TOUCH SENSING ERROR COMPENSATION
First Claim
1. A touch screen comprising:
- a drive region that is driven by a drive signal;
a sense region that outputs a sense signal that includes information of a first amount of touch on or near the touch screen and information of a first amount of error, wherein the first amount of touch is based on the drive signal;
a compensation sensor that outputs a compensation signal that includes information of a second amount of error; and
an error compensator that compensates for the first amount of error in the sense signal based on the second amount of error.

Abstract
Error compensation of a touch sensing signal is provided. A touch screen can include a drive region that can be driven by a drive signal, and a sense region that can output a sense signal that includes information of a first amount of touch on or near the touch screen and information of a first amount of error. The first amount of touch can be based on the drive signal. The touch screen can include a compensation sensor that can output a compensation signal that includes information of a second amount of error, and an error compensator that can compensate for the first amount of error in the sense signal based on the second amount of error.
