Current VR headsets are capable of syncing with the virtual world, but there's still a lot of room for improvement. One of the most frustrating issues users face is the screen door effect, which can break immersion and cause eye strain.
A recently filed patent from LG suggests the company is working on a solution to this problem. The patent outlines an innovative approach that could significantly enhance visual quality in VR headsets.
The screen door effect occurs when the low resolution of VR displays makes individual pixels visible, creating a grid-like appearance. This issue is worsened by the way images are rendered in real time, leading to flickering edges and a lack of smoothness. It’s especially noticeable in fast-paced or detailed virtual environments.
One obvious fix would be to increase the pixel density of the display. For example, a 4K display offers much sharper visuals than a 1080p one, as seen in devices like the PSVR. However, even 4K falls far short of the resolution our eyes can naturally perceive.
Instead of simply boosting resolution, LG’s patent introduces a “light diffusion member†placed between the display panel and the lens. This component spreads the light from the display’s transparent areas into the non-transparent regions, effectively reducing the visibility of the screen door effect and improving overall image quality.
This technology could soon appear in upcoming VR headsets, possibly even in the next generation of SteamVR devices. If it works as described, it could mark a major step forward in VR display technology and make the experience more comfortable and immersive for users. With more companies focusing on visual fidelity, we’re getting closer to a truly seamless virtual reality experience.
