Abstract: Aspects of the present invention reduce the number of false positive touch inputs made by a non-stylus object such as the user's finger or hand. When the stylus is located proximate to the touch-sensitive surface, the sensitivity of the surface to non-stylus input is disabled, reduced, or otherwise modified. For example, non-stylus inputs may be ignored while the stylus is within a proximity zone defined near the touch-sensitive surface. Further aspects of the present invention are directed to adjusting the threshold requirements of a non-stylus input depending upon where on the touch-sensitive surface the input is made. Still further aspects of the present invention are directed to calibrating various sensitivity thresholds for non-stylus input, as well as the size and/or shape of the proximity zone.

Abstract: An active matrix electroluminescent display device uses a stepped voltage waveform to the input of the pixel, the stepped voltage waveform being voltage-shifted by a previously stored pixel drive voltage before application to the gate of a drive transistor. The level of the voltage shift determines the duty cycle with which the display element is driven, and thereby controls the grey level output. The height of the steps in the stepped voltage waveform is greater than the voltage width of linear operating region of the drive transistor, so that a selected step of the stepped waveform defines a transition from the drive transistor between fully on and fully off. In this way, the drive transistor is never driven in the linear region.

Abstract: A method for driving a dark ring of a liquid-crystal-on-silicon (LCOS) display is provided to prevent the fringe effect (bright lines) due to the constant voltage difference between the dark ring and the adjoining pixels within the LCOS display. A dark ring is divided into a plurality of portions. The polarity of each portion is controlled in accordance with the polarity of the adjoining pixels within the LCOS display and the scan direction of gate drivers such that the polarity inversion for each portion will coincide with that for the adjoining pixels within the LCOS display so as to avoid the fringe effect (bright lines).

Abstract: A light emitting device is provided which is capable of feeding a reverse current to the defective structural part of a light emitting element, e.g. an organic EL element, without using the power supply voltage as reverse bias. The light emitting device comprises a capacitive light emitting element, e.g. an organic EL element, emitting light upon application of a DC forward voltage. A reverse current can be fed to the light emitting element through a low-resistance defective structural part, for example, only by connecting both electrodes of the organic EL element with the earth after stopping application of the DC forward voltage using a push-pull circuit (5), thereby discharging residual charges of the light emitting element.

Abstract: The data signal line driving circuit of the present invention is arranged so that data signal line groups, each of which is made up of two data signal lines sequentially disposed, are connected to two video signal lines, each of which allows a two-phased video signal to be forwarded. A shift register SR, a drive switching circuit, and a waveform shaping circuit, that constitute a video signal fetching section, collect the data signal line groups via the two video signal lines as a single block. At this time, the data signal lines are respectively driven so as to fetch the video signal from the video signal lines into the data signal lines of the data signal line groups in each block. Thus, in performing multiphase development, it is possible to provide the data signal line driving circuit which can reduce power consumption in low resolution driving compared with a case of high resolution driving.

Abstract: A non-keyboard computer peripheral device represents itself to a host computer as having a keyboard function in addition to representing its actual function. Keyboard status signals are generated by the host computer in response to a user pressing different keys on an actual keyboard. The peripheral device uses the keyboard status signals to identify different peripheral device operations selected by the user. In one example, a radio receiving device represents itself to the host computer as including the keyboard function. Pressing a button on the receiving device causes the receiving device to send a sequence of keystroke commands to the host computer that cause the host computer to initiate software applications and to display operating instructions to a user. A series of further binding operations are then executed in accordance with the displayed operating instructions.
