Photoplate For Oled Deposition Screen
US Patent:
7972442, Jul 5, 2011
Filed:
Jun 27, 2008
Appl. No.:
12/216046
Inventors:
Robert Vaccaro - Greensburg PA, US
Assignee:
Sony Corporation - Tokyo
Sony Electronics Inc. - Park Ridge NJ
Sony Electronics Inc. - Park Ridge NJ
International Classification:
C23C 16/00
US Classification:
118720, 118721
Abstract:
A photoplate for manufacturing a deposition mask that is used to form a matrix of pixel areas used in a display panel. The photoplate comprises a layer of material such as quartz, on which a matrix of pixel etching areas is defined. The pixel etching areas are configured to form pixel areas having a specified separation from each other in a vertical direction. The pixel etching areas on the photoplate include an outer periphery having a generally rectangular shape with elongated corners.
Dimensional Stabilization Of Precision Etched Masks
US Patent:

International Classification:
B05D 5/12, B44C 1/22
US Classification:
427 66, 216 12, 216 41
Abstract:
Dimensional stabilization of a precision etched mask used in the production of organic light emitting diode display panels. This may entail securing a sheet of mask material, and then heating the sheet of mask material to a temperature within a predetermined range for a predetermined amount of time to produce a treated sheet of mask material. The treated sheet of mask material may then be used to fabricate a dimensionally stable precision etched mask, such as by exposing and etching the treated sheet of mask material.
