摘要： An optical touch module and an optical touch display panel are provided. The optical touch module includes a first photo sensor, a second photo sensor, and a signal processing unit. The first photo sensor is disposed in one of the plurality of pixels of a pixel array. A first terminal and a control terminal of the first photo sensor are coupled to a first scan line. The second photo sensor has a first terminal coupled to a second terminal of the first photo sensor and outputting a sensing voltage, a control terminal coupled to the first terminal of the second photo sensor, and a second terminal receiving a first voltage. The signal processing unit is coupled to the first terminal of the second photo sensor, so as to convert the sensing voltage to a touch signal.
