Analog PWM Method With Sweep Generation Structure Based on P-Type LTPS TFTs for Micro-LED Displays

This work proposes a novel pixel circuit using analog pulse width modulation (PWM) for micro light-emitting diode (micro-LED) displays. The proposed circuit generates uniform sweep waveforms and driving currents to control micro-LED emission precisely by compensating for threshold voltage (VTH) vari...
