Organic light emitting diode (OLED) illumination panel

Abstract

The invention discloses a more attractive organic light emitting diode (OLED) illumination panel. The structure comprises an anode layer and a cathode layer, wherein both an illumination layer and an auxiliary electrode are positioned between the anode layer and the cathode layer; the anode layer consists of transparent anodes; the cathode layer consists of metal cathodes; the auxiliary electrodeis communicated with the transparent anodes and consists of independent auxiliary electrode monomers; and each auxiliary electrode monomer is communicated with the transparent anodes. The auxiliary electrode monomers have the same shape or different shapes. The auxiliary electrode consists of a plurality of auxiliary electrode monomers; the auxiliary electrode arranged on the transparent anodes is changed into a macroscopic structure; by utilizing the characteristic of opaqueness of the auxiliary electrode, star-speckled patterns are formed, so that the OLED illumination panel becomes more attractive; and the size and the density of the auxiliary electrode are determined according to the potential drops of different parts on the illumination panel, so that the impedance of the anodes can be further reduced and then the brightness uniformity of the panel is improved.

Description

technical field [0001] The invention relates to an OLED lighting panel, which belongs to the technical field of lighting panel manufacturing. Background technique [0002] The existing OLED lighting panel is composed of a transparent anode layer, a luminous layer and a metal cathode layer. The anode layer is composed of a transparent anode, and the cathode layer is composed of a metal cathode. Since the square resistance of the transparent anode is relatively large, about 10Ω / □, The voltage drop is serious. Generally, the farther away from the power supply point of the general OLED surface, the more obvious the voltage drop phenomenon is, resulting in obvious uneven brightness of the lighting panel. In order to improve the unevenness of the brightness of the lighting panel, many schemes have been proposed. Basically, auxiliary electrodes connected to the transparent anode and connected to each other are added on the transparent anode layer. Small, about 1Ω / □, the current vo...
