New description: [New technical field] This creation is related to a metal mask, especially a supporting metal mask that prevents sagging deformation. [Prior Art] A conventional metal mask includes a metal frame and at least one metal thin plate. The periphery of the metal thin plate is attached to the metal frame and has a plurality of meshes. However, such a metal masked metal sheet is liable to cause sagging deformation of a portion where the center lacks support due to its own weight. Taiwan Patent No. 201122122 discloses a metal mask comprising a metal frame, a supporting structure connected to the metal frame, and a metal thin plate, the metal thin plate is attached to the metal frame, and the supporting structure comprises a plurality of Supporting rods, the top surfaces of the supporting rods are completely in contact with the bottom surface of the metal sheet, thereby avoiding the sagging deformation of the metal sheet. A similar supporting structure is disclosed in Taiwan Patent No. 201132771, 201111525 and 201030170. ' There is a mention. _ A support structure such as the above-described conventional metal mask supports the thin metal plate with a straight elongated structure. [New content] The main purpose of this creation is to provide a supporting metal mask with better support. 3 In other words, the metal mask of this creation includes a metal frame, a metal binding plate and a branch structure. The metal frame has two first side strips facing each other and two first side strips. The metal sheet is stretched over the metal frame. The structure of the support structure is as follows: a first support member has two curved sections and a support section, and the two bends extend from opposite sides of the support section and are bent downward, and the ends thereof are respectively connected to The two first side strips are supported on the bottom surface of the metal sheet. Preferably, the supporting structure further comprises at least one second supporting member having two curved sections and a supporting section extending from opposite sides of the supporting section and bent downward, and the ends are respectively respectively Connected to the two second side strips, the support section is supported on the bottom surface of the first support member. Compared to the prior art, since the first and second support members of the metal mask of the present invention have curved sections connected to the metal frame, they have better reverse support capability to support the metal sheet. Other content and more detailed technical and functional descriptions of this creation will be disclosed in the following description. [Embodiment] The first and second drawings show a preferred embodiment of the supported metal mask 1 of the present invention. The metal mask 1 is mainly used for the evaporation mask in the active array organic light emitting diode (AMOLED) process, but is not limited thereto. The metal mask 1 includes a metal frame 2, a metal sheet 5 stretched over the metal frame 2, and a support structure 3 for supporting the metal sheet 5. Wherein the metal frame 2 includes two first side strips 20 facing each other and two second=two including plural numbers, ... plural (four): ;:::: Example: and: f-support... the system extends from A supporting section 302, the two curved sections are respectively connected with two opposite sides of t=2 and bent toward τ, and the ends thereof are thin with the metal:=:2°. The support section 302 is cut from the lower side of the metal sheet 5, and the first branch support members 35 are smashed in the same manner. In addition, the second 5 series are sighed. Below the first support member 30, and the first support member 35 of the raspberry is connected to the first and second mothers with one or two curved sections (not shown); and the bottom of the support member 352 has a support section 352 3. The two sides of the heart === some of the first pair of sides and are bent downward from the two-phase plant of the branch section, and the end sections are respectively connected to the two side strips 25 of the metal frame 2 (as shown in the first figure) Shown). Thereby, the second branch members can further enhance the supporting ability of the first support members. The material of the support structure 3 may be made of iron-nickel alloy (INVAR) or SUS304 stainless steel. On the other hand, the metal thin plate 5 in the present creation may be a mesh having no mesh and may have a plurality of meshes. Specifically, the metal thin plate 5 may be formed after the welding to the metal frame 2, or the mesh is formed by a laser drilling operation or a meandering method, or a metal thin plate having the meshes may be selected. 5. In any event, the positions of the first support members 30 and the first ones of the floor members 35 are selected to avoid the position of the mesh of the metal sheet 5. Compared with the support structure of the conventional metal mask, the straight strip structure is the same as the first and second support members of the metal mask of the present invention, and the M438484 has the above-mentioned curved section. Strong reverse support capability to grab the sheet metal. In any case, anyone can get enough instruction from the description of the above examples, and understand that the content of this creation is indeed different from the prior art, and it has industrial applicability, and the type needs to be divided and progressive. This creation has indeed met the new i requirements, and the line ^ application.
