Researchers have developed pixels that can not only create images, but also analyse them. In the future, this could lead to ...

A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By applying voltage, this innovative device can freely manipulate the phase and ...

A large percentage of LED drivers offered by many vendors use PWM (pulse-width modulation) intensity control to adjust LED brightness for a wide range of applications. In the PWM drivers, the ...
