Abstract

A portable electronic device with a touch illumination function and a touch illumination method thereof are provided. The portable electronic device with the touch illumination function includes an input module, a touch sensor, and an illumination module. The touch sensor is disposed around the input module, senses a touch motion of the input module, and generates a touch signal according to the touch motion. The illumination module is disposed around the input module, coupled with the touch sensor, and controls the illumination module to generate a light source to illuminate the input module according to the touch signal.

Claims

1. A portable electronic device with a touch illumination function, comprising:

an input module;

a touch sensor disposed around the input module, sensing a touch motion of the input module, and generating a touch signal according to the touch motion; and

an illumination module disposed around the input module and coupled with the touch sensor, wherein the illumination module is controlled to generate a light source to illuminate the input module according to the touch signal.

2. The portable electronic device according to claim 1, wherein the illumination module receives the touch signal and turns on the light source for a predetermined time.

3. The portable electronic device according to claim 1, wherein the illumination module receives the touch signal and turns on the light source, and the illumination module turns off the light source after receiving the touch signal again.

4. The portable electronic device according to claim 1, wherein the input module is chosen from a function key, a keyboard, a slot, and a combination of the above-mentioned.

5. The portable electronic device according to claim 1, wherein the input module has a transparent portion, and the illumination module transmits light via the transparent portion.

6. A touch illumination method, applied to a portable electronic device, wherein the portable electronic device comprises an input module, a touch sensor, and an illumination module, the touch illumination method comprising:

sensing a touch motion of the input module;

generating a touch signal according to the touch motion by the touch sensor; and

generating a light source according to the touch signal by the illumination module.

7. The touch illumination method according to claim 6, further comprising:

turning on the light source for a predetermined time after the illumination module receives the touch signal.

8. The touch illumination method according to claim 6, further comprising:

continuously turning on the light source after the illumination module receives the touch signal; and

turning off the light source after the illumination module receiving the touch signal again.
