A mask includes a mask frame including a first opening part; a first mask disposed on the mask frame and including a second opening part overlapping the first opening part in a plan view; a second mask including a mesh part having a mesh shape overlapping the second opening part in a plan view and disposed on the first mask; and a fixing part disposed on the second mask and extending along an edge of the second mask to surround the mesh part.

A mask includes a protruding portion provided with a deposition hole formed therethrough and including an upper surface, a lower surface facing the upper surface, and a side surface disposed between the upper surface and the lower surface and inclined at an angle with respect to the lower surface, a peripheral portion including a first surface extending from the upper surface, a second surface facing the first surface and having a step difference with respect to the lower surface of the protruding portion, and a coating layer disposed on the protruding portion. The protruding portion includes at least one of a protrusion protruded from the side surface of the protruding portion and a groove formed by removing at least a portion of the protruding portion from the side surface of the protruding portion, and the coating layer covers at least one of the protrusion and the groove.

A full-color silicon-based organic light-emitting diode structure includes a metal anode layer, an organic functional layer, a metal cathode layer, an encapsulation layer, and a color filter layer. The organic functional layer includes a light-emitting layer configured to emit white light. The light-emitting layer includes a red light-emitting unit, a blue light-emitting unit, a green light-emitting unit, and a light-emitting common transport layer. The red light-emitting unit and the blue light-emitting unit are vapor-deposited on the same fine metal mask, and other structural film layers are vapor-deposited on a common metal mask. The present disclosure overcomes problems that red, green, and blue spectra cannot appear at the same time due to different lengths of red, green, and blue resonant cavities, the color gamut of the product is low due to large intensity differences, and the product life is affected due to large light loss caused by the color filter.

A deposition mask set includes a first mask, a second mask, and a third mask. Each of the first mask, second, and third masks includes a first edge substantially parallel to a first direction, a second edge substantially parallel to a second direction, and a plurality of first openings. Each of the openings includes a first opening side that is substantially parallel to a third direction and a second opening side that is substantially parallel to a fourth direction, and each of the openings corresponds to one of a first, second, or third color area at one of pixel areas. The third and fourth directions are not parallel to the first and second directions, and the first, second, and third color areas are adjacent to each other in the third direction.

The present disclosure provides a display panel and a mask. The display panel does not dispose a common electrode layer in a transparent area and an aisle area, and by this way, after the transparent area of the display panel is cut to form a through-hole, the common electrode layer can still be protected by other film layers and not be directly exposed to air, thereby preventing intrusion of water and oxygen.

A mask assembly includes a frame including long side portions extending in a first direction and spaced apart from each other in a second direction intersecting the first direction, and short side portions connected to the long side portions, the frame defining a frame opening, a first stick extending in the second direction and connected to the frame, a first mask sheet defining first deposition openings and connected to the first stick and the frame, at least part of the first deposition openings arranged in the first direction and overlapping the frame opening in a plan view, and a second mask sheet defining second deposition openings and connected to the first stick and the frame, at least part of the second mask sheet arranged in the first direction and overlapping the frame opening in a plan view.

Provided are a deposition mask, a method of manufacturing a display device using the deposition mask, and a display device. The deposition mask includes a main frame defining a first opening; ribs extending away from a side of the main frame, the ribs being apart from each other and defining second openings; and bridges connecting the ribs to one another across the second openings, wherein the bridges and the ribs form the same top surface, and a thickness of each of the bridges is less than a thickness of each of the ribs.

A mask, a manufacturing method thereof, a fine metal mask, a mask device and a use method thereof are provided. The mask includes at least one opening region and a shielding part surrounding and defining the at least one opening region. The shielding part includes a main part and at least one protrusion, in each opening region, the protrusion is protruded towards the opening region on a side of the main part facing the opening region; the main part includes an edge disposed on a side of the protrusion opposite to the opening region and with an extension direction being a same with an extension direction of the protrusion, the protrusion and a portion of the main part disposed between the edge and the protrusion includes a thinning portion with a thickness being less than a thickness of other portions of the shielding part.

A mask device, a mask plate and frame are provided. The mask device includes a frame and a first mask plate. The frame includes an inner edge, an outer edge, and a plurality of mounting grooves. A first mask plate includes a substrate, at least one first mask opening on the substrate, and a plurality of clamping portions protruding and extending outward from at least part of a periphery of the substrate. The plurality of clamping portions are mounted in the plurality of mounting grooves, respectively, so that the substrate is mounted on the inner edge of the frame.
