  • Patent number: 11164505
    Abstract: A display apparatus includes: a display panel; a gate driver that provides, to a plurality of scanning lines, scanning pulse signals for controlling pixel switches to be ON in a selection period corresponding to a pulse width thereof; a data driver that provides gradation voltage signals to a plurality of data lines; and a display controller that provides a modulated clock signal having a frequency that changes at a predetermined rate in one frame period. The gate driver sequentially provides the scanning pulse signals each having a pulse width reflecting to a clock cycle of the modulated clock signal in a predetermined order corresponding to distances from the data driver to the plurality of scanning lines. The data driver provides the gradation voltage signals in the order of providing the scanning pulse signals for every data period corresponding to the clock cycle of the modulated clock signal.

  • Patent number: 7321488
    Abstract: An information processing apparatus such as a tablet PC has a rectangular magnesium body. Molded resin components are attached to the body, and have respective functions and engaging portions for releasably securing the body to a docking unit. The information processing device can be used while it is held with a hand or while it is attached to the docking unit. Molded resin components can make sliding contact with the docking unit, but the magnesium body will not make sliding contact with the docking unit and, therefore, the weak points of the magnesium body can be overcome.

  • Patent number: 5859632
    Abstract: A second group of drive voltages V3 to V5 has a voltage range that is separate from, and does not overlap a first group of drive voltages V0 to V2. The first group of drive voltages V0 to V2 is supplied from first power sources VDD and VSS through operational amplifiers OP1 and OP2. The second group of drive voltages V3 to V5 is set with reference to VEE, and is supplied from the first power sources VDD and VSS through the operational amplifiers OP1 and OP2. Voltage conversion capacitors C11 and C12 are charged by turning on and off a first group of switches SW11 to SW13, and are discharged by turning on and off a second group of switches SW14 to SW16, thus causing the output of the second group of drive voltages V3 to V5 which have references to VEE.
