Driving waveforms of partial writing scheme for FLCD

Displays, 1993
Abstract The authors have developed driving waveforms for a new partial writing scheme. In the new partial writing scheme, the selected pixel which will change its image is rewritten, but the selected pixel which will not change its image is not. However, the driving waveform applied to the selected pixel which will not change its image must give the

Design and development of driving waveforms for AC PDPs

Conference Record of the 2002 IEEE Industry Applications Conference. 37th IAS Annual Meeting (Cat. No.02CH37344), 2003
This paper presents design and development of driving waveforms to improve efficacy, contrast and resolution for AC plasma display panels (PDPs). In the paper, the conventional driving waveforms are first reviewed, and the proposed driving waveforms are then discussed.

Driving Waveform Dependency of Energy Dissipation of Trapped Particles

Latin America Optics and Photonics (LAOP) Conference 2022, 2022
Here, we present a numerical simulation of the trapping of particles in a Paul trap to analyse the impact of exotic driving waveforms to disclose the trapping dynamic and maximize the energy dissipation for applied additional cooling techniques.

Josephson Arbitrary Waveform System with Optoelectronic Drive

2017 16th International Superconductive Electronics Conference (ISEC), 2017
Quantum-accurate arbitrary voltage waveforms have been generated using electrical pulse driven Josephson junction arrays (JJAs) by several groups [1, 2]. An alternative method is to use optoelectronic components to convert the electrical pulse drive into an optical signal which is subsequently converted by a photodiode into an electrical drive signal ...

Bipolar Pulse-Drive Electronics for a Josephson Arbitrary Waveform Synthesizer

IEEE Transactions on Instrumentation and Measurement, 2008
A Josephson arbitrary waveform synthesizer (JAWS) has been developed in order to generate quantum-based ac voltage signals. The key component of this JAWS is a modified commercial 30-Gb/s pattern generator that can generate ternary patterns (containing the values 1, 0, and 1, resulting in bipolar pulses).

Modeling of a linear ion trap with driving rectangular waveforms

Journal of Mass Spectrometry
AbstractWe consider the operation of a digital linear ion trap with resonant radial ejection. A sequence of rectangular voltage pulses with a dipole resonance signal is applied to the trap electrodes. The periodic waveform is piecewise constant, has zero mean, and is determined by an asymmetry parameter : one value is taken on interval and another on ,

Programmed driving waveforms for quick-response liquid powder displays

IEEE Transactions on Consumer Electronics, 2010
A low optical contrast ratio is the major drawback of quick-response liquid powder displays (QRLPDs). In this paper, the electro-optical response of the QRLPD is analyzed, and better optical contrast is found to be obtained if the display is driven by pulse number modulation (PNM). However, PNM driving requires a longer driving duration.

Digitising and measurement of variable-frequency waveforms in thyristor drives

Transactions of the Institute of Measurement and Control, 1985
On-going research within our department concerns the testing of thyristor drives for traction use. As a result of this work it became necessary to digitise the repetitive variable-frequency signals produced by the drives, to obtain by software processing root-mean-square and average values of current and voltage waveforms. This was undertaken primarily

20.2: Drive Waveforms for Active Matrix Electrophoretic Displays

SID Symposium Digest of Technical Papers, 2003
Abstract Microencapsulated electrophoretic (MEP) displays are promising candidates for smart handheld applications, where ease of reading and ultra‐low power consumption are of primary importance. A thorough study of the electro‐optic response characteristics of MEP systems has led to the development of a variety of novel drive ...
