Abstract

The invention provides a unit mask, a mask component and a method for manufacturing an organic light emitting diode display. The unit mask extends in one direction and is supported by a frame including openings. The unit mask includes: a first fixing part positioned in the opening and fixed to one surface of the frame disposed along the one direction; a second fixing part spaced apart from the first fixing part and fixed to the frame disposed along the one direction. The other surface of the frame; and the mask part held between the first fixing part and the second fixing part by the first fixing part and the second fixing part.

Description

technical field

[0001] The described techniques generally involve a unit mask supported by a frame and a mask assembly. Background technique

[0002] Examples of flat panel displays include organic light emitting diode (OLED) displays, liquid crystal displays (LCD), and plasma display panels (PDP).

[0003] In order to manufacture an OLED display, it is generally necessary to form electrodes in a specific pattern and form an emission layer. The electrodes and the emission layer may be formed using a deposition method using a mask assembly.

[0004] A conventional mask assembly generally includes a frame having an opening and a plurality of unit masks in a stripe shape. Both ends of each unit mask extend corresponding to the opening and are fixed to the frame. The unit mask may include patterned openings corresponding to pixels of the OLED display, so that the OLED display may be fabricated on the mother substrate. The patterned openings of each unit mask may correspond t...
