Abstract
A mask, a manufacturing method therefor, and a manufacturing method for a display substrate are provided. The mask includes: a first clamping region and a second clamping region, which are opposite to each other in a first direction, and at least one mesh region between the first clamping region and the second clamping region, the mesh region is in a first shape, in a case where the mask is stretched in the first direction, the mesh region is in a target shape, the target shape is different from the first shape, and the target shape includes a polygon shape, a circle shape, or an ellipse shape.
Claims14
A manufacturing method for a mask, comprising:
- providing a test mask, wherein the test mask comprises a first clamping region and a second clamping region, which are opposite to each other in a first direction, and further comprises at least one mesh region between the first clamping region and the second clamping region, the at least one mesh region is in a target shape,
- acquiring deformation state information of the mesh region in a case where the test mask is stretched along the first direction,
- acquiring reverse compensation information for the mesh region according to the deformation state information, and obtaining target initial state information of the mesh region based on the reverse compensation information, and
- manufacturing a mask according to the target initial state information, and the at least one mesh region of the mask manufactured being in a first shape.
