Abstract: A display has a panel, and first and second electrodes. The first and second electrodes define a matrix of cells on the panel. The second electrodes, which correspond to lines of the cells, are scanned to select the cell lines one by one. The first electrodes are driven to set display data for a selected one of the cell lines. The display also has a sequence setting unit for setting sequences of scanning the second electrodes, and a sequence selection unit for selecting one of the sequences that minimizes the current and power consumption of a first-electrode driver without deteriorating the quality of the displayed images.

Abstract: A wireless input device having an outward appearance resembling a standard ballpoint pen operates as both a standard ballpoint pen or similar writing instrument as well as an input device. The pen includes directional sensors for determining the direction and length of each pen stroke. A transmitter is provided in the pen barrel for transmitting the stroke signals directly to a computer for input and processing each stroke to provide an accurate representation of the pen stroke as it is being made. The transmitter may be a wireless device for transmitting a low frequency radio signal to a receiver associated with the computer. This permits the pen to be utilized anywhere within the transmitting range of the device, and in any orientation, with the computer picking up, processing and storing the signal representing the pen strokes.

Abstract: A correction circuit 50 is provided to correct the luminance shading caused by uneven thickness of the liquid crystal layer in the LCD panel. The correction circuit 50 generates a correction signal obtained by modulating the gradually changing signal with smaller amplitude at positions closer to the center in the horizontal direction of the LCD panel and with smaller amplitude at positions closer to the center in the vertical direction when the signal is seen vertically. The signal in the lowfrequency range components of the video signal is used for such modulation. After addind the correction signal from the correction circuit 50 to the video signal by the adder 51, the signal is processed for AC driving and then supplied to the LCD panel section 10. By thus superimposing the correction signal on the video signal for the LCD panel, the luminance shading can be corrected.

Abstract: A display panel driving system, constituted in such a manner that the occurrence of a display irregularity on the display panel can be suppressed without regard to the characteristics or the driving condition of the display panel, is disclosed. An up-counter counts the number of the picture elements which emit light when the EL display panel is horizontally scanned, and the counting result thus obtained is outputted as an addressing signal to an EEPROM. Stored in the EEPROM are data maps MAP, MAP in which pulse width data are written at a plurality of addresses corresponding to the counting ranges of the up-counter. A signal generation means outputs a blank signal BLK which determines the pulse width of a data voltage on the basis of the pulse width data addressed by the up-counter.

Abstract: In a liquid crystal display device where a TFT is connected to each pixel electrode, a storage capacitor voltage VSC inverted after a fall of a gate voltage VG is applied to a storage capacitor line provided for each gate line. A pixel voltage VP retained in a liquid crystal capacitor is influenced by a rise or a fall of the storage capacitor voltage VSC via the storage capacitor, to then rises or fall. By decreasing the amplitude of a drain voltage VD and utilizing a direct-current voltage as a common voltage Vcom, the device requires less current and power consumption is reduced.

Abstract: A computer input device that comfortably supports the hand of the user while the thumb and fingers are associated with buttons, a trackball, and a scrolling wheel carried on the device. The overall configuration of the device and the arrangement of these actuators permits the user to easily and effectively operate all of the actuators while the hand and arm of the user are in a comfortable position. The device includes a housing having thumb-side and finger-side surfaces. The trackball extends from the thumb-side surface. The finger-side surface includes four input buttons and the scrolling wheel. The thumb-side surface is fairly steep and almost at right angles to the finger-side surface. This helps enable the motion of the thumb to fall along its natural axis of flexion/extension. The thumb-side surface extends above the top of the ball to provide a stop when the thumb is moved inwardly off the ball.

Abstract: An apparatus that includes angle detection sections periodically detecting a point on a panel as angles. An angle storing section stores the angles detected during an immediately earlier Ucycle among angles periodically detected, and an angle choosing section chooses angles which are most adjacent to the angles stored among angles detected during the immediately earlier cycle when a number of angles detected during a present cycle is greater than a number of angles detected during the immediately earlier cycle. A coordinate arithmetic section detects during the immediately earlier cycle coordinates based on the angles chosen. In this apparatus, when the number of angles detected during the present cycle is one greater than the number of angles detected during the immediately earlier cycle for each angle detecting section, the coordinates inputted by an other pointing device can be detected through angles which have not been chosen.
