Abstract

The invention provides a mask plate and a preparation method thereof. The mask plate comprises a supporting bracket, a first film layer attached to the supporting bracket, and a second film layer arranged on the side, away from the supporting bracket, of the first film layer, wherein the outer frame of the second film layer does not exceed the outer frame of the supporting bracket, and the thickness of the second film layer is smaller than that of the first film layer. Due to the fact that the second film layer is arranged on the side, away from the support frame, of the first film layer, evaporation is carried out through the second film layer, and as the thickness of the second film layer is set to be smaller than that of the first film layer, at the moment, the first film layer can support the second film layer to a certain degree, so that the problem that the second film layer is damaged due to the fact that the second film layer cannot support the weight itself is avoided, the purpose of reducing the film thickness reduction area of the mask plate is achieved, and the purpose of reducing a frame of a display panel is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of mask plates, in particular, to a mask plate and a preparation method thereof. Background technique [0002] In the process of preparing the display panel, each layer of organic light-emitting material needs to be evaporated onto the substrate. The evaporation process will use the corresponding metal mask. The mask of the common layer is used to evaporate the organic or metal of the common layer. Material. In order to ensure that the organic material can be accurately vapor-deposited on the corresponding position of the substrate, it is necessary to completely attach the mask to the substrate. In the traditional mask preparation process, the film layer is stretched, and then the stretched net After the process, the stretched film layer on the support frame is welded to the support frame to assemble a complete mask plate, see figure 1 . [0003] like figure 2 As shown, the film thickness reduc...
