Pixel Circuit With P-Type Low-Temperature Polycrystalline Silicon Thin-Film Transistor for Micro Light-Emitting Diode Displays Using Pulse Width Modulation

P‐73: Student Poster: MicroLED Pixel Circuit Based on Metal Oxide Thin‐Film Transistor with Progressive Emission Method Using Pulse Width Modulation

“…The pulse amplitude modulation (PAM) is generally applied to OLED pixel circuit through saturation current of driving-TFT for gray-level representation [2]. However, it is impossible due to the wavelength shift of microLEDs when PAM is applied to the microLED pixel circuit [3]. Accordingly, the current density of microLEDs should have a constant value regardless of the gray-level and control emission time for gray-level representation.…”

AM Mini-LED Backlight Driving Circuit Using PWM Method With Power-Saving Mechanism

“…he demand for high resolution displays with high contrast ratio has been increasing. Micro-light-emitting diodes (micro-LEDs) and mini-LEDs have attracted substantial attention due to their favorable characteristics, such as selfemission, high efficiency, long lifetime, and high brightness [1], [2]. However, the mass transfer technology for the manufacture of micro-LED displays is associated with numerous challenges because of its low yield and high cost.…”
