Annax’s information display used an
SPD-Smart contrast-enhancement filter supplied by Vision Systems.
I have problems imagining how VS would supply millions of contrast filters for smartphones.whoever makes them.

Google's needs are far less than other producers and I suppose VS could contract out the process to a capable party.

Ideas on how any of this might work or could not work?

Lots of rumors, and the junk still won't move.

That HTC group Google just bought?
Here's their 2015 patent for a "portable electronic device" that includes a:

,,,switchable layer ... capable of being switched between a substantially opaque state and a substantially transparent state. The substantially opaque state prevents viewing of the optical element through the switchable layer and the substantially transparent state allows viewing of the optical element through the switchable layer.
Utilizing the portable electronic device of the embodiment of the invention, the optical unit (image sensor or light emitter) is disposed behind the front panel. Additionally, in the substantially opaque state, the optical unit is hidden and invisible. Therefore, the aesthetic appearance of the portable electronic device is improved.

The focus is on a:
.. conventional portable electronic device (smart phone), which comprises a housing, a camera and a flashlight ...However, the camera opening and the flashlight opening may not be aesthetically pleasing when applied to the conventional portable electronic device and thus, decreases the attraction of the portable electronic device to consumers.

An oldie, but a good reminder of how long some of these development cycles take. Since GM (along with everyone else) is headed into EVs.... will that be the breakthrough market..... 30 years ago, they cited the same need that SPD addresses today.

To me, the killer apps are sunvisors, rear side windows and then dynamic glare control on infotainment screens. Sunroofs are just a gimmck AND windshields already use laminated glass. We're getting close, one more model with decent volume gets us to breakeven, but I doubt it's a sunroof that drives demand-- sun visors should do it.

Is it fair or correct to say that reading this patent one possible conclusion is that the patent applies to using "the switchable layer" not to making such a layer?

I doubt LC exists that is clear enough in the 'clear state' to use in front of a camera lense--unless there is some post processing that can correct for the haze.

The clearest LC that I have found is something like 15% haze vs 2% for SPD. We'll never see Dyed LC compete and win against SPD for museum cases....

I think so.

One of our licensees, Smartglass Int wins a big project at Intel HQ...bad news is that it doesn't use SPD.
