Abstract
An OLED plate comprises: a substrate; a plurality of OLED devices, disposed on one side of the substrate and located in the display area; and an auxiliary cathode, disposed on the one side of the substrate and at least located in the peripheral area. Each of the OLED devices includes a reflective anode, an organic material functional layer and a transparent cathode disposed in a direction distal from the substrate in sequence. A portion of the auxiliary cathode located in the peripheral area is electrically connected to transparent cathodes of the plurality of OLED devices, and resistivity of the auxiliary cathode is less than resistivity of a transparent cathode of the plurality of OLED devices.
