P‐75: Student Poster: MicroLED Pixel Circuit Capable of Always on Display Mode Operation for Mobile and Wearable Displays

We propose a novel microLED pixel circuit for mobile and wearable displays. For Normal and AOD mode operation, we applied PWM & PAM hybrid driving and PAM driving, respectively. Under the 4‐duty emission condition, we confirmed that the Vth compensation of the PWM unit, and the grayscale express...

Zusammenfassung:We propose a novel microLED pixel circuit for mobile and wearable displays. For Normal and AOD mode operation, we applied PWM & PAM hybrid driving and PAM driving, respectively. Under the 4‐duty emission condition, we confirmed that the Vth compensation of the PWM unit, and the grayscale expression for each mode.
