  • Patent number: 10141378
    Abstract: A light emitting device is disclosed, including a first electrode layer, a second electrode layer, and an organic light emitting layer sandwiched between the first and second electrode layers. The second electrode layer is patterned to form a plurality of electrode patterns arranged with different densities. The organic light emitting layer is subjected to a color separation process to form a plurality of monochromatic blocks that correspond to the electrode patterns, respectively. The electrode patterns are divided into a plurality of electrode pattern groups arranged in an alternate manner. The electrode pattern groups display a same image, and a same voltage is applied to the electrode pattern groups at a same time. Alternatively, the electrode pattern groups display different images, and a same or different voltages are applied to the electrode pattern groups at different times. As such, the light emitting device generates grayscale, full-color, three-dimensional or dynamic images.

  • Patent number: 8148971
    Abstract: A layout of a voltage/current reference system is disclosed. A first voltage/current reference circuit (for example, a bandgap reference circuit) and a second voltage/current reference circuit are respectively laid out on either side of a substrate, such as edges or perimeter sides of the substrate. A reference voltage/current is derived by averaging respective output reference voltage/current values of the first and the second voltage/current reference circuits. Accordingly, the noise influence on the voltage/current reference system is minimized.
