Abstract

The invention provides a surface modification mask plate, a manufacturing method thereof and a manufacturing method of an electroluminescence device. The surface modification mask plate has multiple hollow parts and a modified surface; the modified surface includes a first modified surface and a second modified surface; the first modified surface surrounds the hollow parts; the modified surface besides of the first modified surface is the second modified surface; and the first modified surface and the second modified surface are respectively a hydrophilic surface and a hydrophobic surface. When the surface modification mask plate is used for preparing the electroluminescence device, hydrophilic or hydrophobic ink cannot be stained on the surface modification mask plate, so that the mask plate is used for improving the material guidance performance, a spraying process in a solution method can be used for manufacturing pixels, ink jet printing equipment with lower precision can be used for manufacturing the pixels, and finally, the cost needed by precise ink jet printing equipment is reduced.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a surface-modified mask, a manufacturing method thereof, and a manufacturing method of an electroluminescent device. Background technique [0002] With the continuous development of science and technology, people's requirements for display quality continue to increase. OLED (Organic Light Emitting Diode) and QLED (Quantum Dot Light Emitting Diode) are considered to be the most representative display technologies in the future. OLED usually adopts evaporation method to prepare the above-mentioned electroluminescent device, that is, cover the mask plate above the substrate and perform multiple vacuum thermal evaporation to prepare RGB pixels. For example, when evaporating R pixels, the positions corresponding to GB pixels The template is covered so that it is not evaporated. In the above method, the utilization rate of the material is low, resulting in extremely high cost. Based o...
