Abstract:Display devices have significantly changed our daily life for decades, from the watches, television, to the laptop and smartphone. As the desire of advanced display device with high-resolution, long operation life and lightweight properties, several display techniques have been demonstrated. There are mainly four types of electronic display device: cathode ray tube (CRT), liquid-crystal display (LCD), organic light-emitting diode (OLED), and micro-LED. Due to the different working principles and device structures, each type of display device has its special characteristic properties. The performance of devices could be adjusted through the material selection or device design. With careful device structure regulation, not only the efficiency but also the stability would be improved. Herein, a brief review of innovative strategies towards the structure design is presented.
