Problems solved by technology

The metal mask includes a display area corresponding to the display area of ​​the subsequently formed display substrate, and a plurality of pixel openings are arranged in the display area, so that the intensity of the display area is lower than that of the surrounding area, so that the intensity of the display area is lower than that of the surrounding area. During the stretching process, the display area of ​​the metal mask is different from other areas in strength, and wrinkles are prone to occur, especially for metal masks with special-shaped display areas, the above problems will be more prominent

Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the content related to the present invention. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart describes various operations (or steps) as sequential processing, many of the operations can be implemented in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The processing may be terminated when its operation is completed, but may also have additional steps not included in the drawings. The processing may co...

Abstract

The invention discloses a metal mask plate and a preparation method thereof. The preparation method of the metal mask plate comprises the steps that a mask plate base material is provided; a first area in the middle portion is thinned at the first side of the mask plate base material, and the first area comprises a non-display area; and multiple pixel holes in at least one display area are formedin the first side. According to the technical scheme provided by the embodiment, the strength difference between the display areas and the periphery area in the formed metal mask plate is reduced, theprobability of generating wrinkles of the metal mask plate in the net standing process is reduced, and the net standing precision of the metal mask plate is improved.

Description

Technical field [0001] The embodiment of the present invention relates to a manufacturing technology of a metal mask, in particular to a metal mask and a preparation method thereof. Background technique [0002] Organic light-emitting display devices have the advantages of self-luminescence, no backlight, flexible display, wide viewing angle, and high color saturation. They are widely used in various electronic devices and are favored by users. [0003] In the preparation process of the organic light-emitting display device, the vapor deposition material is vapor-deposited to the corresponding position of the pixel on the substrate through the mask of the metal mask to form an organic light-emitting functional layer. The metal mask includes a display area corresponding to the display area of ​​the subsequently formed display substrate. A plurality of pixel openings are arranged in the display area, resulting in the intensity of the display area being lower than the intensity of the...
