摘要： Provided is a touch-panel device capable of detecting a touched position with high accuracy even when a touched area extends off an electrode area. In one embodiment, the touched area is assumed to be, for example, circular in shape. A width in an X direction (overlap width) and a width in a Y direction (overlap width) of an overlap area where the touched area in a circular shape and an electrode area overlap each other is determined based on sensor measured values. When the overlap width and the overlap width are different from each other, it is judged that the touched area extends off the electrode area, and a position of a center of the touched area in the circular shape is calculated as the touched position.

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 data driver circuit is divided into a low potential region, an intermediate potential region, and a high potential region, and relative withstand voltages in the respective regions are set equal to each other. Both of the transmission of a power source voltage to the high potential region from the low potential region and the transmission of video signals are performed via the intermediate potential region. Due to such a constitution, the withstand voltages in the respective regions can be suppressed to low values.
