LG thinks it has a solution for the screen-door effect that is common among today's VR headsets, and it wants to patent the technology. Interestingly LG's solution isn't to throw more pixels at the viewer.

The patent, which was published last week and noticed by UploadVR, describes a "light diffusion member" that sits between the display panel and lenses.
