Razer first unveiled their open-source VR HMD Dev-Kit, the OSVR, in January 2015. The company has now released an update prototype, and one of the new features is a Full-HD OLED display, which replaces the LCD used in the first iteration. As expected, the OLED offers higher contrast - and lower latency. Razer aims to release the so called Hacker Developer Kit in June 2015, and it will cost $200.
It's great to see another VR developer opting for OLED displays. We've seen this happen with Oculus Rift and just last week Sony unveiled the latest Morpheus OLED prototype. According to Oculus, OLED is a must for VR applications due to the technology's ultra-fast response rate.
