Abstract: An optical touch display panel includes a plurality of light-sensing touch units and a position detecting circuit. Each light-sensing touch unit includes a light-sensing component, a storage capacitor, a signal reading component, and a charging component. The light-sensing component senses a light source to generate a sensing signal. The storage capacitor is connected electrically to the light-sensing component for storing the sensing signal. The signal reading component is connected electrically to the storage capacitor for reading a voltage of the storage capacitor to generate a reading signal. The charging signal is connected electrically to the storage capacitor for charging the storage capacitor to reset an electric charge record of the storage capacitor. The position detecting circuit is connected electrically to the light-sensing touch units for detecting a touch point on the optical touch display panel according to a reading signal output by each of the light-sensing touch units.
