Patent ID: 8860687

Claim:
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 plurality of detection sections, each detecting a touch signal from the corresponding sensor signal line; 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 any of the detection sections, and suspending an operation of the transfer output section in a case where the touch signal is not detected, wherein the transfer output section includes a shift register having a plurality of flip-flops each holding and outputting an output value of the corresponding detection section, the shift register performing a parallel-serial conversion of the detection result by using the flip-flops, and the control section includes a plurality of switches, each of which independently connects an enabling voltage to a transfer clock control circuit for allowing the shift-register to perform the parallel-serial conversion, depending upon the output value output from the corresponding flip-flop for each of the switches.
