Abstract: Each of frame display periods is for performing a display operation based on image information on one frame and each of detection surface touch detection periods is from when touch detection is started to when the detection is completed on the entire detection surface. At least one frame display period of the frame display periods and at least one detection surface touch detection period of the detection surface touch detection periods are started based on a display synchronization signal. The display operation and the touch detection operation are performed in a time-division manner in the one frame display period. The length of the one detection surface touch detection period is longer than the one length of the frame display period.

Abstract: A sensor module comprises a non-contact sensor array having a plurality of sensors, a control unit configured to receive a detection signal output from the non-contact sensor array and to generate coordinate information based on the detection signal, a drive unit configured to receive the coordinate information from the control unit and to output a drive signal based on the coordinate information, and a light shielding panel overlapping the non-contact sensor array, the light shielding panel configured to be driven based on the drive signal, wherein the light shielding panel is switchable between blocking and transmitting light traveling in a direction parallel to a main surface of the non-contact sensor array.
