A recipe for a fully-featured affordable headset is what Apple is trying to find, and they’ve given themselves plenty of time to execute what they have in mind, as this headset has reportedly been delayed beyond 2027. What kind of things are they looking at in Cupertino? TheElec reports that Apple wants to change and go for a different kind of screen.
The current Vision Pro uses panels OLED on Silicon (OLEDoS) from Sony, which have an impressive pixel density of 3,391 ppi. But now Apple has to choose between two different technologies.
We have from one side the W-OLED+CF, a white OLED board with a color filter (to form the red, green and blue colors); This is built on a glass plate instead of silicon.
But there are two ways to create the color filter. The more traditional option is to build the color filter on a second sheet of glass. This is established technology, but since an extra piece of glass is involved, it is thicker.
The option that Apple is leaning towards is to create the color filter in the Thin-Film Encapsulation (TFE) of the first sheet of glass, eliminating the requirement for a second sheet.
Here to mention that Samsung uses such technology to make the screens for its foldable phones and indeed Samsung is the top choice for the screen supplier for the cheapest Apple Vision headsets.
But what is there that worries Apple? Although the company’s desire is to have less than half the pixel density of the expensive Vision Pro, 1,500 ppi versus 3,391 ppi, this is still well above the typical density of a foldable display. Looking at the current crop of Z-folds, the densest screen belongs to the Galaxy Z Flip6 at 426 ppi. This is a third of what is needed.
Of course some will say how 1500 ppi is too much for a mobile device and 400+ ppi is enough. But that still means Samsung Display has to develop higher-density panels for the XR headsets. So the solution with two glasses is not completely ruled out yet.
