Abstract
We introduce mini-LED as a promising solution for high dynamic range displays. For mini-LED backlit local dimming LCD, we build a model to simulate the displayed image quality. Through modeling and subjective experiments, we demonstrate that the annoying halo effect could be suppressed to an unnoticeable level by appropriately choosing local dimming zone number and LCD contrast ratio. For mini/micro-LED emissive displays, we discuss the ambient excitation/reflection issues for the two typical full-color solutions and the corresponding size effect. The high luminance and excellent dark state, low power consumption and thin profile, long lifetime and free form factors will make mini- LED displays the next-generation high dynamic range solutions.
