Abstract

An optical touch display panel includes a plurality of resetting signal lines, a plurality of scanning signal lines, and a plurality of optical sensing touch units. Each optical sensing touch unit includes an optical sensing element and a storage capacitor. The optical sensing elements in a first direction are connected electrically to different scanning signal lines, and are configured to respectively receive a control signal. The optical sensing elements in a second direction includes a plurality of groups, and the optical sensing elements of each group are connected electrically to different resetting signal lines, so that each group receives a reset signal. Each optical sensing element outputs a charging signal corresponding to the reset signal to the storage capacitor according to the control signal, so as to reset a voltage of the storage capacitor.
