  • Publication number: 20090146559
    Abstract: This invention provides a top-emission active matrix electroluminecient device including a substrate and a plurality of pixel areas formed within a display area of the substrate. Each of the pixel areas includes at least one sub-pixel area comprising at least, from top to bottom: a first conductive electrode layer, an electroluminecient layer, a second conductive electrode layer, a first reflective layer region, and a second reflective layer region. The first reflective layer region and second reflective layer region overlap each other in part. Some of the light rays emitted from the electroluminecient layer are reflected by the first reflective layer region and second reflective layer region, respectively, and are then directed upwards. The reflected light rays compensate the top-emitting light rays also emitted from the electroluminecient layer, reducing color shifts at different viewing angles due to the micro-cavity effect.

  • Publication number: 20090135211
    Abstract: Image displaying systems comprising a pixel array, a memory, a parameter selector and a compensator. The memory stores compensation parameter sets of a plurality of specific pixels of the pixel array. According to driving signals of the pixel array, the parameter selector determines a target pixel that the system is going to drive, and then determines whether the target pixel is one of the specific pixels andrequires to be compensated for mura defect. When the target pixel is one of the specific pixels and requires to be compensated for mura defect, the parameter selector outputs a memory address for retrieving the corresponding compensation parameter set from the memory. Based on the retrieved compensation parameter set and an original gray level of the target pixel, the compensator generates a compensated gray level to replace the original gray level to drive the target pixel.
