Abstract

A display panel includes a cover plate, an array substrate, and an opposite substrate. The array substrate is disposed between the cover plate and the opposite substrate. An edge of a surface of the array substrate away from the cover plate includes a bonding region for bonding at least one circuit, and a portion of a surface of the array substrate close to the cover plate corresponding to the bonding region is fixedly connected to the cover plate. The opposite substrate is assembled face to face with the array substrate.

First claim

What is claimed is:

1. A display panel, comprising:
a cover plate;
an array substrate disposed on a side of the cover plate, wherein an edge of a surface of the array substrate away from the cover plate includes a bonding region for bonding at least one circuit, and a portion of a surface of the array substrate close to the cover plate corresponding to the bonding region is fixedly connected to the cover plate;
an opposite substrate disposed on a side of the array substrate away from the cover plate, wherein the opposite substrate is assembled with the array substrate;
at least one circuit bonded to the bonding region of the array substrate, wherein one of the at least one circuit protrudes from the edge of the surface of the array substrate away from the cover plate;
a Kapton tape for bonding the one of the at least one circuit to an end portion of the array substrate having the bonding region, wherein the Kapton tape is configured to be coated in lines; and
a glue protection layer coated on the bonding region of the array substrate, wherein the glue protection layer does not cover or partially covers the at least one circuit.

2. The display panel according to claim 1 , wherein the opposite substrate is a color film substrate, and the color film substrate does not cover the bonding region.

3. The display panel according to claim 2 , wherein a portion of the surface of the array substrate close to the cover plate corresponding to the color film substrate is fixedly connected to the cover plate.

4. The display panel according to claim 3 , further comprising:
a first polarizer disposed on a side of the array substrate close to the cover plate, and
an optically clear adhesive layer disposed between the first polarizer and the cover plate, and the optically clear adhesive layer being used for bonding the first polarizer to the cover plate.

5. The display panel according to claim 4 , wherein the first polarizer completely covers or partially covers the surface of the array substrate close to the cover plate.

6. The display panel according to claim 5 , wherein the first optically clear adhesive layer completely covers or partially covers a surface of the first polarizer away from the array substrate.

7. The display panel according to claim 6 , further comprising:
a liquid crystal layer disposed between the array substrate and the color film substrate; and
a second polarizer disposed on a side of the color film substrate away from the array substrate.

8. The display panel according to claim 3 , further comprising an optically clear adhesive layer disposed between the array substrate and the cover plate, and the optically clear adhesive layer being used for bonding the surface of the array substrate close to the cover plate to the cover plate.

9. The display panel according to claim 8 , wherein the optically clear adhesive layer completely covers or partially covers the surface of the array substrate close to the cover plate.

10. A method of manufacturing the display panel according to claim 1 , comprising:
providing an array substrate, an edge of a surface of the array substrate including a bonding region;
placing a cover plate on another surface of the array substrate opposite to the bonding region, and fixedly connecting a portion of the another surface of the array substrate corresponding to the bonding region to the cover plate;
providing an opposite substrate, and assembling the opposite substrate with the array substrate;
bonding at least one circuit to an end portion of the array substrate having the bonding region by a Kapton tape, wherein one of the at least one circuit protrudes from the edge of the surface of the array substrate away from the cover plate, and the Kapton tape is configured to be coated in lines; and
coating a glue protection layer on a portion of a surface of the bonding region not covered by the at least one circuit; or, coating a glue protection layer on a portion of the at least one circuit and the portion of the surface of the bonding region not covered by the at least one circuit.

11. The method of manufacturing the display panel according to claim 10 , wherein assembling the opposite substrate with the array substrate, includes: placing the opposite substrate on a side of the array substrate including the bonding region in a way that the opposite substrate does not cover the bonding region after being assembled.

12. The method of manufacturing the display panel according to claim 11 , wherein placing the cover plate on another surface of the array substrate opposite to the bonding region, includes:
coating an optically clear adhesive layer on the another surface of the array substrate opposite to the bonding region, so as to bond the array substrate to the cover plate via the optically clear adhesive layer;
or, attaching a first polarizer to the another surface of the array substrate opposite to the bonding region, and coating an optically clear adhesive layer on a surface of the first polarizer away from the array substrate, so as to bond the array substrate to the cover plate via the optically clear adhesive layer.

13. A display device, comprising:
the display panel according to claim 1 ; and
a backlight module disposed on a back side of the display panel that is opposite to a display side thereof.
