The Arpara AIO 5K is a standalone virtual reality headset developed by Arpara Technology, launched via Kickstarter in 2021 and released in 2022-2023. Marketed as the world's first all-in-one VR device with dual Micro-OLED displays and Pancake optics, the Arpara AIO 5K features dual 1.03-inch 2560 × 2560 resolution Micro-OLED panels delivering a combined 5K × 2.5K (5120 × 2560) viewing resolution with exceptional 3514 PPI pixel density and 32 PPD (pixels per degree). The Pancake lens system achieves an optical group thickness of just 10-20mm—eliminating distortion and chromatic aberration while enabling a compact form factor that's approximately half the size of competing VR devices. Weighing only 380 grams (or 200g for the tethered PC VR version), the AIO 5K is among the lightest standalone VR headsets in its class. Powered by the Qualcomm Snapdragon XR2 processor with 6GB RAM, the headset features a 95° field of view, inside-out 6DoF tracking via four cameras with millimeter-level positioning accuracy across a 10m × 10m spatial range, hand tracking support, and DCI-P3 90% color gamut coverage. The unique 15° upward-sloping head strap design provides superior comfort, while active cooling prevents fogging. The AIO 5K supports SteamVR content via wired or wireless arpStreaming and is OpenXR compatible with SideQuest collaboration for expanded content access.
