In collaboration with Amorphyx, our team set out to assess the feasibility, simulate, and develop a new pixel circuit using pulse hybrid modulation (PHM), which combines pulse width modulation (PWM) and pulse amplitude modulation (PAM). The goal was to improve the efficiency and performance of next-generation OLED displays. Our circuit design incorporates Amorphyx’s thin film devices, specifically their thin film transistors (TFTs) and amorphous metal nonlinear resistors (AMNRs), which offer advantages in speed and device simplicity. We began by studying literature and simulating known pixel circuit designs using Amorphyx’s technology to understand its strengths and limitations. Based on these results, we proposed new designs. We successfully created a pixel circuit focusing on reducing footprint, maintaining the ability to compensate for threshold voltage, and increasing the speed. Some challenges included adapting to new simulation tools and ensuring timing precision at desired speeds. Future improvements could focus on further reducing power consumption and verifying fabrication feasibility. Overall, this project helped bridge academic design with emerging display technologies.
