ROHM developed the industry, the smallest with reflector, high brightness color LED of "MSL0402RGBU" to achieve miniaturization and high static pressure, help to improve the design of dot matrix displ

ROHM, *1, the world's leading semiconductor manufacturer, has developed LED, MSL0402RGBU, with a reflector for consumer devices such as dot matrix light sources and wearable devices and entertainment products, which are increasingly miniaturized".

"MSL0402RGBU" is a high brightness tricolor (red, green, blue) LED with reflectors, which is the advantage of miniaturization technology accumulated by ROHM over the years, and realizes the smallest size 1.8mm, x, 1.6mm products in the industry. Thus, the high-density mounting can achieve more excellent color mixing performance, and can realize more delicate LED expressive force.

In addition, in the past using dot matrix light source, sometimes need to take prevention measures, the general use of Zener diode, and the "MSL0402RGBU" by using the electrostatic high voltage components, without zener diode can ensure static pressure, prevent unnecessary matrix circuit to produce light, can make the application more vivid.

This product has been on sale since August 2016 (sample price is 100 yen / / no tax). It started in November 2016 and will be put into mass production for 100 million months at a time. The production base is ROHM-Wako Electronics (Malaysia) Sdn. Bhd. (Malaysia).

In the future, ROHM will continue to focus on LED's high brightness, miniaturization, and the expansion of LED product lineup, and continuously contribute to improving the performance of each application.

< background >

In recent years, full-color LED has become more and more popular in a wide range of fields, such as various signs, digital signage and so on, because of its rich expressive power. At the same time, with the development of miniaturization and high performance of various applications, LED is required to be more expressive, and the demand for LED with small, long term and high reliability is increasing. Previously, ROHM has launched a moulding "ultra small PICOLED RGB series and high brightness with a reflector type" SMLV series ", in order to meet the demand of the market, and the development of the industry's smallest mirror high brightness color LED MSL0402RGBU".

1., to the smallest size of the industry, with mirrors, high brightness tricolor LED, to achieve rich and colorful expression

For a long time, the main dimension of LED used in point matrix light source is 3.5mm * 2.8mm, and there are many problems such as display roughness and not colorful display. In this regard, ROHM take full advantage of years of accumulated experience in the field of miniaturization of LED technology, to achieve significant miniaturization, the area of ROHM products in the past reduced by about 70%. Thus, not only ultra fine display, but also a high brightness point matrix light source can be used to improve the expressive power of entertainment equipment, etc..

2., to achieve the industry's top anti vulcanization performance, to help improve reliability

Using a combination of general LED silver frame and silicon resin, affected by sulfur and cigarette gas, silver sulfide and brightness occurred 1 years to reduce about 30% problems, long-term reliability in harsh environment applications. The "MSL0402RGBU" PCB board is partially plated with gold and has been developed not to be vulcanized in silicone. Therefore, long-term reliability of the application can be achieved.

3. ensure static voltage withstand without zener diode

In the past, the use of Zener diodes as an antistatic countermeasure for LED, in the point matrix circuit, may produce a potential supply current to other LED, which led to unnecessary partial luminescence. The "MSL0402RGBU" uses electrostatic, high pressure components, without zener diodes, but also to ensure static voltage, so that products in the dot matrix circuit display performance is superior.
