Abstract

A color filter substrate is provided, which includes a main body, and a touch flexible printed circuit (TFPC) and a black matrix arranged on the main body. The TFPC includes one or more light-transmissible regions, and an orthogonal projection of each light-transmissible region onto the main body does not overlap an orthogonal projection of the black matrix onto the main body.

First claim

What is claimed is:

wherein each light-transmissible region comprises a hollow region penetrating through the TFPC and a light-transmissible film covering merely the hollow region, the black matrix and the TFPC are arranged side-by-side in an identical layer in the color filter substrate, and the black matrix is in direct physical contact with the TFPC;
a first side surface of the black matrix is in direct physical contact with a second side surface of the TFPC, the first side surface of the black matrix is perpendicularly connected to a first main surface of the black matrix, the second side surface of the TFPC is perpendicularly connected to a second main surface of the TFPC, the first main surface of the black matrix surrounds a third main surface of the main body, and the hollow region penetrates through the second main surface.

2. The color filter substrate according to claim 1 , wherein the one or more light-transmissible regions comprise a plurality of light-transmissible regions spaced apart from each other.

3. The color filter substrate according to claim 2 , wherein the light-transmissible film is made of organic plastics.

4. The color filter substrate according to claim 1 , wherein the light-transmissible film is made of organic plastics.

5. The color filter substrate according to claim 4 , wherein the light-transmissible film is made of polyethylene terephthalate (PET) or polycarbonate (PC).

6. A touch panel, comprising an array substrate and the color filter substrate according to claim 1 arranged opposite to each other.

7. The touch panel according to claim 6 , wherein a region of the array substrate corresponding to the TFPC of the color filter substrate is a transparent region where no line is arranged.

8. The touch panel according to claim 6 , wherein the one or more light-transmissible regions comprise a plurality of light-transmissible regions spaced apart from each other.

9. The touch panel according to claim 8 , wherein the light-transmissible film is made of organic plastics.

10. The color filter substrate according to claim 1 , wherein the orthogonal projection of the black matrix onto the main body does not overlap an orthogonal projection of the TFPC onto the main body, to prevent the black matrix from shielding the TFPC.

11. A device for curing a liquid adhesive during a process of manufacturing a touch panel, comprising:
