Abstract: An adapter holder includes: a mounting portion that detachably mounts an adapter; and an attaching portion that is provided at an opposite side to the mounting portion and is configured to attach to and detach from a separate member.

Abstract: A cable holder includes a holder body, and first and second arm sections that extend from the holder body, and extend in mutually approaching, intersecting directions so as to enclose a housing space for housing a cable. The first arm section has a first oblique section at a tip part thereof, and the second arm section has a second oblique section at a tip part thereof. The first and second oblique sections are inclined in mutually reverse directions, face each other, and are arranged with a gap therebetween.

Abstract: A vertically movable stand for a display device includes: a guide member which is fixed on a base member; a vertically movable member which is vertically movably attached on the guide member, and supports a display; a first friction part which is provided between the guide member and the vertically movable member; and a second friction part which is provided between the guide member and the vertically movable member, at a position displaced from the first friction part toward a side of the base member. A frictional force of the second friction part is set greater than a frictional force of the first friction part.

Abstract: A display driving optimization method and a display driver are provided. The method includes following steps. Previous data and current data of at least a data line of a display panel are estimated to obtain an estimate result. A pre-charge operation or a charge-sharing operation of the data line is enabled or disabled according to the estimation result.

Abstract: A fixing structure for a display panel includes first, second, and third chassis members. The first chassis member includes a first corner securing portion secured to two side surfaces on an outer periphery side of a first corner portion of the display panel. The second chassis member includes a second corner securing portion secured to two side surfaces on an outer periphery side of a second corner portion of the display panel adjacent to the first corner portion. The third chassis member includes an opposing side securing portion secured to a middle portion of a side surface on an outer periphery side of the display panel that opposes a side surface on an outer periphery side that is sandwiched between the first corner portion and the second corner portion. The first, second, and third chassis members are coupled to each other at a back surface side of the display panel.

Abstract: A source driving apparatus of a display is disclosed. The source driving apparatus includes a digital-to-analog converter, a selecting signal generator and a voltage selector. The digital-to-analog converter receives a first part display signal of a display signal and a plurality of gamma voltages and selects a first selecting gamma voltage and a second selecting gamma voltage within the gamma voltages according to the first part display signal. The selecting signal generator receives a second part display signal of the display signal expect the first part display signal and a plurality of pulse-width-modulation (PWM) signals. The selecting signal generator selects one of the PWM signals to generate a selecting signal according to the second part display signal. The voltage selector outputs the first selecting gamma voltage or the second selecting gamma voltage according to a pulse width of the selecting signal.
