Abstract: Systems and methods for the design and fabrication of flexible devices, including high-performance large-area OLEDs, narrow border display panels and lighting panels are provided. Various described fabrication- and design-processes may be used to provide the necessary electrical drive to lighting and display panels. Electrical drive may be provided to one or more row- and column-signals by patterning conductive elements near the panel edge. The electrical elements may further be folded over a region near the panel edge back on itself, such that electrical traces may route around the display edge. This may allow the display active area to be substantially the same area as its viewing area, and furthermore may allow pixels go substantially all the way to the edge of the viewing area.

Abstract: This disclosure relates to reduced power consumption OLED displays at reduced cost for reduced information content applications, such as wearable displays. Image quality for wearable displays can be different than for high information content smart phone displays and TVs, where the wearable display has an architecture that in includes, for example, an all phosphorescent device and/or material system that may be fabricated at reduced cost. The reduced power consumption can facilitate wireless and solar charging.

Abstract: The device consists of measuring aspects of human activity or emotion and then communicating that information to an adjustable lighting device or electronic display (as part of a phone, tablet, computer etc) such that the color temperature (or luminance) of the display or lamp is adjusted to match the mood of the user e.g. warmer in the evening close to the end of the day, and cooler in the morning for productivity.

Abstract: Light emitting devices including sub-pixels having different numbers of emissive layers are provided. At least one sub-pixel of a first color may include a single emissive layer, and at least one sub-pixel of a second color may include multiple emissive layers disposed in a vertical stack. Light emitting devices in which different voltages are applied to each sub-pixel or group of sub-pixels are also provided. In some configurations, the voltage to be applied to a sub-pixel may be selected based upon the number of emissive layers in the sub-pixel.

Abstract: The present invention provides an emissive region in organic light emitting devices having a combined emission from at least two emissive materials, a fluorescent blue emissive material and a phosphorescent emissive material. The emissive region may further comprise additional fluorescent or phosphorescent emissive materials. Preferably, the emissive region has three different emissive materials—a red emissive material, a green emissive material and a blue emissive material. Organic light emitting devices incorporating the emissive region provides a high color-stability of the light emission over a wide range of currents or luminances.

Abstract: Described herein are systems, devices, and methods related to adjusting the intensity of specific wavelengths in an illumination panel based on the presence of a person near the panel. By reducing some emitted wavelengths, such as wavelengths associated with blue light, when such wavelengths are not needed or desired, the lifetime and/or efficiency of the lighting panel can be increased. The systems, devices, and methods can be used to reduce energy costs and also to delay the aging of lighting panels.

Abstract: A selective organic emissive material deposition technique is disclosed. A charged organic emissive material may be mixed with a carrier gas and ejected towards a charged intended area of a substrate. The charge for the emissive material may be such that the organic emissive material is attracted to the charged intended area of the substrate and, accordingly, deposited selectively over the charged intended area of the substrate. Additionally, surrounding unintended areas of the substrate may be charged such that the charged organic emissive material is repelled by the unintended areas.
