Side-emitting IR LED gives heads up to VR/MR/AR gaming

Miniature PicoLED infrared LEDs from Rohm now include the compact, side-emitting (side view CSL1501RW. It is intended for head-mounted displays, industrial headsets, and virtual reality, mixed reality and augmented reality (VR/MR/AR) gaming systems.

VR/MR/AR technology is being increasingly adopted in headsets and head-mounted displays in a variety of gaming systems. The ability to simulate 3D space and project data in the real world has also expanded VR/MR/AR applications in the industrial sector.

IR LEDs are used for eye tracking with accelerometers for detecting body movement.

The miniature, side-firing, IR LED is optimised for compact mobile devices and wearables, advises Rohm.

The CSL1501RW delivers a peak wavelength of 860nm in a small (1.0 x 0.55mm) side-view design that emits light parallel to the mounting surface. In addition to design flexibility, Rohm has manufactured the LED with improved luminous efficiency and has reduced power consumption by over 20 per cent. The device serves as a light source for eye tracking in VR/MR/AR applications that require greater performance.

The CSL1501RW is sampling now, with mass production scheduled for March 2021.

Rohm Semiconductor develops and manufactures a large product range which includes low power microcontrollers, power management ICs and standard ICs, SiC diodes, MOSFETs and modules, power transistors and diodes, LEDs and passives components such as resistors, tantalum capacitors and LED display units and thermal printheads.

Production takes place in manufacturing plants in Japan, Korea, Malaysia, Thailand, the Philippines and China.

Lapis Semiconductor (former OKI Semiconductor), SiCrystal and Kionix are companies of the Rohm Semiconductor Group.

Rohm Semiconductor Europe has its head office near Dusseldorf, Germany, serving the EMEA region.
