Abstract
A sensing unit measuring a bending degree of a flexible substrate includes: a first line formed on the flexible substrate; a second line adjacent to the first line; and a first controller applying a first sensing signal to the first line and measuring a change of crosstalk generated in the second line by the first sensing signal according to bending of the flexible substrate.
Claims3
A display device comprising:
- a flexible substrate;
- a first line positioned on the flexible substrate and connected to a pixel for displaying an image;
- a second line adjacent to the first line;
- a first pixel driver for applying a first sensing signal to the first line and measuring a change of a crosstalk generated in the second line by the first sensing signal according to a bending of the flexible substrate;
- a third line positioned on the flexible substrate, extending in a second direction crossing a first direction, and connected to the pixel;
- a fourth line adjacent to the third line and extending in the second direction;
- and
- a second pixel driver for applying a second sensing signal to the third line and measuring the crosstalk generated in the fourth line by the second sensing signal,
- wherein the first line and the second line extend in the first direction on the flexible substrate.
