Abstract

A display includes at least an array substrate, and the array substrate has a drive circuit layer. At least one first notch is provided on an outer edge of a lead-out side of the array substrate, and a first conductor is disposed in each first notch. A first end of the first conductor is in contact with a lead end of the drive circuit layer, and a second end of the first conductor extends along the first notch to a back side of the array substrate.

First claim

a first end in contact with a lead end of the drive circuit layer; and
a second end extending along the first notch to a back side of the array substrate and coupling to the main control board;

an opposite substrate opposite to the array substrate, wherein a second notch is provided on an outer edge of the opposite substrate that corresponds to the lead-out side of the array substrate;
a touch circuit disposed on the opposite substrate; and
a second conductor disposed in the second notch and comprising:
a third end in contact with a lead end of the touch circuit; and
a fourth end extending along the second notch to the array substrate and electrically coupling to the first end of the first conductor,

wherein the touch circuit is electrically coupled to the main control board using the first conductor and the second conductor, and
wherein inner walls of the first notch and the second notch are non-closed arcuate walls.

2. The display of claim 1 , wherein the first notch and the second notch are semi-circular holes penetrating through a front surface and a rear surface of the array substrate.

3. The display of claim 1 , wherein the first notch and the second notch are semi-conical holes with openings that gradually decrease from top to bottom.

4. The display of claim 3 , wherein a first outer side surface of the first conductor disposed in the first notch does not extend beyond a first side surface of the first notch, and wherein a second outer side surface of the second conductor disposed in the second notch does not extend beyond a second side surface of the second notch.

5. The display of claim 1 , wherein the first conductor and the second conductor are made of conductive materials that fill the first notch and the second notch.

6. The display of claim 1 , wherein the first conductor and the second conductor are conductive wires.
