摘要:
A method for driving a thin film EL display device comprising the steps of clamping the Y side scanning electrodes selectively and sequentially to a reference voltage and applying the display voltage selectively from the X side data electrodes. In addition, the non-display voltage which is lower than the display threshold voltage, is applied to the non-selected data electrodes and the non-selected scanning electrodes are floated. This new driving method reduces drive power and widens the device operating voltage range.

A picture displaying method is for displaying a picture by means of a plurality of picture displaying units. A picture signal representing the picture is supplied to each of the picture displaying units. A first picture displaying unit displays a first part of the picture according to the picture signal and produces a start pulse signal after displaying of the first part of the picture. A second picture displaying unit displays a second part of the picture according to the picture signal in response to the start pulse signal.

In a display driving method, after turning a power supply ON, a shift clock CKI2 of a period of 1 &mgr;s is supplied to a shift register in a scanning electrode driving circuit as a shift clock CK2 instead of a shift clock CKN2 of one horizontal synchronous period for n-periods corresponding to n-pieces of scanning electrodes of a liquid crystal, and by an enable signal EN which becomes a “H” level during a period corresponding to n-periods at least, each bit of output data of a shift driver is stopped from transferring to n-pieces of drivers for driving n-pieces of scanning electrodes of a liquid crystal display panel.

A system and method for reducing switching noise generated when an audio signal envelope is abruptly changed provides for gradual change of the audio signal envelope from- one level to another. This gradual change over time in the audio signal envelope can be either near-linear or logarithmic. The system has a volume control register for storing a digital value representative of the envelope magnitude, an up/down counter initialized to a predetermined value, a comparator for comparing the contents of the volume control register and the up/down counter, and a digital-to-analog converter (D/A) which produces the audio signal envelope. The up/down counter output forms the input to the D/A. If the value of the volume control register is larger than the value of the up/down counter then the counter counts up until the values are equal. If the value of the volume control register is smaller than the value of the up/down counter then the counter counts down until the values are equal. If the value of the volume control register is equal to the value of the up/down counter then the counter maintains its state. The clock signal input to the counter is varied so that the user may select between a near-linear change in the D/A output envelope or a logarithmic change.
摘要:
The present invention is to provide a method for uniforming a group of silver halide particles of a silver halide emulsion to be used in a silver halide photographic light-sensitive material into a group of particles which is monodispersive and whose crystal habit is tetradecahedral or octahedral so that the complication and instabilization of the conventional particles can be reduced to be processed. Namely, in a process for growing particles in which a water-soluble silver salt is added to a core emulsion and a silver halide is produced to add to the core, this method is to adjust the pAg values of an emulsion being applied to the abovementioned process to increase by not less than 0.3 multistepwise or continuously.
摘要:
An improved driving system for write operations into shift rows in a multi-row self shift type gas discharge panel. Each shift row is composed of at least one shift channel comprising a regular arrangement of plural shift discharge cells and which is provided with a write electrode which defines a write discharge cell at one end of the shift channel. To the write electrodes of the shift rows, the write voltage pulse is supplied in common. When applying the write voltage pulse to the write electrode of a selected shift row, a shift voltage pulse which is the same in polarity as said write voltage pulse and has an equivalent or greater time width than said write voltage pulse is applied to the shift electrode opposing the write electrodes of the non-selected shift rows, and as a result, erroneous discharges, namely, over-write to the adjacent shift discharge cells, can be avoided by preventing the discharge of the write discharge cells of the non-selected shift rows.

A gas discharge panel self shift drive system is disclosed in which shift electrodes connected to and energized by voltages supplied to a plurality of shift buses, and electrodes connected to a common bus are disposed to intersect each other at right angles with an ionizable gas filled discharge space being defined therebetween. A shift voltage is applied in succession to the plurality of shift buses to shift a discharge spot. In this system, a high voltage pulse of an erasing level is applied to the common bus; a low voltage pulse is applied to the shift buses; and a sustain voltage which is the sum of the high and low voltages is applied to discharge cells at the intersecting points of the shift electrodes and the common electrodes to sequentially shift the discharge spot.
