  • Publication number: 20120261840
    Abstract: A semiconductor device includes an interposer, a semiconductor chip mounted on the interposer, a first wiring pattern formed on the interposer, the first wiring pattern including a first contact coupled to a bonding wire from the semiconductor chip and a second contact coupled to an external terminal of the interposer, and a second wiring pattern formed adjacent to the first wiring pattern on the interposer, the second wiring pattern including a third contact coupled to another bonding wire from the semiconductor chip and a fourth contact coupled to another external terminal of the interposer. The first contact is closer to the semiconductor chip than the third contact.

  • Patent number: 8009180
    Abstract: A display apparatus includes a display panel; a correcting circuit configured to carry out gamma correction on input gradation data in response to correction data which specifies a shape of a gamma curve to generate output gradation data; and a driving circuit configured to drive the display panel in response to the output gradation data from the correcting circuit. The correcting circuit carries out approximation calculation for the gamma correction based on the input gradation data by using a correction calculation equation whose coefficients are determined based on the correction data, and the correction calculation equation is switched based on a value of the input gradation data and a value of the correction data.
