Abstract: An image display according to the present invention includes a driving device which performs pulse width modulation drive, restrains power consumption, and produces a good multi-tone display. The image display makes the difference between the scan line voltage and the signal line voltage equal in positive polarity writing and negative polarity writing by which pixels are AC driven, so as to make the on-resistances of transistors equal. This allows a maximum pulse width, the size of switching elements, etc. to be determined first so that they match positive polarity writing in which the resistances value of the switching elements rise. No high frequency clock is required to produce subtle differences of charge ratio in negative polarity writing in which the resistances of the switching elements fall. Power consumption which depends on the clock frequency drops too.

Abstract: A computer keyboard has a grid of conductors forming a plurality of intersections, with force-sensitive resistor (FSR) elements located between the conductors at the intersections. A plurality of keys are located above the intersections and exert force on the conductors and FSR elements during key presses. A resistor network sub-circuit is connected to some of the conductors, and is switchable between low and high resistance values. An Analog to Digital Converter (ADC) is coupled to the resistor network sub-circuit. A microprocessor grounds a conductor and tests another conductor for a threshold voltage level while the resistor network is switched to the high resistance value. The microprocessor switches the resistor network to the low resistance value upon detecting the threshold voltage level and subsequently receives from the ADC a digital value of a voltage on the tested conductor.

Abstract: In a light emitting apparatus, all pixels are fabricated using monochrome light-emitting materials. Since the light transmittances of color filters or color conversion layers are not uniform among red (R), green (G), and blue (B), exact white color cannot be displayed. In the present invention, dots for producing these colors of light, i.e., red (R), green (G), and blue (B), are arranged parallel to writing scan lines and to erasing scan lines. The brightnesses are made uniform by controlling the emission times of the emitted colors of light. According to the brightnesses obtained after passage through the colored layer with the lowest light transmittance, the emission times of colors of light passed through the other colored layers are shortened. Thus, as the brightness differences after passage can be reduced, the light emitting apparatus can display exact white color.

Abstract: A display device with capacitive display pixels, in which a drive scheme is used for capacitive coupling of voltages to enable reduced column voltage swings to be obtained. Each pixel has two storage capacitors. The use of two storage capacitors provides some freedom in the choice of the magnitude of the voltage swing provide on one terminal of one of the storage capacitors. The first capacitor (C1) of all pixels of the display may be grounded, and only the second capacitor (C2) is subjected to changes in voltage to be capacitively coupled to the display cell. This provides a flexible capacitor line drive type scheme.

Abstract: The present invention relates to an information processing terminal that makes it possible to implement a more preferable user interface. A user can input various processes by inclining a PDA (Personal Digital Assistants) 1, while depressing a control button 14.

The PDA 1 generates a clicking feel (feedback) to the user every time it moves the cursor. The present invention is applicable to portable information terminals such as PDAs, and various remote controllers for televisions, game machines and the like.

Abstract: An apparatus of a light source for a liquid crystal display includes two transformers connected between a driver and respective lamps, and a driving signal from a driver is supplied to the lamps through the transformers. Secondary sides of the transformers are connected to each other, and a node between the transformers works as a neutral point in that loads connected to the transformers are symmetrical. The neutral point moves when the symmetry of the load distribution is broken under abnormal operation such as arc generation due to disconnection of the transformers. The movement of the neutral point increases the voltage at the node between the transformers and the driver is shut down when a voltage divided from the voltage of the node is larger than a reference voltage.

Abstract: Application timing of driving pulses for a PDP is controlled so that a flow direction of a discharge current which flows between a first row electrode and a second row electrode of each of row electrode pairs belonging to odd numbered display lines due to the electrical discharge is opposite to a flow direction of a discharge current which flows between a first row electrode and a second row electrode of each of row electrode pairs belonging to even numbered display lines. Furthermore, an impedance of a current channel for the discharge current which flows between the row electrode pair belonging to the odd numbered display line and the electrode driving means is made substantially the same as an impedance of a current channel for the discharge current which flows between the row electrode pair belonging to the even numbered display line and the electrode driving means.

Abstract: A gate line GL is set to an H level to switch on a selection TFT (10) and a short-circuiting TFT (16). A current corresponding to data (data current (negative)) is applied to a data line (Data). In this manner, a current corresponding to the data current flows through a voltage converter TFT (12) and a driver TFT (14) and light is emitted from an organic EL element (50). A gate voltage of the voltage converter TFT (12) and the driver TFT (14) in this process is stored in a storage capacitor (C). Even after the data current is switched off and the selection TFT (10) and the short-circuiting TFT (16) are switched off, the driver TFT (14) continues to apply a current. After a predetermined emission period elapses, an erase line (ESL) is driven to switch an erase TFT (18) on to discharge the storage capacitor (C) and switch the driver TFT (14) off.
