  • Patent number: 8228280
    Abstract: A reception interface circuit receives a luminance signal for each of multiple colors and a clock signal as input signals. A timing control unit receives the luminance signals received by the reception interface circuit, and controls the timing and format thereof such that they match drivers. A transmission interface circuit transmits the signals generated by the timing controller IC to the drivers. The timing controller IC is included within a rectangular package as a built-in component. The reception interface circuit is arranged on a first short side of the package. The transmission interface circuit is arranged on a second short side of the package. The image data is input via input terminals arranged on the first short side. The output signals of the transmission interface circuit are output via output terminals arranged on the second short side.

  • Patent number: 7939951
    Abstract: A mounting substrate having a structure allowing reduction of the cost and an electronic apparatus formed by surface-mounting a semiconductor device thereon are provided. The mounting substrate is a mounting substrate mounted with a semiconductor device having external terminals alignedly arrayed in the form of a matrix, and includes junctions arrayed on a surface to which the semiconductor device is opposed so that the external terminals are bonded thereto respectively and wires connected to the junctions respectively and extracted out of a region to which the semiconductor device is bonded. The wires connected to inwardly arrayed 4 rows by n columns (n: integer of not less than 5) of the junctions respectively are formed on a first wiring layer. The wires connected to the junctions set in two annular arrays surrounding the outer sides of the 4 rows by n columns of junctions respectively are formed on a second wiring layer different from the first wiring layer.
