Claim Text:
1. An optical touch module, comprising: a glass panel comprising a front surface and a rear surface opposite to the front surface, the glass panel being divided into a sensing zone and a peripheral zone surrounding the sensing zone; a first strip-shaped carrier disposed on the front surface of the glass panel and arranged within the peripheral zone, the first strip-shaped carrier comprising a first surface and a second surface opposite to the first surface; a first light reflecting strip disposed on the first surface of the first strip-shaped carrier; a second strip-shaped carrier disposed on the front surface of the glass panel and arranged within the peripheral zone, the second strip-shaped carrier comprising a third surface and a fourth surface opposite to the third surface; a second light reflecting strip disposed on the third surface of the second strip-shaped carrier, wherein a first thickness defined between the first surface and the second surface is smaller than a second thickness defined between the third surface and the fourth surface; a control board unit disposed on the rear surface of the glass panel and located completely within the peripheral zone; and a plurality of optical sensing sets disposed at intervals within the peripheral zone of the glass panel, each of the optical sensing sets comprising: wherein the signal transferring portions of the optical sensing sets are electrically connected to the control board unit in serial, and the optical sensing sets and the control board unit jointly form a single-row serial connection structure, and the signal transferring portion of one optical sensing set of the optical sensing sets transfers a signal, based upon the optical signal received by the optical sensing unit of the one optical sensing set, via another of the signal transferring portions to the control board unit.
