Publication number: 20160316540Abstract: A method of manufacturing an electroluminescent device including at least one region that is operable to emit light when excited by an electric signal being applied thereto is provided. Layers of electrode material and light-emitting material are deposited to form a multi-layer structure. During deposition, one or more of the layers are at least partially dried or cured before adding a subsequent layer. Once the multi-layer structure is formed, heat is applied to the multi-layer structure to soften one or more of its layers. Thereafter, an optionally non-planar moulding surface is applied to the softened multi-layer structure to form at least one region with substantial two-dimensional curvature. At least one light-emitting layer within said region is operable to emit light in a spatially continuous manner with substantially uniform luminance and chromaticity across said region.Type: ApplicationFiled: December 8, 2014Publication date: October 27, 2016Inventors: SERGIO LOPERA ARISTIZABAL, JOSE MARIA ANACLETO LUZ JUNIOR, PETER LEVERMORE

Patent number: 9450027Abstract: Systems, and methods for the design and fabrication of OLEDs, including large-area OLEDs with metal bus lines, are provided. For a given panel area dimension, target luminous emittance, OLED device structure and efficiency, and electrical resistivity and thickness of the bus line material and electrode onto which the bus lines are disposed, a bus line pattern may be designed to optimize Fill Factor (FF), Luminance Uniformity (U) and Power Loss (PL). Example designs may be to maximize FF, maximize U and minimize PL. or define minimum criteria for U and a maximum criteria for PL, and then to optimize the bus line layout to maximize FF. OLED panels including bus lines with different resistances along the bus line are also described.Type: GrantFiled: December 2, 2014Date of Patent: September 20, 2016Assignee: Universal Display CorporationInventors: Huiqing Pang, Peter Levermore, Emory Krall, Kamala Rajan, Ruiqing Ma, Paul E.

Patent number: 9397312Abstract: Systems and methods for the design and fabrication of OLEDs, including high-performance large-area OLEDs, are provided. Variously described fabrication processes may be used to deposit and pattern bus lines with a smooth profile and a gradual sidewall transition. Such smooth profiles may, for example, reduce the probability of electrical shorting at the bus lines. Accordingly, in certain circumstances, an insulating layer may no longer be considered essential, and may be optionally avoided altogether. In cases where an insulating layer is not used, further enhancements in the emissive area and shelf life of the device may be achieved as well. According to aspects of the invention, bus lines such as those described herein may be deposited, and patterned, using vapor deposition such as vacuum thermal evaporation (VTE) through a shadow mask, and may avoid multiple photolithography steps.Type: GrantFiled: March 7, 2013Date of Patent: July 19, 2016Assignee: Universal Display CorporationInventors: Peter Levermore, Huiqing Pang, Emory Krall, Rajan Kamala, Ruiqing Ma, Paul E.

Patent number: 9293734Abstract: 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 k1 at a point p on the substantially curved surface may be greater than a maximum height of the light extraction block.Type: GrantFiled: December 23, 2010Date of Patent: March 22, 2016Assignee: Universal Display CorporationInventors: Peter Levermore, Emory Krall, Jeffrey Silvernail, Kamala Rajan, Julia J.
