High-resolution light-emitting devices for display applications

As carriers of visual information, displays play an indispensable role in our daily life. In recent years, high-resolution (HR) self-emissive displays have been rapidly developed because of the expanding market demand for micro-display products; consequently, research on the improvement of display resolution, material and device structure optimization, the design and development of drive circuits, and various applications of HR display technology has significantly increased. However, there is no comprehensive review of HR light-emitting devices. This review focuses on HR light-emitting technologies. The main contents of the review are as follows: (1) methods for fabricating HR light-emitting devices; (2) processes for fabricating self-emissive displays and other potential fine patterning techniques for the same purpose; (3) the advantages and limitations of these processes; (4) the challenges associated with HR displays. This review can serve as a valuable reference for the development of the mi-crodisplay industry and for studies on microdisplays.
