摘要： In RGB time division drives, there is capacitor coupling due to the effects of fluctuation in the drain lines, and thus, the image quality deteriorates (lateral smearing), so that the display brightness becomes different from the desired display brightness due to delay in the convergence of the fluctuation of the common potential, and thus, it is a goal to prevent the image quality from deteriorating (lateral smearing). In RGB time division drives, the order of time division is switched for each frame, or in the direction of the horizontal lines.

摘要： A display device having an electrostatic capacity touch panel includes: X electrodes XP and Y electrodes YP which intersect each other via a first insulating layer; and a plurality of Z electrodes disposed in a floating state via a second insulating layer. For the second insulating layer, a material such as an elastic insulating material which changes in thickness by pressing of touch is used. The Z electrode is disposed so as to overlap both one of the X electrodes and one of the Y electrodes. A pad part of the X electrode has a largest area in the vicinity of a thin line part of the X electrode, and a smallest area in the vicinity of the thin line part of the adjacent X electrode. An area of the pad part is reduced as the pad part departs from the thin line part of the X electrode.

摘要： Tonal data of one frame of a video signal is subject to time division into dark subframe tonal data at a low tone and bright subframe tonal data at a high tone to compensate for a lowered luminance in the dark subframe by the bright subframe so as not to change an integrated luminance per one ordinary frame. Subframe tonal data read from a memory is converted into output tonal data constituted of dark subframe tonal data at a low tone and bright subframe tonal data at a high tone, by four arithmetic calculation operations using calculation parameters supplied from a register.

摘要： A TFT element for ambient light detection and a TFT element for temperature detection are connected in series. In a first period, a first switch element is off, and a second switch element is at a hi side, so that a threshold voltage of the TFT element for temperature detection is detected. In a second period, a first switch element is on, and a second switch element is at a low side, so that temperature is detected. In a third period, a first switch element is on, and a second switch element is at a hi side, so that ambient light is detected. An input voltage and a control voltage to each of the TFT elements are set by a voltage controller provided in a drive circuit based on the threshold voltage.
