Abstract

A touch member and a display are provided. The touch member includes: a first substrate ( 100 ), a number of touch electrodes, and a number of signal lines. The first substrate includes at least one bendable bending area. The touch electrodes are disposed on at least one surface of the first substrate ( 100 ). At least some of the touch electrodes are separated into a number of disconnected touch sub-electrodes by the bending region. And each of the touch sub-electrodes is driven by a signal line.

First claim

What is claimed is:

1. A touch member, comprising:
a first substrate, comprising at least one bendable bending region; and
a plurality of strip-shaped touch electrodes disposed on at least one surface of the first substrate;
wherein at least some of the plurality of strip-shaped touch electrodes are separated into a plurality of disconnected strip-shaped touch sub-electrodes by the bending region, and each of the strip-shaped touch sub-electrodes is driven by one respective signal line,
wherein the plurality of strip-shaped touch electrodes comprise a plurality of first strip-shaped touch electrodes that are spaced at a certain distance and arranged parallel to a first direction and a plurality of second strip-shaped touch electrodes that are spaced at a certain distance and arranged parallel to a second direction, wherein the plurality of first strip-shaped touch electrodes and the plurality of second strip-shaped touch electrodes are located in different layers,
wherein the at least one bendable bending region is strip-shaped extending across the first direction or the second direction,
wherein the disconnected strip-shaped touch sub-electrodes from a same touch electrode are connected to a same flexible circuit board to receive a same driving signal, wherein different touch sub-electrode drive signal lines respectively provide the disconnected strip-shaped touch sub-electrodes with a same sensing signal,
wherein the bending region comprises n first-directional bending regions extending along the first direction, at least one of the second strip-shaped touch electrodes are separated into (n+1) disconnected second strip-shaped touch sub-electrodes by the first-directional bending regions, each of the second strip-shaped touch sub-electrodes is driven by a second strip-shaped touch sub-electrode signal line, and n is a positive integer, and
wherein the bending region further comprises m second-directional bending regions extending along the second direction, at least one of the first strip-shaped touch electrodes are separated into (m+1) disconnected first strip-shaped touch sub-electrodes by the second-directional bending regions, each of the first strip-shaped touch sub-electrodes is driven by a first strip-shaped touch sub-electrode signal line, and m is a positive integer.

2. The touch member of claim 1 , wherein each of the first-directional bending regions is located between two adjacent first touch electrodes, and different first-directional bending regions are respectively located between different two adjacent first touch electrodes.

3. The touch member of claim 1 , wherein each of the second-directional bending regions is located between two adjacent second touch electrodes, and different second-directional bending regions are respectively located between different two adjacent second touch electrodes.

4. The touch member of claim 1 , wherein the bending region has a width of 1 μm to 10 μm.

5. A display device, comprising the touch member as defined in claim 1 .

6. The display device of claim 5 , further comprising a flexible circuit board, and different signal lines connected to a same touch electrode are electrically connected by the flexible circuit board.

7. The display device of claim 6 , wherein the flexible circuit board provides a same sensing signal to each of the touch sub-electrodes of the same touch electrode.

8. The display device of claim 1 , wherein the first touch sub-electrode signal lines and the second touch sub-electrode signal lines are substantially parallel with each other at corresponding sections.
