摘要： When a display panel is in contact with the pen tip of an input pen, an infrared receiver and at least two ultrasonic receivers, provided on the display panel, receive respectively an infrared signal and an ultrasonic signal simultaneously transmitted from an infrared transmitter and an ultrasonic transmitter, and computes the contact position of the pen tip on the display panel from a result, containing a time delay, of the ultrasonic receiver receiving the ultrasonic signal with reference to a time when infrared signal is received. The input pen includes a piezoelectric element sensing pen pressure when the pen tip is in contact with the display panel and a microcomputer controlling a infrared transmitter to transmit an infrared signal which changes in accordance with the pen pressure. Thus, in ultrasonic pen input operation, information on the sensed pen pressure is wirelessly transmitted to the device main body, so as to provide a pen input/display device realizing multifunctional, high performance pen input operation based on the pen pressure information in a simple manner.

摘要： 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.

摘要： An illuminating device is provided with a plurality of light source modules (LM) each of which has a light emitting element and a driver circuit for driving the light emitting element, and the illuminating device controls the driver circuit of each light source module individually. All the light. source modules are grouped by having a plurality of light source modules arranged at intervals (d) as one group. A step of lighting light emitting bodies of the light source modules in the same group (for instance, LM (1, 1)·LM (1, 9)) simultaneously under predetermined conditions is performed in turn for all the groups. Based on the obtained light emitting quantity of the light emitting element of each light source module (LM), the driver circuit of the light source module is controlled. Thus, in a backlight device provided with a plurality of illuminating areas, the light emitting quantity in each illuminating area can be accurately corrected in a short time.
