DISPLAY, TOUCH PANEL AND ELECTRONIC DEVICE
First Claim
1. A display comprising:
- a plurality of display elements performing display based on picture signals supplied to a plurality of picture signal lines, respectively;
a plurality of sensor elements outputting touch signals indicating detection of an external proximity object to a plurality of sensor signal lines, respectively;
a detection section detecting each of the touch signals;
a transfer output section transferring and outputting a detection result of the detection section to outside; and
a control section controlling operations of the detection section and the transfer output section, allowing the transfer output section to operate in a case where the touch signal is detected in the detection section, and suspending an operation of the transfer output section in a case where the touch signal is not detected.

Abstract
A display with a touch panel allowed to achieve high response performance while reducing power consumption is obtained. The display includes a plurality of display elements performing display based on picture signals supplied to a plurality of picture signal lines, respectively, a plurality of sensor elements outputting touch signals indicating detection of an external proximity object to a plurality of sensor signal lines (SGL), respectively, a detection section (a comparator 331) detecting each of the touch signals, a transfer output section (a D-type flip-flop 332 and an output buffer circuit 36) transferring and outputting a detection result of the detection section to outside, and a control section (a transistor switch SCW, a transfer clock control circuit 37 and a timing generator 35) controlling operations of the detection section and the transfer output section, allowing the transfer output section to operate in a case where the touch signal is detected in the detection section, and suspending an operation of the transfer output section in a case where the touch signal is not detected.
