Description:

This paper presents a comprehensive comparison of panel specifications and performance quality (PQ), focusing on key metrics including full grayscale power consumption, pixels per inch (PPI), current error rates in low grayscale, and current pulse decay times. Additionally, we analyze various ?LED driving methods, including Pulse Amplitude Modulation (PAM), Pulse Width Modulation (PWM), and Hybrid PWM Shared (HPS). The study also explores different pixel circuit designs, evaluating PAM, PWM, and HPS. A central theme of this discussion is the necessity and benefits of integrating hybrid driving approaches with stepwise wave techniques, highlighting their potential to enhance display performance and usability.
