Embodiment Construction

[0027] image 3 is one embodiment of an open mask used in some embodiments of the invention as part of a mask assembly for depositing thin films of organic electroluminescent (EL) devices.

[0028] refer to image 3 One embodiment of the opening mask 30 includes a plurality of openings 33 corresponding to a plurality of unit devices to be formed on a motherboard (not shown). Here, the motherboard refers to a substrate on which an organic EL device can be formed using a mask assembly. In some embodiments, after molding using a mask, each unit device is cut from the motherboard by scribing to form one organic EL device.

[0029] In some embodiments of the present invention, the opening mask 30 includes a plurality of ribs 36 that are parallel with respect to each other, arranged with an equal gap between each rib 36 . Ribs 36 in the column direction (according to image 3 Extending in the y-direction of the coordinate system of ), the plurality of ribs 37 are parallel to eac...

Abstract

A mask assembly configured to prevent the mask from being thermally transformed and to maintain gaps between a plurality of divided pattern masks is disclosed. According to one embodiment, the mask assembly comprises: an open mask that has a plurality of first openings arranged in rows and columns; and a pattern mask that comprises a plurality of unit pattern masks. In some embodiments, the ends of the unit pattern masks may be fixed with respect to the open mask, and the unit pattern mask includes a plurality of mask pattern units configured to align with the plurality of first openings of the open mask. In some embodiments, a tensile force is applied to the unit pattern mask(s).

Description

[0001] This application is a divisional application of a patent application with a filing date of November 17, 2005, an application number of 200510123318.X, and a patent application titled “Mask Component and Mask Frame Component Using the Mask Component”. technical field [0002] The present invention relates to a mask assembly for depositing a thin film in an organic electroluminescent (EL) device and a mask frame assembly using the mask assembly. Background technique [0003] Self-emissive organic electroluminescence (EL) devices offer advantages of plasma display panels (PDPs), such as wide viewing angle, high contrast ratio, and fast response speed. Therefore, organic EL devices are considered to be next-generation flat panel display devices. Typically, an organic EL device includes an anode, a cathode, and an organic layer with a light emitting layer between these two electrodes. Since the organic layer is easily affected by humidity and cannot be formed by a common ...
