Abstract
An organic light-emitting diode (OLED) display panel is provided. The OLED display panel includes a light-emitting layer having a first region and a second region; a common electrode layer including a first electrode and a plurality of multiplexed electrodes insulated from one another, wherein the first electrode is opposite to the first region and each multiplexed electrode is opposite to the second region; and a multiplexed functional line, wherein the multiplexed functional line is electrically connected to one of the plurality of multiplexed electrodes, to detect a capacitance change caused by the one of the plurality of multiplexed electrodes and a finger, and thereby generate a fingerprint signal. An increased screen ratio effect is provided.
