Abstract
The Present Disclosure provides a touch panel, which consists of a main panel and a light-emitting touch module mounted under the main panel. The light-emitting touch module consists of a first circuit board provided with a plethora of touch sensors and light-emitting devices under the main panel. These touch sensors are used to induce the approaching signals of the operator, and transmit the induction signals to a touch control circuit for controlling the light-emitting status of the corresponding light-emitting device. The light-emitting touch module also consists of a second circuit board, electrically connected with the first circuit board. The touch control circuit is provided on the second circuit board, spatially separated from the first circuit board by a certain distance, so that the electromagnetic interferences of the touch control circuit on the touch sensors may be reduced.
