Aperture Ratio Improvement by Optimizing the Voltage Slope and Reverse Pulse in the Driving Waveform for Electrowetting Displays. [PDF]

Micromachines (Basel), 2019
Electrowetting display (EWD) performance is severely affected by ink distribution and charge trapping in pixel cells. Therefore, a multi structural driving waveform is proposed for improving the aperture ratio of EWDs.

Active matrix driven electrophoretic display with in-plane switching layout and driving waveform for reflective and transparent modes

Optics Express, 2023
In-plane switching electrophoretic display (IPS-EPD) is an emerging field of display technology which achieves particles moving horizontally through a lateral electric field. Compared to vertically driven electrophoretic display (V-EPD), IPS-EPD exhibits

Driving complex flow waveforms with a linear voice coil actuator [PDF]

Biomicrofluidics, 2019
Oscillatory and pulsatile fluid flows for use in microfluidic applications were generated using a deformable chamber driven by a low cost linear voice coil actuator. Compliance in the fluidic system originating in the deformable chamber and the fluidic tubing produced a strong frequency dependence in the relationship between the system’s input and the ...

Reliability of a MEMS Actuator Improved by Spring Corner Designs and Reshaped Driving Waveforms [PDF]

Sensors, 2007
In this paper, we report spring corner designs and driving waveforms to improve the reliability for a MEMS (Micro-Electro-Mechanical System) actuator. In order to prevent the stiction problems, no stopper or damping absorber is adopted.

Modeling of a linear ion trap with driving rectangular waveforms [PDF]

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 ,

Driving waveform optimization of electrowetting displays based on pixel’s 2-D model for reducing oil reflux

Optics Express
Electrowetting displays (EWD) are believed to represent a new generation of electronic paper technology with fast responses, high reflectivity, and low power consumption. Despite their bright market prospects, the luminance stability of displays is still

Focal waveforms for various source waveforms driving a prolate‐spheroidal impulse radiating antenna (IRA) [PDF]

Radio Science, 2008
Impulse radiating antennas (IRAs) are designed to radiate very fast pulses in a narrow beam with low dispersion and high field amplitude. For this reason they have been used in a variety of applications. IRAs have been developed for use in the transient far‐field region using parabolic reflectors.

A New Waveform to Solve the Ghosting of BWR EPD [PDF]

Micromachines
The BWR (Black–White–Red) electronic paper display has the advantage of low power consumption and offers a paper-like reading experience. However, refreshing images between black and red can easily produce ghosting images.
