Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] The manufacturing process of the fine mask 1 is as follows: figure 1 As shown, after the mask strip 3 is manufactured, the mask strip 3 and the mask frame 2 are bonded together on a tensioner to form a fine mask 1 . After the net is stretched, the bonding state of the mask strip 3, for example, whether it is flat or not, will directly affect the vapor deposition effect. The bonding state of the mask strip 3 is also affected by the material properties o...

Abstract

Embodiments of the present invention provide a method and device for acquiring material properties of a mask strip, and a method for manufacturing a mask plate, which relate to the field of display technology and can quickly and easily acquire material properties of a mask strip. A method for acquiring material properties of a mask strip, comprising: making a simulation figure according to a mask strip model, the shape and size of the simulation figure and the repeating unit on the mask strip model are the same; wherein the repeat unit includes at least one evaporated Plating holes; according to the simulation graphics, construct equivalent graphics, the shape of the equivalent graphics is a cuboid; the length, width and height of the cuboid are respectively equal to the length, width and height of the simulation graphics; set multiple sets of test parameters, each set of test parameters Both include the displacement constraint values ​​of all surfaces of the simulated graphics; according to each set of test parameters, extract the reaction force on the surface of the simulated graphics; material properties.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method and device for acquiring material properties of a mask strip and a method for manufacturing a mask plate. Background technique [0002] A core technology for preparing high-quality organic light emitting diode (Organic Light Emitting Diode, OLED) display device is to evaporate organic materials on the glass substrate according to a predetermined procedure by evaporation, and use a fine metal mask (Fine Metal Mask, FMM) The patterns on it form red, green and blue devices. [0003] The structure of the fine mask plate is complex and the cost is high, and its precise design can ensure the product yield. Wherein, the fine mask includes a mask frame and a plurality of mask strips. Contents of the invention [0004] Embodiments of the present invention provide a method and device for acquiring material properties of a mask strip, and a method for manufacturing a m...
