ROHM erweitert die Farbauswahl seiner klassenbesten, flachen und kompakten LEDs

Contributes to improved design flexibility in wearables, drones, and other devices


Kyoto and Santa Clara, Calif., – June 29, 2016 – ROHM recently added 7 new colors to its PICOLEDTM series of low-profile, ultra-compact chip LEDs optimized for wearable tech, portable devices, and drones, allowing for greater color expression and improved design freedom.

In recent years the number of applications that have adopted LEDs for lighting in conjunction with a notification function has grown significantly, and greater miniaturization at the component level is increasingly demanded in compact portable equipment. For drones in particular, which are attracting attention in a variety of fields, adoption in new applications is expected, such as utilizing multiple drones that integrate LEDs in visual performances. And due to significant expansion in these markets a number of companies have begun focusing on proprietary designs that require compact LEDs in a wider selection of colors.

In response, ROHM developed the popular SML-P1 series of class-leading thin, compact chip LEDs, utilizing a comprehensive, integrated production system and leveraging its strengths in element technology to eliminate wavelength variations that in the past have proven problematic. As a result, ROHM was able to increase the number of colors from 8 to an industry-leading 15, providing unmatched compatibility.

In addition, combining a lower gold wire loop with a thinner light emitting element (developed using proprietary technology) makes it possible to achieve the thinnest form factor on the market at only 0.2mm, contributing to greater compactness, lower profile and weight saving in mobile applications. Also, taking into consideration usage conditions during reflow allowed ROHM to prevent solder intrusion into the resin by implementing penetration countermeasures within the package itself. This is expected to prevent failures caused by solder infiltration during the customer's soldering process, improving reliability considerably. And going forward, ROHM will focus on strengthening its PICOLEDTM lineup to include high brightness types as well as expand its lineup of RGB LEDs capable of improved color mixing.

Key Features

1. The industry's first 15-color lineup

Seven new intermediate colors have been added to ROHM's existing 8-color lineup, resulting in an unprecedented 15 colors offered - the most in the industry.

2. The world's thinnest form factor (0.2mm) developed using proprietary production technology

External Dimensions

ROHM successfully achieved the industry's thinnest (0.2mm) form factor in a class-leading small package size (1.0x0.6mm), while the lightweight design (0.2mg) meets the need for weight reduction demanded by portable devices and drones. In addition, package miniaturization technology makes it possible to position the light emitting element in a 0.6mmx0.6mm square area, providing square emission characteristics ideal for dot matrix displays.

3. Solder intrusion countermeasures improve reliability

A type of stopper called a ‘solder resist' is implemented before the gold plating process to block the gold pattern (which features good wettability). This makes it possible to prevent solder from penetrating the resin, eliminating failures due to short-circuits and improving reliability considerably.
