Liquid crystal display and organic light-emitting diode display: present status and future perspectives

Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative study ...

Can this $25 multimeter hold its own against my $250 unit? I put it to the test

For around $25, the Neoteck TS20D is a fully-featured, well-made, and decently accurate tool that will handle most multimeter-related tasks. It's small enough to drop into a pocket or toolbox, durable ...

A refined step-recovery technique for measuring minority carrier lifetimes and related parameters in asymmetric p-n junction diodes

Abstract: Minority-carrier lifetime in a forward-biased asymmetrical p-n junction diode can be measured by observing the time response of the diode to a sudden reversing step voltage. An approximate ...
