Abstract

A conductive substrate comprises a substrate, a plurality of conductive patterns, and a plurality of optical compensation patterns. The conductive patterns extend along a first direction and are sequentially disposed on the substrate along a second direction. The optical compensation patterns are staggered from the conductive patterns along the second direction on the substrate. An edge of at least one of the conductive patterns extending along the first direction has a plurality of conductive protrusions, and an edge of at least one of the optical compensation patterns extending along the first direction has a plurality of optical compensation protrusions. A touch display device is also disclosed.

Claims (26)

a first conductive substrate including a first substrate, a plurality of first conductive patterns and a plurality of optical compensation patterns, wherein the first conductive patterns extend along a first direction and are sequentially disposed on the first substrate along a second direction, the optical compensation patterns are staggered from the first conductive patterns along the second direction on the first substrate, an edge of at least one of the first conductive patterns extending along the first direction has a plurality of conductive protrusions, and an edge of at least one of the optical compensation patterns extending along the first direction has a plurality of optical compensation protrusions;

a substrate disposed opposite the first conductive substrate;

a liquid crystal layer disposed between the first conductive substrate and the substrate; and

a color filter layer disposed between the first conductive substrate and the liquid crystal layer and having a blocking structure, a vertical projection of the blocking structure overlapping at least a part of the optical compensation patterns.

2. The touch display device as recited in claim 1 , wherein the substrate is a second conductive substrate including a second substrate and a plurality of second conductive patterns which extend along the second direction and are sequentially disposed on the second substrate along the first direction.

3. The touch display device as recited in claim 2 , further comprising:

a signal processing module electrically connected to the first conductive patterns and the second conductive patterns;

a first polarizing structure disposed on the first conductive substrate;

a second polarizing structure disposed on a side of the second conductive substrate away from the liquid crystal layer; and

a backlight module disposed on a side of the second polarizing structure away from the second conductive substrate.

4. The touch display device as recited in claim 3 , wherein the first polarizing structure includes an anti-electrostatic material.

5. The touch display device as recited in claim 3 , further comprising:

a frame having an accommodating space for accommodating the first conductive substrate, the second conductive substrate, the liquid crystal layer, the signal processing module, the first polarizing structure, the color filter layer, the second polarizing structure, and the backlight module.

6. The touch display device as recited in claim 3 , wherein the first polarizing structure further comprises:

an adhesive film disposed on the first conductive substrate;

a polarizing film disposed on the adhesive film; and

a protective film disposed on the polarizing film.

7. The touch display device as recited in claim 1 , wherein the first conductive patterns are a plurality of transmitter electrodes and a plurality of receiver electrodes, respectively.

8. The touch display device as recited in claim 7 , wherein the optical compensation patterns are surrounded by the transmitter electrodes.

9. The touch display device as recited in claim 1 , wherein the adjacent conductive protrusions and the optical compensation protrusions are staggered from each other.

10. The touch display device as recited in claim 1 , wherein the adjacent conductive protrusions and the optical compensation protrusions are staggered from each other in the way of a zigzag or in the way of convexes and concaves.

11. The touch display device as recited in claim 1 , wherein a width of at least one of the first conductive patterns is between 300 microns and 1000 microns, and a width of at least one of the optical compensation patterns is between 500 microns and 2000 microns.

12. The touch display device as recited in claim 1 , wherein an interval formed between the adjacent first conductive pattern and optical compensation pattern is between 1 micron and 10 microns.
