TOUCH PANEL
First Claim
1. A touch panel comprising:
- a first pixel including a first photosensor portion detecting light with a first color;
a second pixel including a second photosensor portion detecting light with a second color;
a first A/D converter performing A/D conversion on an output signal of the first photosensor portion; and
a second A/D converter performing A/D conversion on an output signal of the second photosensor portion,wherein voltage resolution of the first A/D converter and voltage resolution of the second A/D converter are different.

Abstract
An embodiment of the present invention provides a touch panel that enable data sensing with multi-gray scale and an electronic device. At least a first pixel including a first photosensor portion detecting light with a first color, a second pixel including a second photosensor portion detecting light with a second color, a first A/D converter performing A/D conversion on an output signal of the first photosensor portion, and a second A/D converter performing A/D conversion on an output signal of the second photosensor portion are included. The voltage resolution of the first A/D converter and the voltage resolution of the second A/D converter are different.
