Filed:

Feb 9, 2004

Appl. No.:

10/582643

Inventors:

Hironori Ito - Nagoya, JP
Naotaka Koide - Nagoya, JP
Michael Hack - Lambertville NJ, US
Julia Brown - Yardley PA, US

Assignee:

Universal Display Corporation - Ewing NJ
Toyota Industries Corporation - Aichi

International Classification:

H01J 1/62

US Classification:

313504, 313512

Abstract:

Disclosed is a conventional organic light emitting diode (OLED) having one reflective electrode in combination with at least one transparent OLED in stacked configuration functioning as backlighting in a transflective display apparatus such as a liquid crystal display (LCD). Preferably, at least two transparent OLEDs are arranged in a stacked configuration with one conventional OLED, each of the three OLEDs emitting light of a different bandwidth. The reflective electrode located behind the backlight also serves as a reflecting plate for the display. This arrangement enhances reflectivity and permits color sequencing in the transmissive mode, allowing all the components of a full color display (i. e. red, green, blue) to emit through the same pixel without the need for a color filter.

H01J 9/24

US Classification:

313504, 445 24, 362330

Abstract:

Light extraction blocks, and OLED lighting panels using light extraction blocks, are described, in which the light extraction blocks include various curved shapes that provide improved light extraction properties compared to parallel emissive surface, and a thinner form factor and better light extraction than a hemisphere. Lighting systems described herein may include a light source with an OLED panel. A light extraction block with a three-dimensional light emitting surface may be optically coupled to the light source. The three-dimensional light emitting surface of the block may includes a substantially curved surface, with further characteristics related to the curvature of the surface at given points. A first radius of curvature corresponding to a maximum principal curvature kat a point p on the substantially curved surface may be greater than a maximum height of the light extraction block. A maximum height of the light extraction block may be less than 50% of a maximum width of the light extraction block. Surfaces with cross sections made up of line segments and inflection points may also be fit to approximated curves for calculating the radius of curvature.

International Classification:

H01L 51/00
C23C 16/30
H01L 51/52
H01L 51/50

Abstract:

Embodiments of the disclosed subject matter provide systems and methods of depositing a film on a selective area of a substrate. A first jet of a first material may be ejected from a first nozzle assembly of a jet head having a plurality of nozzle assemblies to form a first portion of a film deposition on the substrate. A second jet of a second material may be ejected from a second nozzle assembly of the plurality of nozzle assemblies, the second nozzle assembly being aligned with the first nozzle assembly parallel to a direction of motion between the plurality of nozzle assemblies and the substrate, and the second material being different than the first material. The second material may react with the first portion of the film deposition to form a composite film deposition on the substrate when using reactive gas precursors.

Abstract:

Systems and arrangements of OVJP deposition devices are provided, in which one or more organic material crucibles are directly attached to an injection block and a print head without the need for external delivery components such as feedtubes. Each crucible may be hermetically sealed until it is attached to the injection block, allowing for a single device to provide for storage, transport, and deposition of the organic material.
