Abstract

The invention relates to a mask plate, a mask component and a method for making the mask plate. The mask plate is used for tension welding on a support frame. The mask plate is an electroformed mask plate, and the mask plate includes an evaporation area. , the non-evaporation area and the welding area used for welding with the support frame, at least in the welding area doped with auxiliary ions to improve the welding performance of the welding area, the welding performance of the auxiliary ion is better than that of the electroforming solution for making mask plates Welding performance in anti-corrosion ions. In the mask above, auxiliary ions are doped at least in the welding area to improve the welding performance of the welding area, and the welding performance of the auxiliary ion is better than that of the anti-corrosion ion in the electroforming solution for making the mask. Due to the better welding performance of the auxiliary ions, after doping the auxiliary ions into the welding area, the content of ions with better welding performance in the welding area will be increased, thereby improving the welding performance of the welding area and ensuring the bond between the mask plate and the support frame. welding effect.

Description

technical field [0001] The invention relates to the technical field of display panel preparation, in particular to a mask plate, a mask component and a mask plate manufacturing method. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) adopts a vacuum evaporation technology to prepare an organic light-emitting layer. In the device manufacturing process, the organic material is deposited on the substrate above the evaporation source by high-temperature evaporation. In order to evaporate the organic material to a specific position according to the design, it is necessary to use a mask. The designed effective opening area, through which the organic material is deposited on the back plate to form a preset pattern. [0003] Mask plates are generally prepared by etching process or electroforming process. In actual production, the inventors found that the welding performance of the mask plate prepared by electroforming proces...
