Abstract
A method for controlling stretching of a mask includes: obtaining actual position information of at least one opening of the mask; determining an actual offset of each opening according to actual position information of the opening and preset position information of a light-emitting region of a sub-pixel corresponding to the opening; determining whether the actual offset of the opening is less than or equal to a theoretical maximum offset of the opening; and in response to determining that the actual offset of the opening is less than or equal to the theoretical maximum offset of the opening, generating a first end command for ending a process of stretching the mask.
