A compact gate driver of oxide thin-film transistors (TFTs) is proposed for Micro-Light Emitting diodes (μLEDs) display with progressive emission pulse-width modulation (PWM), which reuses shift register part and features line-by-line gate scanning (G[n]) and emission control signals (EM[n]) to address switching- and emission-transistors in the μLED pixel. Thus the emission time of μLED is increased by 60% at a refresh rate of 120 Hz, ...
