A mask integration frame and its manufacturing method

Abstract

Embodiments of the present invention provide a mask integration frame and a manufacturing method thereof, which relate to the field of evaporation technology, and can solve the problems caused by mask folds and warpage, replacement or repair of support bars and shielding bars in the prior art. And the relative position of the shielding bar and the mask cannot be adjusted, and the mask integrated frame cannot be cleaned. It includes: a first frame and a second frame, both of which have a hollow area, and the first frame and the second frame are fixedly connected by sleeve; a plurality of mask sheets, and a plurality of mask sheets are sequentially set across In the hollow area of ​​the first frame, and the opposite ends of the mask sheet are fixed on the first frame; the shielding strip and / or the supporting strip, the shielding strip and / or the supporting strip straddle the hollow area of ​​the second frame, and shield The opposite ends of the bar and / or the support bar are fixed on the second frame; wherein, the shielding bar is located in the gap between adjacent mask sheets, and the support bar spans the invalid mask area of ​​the plurality of mask sheets to support multiple a mask.

Description

technical field [0001] The invention relates to the field of vapor deposition technology, in particular to a mask integrated frame and a manufacturing method thereof. Background technique [0002] Currently, the OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panel has been more and more widely used due to its advantages of self-illumination, fast response, high brightness, and thinness. [0003] Wherein, the light-emitting layer in the OLED display panel can be formed by using a fine metal mask (Fine Metal Mask, FMM for short) and through an evaporation process. The fine metal mask board includes a plurality of mask sheets (FMM Sheet), and the mask sheet is provided with a mask pattern. During the evaporation process, multiple mask sheets need to be welded on the frame (Frame) to make a mask. Membrane integration framework (Mask Frame Assembly, MFA) to use. The mask integration frame may further include cover bars arranged between adjacent mask s...
