LTPO-TFT-Based Pixel Circuit With TFT, OLED, and Supply Voltage Compensation for Enhanced Luminance Uniformity in Variable-Frame-Rate AMOLED Smartwatch Displays

LTPO-TFT-Based Pixel Circuit With TFT, OLED, and Supply Voltage Compensation for Enhanced Luminance Uniformity in Variable-Frame-Rate AMOLED Smartwatch Displays

This work proposes a new pixel circuit using low-temperature polycrystalline silicon and oxide (LTPO) thin-film transistors (TFTs) for use in variable-frame-rate active-matrix organic light-emitting diode (AMOLED) smartwatch displays. The proposed circuit, including seven TFTs and two capacitors, ca...
