The present disclosure relates to a mask sheet. The mask sheet includes a plurality of mask units. Each mask unit includes an evaporation effective area and a plurality of welding areas that are distributed around the evaporation effective area according to a preset rule. The distribution of the welding areas around the evaporation effective areas of the mask units at the edge of the mask sheet is consistent with the distribution of the welding areas around the evaporation effective areas of the mask units located in the inner region of the mask sheet.

Mask sheet and method for manufacturing the same

The embodiments of the present disclosure propose a device for inspecting a mask plate, a method for inspecting a mask plate, and a corresponding method for controlling light sources. The device includes: an image sensor configured to capture an image of the mask plate; and a plurality of light sources disposed on one side of the mask plate opposite to the image sensor, wherein at least one of the plurality of light sources is configure to emit light when the image sensor is capturing an image of a first region of the mask plate, and the at least one light source comprises light sources within a first range, wherein the first range corresponds to the first region and an orthographic projection of the image sensor on a light source plane falls within the first range. The method for controlling light sources includes: turning on at least one of a plurality of light sources disposed on one side of the mask plate opposite to an image sensor, which corresponds to a first region of the mask plate to be inspected, when the image sensor is moved to a position corresponding to the first region.
