Remarkable brightness in the industry's thinnest package

Overview

ROHM now offers the thinnest LEDs in the industry*. The PICOLED TM series provides impressive brightness in a package only 0.2mm thick. In addition, high reliability is ensured, with no brightness degradation even after 10,000 hours**.
And their small size makes them ideal for use in high resolution high density matrix applications seeking a high degree of expressiveness, such as mobile phone displays.

**Utilizing a high-reliability 4-element (AlInGaP) structure (excluding blue and white LEDs)

Key Feature 1 : The world's thinnest, most compact package

Original high brightness device technology, combined with ultra-fine process technology, are utilized to develop 0.2mm thin LEDs with no brightness degradation compared to conventional products - an unprecedented achievement. Mounting area and volume are reduced 53% and 74%, respectively, over the standard 1608 size, contributing to device miniaturization.
External Dimensions

Key Feature 2 : Supports small-scale customization

●The smaller the LED size the closer they can be placed next to each other, allowing configuration of high density matrixes for greater resolution.
Example: 16pcs × 16pcs = 256pcs

●Customized colors available
Ex: Pink, light blue, purple

Key Feature 3 : New technology utilized for greater reliability

The high reliability 4-element (AlGaInP) structure offers greater reliability with virtually no brightness degradation after 30,000 hours, unlike conventional products that experience a 30% drop in brightness.

Energy-saving PICOLEDTM : PICOLEDTM - eco

ROHM's energy-saving lineup of PICOLEDTM , PICOLEDTM -eco, not only features less volume and mass than conventional products, power consumption is also greatly reduced while still maintaining brightness and wavelength characteristics.
In addition, multiple advanced device technologies are utilized to provide 2.7 times the brightness and 37% less power consumption in the low-current region (1mA), resulting in the brightest, most efficient LEDs in their class.

[Features]

2.7 times brighter at 1mA
Contributes to less power consumption in portable devices for longer battery life
Compact, ultra-thin size: 1.0×0.6mm, t=0.2mm
Available in a variety of colors: red, orange, yellow, and green

Energy-saving PICOLEDs(TM): PICOLED(TM)-eco

The industry's smallest, thinnest multi-color LEDs: PICOLEDTM - Duo and PICOLEDTM - RGB
