摘要
We review the emerging mini/micro-light-emitting diode (LED) displays featuring high dynamic range and good sunlight readability. For mini-LED backlit liquid crystal displays (LCDs), we quantitatively evaluate how the device contrast ratio, local dimming zone number, and local light profile affect the image quality. For the emissive mini/micro-LED displays, the challenges of ambient contrast ratio and size-dependent power efficiency are analyzed. Two figure-of-merits are proposed for optimizing the optical and electrical performances of mini/micro-LED displays.
