Abstract: 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. A direction along which the clamping portion extends from the substrate to a direction away from the substrate is a first direction, a direction perpendicular to the first direction is a second direction.

Abstract: The present disclosure provides a mask and a manufacturing method thereof, an evaporation method and a display screen, to achieve normal display of an area around such components as an earpiece, a front camera, and sensors on the front of a display screen, and increase the screen-to-body ratio. The mask comprises a substrate provided with at least one opening, an orthographic projection of the opening on a display plane of a display screen to be fabricated coinciding with a display area of the display screen to be fabricated; a shielding part arranged inside the opening, an orthographic projection of the shielding part on the display plane coinciding with an orthographic projection of a component to be shielded in the display screen to be fabricated on the display plane; and a connecting part located between the shielding part and a side wall of the opening.
