Problems solved by technology

[0004] In related technologies, during the stretching process, when the two ends of the support bar are subjected to tension, they will deviate in the non-stretching direction, resulting in poor shielding effect, which in turn leads to poor display of the screen formed after evaporation

Abstract

The invention relates to a support bar and a mask plate. The support bar is provided with a support area and a clamping area, and comprises a body, a special-shaped part and a clamping part, wherein the body is arranged in the support area; the special-shaped part is arranged in the support area, and is positioned on at least one side of the body in a first direction; the clamping part is arrangedin the clamping area, and is positioned at the two ends of the body along a second direction; the body is provided with a first central axis parallel to the second direction; the clamping part is provided with a second central axis parallel to the second direction; the support area is provided with a first centroid main axis parallel to the second direction; in the first direction, the second central axis is positioned on the side, pointing to the first centroid main axis, of the first central axis; and the first direction and the second direction are perpendicular to each other, and are on aplane on which the body is positioned. The distance between an action line of axial force and the first centroid main axis is reduced, so that the distance between the action line of the axial forceand a second centroid main axis of the whole support bar is reduced, the eccentric distance is reduced, and the bending moment is reduced correspondingly, so that the offset of the support bar in thenon-stretching direction is reduced.

Description

technical field [0001] The invention relates to the field of vapor deposition technology, in particular to a support bar and a mask plate. Background technique [0002] With the advancement of science and technology and the continuous development of the information age, people's requirements for various performances of displays are gradually increasing. Among them, organic light-emitting diodes (OLEDs) have gradually replaced liquid crystal displays due to their low driving voltage, active light emission, wide viewing angle, high efficiency, fast response speed, and easy realization of full-color large-area wall-mounted displays and flexible displays. [0003] In OLED manufacturing technology, the mask plate becomes a crucial part in the evaporation process because it can effectively control the position of the organic material deposited on the substrate. The mask plate generally includes a frame, a support bar and a mask bar. The support bar is fixed on the frame to suppor...
