Light Emitting Diodes
ROHM’s LEDs utilize original semiconductor technologies and proprietary compounds making them among the smallest, thinnest and most energy efficient in the industry.
LEDs are being used in an increasing variety of equipment making compactness and greater energy efficiency imperative.
ROHM addresses these needs by integrating a new 4-element structure (AlGaInP) in the industry’s smallest package, and by developing the PicoLED™ series of chip LEDs, which are the smallest and thinnest in the industry (1.0x0.6mm, t=0.2mm) and 74% smaller in volume than 1608 packages–which were previously the smallest–with the same level of brightness.
LEDs currently under development include low voltage types optimized for energy conservation, multicolor phosphor products for LCD backlights and illumination and ultra-high bright, high reliability units for automotive applications.

LED Displays
From standard to custom modules, ROHM high brightness LEDs and components are incorporated into every display.
0.3-, 0.4-, and 0.6-inch LED numeric displays are available that incorporate ROHM’s own high luminance 4-element LEDs (AlGaInP). Features include ten times the brightness of conventional products, low power consumption and high reliability. A broad selection of colors is offered making them ideally suited for all types of devices including household appliances and gaming devices.
In addition, ROHM offers dot matrix modules optimized for both consumer and public displays featuring 1024-step RGB color capability for natural, lifelike color.

Laser Diodes
ROHM utilizes the latest device and film technologies in order to produce laser diodes optimized for a diverse market.
In the laser printer segment, ROHM offers low-droop, high output (5mW-10mW) laser diodes that deliver faster speeds.
Internal frame materials and construction have been improved as well. The lineup includes both low and high output types produced with equipment developed entirely in-house resulting in high quality products.

Photo Link Modules and Remote Control Receiver Modules
ROHM IrDA and remote control receiver modules incorporate ICs and optical receiver/transmitter elements for greater compactness and higher speeds.
ROHM develops a high-speed (4Mbps) IrSimple IrDA module that can transfer data 60 to 100 times faster than conventional products while reducing the number of external components required.
Remote control optical receiver modules are available in a compact package that reduces mounting space by half compared with competitive products making them ideal for compact devices and high density sets such as video cameras, gaming devices and car navigation systems. In addition, stable light reception is ensured – even under direct sunlight (100,000lux when irradiated at an angle of 45º with respect to light emission).
