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.

A sensor module comprising:
- 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.
A touch panel comprising:
- a first sensor module, the first sensor module including 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 configured to be driven based on the drive signal;
- and
- a second sensor module arranged adjacent to the first sensor module, the second sensor module including a substrate, a light emitting unit arranged on the substrate, and a light receiving unit arranged on the substrate and facing the light emitting unit,
- wherein the light shielding panel of the first sensor module is arranged between the light emitting unit and the light receiving unit of the second sensor module.
A touch panel comprising:
- a first sensor module, the first sensor module including a non-contact sensor array having a plurality of sensors, and a first light shielding panel overlapping the non-contact sensor array and switchable between blocking and transmitting a first light traveling in a direction parallel to a main surface of the non-contact sensor array;
- and
- a second sensor module arranged adjacent to the first sensor module, the second sensor module including a substrate, a first light emitting unit arranged on the substrate, and a first light receiving unit arranged on the substrate and facing the first light emitting unit,
- wherein the first light shielding panel is arranged between the first light emitting unit and the first light receiving unit of the second sensor module.
