Abstract

The invention discloses a touch pad which includes: a touch surface layer made by a transparent material; an electrode layer laid under the touch surface layer composed of a first coordinates array pre-set by a transparent electrode; a lighting element layer set under the electrode layer composed of lighting element that can control lighting point array; a control device that is electric coupled with the electrode layer and the lighting element layer. The invention also discloses a notebook computer and a method for controlling light effect on the touch pad. The touch pad can provide lighting feedback corresponding to a user's touch position for the user in time according with the user's touch.

Description

technical field [0001] The invention relates to information feedback technology of electronic equipment, in particular to a touch panel, a notebook computer and a method for controlling light effects on the touch panel. Background technique [0002] Currently, on most notebook computers, a touch pad is used as a component for selecting functions such as "cursor navigation" and "selection" and "confirmation". The touch panel usually adopts the principle of capacitive sensing, and some electrodes are designed and manufactured on the upper surface of the PCB board, and a layer of plastic plate is covered on the electrode surface. When a person's finger slides on the plastic board, the capacitance value on the electrode will change, so that the coordinate value of the finger on the PCB board and the change of the coordinate value can be detected, and the coordinate value is corresponding to the display. Functions such as "cursor navigation" can be realized. [0003] For a long...
