Abstract
An organic light-emitting diode display panel and a display device are provided in the present disclosure. The organic light-emitting diode display panel includes a general display region and a light-transmitting display region, wherein the light-transmitting display region corresponds to an under-screen camera placement region; the organic light-emitting diode display panel further includes an array unit and a light-emitting unit disposed on an upper side of the array unit, and the light-emitting unit includes a cathode layer disposed on a surface of the array unit. The cathode layer includes a second cathode portion corresponding to the light-transmitting display region, and a first cathode portion corresponding to the general display region, and the second cathode portion and the first cathode portion are disconnected from each other to connect different voltages respectively.
