摘要:
A lighting touchpad is provided, which includes a substrate module, a plurality of sensing electrodes, a plurality of driving electrodes, a plurality of light emitting diode (LED) chips mounted on the substrate module, and a controller. The driving electrodes and the sensing electrodes are formed on the substrate module. The driving electrodes define a distribution space that extends along a normal direction of the substrate module. The LED dies are arranged in the distribution space. The controller is electrically coupled to the sensing electrodes, the driving electrodes, and the LED dies through the substrate module. When a coupling capacity is generated between a conductor and at least one of the sensing electrodes, the controller is configured to drive at least one of the LED dies adjacent to the at least one of the sensing electrodes to emit light.
