Abstract
A touch panel includes a substrate and a first sensor element disposed on the substrate. The first sensor element includes a light-shielding conductive layer, a first transparent conductive layer, a first photosensitive layer, and a first electrode electrically connected to the first photosensitive layer. The light-shielding conductive layer and the first transparent conductive layer are interposed between the first substrate and the first photosensitive layer. A transmittance of the light-shielding conductive layer is smaller than a transmittance of the first transparent conductive layer.
Claims11
A touch panel, comprising:
- a substrate;
- a first sensor element disposed on the substrate and comprising:
- a light-shielding conductive layer;
- a first transparent conductive layer;
- a first photosensitive layer, and the light-shielding conductive layer and the first transparent conductive layer interposed between the substrate and the first photosensitive layer;
- and
- a first electrode electrically connected to the first photosensitive layer,
- wherein a light transmittance of the light-shielding conductive layer is smaller than a light transmittance of the first transparent conductive layer;
- and
- a second sensor element disposed on the substrate and comprising a second photosensitive layer, wherein the second sensor element does not contain a light-shielding conductive layer interposed between the substrate and the second photosensitive layer.
