Problems solved by technology

[0003] Continuing from the above, due to the problems in the design and production of the mask, the flatness of the four sides of the current mask frame presents a parabolic function curve similar to an upward opening.
Therefore, during evaporation, the lowest point of the parabola and its vicinity are in a poor state of bonding with the glass, which easily leads to color mixing.

Abstract

The invention discloses a mask plate frame comprising a plurality of sequentially connected borders. The multiple borders are closed to form an opening. The bottoms of the borders are provided with open grooves. The extending direction of the open grooves is the same as that of the borders, and the two ends of the open grooves do not extend to the two ends of the borders. According to the mask plate frame provided by the invention, through the structure design that the bottoms of the borders are provided with the open grooves, the problem that the middles of the borders of the mask plate framedroop can be solved in the evaporation process, the good attaching effect between all positions of the mask plate frame and a substrate is ensured, and the problem of color mixture is avoided. Meanwhile, due to the fact that the border parts of the mask plate frame are cut out to form the open grooves, thus the weight of the mask plate frame is reduced, and the lightweight requirement of an element can be met.

Description

technical field [0001] The invention relates to the field of OLED device manufacture, in particular to a mask plate frame. Background technique [0002] Flat panel display devices mainly include various types such as LCD display devices, OLED display devices, PDP display devices and electronic ink display devices. Among them, OLED display devices have the advantages of thinness, low power consumption, high contrast, high color gamut, and flexible display, and are the development trend of the next generation of displays. OLED display devices can further include PMOLED and AMOLED types, where the implementation of AMOLED display includes the combination of LTPS backplane and fine metal mask (FMM Mask) and the combination of Oxide backplane, WOLED and color filter. The former is mainly used in small-sized panels, such as mobile phones or other mobile devices, and the latter is mainly used in large-sized panels, such as display panels and TVs. Now the combination of LTPS backp...
