  • Patent number: 10580987
    Abstract: A method of patterning an organic device includes depositing a first organic functional layer over a device substrate to form a first intermediate structure, the first organic functional layer having a first function such as hole transport or electron transport. The first intermediate structure is coated with a fluoropolymer and treated in a processing agent comprising a fluorinated solvent in which the fluoropolymer is soluble to form a processed intermediate structure. A second organic functional layer is deposited over at least a portion of the first organic functional layer, the second organic functional layer also having the first function.

  • Patent number: 10553145
    Abstract: Disclosed are a pixel structure, a display panel and a driving method thereof, the pixel structure comprising a plurality of alternately arranged first sub-pixel columns and second sub-pixel columns. The first sub-pixel columns comprise sub-pixels of two colors, the second sub-pixel columns are sub-pixel columns of single color, and the number of the first sub-pixel columns is one larger than that of the second sub-pixel columns. The first sub-pixel columns are one column more than the second sub-pixel columns, such that the whole pixel arrangement is a symmetrical arrangement. Therefore, when in mirror display, an image signal processing algorithm consistent with that in normal display can still be maintained.

  • Patent number: 10541276
    Abstract: Disclosed is a double-sided organic light-emitting diode lighting panel. A semitransparent silver film layer is provided between a first light-emitting layer that emits blue light and a second light-emitting layer that emits yellow light. Double-sided light emission of the OLED lighting panel is realized by taking advantage of semi-transparence and reflection properties of the silver film layer. Such a structure is relatively simple, and manufacture costs and manufacture difficulties are reduced. The OLED lighting panel can be used for interior lighting or can be used in places having special needs, and thus application of a double-sided OLED lighting device is widened.

  • Patent number: 10491297
    Abstract: Multiple luminaires are mounted contiguously in a plane, along a straight line or following a one or two dimensional contour, but with a visible periphery between each adjacent pair. A different signal is embedded into the visible illumination emitted by each luminaire, which an image processing module can detect from one or more images captured by a camera. An angle-dependent mask is arranged to cover at least the periphery between adjacent luminaires, such that an appearance of the periphery when viewed from the environment through the mask varies as a function of viewing angle, becoming less visible at greater values of viewing angle (being the angle between a corresponding viewing direction and a normal to the plane, line or contour). The image processing module distinguishes between the different signals based on the periphery being visible when captured from less than a predetermined value of the viewing angle.
