Abstract: A method, system and program for creating child graphical objects in an object oriented graphical user interface. First, the child object is created by copying a set of attributes from a parent graphical object to a memory partition allocated to the first child graphical object. This operation is typically called inheritance or subclassing in object oriented programming. Next, the location data of the first child graphical object is automatically changed from those copied from the parent graphical object. Next, the parent and child graphical objects are displayed on a display in the graphical user interface, the child graphical object being offset in location from the parent graphical object.

Abstract: A thin-film transistor circuit, which is used as a driving circuit for driving pixels in an image display, is constituted of a plurality of thin-film transistors that are formed on an insulating substrate. In each thin-film transistor, a conductive electrode is placed so as to face a gate electrode with a channel region of a polycrystal silicon thin-film that forms an active layer located in between. Here, a constant voltage is applied to the conductive electrode. When threshold voltage is shifted by applying a voltage to the conductive electrode, it is possible to allow the absolute value of the threshold voltage of n-channel-type transistors and the absolute value of the threshold voltage of p-channel-type transistors to become virtually equal to each other.

Abstract: In a liquid crystal display (16) having rows and columns of pixels (22), one or more selected rows of pixels are turned off (put in a standby mode) in a manner that saves power. A row of pixels is turned off by applying to the row a cyclical two-level voltage (BP2) having a magnitude that, when combined with voltages (FP3) applied to columns, results in each pixel in the selected row receiving a combined voltage (BP2-FP3) having a reduced number of transitions (30), having a magnitude that is insufficient to turn on a pixel, and having an average value of substantially zero over a cycle. The method is incorporated in a liquid crystal display apparatus (32) having a mode control (54) for switching selected rows of pixels between an active mode and a standby mode.

Abstract: A plasma-addressed electro-optic display device having a layer of electro-optic material, data electrodes coupled to the electro-optic layer and adapted to receive data voltages for activating portions of the electro-optic layer, and a plurality of plasma channels extending generally transverse to the data electrodes for selectively switching on the electro-optic portions. The plasma channels each contain spaced elongated cathode and anode plasma electrodes and an ionizable gas filling. The cathode and anode electrodes are arranged in groups to reduce the connections required. Reference voltages are applied to the grouped cathode and anode electrodes such that the data voltages required to operate the panel are reduced decreasing vertical crosstalk. Various driving voltage waveforms can be used for further crosstalk reduction, to reduce the number of voltage levels required, and cause the cathode and anode electrodes to exchange roles during operation to extend lifetime.

Abstract: With the use of transfer delay of supersonic wave, an apparatus for measuring a distance and inputting coordinates accurately is implement. When a distance is measured with the use of the transfer of supersonic wave, the transfer delay time is measured at the specified portion of a detected signal. The position of the specified portion to be measured may shift due to the level of the detected signal or noise. The signal obtained by delaying the specified time the envelope of the detected signal is generated. The signal obtained by attenuating the envelope at the specified rate and adding the specified offset is also generated. A gate signal is formed by obtaining the differential of these two generated signals. The delay time is measured during the gate period. With this configuration, the gate-period timing is immune to influences of the signal level and noise, providing highly precise coordinate inputs.

Abstract: The invention relates to a procedure for scrolling some raster scan lines in a window of a screen operated in the graphic-mode of a personal computer. The computer has a processor and a program memory allocated to it as well as a video card connected to the processor via an external bus. The video card has a video memory (RAM), whose memory contents can be presented on the screen. One first line of the raster scan lines to be scrolled, is moved into a raster scan line within the window and is marked with a source-pointer. The raster scan line within a window, in which this line is to be moved into, is marked with a destination pointer. Afterwards, a scroll is performed and repeated until all lines to be scrolled are in raster scan lines of the window. At the same time with the first line, the subsequent third line is also at least scrolled in raster scan lines of the screen window.

Abstract: In a sample and hold amplifier of an analog video display column driver, an operational amplifier output is disconnected from a hold capacitor during the sampling and hold phases. The operational amplifier settling time is not involved in the sampling onto the hold capacitor. The operational amplifier is powered down until the scan line is written to the display. During the sampling and hold modes, no power is consumed. The analog input signal is sampled onto hold and differential capacitors with the operational amplifier disabled. Sampling speed is high since the operational amplifier is not in the loop, and therefore settling need not occur. After one scan line is sampled, a line activation command closes switches and enables the operational column drive amplifiers, thereby enabling the feedback loop of the operational amplifiers.

Abstract: A circuit and method of clearing a thin film transistor liquid crystal display (TFT LCD) when the external power is removed from the liquid crystal display. The screen clearing circuit consists of a power shut-off detection circuit and discharge circuit which operates to discharge the liquid crystal capacitors and support capacitors when the power is removed from the TFT LCD. The circuit consists of a diode and capacitor connected to a PMOS transistor, in which the diode and capacitor detect a power shut-off, thereby turning on a PMOS transistor so as to form a discharge path to ground for the liquid crystal and support capacitors. The TFT LCD screen is cleared when the capacitors are discharged, thereby eliminating a residual image when the power is turned off.

Abstract: Coupled to an error variance circuit 11 is an emission luminance characteristic acquisition circuit 20 that counts up, at a display number counter 21, the display number in the single or plural frames of the respective bits of image data by the counters, M in number, corresponding to said bits, then solves for display area percentage (Sk) dividing, at a display area percentage operation part 22, the display dot number as counted at a display number counter 21, by total dot number, and acquires the luminance deviation characteristic for each bit by means of an emission luminance deviation characteristic measuring part 24. The luminance deviation thus obtained is renewed for each frame and transferred to the error variance circuit 11, and processed for error variance on the basis of the emission luminance characteristic to be output at PDP.

Abstract: An electronics control system for full color and monochrome flat panel displays which automatically accommodates video signals of numerous types and formats, whether interlaced, non-interlaced, composite, or video signals with separated sync signals. Display of such video signals on a wide selection of flat panel display systems also is accommodated. Incoming and output video rates are asynchronous. Plug-in modules allow the system to convert video signals of numerous types and modes for display on any flat panel display system. Images are both automatically, and under user control, up-sized and down-sized, positioned and oriented to fit the flat panel display being used. Color images are automatically reduced to grey scale monochrome when a monochrome flat panel display is being used. Push-pull A/D converter circuitry for digitizing color video signals is used to reduce cost while conserving power.
