Abstract
The Present Disclosure provides a touch panel, comprising a main panel and a light-emitting touch module disposed underneath. The main panel is provided with a plurality of display patterns thereon. A light-emitting touch module includes a first circuit board provided with a plurality of touch sensors, a plurality of light-emitting devices and a plurality of light guiding parts attached to the side edges of the light-emitting devices so as to evenly project the light emitted from the light-emitting devices upward to the display patterns. The light-emitting touch module further comprises a light reflecting part disposed underneath the light guiding parts capable of reflecting the light emitted from the bottom surface of the light guiding parts back to the light guiding parts, which is further projected upward from the display patterns so as to improve the brightness of the patterns.
