Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the invention clearer, the implementation manner of the invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the inventive concept to those skilled in the art, and the invention will only be defined by the appended claims. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. It will be understood that when an element such as a layer, region or substrate is referred to as being "formed on" or "disposed on" another element, it can be directly on the other element or present middle element. In contrast, when an element is referred to as being "directly formed on" or...

Abstract

A method for preparing a patterned organic functional layer provided by the present invention comprises the following steps: sequentially forming an organic functional layer, a first protective layer and a second protective layer on a substrate, and etching away part of the second protective layer Exposing part of the first protective layer; sublimating the exposed second protective layer, thereby exposing the organic functional layer; aligning the substrate with the base material, and then placing the exposed second protective layer in a high temperature environment The organic functional layer is transferred onto the substrate. The method provided by the invention does not need a precise mask plate when preparing the light-emitting layer in the high-resolution OLED device, thereby reducing the production cost and improving the yield.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescent devices, and in particular relates to a preparation method of a patterned organic functional layer and a high-resolution OLED device prepared by the method. Background technique [0002] Organic electroluminescence device OLED generally includes a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer. At present, the light emitting layer of a full-color OLED requires multiple use of a precision mask Fine Metal Mask (FMM) to vapor deposition. [0003] The development of high-resolution organic electroluminescent devices is limited due to the material and manufacturing process of the precision mask FMM itself. During the evaporation process, every time the mask is replaced, it needs to be accurately aligned with the substrate to be evaporated. However, during the alignment, the precision mask FMM often ha...
