Abstract
According to embodiments of the present disclosure, a display device includes a first serial clock signal transmitted from a touch controller to a first read-out integrated circuit, the first serial clock signal having a signal level change at a first time point, and a second serial clock signal transmitted from the touch controller to a second read-out integrated circuit, the second serial clock signal having a signal level change at a second time point different from the first time point. Accordingly, touch signals can be transmitted stably.
Claims20
A display device, comprising:
- a display panel on which a plurality of sub-pixels and a plurality of touch electrodes are disposed;
- a first read-out integrated circuit electrically connected to a first touch electrode;
- a second read-out integrated circuit electrically connected to a second touch electrode;
- a touch controller electrically connected to the first read-out integrated circuit and the second read-out integrated circuit and receiving touch sensing data from the first read-out integrated circuit and the second read-out integrated circuit;
- a first serial clock signal transmitted from the touch controller to the first read-out integrated circuit and having a signal level change at a first time point;
- and
- a second serial clock signal transmitted from the touch controller to the second read-out integrated circuit and having a signal level change at a second time point different from the first time point.
