Launch of Smallest Product "MSL0402RGBU," Realizing High Electrostatic Withstand Pressure
Contributing to the improvement of the design of dot matrix displays

ROHM Co., Ltd. announced that it has developed a reflector-type LED (MSL0402RGBU) for consumer devices, such as dot matrix light sources for wearable devices and entertainment devices, which are becoming increasingly miniaturized.

This product is a reflector-type high-brightness 3-color (red, green, blue) LED that achieves the industry's smallest size (1.8mm x 1.6mm) by applying the miniaturization technology accumulated by ROHM. As a result, it enables high color mixing and high-precision LED expression through high-density mounting.



Recently, LEDs capable of diverse full-color expression are being deployed in a wide range of fields, such as digital signage and entertainment devices that require design capabilities. At the same time, as each application becomes smaller and more functional, market demands for LEDs are increasing, such as enhanced expressiveness, miniaturization, and the realization of long-term reliability.

To date, ROHM has developed the ultra-small mold type "PICOLED™ RGB" and the high-brightness reflector type "SMLV series," and has developed the industry's smallest size reflector-type high-brightness 3-color LED to reflect various market demands.

Applications using conventional dot matrix light sources typically utilized Zener diodes when electrostatic discharge (ESD) countermeasures were required. However, the manufacturer explained that this product uses components with high ESD withstand voltage, eliminating the need for Zener diodes. This prevents the problem of unwanted areas emitting light due to current circulation in the dot matrix circuit, thereby enabling clearer display in applications.

This product began shipping samples (price: 100 yen/unit) in August 2016, and has been mass-produced sequentially with a production capacity of 1 million units since November.
