the polarizer is provided with a first through hole, and the first through hole is filled with optical clear glue; and the glass component is attached to the polarizer so that the polarizer is located between the light-transmitting cover and the glass component, and the glass component is provided with a second through hole at a position corresponding to the first through hole.

First claim

What is claimed is:

1. A hole-punch screen, comprising:
a light-transmitting cover;
a polarizer, wherein the polarizer is attached to the light-transmitting cover, the polarizer is provided with a first through hole, and the first through hole is filled with optical clear glue; and
a glass component, wherein the glass component is attached to the polarizer, the polarizer is located between the light-transmitting cover and the glass component, and the glass component is provided with a second through hole at a position corresponding to the first through hole;
wherein the glass component comprises:
upper glass, wherein the upper glass is attached to the polarizer, the upper glass is provided with a first recess at a position corresponding to the first through hole, and the first recess is located on a first side of the upper glass facing away from the polarizer;
lower glass, wherein the lower glass is attached to the upper glass via a frame adhesive;
support columns located between the upper glass and the lower glass; and
foam, wherein the foam is located on a side of the lower glass facing away from the upper glass, and the second through hole is located in the foam;
wherein the lower glass is provided with a second recess at a position corresponding to the first recess, and the second recess is located on a second side of the lower glass facing the upper glass;
wherein the upper glass is further provided with a first groove at a position corresponding to the first through hole, and the first groove is located on a third side of the upper glass facing the polarizer, where the first side of the upper glass and the third side of the upper glass are opposite sides of the upper glass; wherein a first recess bottom of the first recess has an arc surface, and the first recess bottom has a same shape as the first groove;
wherein the lower glass is further provided with a second groove at a position corresponding to the first recess, and the second recess is located on a fourth side of the lower glass facing away from the upper glass, where the second side of the lower glass and the fourth side of the lower glass are opposite sides of the upper glass; wherein a second recess bottom of the second recess has an arc surface, and the second recess bottom has a same shape as the second groove.

2. The hole-punch screen according to claim 1 , wherein an outer side of the arc surface faces towards the first through hole.

3. The hole-punch screen according to claim 2 , wherein a cross section of the first recess is round, and a diameter of the first recess is equal to a diameter of the first through hole.

4. The hole-punch screen according to claim 1 , wherein a contact area between the support columns and the upper glass is less than a contact area between the support columns and the lower glass.

5. The hole-punch screen according to claim 4 , wherein a cross-sectional area of the support columns gradually increases in a direction from the upper glass toward the lower glass.

6. The hole-punch screen according to claim 1 , wherein a volume of the optical clear glue is greater than a capacity of the first through hole.

7. The hole-punch screen according to claim 1 , wherein the polarizer is attached to the light-transmitting cover via an optical clear double-sided adhesive.

8. An electronic device, comprising a hole-punch screen, wherein the hole-punch screen comprises:
a light-transmitting cover;
a polarizer, wherein the polarizer is attached to the light-transmitting cover, the polarizer is provided with a first through hole, and the first through hole is filled with optical clear glue; and
a glass component, wherein the glass component is attached to the polarizer, the polarizer is located between the light-transmitting cover and the glass component, and the glass component is provided with a second through hole at a position corresponding to the first through hole;
wherein the glass component comprises:
upper glass, wherein the upper glass is attached to the polarizer, the upper glass is provided with a first recess at a position corresponding to the first through hole, and the first recess is located on a first side of the upper glass facing away from the polarizer;
lower glass, wherein the lower glass is attached to the upper glass via a frame adhesive;
support columns located between the upper glass and the lower glass; and
foam, wherein the foam is located on a side of the lower glass facing away from the upper glass, and the second through hole is located in the foam;
wherein the lower glass is provided with a second recess at a position corresponding to the first recess, and the second recess is located on a second side of the lower glass facing the upper glass;
wherein the upper glass is further provided with a first groove at a position corresponding to the first through hole, and the first groove is located on a third side of the upper glass facing the polarizer, where the first side of the upper glass and the third side of the upper glass are opposite sides of the upper glass; wherein a first recess bottom of the first recess has an arc surface, and the first recess bottom has a same shape as the first groove;
wherein the lower glass is further provided with a second groove at a position corresponding to the first recess, and the second recess is located on a fourth side of the lower glass facing away from the upper glass, where the second side of the lower glass and the fourth side of the lower glass are opposite sides of the upper glass; wherein a second recess bottom of the second recess has an arc surface, and the second recess bottom has a same shape as the second groove.

9. The electronic device according to claim 8 , wherein an outer side of the arc surface faces towards the first through hole.

10. The electronic device according to claim 9 , wherein a cross section of the first recess is round, and a diameter of the first recess is equal to a diameter of the first through hole.

11. The electronic device according to claim 8 , wherein a contact area between the support columns and the upper glass is less than a contact area between the support columns and the lower glass.

12. The electronic device according to claim 11 , wherein a cross-sectional area of the support columns gradually increases in a direction from the upper glass toward the lower glass.

13. The electronic device according to claim 8 , wherein a volume of the optical clear glue is greater than a capacity of the first through hole.
