摘要： An active matrix liquid crystal display (AMLCD) and driving method is disclosed. The AMLCD has matrix-arranged pixel assemblies each having display electrodes. A gate line for carrying gate line pulses is connected to a control port of a row of semiconductor devices, which may be thin film transistors (TFTs). Each TFT has an output port connected to the display electrodes. In addition, a data line is connected to an input port of a column of the TFTs. A bootstrap line is capacitively connected to the display electrodes of adjacent rows. This reduce the number of bootstrap lines to half the number of gate and data lines. A bootstrap pulse timing and generating circuit is connected to the bootstrap line to provide a bootstrap pulse that shifts voltages on the display electrodes in only one direction. The bootstrap pulse has a first edge of a first polarity occurring before or during gate pulses carried on a gate line, and a second edge of a second polarity occurring after the gate line pulses.

摘要： A nondestructive, transparent cursor for AC plasma displays may be superimposed electronically over a displayed image without regenerating the original image each time the cursor is moved. The cursor is displayed by means of a special cursor drive waveform which discharges both previously "on" and "off" cells which form the cursor but permits reversion of the cells to their original state when the cursor drive waveform is removed and the normal sustaining waveform is restored.

摘要： Improved writing and erasing in AC gas discharge display panels is obtained by applying a special normalizing voltage waveform to cause the cells to be in a more standardized state, so that the applied writing and erasing pulses act to cause wall voltage changes which are less sensitive to the cell's recent history. The special normalizing waveform is applied adjacent to the erase pulse and/or to the write pulse and acts to fire the cells in a manner such that there is no loss in the memory state of the cells.

摘要： A distributed Josephson junction logic circuit is disclosed which includes a plurality of serially disposed Josephson junctions in a superconductive wire-over-groundplane environment wherein the latter is terminated at both ends in its characteristic impedance and energized at one end with a constant voltage source. In addition, at least one portion of the wire-over-groundplane transmission line, which is disposed in series with the junctions, is utilized as an output control and has the same steady state current flowing in it as the plurality of Josephson junctions. Utilizing such an arrangement, logic can be performed by means of multiple controls on a single junction as in terminated line logic or by means of several junctions, each with one or more independent controls, in series. The design is such that the switching of any one or more junctions to the voltage state causes a decrease in current from a level which represents a logical "1" to a lesser current which is representative of a logical "0". The resulting logic circuits may be latching or non-latching in character. When both ends of the distributed Josephson junction logic circuit are terminated in the characteristic impedance of the associated transmission line, inputs and outputs can be located at arbitrary points along the transmission line. The terminating resistors, returned at both ends of the line to points of low impedance to ground compared to the impedance of the terminating resistor, absorb transients originating on the power line or at any point along the transmission line. When any one or more of the inputs to such a circuit is a logical "1", at least one of the associated gates switches to the voltage state, reducing the output current to the logical "0" level. In a latching mode of operation, the circuit latches in that state until the gate current is momentarily quenched by reducing the power supply voltage. Thus, each stage normally inverts. The logic operation performed is a positive NOR, which is sufficient to implement any logical function. If desired, two or three controls can be used with some or all of the gates to perform such functions as inhibit, AND-OR-INVERT and majority and threshold logic. Logic circuits utilizing Josephson junctions operating at the gap which provide constant voltages are shown. In addition, circuit arrangements incorporating series-parallel powering circuits and the interconnection of logic circuits between more than one circuit arrangement are shown.

摘要： A light pen detection and tracking scheme for detecting and tracking both "on" and "off" cells with a single cursor voltage waveform in an AC gas discharge display panel. The special cursor voltage waveform is applied to the panel during the sustain cycle, in either a line-by-line or binary scanning fashion, to momentarily fire both "on" and "off" cells so that they may be detected by the light pen without a loss of the memory state of the cells. A cross-hair cursor is automatically displayed at the pen position when the search scan is complete. Since both "on" and "off" cells are detected, the system can respond to pen motion by repeating the search to reacquire the pen, so that no special tracking strategy is needed.
