Abstract

The invention provides a mask piece. The mask piece comprises an evaporation area and a non-evaporation area, and the evaporation area is provided with a plurality of evaporation openings; and the non-evaporation area is formed adjacent to the evaporation area and provided with an obstructing area and a welding area in a divided mode, the obstructing area is provided with a plurality of obstructing openings, and the multiple obstructing openings are located between the welding area and the evaporation area. According to the embodiment, by forming the obstructing area between the evaporation area and the welding area and further forming the multiple obstructing openings in the obstructing area, in the welding process, when a welding point scatters a large fold into a plurality of small folds, the small folds can be blocked from extending towards the evaporation area, the influence of the small folds extending towards the evaporation area in the welding process on the alignment precisionis relieved to a certain extent, and the evaporation effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a mask sheet and a mask plate. Background technique [0002] Organic Light Emitting Diode (OLED) displays have excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response, flexible panels, and wide operating temperature range. , is considered to be a new application technology for the next generation of flat panel displays. [0003] The full-color display of OLED generally includes R (red) G (green) B (blue) sub-pixels to emit light independently, or a white light OLED combined with a color filter film. Among them, the independent light emission of RGB sub-pixels is currently the most widely used color mode, which utilizes the organic light-emitting materials in the sub-pixel units to emit light independently. [0004] At present, organic light-emitting material layers are generally for...
