Abstract: Provided is a mask, which includes: a mask body, including a plurality of grooves, wherein the plurality of grooves are distributed at intervals on a first surface of the mask body, and a hollowed-out structure is provided in the groove; and a mask strip disposed on the mask body, wherein a pattern region of the mask strip is within an orthographic projection of the groove on the first surface.

Abstract: Compounds and methods for inhibiting STAT3.

Abstract: The present disclosure relates to a mask plate, a mask plate structure and a mask plate manufacturing method, belonging to the field of evaporation. The mask plate comprises a mask plate main body and mask strips. The mask plate main body comprises a plurality of grooves, the plurality of grooves are distributed at intervals on a first surface of the mask plate main body, and a hollowed-out structure is arranged in each groove; and the mask strips are located on the mask plate main body, and a pattern region of each mask strip is located in an orthographic projection of the groove on the first surface. During the process of attaching the mask strips to a substrate, the substrate exerts, on the mask strips, a force towards the mask plate main body, so that the middle portion of each mask strip moves towards the groove, and there is no friction force between the middle portion of the mask strip and the substrate.

Abstract: Provided is a mask plate assembly. The mask plate assembly includes: a frame, wherein an opening portion is defined in a center portion of the frame; a shielding strip, wherein the shielding strip is disposed on the opening portion, and two ends of the shielding strip are fixed on the frame; and a mask plate, wherein the mask plate is fixed on the frame, and an evaporation hold and an elongated hole are defined in the mask plate, wherein the evaporation hole is opposite to the opening portion, and the elongated hole is opposite to the shielding strip to shield the elongated hole by the shielding strip.
