Micro-LED displays have been recognized as the next-generation display technology. This review focuses on the pixel-driving technology of micro-LED displays. The performance of pixel driving on micro-LED displays is discussed in terms of brightness uniformity, driving speed, grayscale, and frame rate under various driving architectures. Since the memristors possess characteristics similar to those of biological synaptic neurons due to the ion migration mechanism, the neural network approach which combines the memristor arrays with the pixel driving circuit of micro-LEDs could promote the development of smart and efficient displays.
