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.
