Abstract: Disclosed are a mask and a manufacturing method for the mask, aiming to solve the problem in the prior art of the easy occurrence of color mixing due to the inaccurate position of evaporation when a pattern of a light-emitting substrate is formed by means of a mask. The mask for covering a mother board, which is formed by a multi-division exposure procedure and thus has a substrate invalid region that cannot be exposed due to the multi-division exposure procedure, comprises: a metal frame; a support mask located on one side of the metal frame; at least one fine metal mask strip, which is located on the side of the support mask that faces away from the metal frame, and is provided with multiple openings for the evaporation of a light-emitting film for sub-pixels in the mother board; and a support plate located between the metal frame and the fine metal mask for covering the substrate invalid region, with the thickness of the support plate being greater than that of the support mask.

Abstract: A mask plate and a method for manufacturing the same are provided. The mask plate comprises a first sub-mask plate and a second sub-mask plate stacked with each other, the first sub-mask plate is provided with at least one first opening therein, a size and a shape of the first opening correspond to those of a target display panel; the second sub-mask plate is provided with a second opening region, which covers at least one of the at least one first opening and includes a plurality of second openings. Since it is only required to ensure that the sizes and shapes of the first openings are the same as those of the target display panels respectively, and it is unnecessary to further manufacture openings for forming pixel patterns, comparing with the existing mask plate, the manufacturing process of the present disclosure is more simple and the manufacturing cost is lower.

Abstract: A metal mask plate and a fabrication method thereof. The metal mask plate has a first main surface and a second main surface opposite to each other, the metal mask plate includes: a plurality of panel-defining regions spaced apart; and a main frame portion. In each of the panel-defining regions, a plurality of via holes configured for defining a pixel structure are arranged in a matrix, and each of the via holes communicates the first main surface and the second main surface of the metal mask plate, side walls of every two adjacent via holes are directly connected with each other on the second main surface of the metal mask plate so that the metal mask plate between the two adjacent via holes (101) in the panel-defining region has a thickness D1. The main frame portion of the metal mask plate has a second thickness D2, and the first thickness D1 and the second thickness D2 satisfy |D1−D2|/D1≤20%. Thus, a wrinkle and deformation caused by the difference of the thicknesses during unfolding can be effectively avoid, so as to further effectively improve quality of the OLED display product fabricated by adopting the fine metal mask plate.
