Abstract

The embodiment of the invention provides a mask, a manufacturing method of the mask and a mask assembly, and relates to the field of masks. The problem that welding failures are caused by the fact that laser energy is difficult to control during welding can be solved; the mask includes a mask pattern region and a non-mask pattern region around the mask pattern region; the mask pattern region includes at least one effective mask region; the effective mask region includes a plurality of evaporation holes and shielding strips located between the evaporation holes; the mask is provided with a soldering region in the non-masking pattern region; and at least the thickness of the soldering region of the non-masking pattern region of the mask is larger than the thickness of the shielding strips inthe effective mask region of the mask.

Description

Technical field [0001] The invention relates to the field of mask plates, in particular to a mask plate, a manufacturing method thereof, and a mask plate assembly. Background technique [0002] In the manufacturing process of electronic products, masks are often used to form various patterned film layers; for example, for the evaporation of organic light emitting layers in organic light emitting diode (Organic Light Emitting Diode, OLED) display devices. [0003] When using a mask to form a patterned film, it is often necessary to spread the mask and weld it on the frame; however, due to the small thickness of the mask body, it is difficult to control the laser energy when using laser welding. If the energy of the laser is too large, it is easy to cause weld penetration, and if the energy of the laser is too small, it is easy to cause a virtual welding phenomenon. Summary of the invention [0004] The embodiment of the present invention provides a mask, a manufacturing method there...
