The above-mentioned creative objects and advantages of the present invention are not difficult to understand from the detailed description of the selected embodiments and the accompanying drawings.

Referring to FIG. 1 to FIG. 4 , the first embodiment of the present invention relates to a light-emitting device for a touch panel, comprising: an electronic device 10 , a touch panel 20 , and a plurality of light sources 30 .

The electronic device 10 is a notebook computer, and the embodiment is described by a notebook computer.

The electronic device 10 includes a housing 11 , wherein the housing 11 has an opening 12 , and the touch panel 20 is disposed in the opening 12 .

The touch panel 20 is composed of a light guide plate (LGP) 21 and a circuit board 22, and has a touch area 201. The touch panel 20 senses the touch area 201. A contact is generated to generate an inductive signal, and when a finger touches a fixed position of the touch operation area, a signal of a capacitance sensing potential change is generated. The circuit board 22 has a sensing portion (not shown) in which a plurality of XY-axis matrix arrays are arranged, and the plurality of XY-axis sensing portions correspond to the position of the touch region 201 on the top surface of the touch panel 20, and can When the finger touches the fixed position of the touch area 201, a signal of a capacitance sensing potential change is generated. In addition, the light guiding film 21 belongs to a transparent silicone light guiding material, and has a uniform light guiding function, and the light guiding film 21 can be a thin plate with color, and can be replaced at any time according to the needs of the user, so that The electronic device 10 has a variety of appearances.
