Abstract

The invention provides an OLED backboard and manufacturing method thereof, and a display device. The OLED backboard includes a substrate and a plurality of organic light-emitting diodes formed on the substrate, each organic light-emitting diode includes a bottom electrode, a top electrode, and organic luminescent materials between the bottom electrode and the top electrode, the thickness of the bottom electrode at the first edge area of the corresponding organic light-emitting diode is greater than that of the central area of the organic light-emitting diode, so that the conductive capability of the first edge area of the bottom electrode is enhanced, and the brightness of the organic luminescent materials at the first edge area is improved, the brightness of the organic light-emitting diodes at the first edge area and the central area is uniform, the OLED color mixing can be prevented, and the display quality of the OLED display device at a large visual angle can be effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED backplane, a manufacturing method thereof, and a display device. Background technique [0002] An organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device is a device that utilizes a reversible discoloration phenomenon generated by an organic semiconductor material driven by an electric current to realize graphic display. OLED display devices are ultra-light, ultra-thin, high brightness, large viewing angle, low voltage, low power consumption, fast response, high definition, shock resistance, bendable, low cost, simple process, less raw materials, high luminous efficiency and temperature Wide range and other advantages, is considered to be the most promising new generation of display technology. [0003] The basic structure of an OLED includes: an anode layer, a cathode layer, and an organic light-emitting layer sandwiched between the anode layer...
