摘要:
A thin film deposition apparatus and a method of manufacturing an organic light-emitting display device using the thin film deposition apparatus. The thin film deposition apparatus includes a plurality of thin film deposition assemblies, each of which includes: a deposition source that discharges a deposition material; a deposition source nozzle unit that is disposed at a side of the deposition source and includes a plurality of deposition source nozzles; a patterning slit sheet that is disposed opposite to the deposition source nozzle unit and includes a plurality of patterning slits arranged in a first direction; and a barrier plate assembly that is disposed between the deposition source nozzle unit and the patterning slit sheet, in the first direction. The barrier plate assembly includes a plurality of barrier plates that partition a space between the deposition source nozzle unit and the patterning slit sheet into a plurality of sub-deposition spaces.

A mask assembly for a Cathode Ray Tube (CRT) includes a shadow mask with a plurality of beam passage holes, and a frame including a supporting portion with a pair of long sides and a pair of short sides which fix the shadow mask and a strength maintenance portion bent from the supporting portion. The frame includes a plurality of reinforcement indentations formed on a portion of the boundary between the supporting portion and the strength maintenance portion. At least one of the reinforcement indentations satisfies the following condition: S 1 3 ≤ S 2 ≤ 2 3 S 1 wherein S1 represents an area of a triangle defined by a width of the supporting portion including the reinforcement indentation, a width of the strength maintenance portion including the reinforcement indentation and an imaginary line connecting an end of the supporting portion and an end of the strength maintenance portion, and wherein S2 represents a sectional area of the reinforcement indentation.

A tension mask cathode ray tube has a vacuum tube and an inner shield mounted within the vacuum tube to shield the vacuum tube from geomagnetism. A value Br/Hc of the inner shield where Br indicates a residual magnetic flux density and Hc indicates a coercive force is established to be 1.0-2.0 times more than a value Br/Hc of the mask frame. In this structure, the route of electron beams is established to be more precise. Consequently, the purity characteristic and the convergence characteristic are improved while forming a precise raster. In this way, the display screen quality can be enhanced.
