Abstract

The invention provides an organic electroluminescent display and a manufacture method thereof. The manufacture method comprises the steps of: obtaining a first electrode pattern on a display zone wiring area of a substrate and a peripheral wiring area by using a photoetching technology; sequentially manufacturing an insulating layer and a cathode insulating post, and covering the display zone wiring area and the peripheral wiring area which do not contain the first electrode pattern; evaporating an organic functional material on the display zone wiring area of the substrate where the cathode insulating post is manufactured layer by layer; evaporating a cathode metal on the peripheral wiring area and the display zone wiring area of the substrate where the organic functional material is evaporated; and adhering a rear cover on the substrate where the cathode metal is evaporated by using an encapsulating adhesive. In the embodiment of the invention, the cathode metal is also evaporated on the peripheral wiring area, so that the resistance of peripheral wiring is lowered, and then the voltage of the peripheral wiring is lowered, the power consumption is reduced, and the luminance of the organic electroluminescent display is enhanced.

Description

technical field [0001] The invention relates to the technical field of display manufacturing technology, and more specifically relates to a method for manufacturing an organic electroluminescent display and an organic electroluminescent display. Background technique [0002] Organic electroluminescence display (OLED) is a new type of flat panel display, which has been widely used due to its advantages of active light emission, high contrast, fast response, thin and light. Its basic structure includes an anode, a cathode, and an organic functional layer inserted between the anode and the cathode, including a charge injection layer, a charge transport layer, and a light emitting layer. When an organic electroluminescent display is in operation, the display can emit light by applying an appropriate voltage between the electrodes. [0003] The anode material of OLED generally adopts transparent conductive film indium tin oxide ITO, and the cathode generally adopts metal with lo...
