Abstract: A first arithmetic section is provided that calculates a first time, which is a time period from a transmission timing of a ultrasonic wave to a reception recognized timing at which a wave height value of the ultrasonic wave received by an ultrasonic wave receiving section crosses a predetermined threshold for a first predetermined number of times. A second arithmetic section is provided that calculates a second time as the propagation time of the ultrasonic wave, the second time being a time period from the transmission timing of the ultrasonic wave to a reception confirmed timing, which is a timing after the wave height value has crossed the predetermined threshold for a second predetermined number of times and before the wave height value crosses the predetermined threshold again, wherein the second arithmetic means varies the second predetermined number according to the first time. In this way, coordinates of a pointing device employing ultrasonic wave can be obtained with less error variation.

Abstract: In an image display device which employs pulse width modulation driving, a voltage which is less than a voltage supplied to signal lines is applied to pixel electrodes. Tones are displayed by shifting phases of waveforms of the signal lines and scanning lines, and polarities of pixels in a signal line direction are inverted alternately. This prevents increase in power consumption which is caused by pulse intervals which become too small at high tone levels, in addition to preventing change in tone level due to external factors such as temperature, or signal delays in a driver or wiring.

Abstract: Input position is accurately detected. In an x-detection period of a non-display period, a source drive circuit simultaneously applies to all signal wiring lines a pulse of a peak value proportional to a distance from a gate drive circuit. A coordinate detection circuit obtains an x-coordinate on the basis of a voltage induced at a pen corresponding to the peak value (x-coordinate) of the applied pulse. In a y-detection period, a pulse generation circuit applies one pulse to a common line. The pen detects a potential variation in amplitude proportional to a distance (y-coordinate) from the source drive circuit, generated approximately simultaneously on all the signal wiring lines via a capacitance. The coordinate detection circuit obtains the y-coordinate similarly to the case of x-coordinate detection.

Abstract: A liquid crystal display device has a liquid crystal layer between a glass substrate and a counter substrate. A TFT and scanning lines which control the TFT are provided on the glass substrate. On the counter substrate, a gradation signal line which is connected to a counter electrode applying a voltage to the liquid crystal layer is provided opposite to the scanning lines. A sealing section for sealing the liquid crystal of the liquid crystal layer is provided while enclosing the display area between the glass substrate and the counter substrate. The sealing section has conductive particles. Upper contact pads connected to the gradation signal lines and lower contact pads on the glass substrate are electrically connected via the conductive particles. This realizes a liquid crystal display device with a smaller frame and makes the mounting compact in size without causing poor connection due to line breakage.

Abstract: A wave A1 is used as a signal inputted to a liquid crystal panel via an operational amplifier OP. The wave A1 is a superimposed wave made up of, for example, a first rectangular wave to be the base of a driving signal and a second wave capable of increasing respective amplitudes of the first wave in rising and falling directions. Because a wave A3 is superimposed, using the wave A1 as the driving signal of the liquid crystal panel surely results in increase in a quantity of charges with which respective pixels of the liquid crystal panel are supplied at early stages of writing, more than simply applying the wave A2 to the liquid crystal panel.

Abstract: As a method of driving a liquid crystal display device, the average voltage of reference line drive voltages Vcom for AC-driving a liquid crystal is set higher than the average voltage of signal line drive voltage V0. Moreover, when displaying a plurality of gray scales, the respective voltages are set so that the average voltage of the signal line drive voltages is lowered with a decrease in a voltage difference to be applied to the liquid crystal as an absolute value. In a liquid crystal display device of an opposing signal line structure, a high-quality image display is achieved by compensating for the non-symmetry of the transmissivity of the liquid crystal with respect to positive and negative drive voltages to prevent flickering and image persistence.
