Abstract

The invention provides a mask plate, an organic display device and a preparation method of the organic display device. The organic display device comprises a substrate and an electrode layer, whereinthe electrode layer is arranged on the substrate and provided with a first electrode area and a second electrode area surrounding the first electrode area, and the thickness of the second electrode area is smaller than the thickness of the first electrode area.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a mask plate, an organic display device and a preparation method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) has become an emerging technology in the display field due to its advantages of high brightness, self-luminescence, fast response and low driving voltage. Its wide-scale commercialization. Inkjet printing has the advantages of high material utilization rate, and is the key technology to solve the cost problem of large-size OLED display. This method uses multiple nozzles to drop functional material ink into the predetermined pixel area, and then obtains the required film by drying. [0003] The thickness and morphology of the organic functional layer are crucial to the light-emitting characteristics of OLEDs. As users have higher and higher requirements for resolution, OLEDs with a top-emitting structure will be limited by the aperture ratio, ...
