Abstract

The present disclosure provides a glass layer for a display screen and a display screen, including: a glass layer body having a transverse direction and a longitudinal direction perpendicular to each other; a plurality of ribs spaced apart from each other and arranged on an upper surface of the glass layer body, a groove being formed between every two adjacent said ribs; a movable brush arranged on an outer surface of each of said ribs; a drive connection mechanism connecting with the movable brush for driving the movable brush to be reciprocated on the outer surface of said ribs.

First claim

What is claimed is:

1. A glass layer for a display screen, comprising:
a glass layer body having a transverse direction and a longitudinal direction perpendicular to each other;
a plurality of ribs spaced apart from each other and arranged on an upper surface of the glass layer body, a length of the rib is equal to a length of the glass layer body in the longitudinal direction, the plurality of ribs are arranged in parallel along the transverse direction of the glass layer body, each of said ribs extends along the longitudinal direction of the glass layer body from a top end of the glass layer body to a bottom end of the glass layer body, a groove being formed between every two adjacent said ribs, wherein both ends of the groove are drain outlets;
a movable brush arranged on an outer surface of each of said ribs; and
a drive mechanism connecting with the movable brush for driving the movable brush to be reciprocated on the outer surface of said ribs.

2. The glass layer for a display screen according to claim 1 , wherein the outer surface of the rib is a cylindrical surface.

3. The glass layer for a display screen according to claim 1 , wherein a cross-section shape of the rib is rectangular.

4. The glass layer for a display screen according to claim 1 , wherein the movable brush has a surface attached to the outer surface of the rib.

5. The glass layer for a display screen according to claim 1 , wherein a width W 1 of each of said grooves is greater than or equal to a width W 2 of the movable brush.

6. The glass layer for a display screen according to claim 1 , wherein the movable brush is made of transparent material.

7. The glass layer for a display screen according to claim 6 , wherein the movable brush is a polyelectrolyte byte.

8. The glass layer for a display screen according to claim 1 , wherein the movable brush has a surface attached to the outer surface of the rib.

9. The glass layer for a display screen according to claim 1 , wherein a width W 1 of each of said grooves is greater than or equal to a width W 2 of the movable brush.

10. The glass layer for a display screen according to claim 1 , wherein the movable brush is made of transparent material.

11. The glass layer for a display screen according to claim 6 , wherein the movable brush is a polyelectrolyte brush.

12. A display screen, wherein the display screen comprises a display panel and a glass layer for the display screen arranged on the display panel, the glass layer for the display screen comprises: a glass layer body having a transverse direction and a longitudinal direction perpendicular to each other; a plurality of ribs spaced apart from each other and arranged on an upper surface of the glass layer body, a length of the rib is equal to a length of the glass layer body in the longitudinal direction, the plurality of ribs are arranged in parallel along the transverse direction of the glass layer body, each of said ribs extends along the longitudinal direction of the glass layer body from a top end of the glass layer body to a bottom end of the glass layer body, a groove being formed between every two adjacent said ribs, wherein both ends of the groove are drain outlets; a movable brush arranged on an outer surface of each of said ribs; and a drive mechanism connecting with the movable brush for driving the movable brush to be reciprocated on the outer surface of said ribs.

13. The display screen according to claim 12 , wherein the display panel is attached to a lower surface of the glass layer.

14. The display screen according to claim 13 , wherein peripheries of the display panel and the glass layer are sealed.

15. The display screen according to claim 12 , wherein the movable brush has a surface attached to the outer surface of the rib.

16. The display screen according to claim 12 , further comprising a haze detecting device respectively electrically connecting the display panel and the drive mechanism, the haze detecting device detecting a number of blurry pixels of the display panel and determining whether to control the drive mechanism to drive the movable brush sliding according to the number of blurry pixels.
