Abstract
An electronic device includes an infrared distance measurement apparatus and a touch panel. The touch panel covers the infrared distance measurement apparatus. The infrared distance measurement apparatus includes an infrared-light-emitting tube and at least two infrared-light-receiving tubes. The at least two infrared-light-receiving tubes include a far-channel receiving tube and a near-channel receiving tube, and a distance between the far-channel receiving tube and the infrared-light-emitting tube is greater than a distance between the near-channel receiving tube and the infrared-light-emitting tube.
