  • Patent number: 8537527
    Abstract: A mounting board includes two or more metal layers including the outermost metal layer, and a plurality of metal portions, both of which are formed on a substrate. The plurality of metal portions are formed between a first metal layer of the two or more metal layers and a second metal layer of the two or more metal layers, the first metal layer being the outermost metal layer and the second metal layer being different from the outermost metal layer. The second metal layer includes a plurality of first wiring layers extending in a first direction in a plane. The first metal layer is arranged in zigzags in a second direction intersecting with the first direction and includes a plurality of contact pads connected correspondingly to the plurality of first wiring layers through the metal portions.

  • Patent number: 6476779
    Abstract: A video display device is capable of performing a high-speed switching process and preventing video flicker from occurring. The video display device comprises a plurality of display units including a plurality of unit cells. The unit cell comprises a plurality of dots arranged vertically and horizontally each other and divided into a plurality of dot groups. Each dot is comprised of a plurality of display elements. Further, each unit cell is provided with a plurality of memories, a driving means and a switching means. The memories store the video data to be supplied to display elements. The driving means reads the video data corresponding to said dot groups stored in one of the memory and drives the display elements of said dot groups based on the read video data. The switching means switches alternately and successively the dot groups. The memories store the video data successively in a one-frame unit or a one-field unit.

  • Patent number: 6317138
    Abstract: A video display device is described, which is capable of easily correcting variations in luminous brightness of each display element. When a video display part is comprised of a plurality of display units including a plurality of display elements, respective correction data for correcting the variations in luminous brightness of the individual display elements are supplied to memory means. When the display elements are driven, the correction data is supplied to their corresponding drivers. In doing so, the display elements can be driven in a corrected state of the variations in luminous brightness. Even when a unit cell comprising display elements is replaced by another and brightness level is re-adjusted, new correction data relative to it is updated. Said updated correction data may simply be stored in the same memory means. Thus, the variations in luminous brightness can be easily corrected even when the unit cell is replaced by another and re-adjusted.

  • Patent number: 6313816
    Abstract: Light emission data is supplied to an RDATA latch 13R, a GDATA latch 13G, and a BDATA latch 13B and latched as R, G, and B data for every pixel. In an arithmetic operation processing unit 14, an arithmetic operation is performed using the latched R, G, and B data and a chromaticity correction coefficient Cij written in a chromaticity correction coefficient register 16. An arithmetic operation result of the arithmetic operation processing unit 14 is supplied as correction light emission data into a data memory 15 and stored. In a luminance correction data memory 20, luminance correction data is supplied to a constant current driver 18 in accordance with a supplied control signal. The constant current driver 18 drives an LED display 19 in accordance with the correction light emission data and the luminance correction data.
