1. A touch panel comprising:
- a substrate; and
a plurality of optical devices arranged on a flange of the substrate,wherein the optical devices comprise a plurality of light emitting devices for emitting light and a plurality of light receiving devices for receiving the light emitted by the plurality of light emitting devices,wherein the substrate comprises a first side, a second side opposite to the first side, a third side adjacent to the first and second sides, and a fourth side opposite to the third side and adjacent to the first and second sides,wherein the plurality of light emitting devices are arranged on a flange of each of the first, second, third and fourth sides of the substrate,wherein the plurality of light receiving devices are arranged on the flange of each of the first, second, third and fourth sides of the substrate,wherein a first gap between a first light emitting element and a first light receiving element is smaller than a second gap between the first light receiving element and a second light receiving element,wherein the first light emitting element, the first light receiving element and the second light receiving element are serially disposed in at least one of the first side, the second side, the third side or the fourth side,wherein a gap between adjacent two of light receiving elements are uniform in size in at least one of the first side, the second side, the third side or the fourth side, andwherein the plurality of light receiving elements are disposed between adjacent two of light emitting elements.
