Latest Patents

Wang's latest patents include a "Light Emitting Diode Driving Method" and a "Light Emitting Diode Driving Method and Driving Circuit." The first patent describes an exemplary LED driving method that is adapted for driving multiple LED strings. Each LED string can consist of a single LED or multiple LEDs connected in series. This method involves obtaining an initial value of a duty-on period of a driving current to achieve a target accumulative luminosity. The method also includes prolonging the duty-on period to ensure that the accumulative luminosity remains equal to the target for each LED string.

The second patent outlines a LED driving method that utilizes a first pulse width modulation (PWM) signal to determine the brightness of an LED. It involves obtaining a duty cycle of the PWM signal and selectively enabling the LED to operate in either a PWM dimming mode or a direct current (DC) dimming mode. This two-stage brightness control enhances the driving efficiency of the LED.
