Sep 5, 2017: Rohm introduces 2-color chip SML-D22MUW LEDs delivered in a 1.6×0.8×0.55mm package. It can improve reliability and support high-resolution displays, claims the company.
SML-D22MUW is designed for dual-color numerical displays in industrial equipment and consumer devices. It leverages Rohm’s proprietary technologies and processes to integrate two chips in the same package size as conventional single-color LEDs. This makes it possible to emit multiple colors in a smaller footprint, reducing board space by 35% over standard 1.5×1.3mm 2-color LEDs.
The close configuration of color elements leads to good color mixing properties, making it possible to produce red and green colors as well as many intermediate colors. The devices also feature a backside electrode design that allows mounting in narrow spaces, enabling high-definition display in dot matrix and other applications. The chips draw 5mA per colour, delivering 10 mcd at 570nm (green) and 16 mcd at 620nm (red).
