Background: Computer usage has rapidly grown. This is because it helps to resolve problems, i.e., encountered in daily life by individuals. Various monitor screens that have been developed affect the userchr('39')s eyes. Screen size is one of the relevant impacts. Thus, this study compared the immediate effects of two computer screen sizes on visual fatigue in Video Display Terminal (VDT) users...

The life of LED driver is mainly dependent on the component used in it. Elimination of electrolytic capacitor is done so that the life of LED driver will increase, if an ac-dc LED driver with power factor correction control is used than the output will be a pulsating current for driving the LED. Since the pulsating current will introduce light flicker that varies double the power line frequency...

Abstract With the rapid development of wind power industry, total installed capacity has increased dramatically worldwide, and a large number installations need to be connected grid. In turbines, voltage flicker due output fluctuations caused by speed changes, application Voltage Source Converter (VSC) cause harmonic richness other quality problems become more prominent. this regard, research i...

This paper proposes a novel pixel circuit and driving scheme that adopts low-temperature polycrystalline silicon oxide thin-film transistors (LTPO TFTs) for mobile devices using active-matrix organic light-emitting diode (AMOLED) displays. The proposed provide uniform luminance render flicker invisible at variable refresh rates (VRRs) from 1 to 120 Hz. Using the with extended compensation time ...
