Abstract
The present disclosure provides an organic light-emitting diode (OLED) substrate and a method for manufacturing same. The method includes providing a substrate that includes a non-pixel area, a first pixel area, a second pixel area, and a third pixel area; forming a first sacrificial layer in the first pixel area and the second pixel area, forming a third light-emitting material layer on the substrate, and removing the first sacrificial layer, so as to form a third pixel area organic layer; and using the same steps to form a second pixel area organic layer and a first pixel area organic layer.

A method for manufacturing an organic light-emitting diode (OLED) substrate, comprising steps of:
- a step S10 of providing a substrate that includes a pixel area and a non-pixel area, wherein the pixel area includes a first pixel area, a second pixel area, and a third pixel area;
- a step S20 of forming a first sacrificial layer in the first pixel area and the second pixel area, forming a third light-emitting material layer on the substrate, and removing the first sacrificial layer to expose the first pixel area and the second pixel area and to form a third pixel area organic layer;
- a step S30 of forming a second sacrificial layer in the first pixel area and the third pixel area, forming a second light-emitting material layer on the substrate, and removing the second sacrificial layer to expose the first pixel area and the third pixel area and to form a second pixel area organic layer;
- and
- a step S40 of forming a third sacrificial layer in the second pixel area and the third pixel area, forming a first light-emitting material layer on the substrate, and removing the third sacrificial layer to expose the second pixel area and the third pixel area and to form a first pixel area organic layer;
- wherein one of a vacuum evaporation technique, a physical vapor deposition technique, a chemical vapor deposition technique, and a pulsed laser deposition technique is used to form the first light-emitting material layer, the second light-emitting material layer, and the third light-emitting material layer.
