The screen-door effect. It is the most obnoxious problem that can hinder any VR Experience. Simply explained: it is what happens when users can see the gaps between the pixels. Technically speaking, it is when a light-blocking area between the sub-pixels of a display panel is clearly visible. In other words, the effect takes away the Immersive from Immersive Experience.
In a US patent application granted last week, it appears the the South Korean company has technology that combats the “screen-door effect” of VR screens. You didn’t think that LG was just going to sit back while its competitors spearhead VR, did you?
According to Android Headlines: “The patent, which is listed as having been filed in February and published on September 14, outlines how placing a diffuser panel directly in front of the user’s eye can spread out the light from the display panel itself. That diffuser itself is described as being made up of a resin layer shaped into either an “irregular or regular curved shape” or as containing one or more “beads” of resin to emulate the light being bent by a more curved shape. It will also sit very close to the wearer’s eyes in order to prevent the user from being able to perceive it, while the main display is set more farther away, LG revealed. By residing close to the user’s eyes and spreading or bending the light from the display panel, the diffuser should effectively fill in the gaps between pixels with light from the wearer’s perspective.”
While a higher resolution display can alleviate the screen-door effect, it will also drive the price of the headset higher, which is not exactly what the industry wants to hear at this moment.
This tech might show up in the company’s upcoming SteamVR HMD, pictured below. Many pundits had been wondering where this headset was after being incognito for a while. The last time it was seen was during the Gamers Developer Conference 2017. This headset uses their OLED screen with 3.64 inches diagonal viewing and 90Hz refresh rate. It might have received some upgrades since then.
