    摘要: A driving method for local dimming of a Liquid Crystal Display (LCD) device and an apparatus using the same are disclosed. The driving method includes determining a dimming value of each of a plurality of local dimming blocks into which a backlight unit is divided to be driven on a block basis by analyzing input image data on a block basis, detecting a high gray area concentrated with high gray levels from each local dimming block based on the analysis of the input image data, and generating position information about the high gray area according to a distance between the high gray area in the block and an adjacent block, and compensating the dimming value of each of the plurality of local dimming blocks by spatial filtering using a spatial filter having a different filter size or different filter coefficients for local dimming blocks according to the position information about the high gray area in the local dimming block.

    摘要: A semiconductor package includes a metal plate in which one or more openings are formed, the metal plate mounting a semiconductor chip and a printed wire pattern substrate, e.g. a PCB, mounting one or more decoupling capacitors. The semiconductor chip is in direct contact with the metal plate to improve thermal characteristics, and the substrate is supported by the metal plate to increase mechanical stability of the package. The one or more openings in the metal plate accommodate the passing therethrough of plural pins electrically connected via the printed wire pattern substrate to the semiconductor chip. The semiconductor package can be usefully applied to a digital micro-mirror device (DMD) semiconductor package for use in a projection display device.

    摘要: A tape circuit substrate includes a base film with first wiring and second wiring disposed on the base film. The first wiring extends into a chip mount portion through a first side and bends within the chip mount portion toward a second side. The second wiring extends into the chip mount portion through a third side and bends within the chip mount portion toward the second side. The first, second, and third sides are different sides of the chip mount portion. Thus, size and in turn cost of the base film are minimized by arranging wirings within the chip mount portion for further miniaturization of electronic devices, such as a display panel assembly, using the tape circuit substrate.
