Yellow-green and amber InGaN micro-pixellated light-emitting diode arrays

Abstract

Micro-pixel InGaN LED arrays operating at 560nm and 600nm, respectively, are demonstrated, based on new epitaxial structures. Such devices have applications in areas including bioinstrumentation, visible light communications and micro-displays.

P‐125: Monochromatic Active Matrix Micro‐LED Micro‐displays with >5,000 dpi Pixel Density Fabricated using Monolithic Hybrid Integration Process

“…The miniaturized displays that can be accommodated to those market applications need to meet stringent technical requirements that cannot be fully satisfied by current display technologies such as LCD or OLED technologies. Inorganic compound semiconductor materials based micro-LED micro-displays are viewed as one of the most promising solutions and has gained considerable traction in recent years [1][2][3]. As a self-emissive display technology, micro-LED micro-displays are more compact in size and can provide higher contrast ratio and energy efficiency compared to LCD and LCoS technologies.…”

60.4: A Novel Full‐Color 3LED Projection System using R‐G‐B Light Emitting Diodes on Silicon (LEDoS) Micro‐displays

“…Our group has demonstrated blue and UV active matrix (AM) light emitting diode on silicon (LEDoS) micro-displays by monolithic integration of thousands of LED pixels on a single chip and flip-chip bonded to a CMOS driver [2,3]. In other groups, other colors such as green, amber and red LED microarrays have also been developed using wavelength matched epiwafers or by color conversion method [4,5,6]. However, there is no reported result on simultaneously projecting color images on screen by combining three R-G-B LED micro-display light streams together.…”
