摘要： In a touch panel capable of detecting the coordinates of two pressed-down points individually at the same time, the coordinates detected while one point is pressed are stored and, if a second point is subsequently pressed, the stored coordinates of a first point are used to identify the coordinates closer to the stored coordinates as the first point and the coordinates of another detected point as the second point, thereby identifying an order in which the two points are pressed. Thereafter, what mouse operation has been executed at the coordinates of the first point is detected based on a positional relation between the coordinates of the first point and the coordinates of the second point, and a result of the detection is output to an application operable through a graphical user interface.

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.

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.

摘要： The display device is provided with X electrodes XP and Y electrodes YP which cross with a first insulating layer in between and a number of Z electrodes which are electrically floating from each other with a second insulating layer in between. The Z electrodes are arranged so that each Z electrode overlaps both an adjacent X electrode and Y electrode. The pad portion of a first X electrode has such a form that the area is maximum in the vicinity of the fine wire portion of the first X electrode and the area is minimum in the vicinity of the fine wire portion of an adjacent second X electrode, and the area of the pad portion is smaller towards the direction in which the distance increases away from the vicinity of the fine wire portion of the first X electrode. A pulse signal is sequentially applied to one set of X electrodes or Y electrodes.
