Problems solved by technology

[0003] The OLED light-emitting layer uses a fine metal mask (FMM, Fine Metal Mask) to realize the precise preparation of RGB pixels through the evaporation process. The probability of misalignment during the plating process is relatively high, resulting in a failure of the evaporation yield to meet the actual process requirements

Abstract

The embodiment of the invention provides a metal mask plate and a display panel. A first mask region and second mask regions located on the two sides of the first mask region are arranged, the first mask region comprises the pattern region, the first mask region and the second mask regions are distinguished through cutting lines, first stress auxiliary dispersion areas are arranged in the second mask regions, second stress auxiliary dispersion areas are arranged between the pattern region and the cutting lines, so that non-uniform force originally transmitted to the pattern region by a clamping jaw can be absorbed and dispersed to the second stress auxiliary dispersion areas, the stress uniformity and the net stretching precision of the pattern region are improved, the occurrence probability of the deviation phenomenon of the metal mask plate in the RGB pixel evaporation process is reduced, and then the evaporation yield is increased.

Description

technical field [0001] The present application relates to the technical field of display panel evaporation technology, in particular, to a metal mask and a display panel. Background technique [0002] OLED (Organic Light Emitting Display) has excellent properties such as thinness, self-illumination, low power consumption, high contrast and flexible foldability. Strong competition. [0003] The OLED light-emitting layer uses a fine metal mask (FMM, Fine Metal Mask) to realize the precise preparation of RGB pixels through the evaporation process. The probability of misalignment during the plating process is relatively high, which leads to the fact that the evaporation yield cannot meet the actual process requirements. Contents of the invention [0004] Based on the deficiencies of the existing designs, this application provides a metal mask and a display panel, which can improve the uniformity of force in the graphics area and the accuracy of the mesh, and reduce the devia...
