Abstract:
1. A touch panel comprising: a first substrate; a pixel comprising a photosensor portion and a MEMS portion, over the first substrate; a second substrate over the pixel; and a processing circuit, wherein the photosensor portion comprises a photodiode, wherein the MEMS portion comprises a MEMS element, wherein a spacer is provided in contact with the MEMS element and between the MEMS element and the second substrate, wherein the photosensor portion is configured to detect light from an object contacting with a surface of one of the first substrate and the second substrate, wherein the processing circuit is configured to detect a position and an area of a region where the object is contacting a surface of the one of the second substrate, and wherein the MEMS portion generates a force, corresponding to the position and the area of the region where the object is contacting the surface of the second region, in a direction perpendicular to the first substrate and the second substrate in response to a signal supplied from the processing circuit.
