Abstract

The invention relates to the technical field of display, in particular to a manufacturing method of a mask plate and the mask plate. The manufacturing method of the mask plate comprises the steps as follows: a mask having multiple pixel openings is obtained, the pixel openings are arranged into at least one rectangular pattern area, and each rectangular pattern area comprises a first area corresponding to a display area of a display panel and a second area except the first area; the mask and a mask frame are aligned, and the mask is fixed on the mask frame; the pixel openings in each second area are blocked, and the mask plate is formed. According to the technical scheme, the condition that wrinkles are produced easily during stretching of the mask can be relieved, so that the problems ofpoor color mixing of the display panel and reduction of the product yield can be solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for manufacturing a mask and the mask. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) usually adopts evaporation technology to prepare the organic light-emitting layer. In the manufacturing process of the display panel, the evaporation material is deposited on the substrate above the evaporation source by high-temperature evaporation. In order to evaporate the evaporation material to a specific position according to the design, a high-precision metal mask is required under the substrate. There are multiple pixel openings on the mask plate and the mask plate (that is, a high-precision metal mask plate), and the evaporation material is deposited on the TFT (Thin Film Transistor, thin film transistor) substrate through each pixel opening to form a display panel An organic light-emitting layer, the organ...
