Google's first foldable could have a disappearing under-display camera

20 May 2021
Google has patented an innovative way of hiding a camera under the screen.

And it is still always better than a regular punch hole or the "see through" underdisplay camera that DO leave a visible spot which is bot visible AND lower quality.
I think making it a square will make it cheaper to produce.

Otherwise, you want a phone with no front camera at all or a pop up.

obviously the square will be visible and ugly, they should make it a circle to be able to sell it

I really love that rype of look withount any hole and also notch on display of mobiles

The phone will be thicckeer. I think

Let's hope it's a lot better than the Axon 20.

But lets see how it will go.

Yeah, they usually don't really innovate much, this is good to see them doing something new!

They have so much money they can buy everything they want even the company who can invent this for them but they invent front camera themselves.
Its really unbelievable.

And because of how simple it is, it isn't expensive at all, it is quite simple, slightly more expensive than the regular punch hole but not much.

It is an existing tech, nothing new or fancy here.

Much bette... moreThe issue is that it will clash with the battery, and it isn't as relevant as you imagine, mainly nowadays with AI that can easily make as if you looked straight to the camera, and the size of a smartphone doesn't really make it that noticeable anyway, there is a small distance between the top of the phone and the center.

Maybe the guy who made the image didn't know what to put on the right image to illustrate the display in normal use.
But it is mainly here as an illustrative purpose anyway, so just think it is someone else taking the phone and using the main camera to take another picture with the main camera?

You can imagine this concept in another way, imagine if rather than the 90° Prism/Mirror, you had a camera with a display on its back that can rotate 180°, in one direction it looks at you, on the other in doesn't, and you see the display on its back.

beep bop boop, 21 May 2021We won Mr. Stark also with this prism method, does that ... moreJ.A.R.V.I.S. is that you?

Yup, like my design showed, and yes I did, and thank you.
And technically, it is a half periscope already, by definition a second mirror would make this Google design a true Periscope, but for Smartphone camera design definition, it already is one.
Of course, it is a simplification as no lenses are laying out, but the goal is to have a continuous variable zoom using a periscope design.
The top handle Standard, Wide and Ultra-Wide and the front facing camera, but apart from that it is a normal zoom.
The other path is different, it is the Wide/Standard to Telephoto Zoom, and the first part of the periscope is made to handle focus control without using an Iris, so it allows deep depth of field with a wide aperture.
It is the ideal representation of what I often say about Telephoto (long focus distance, deep depth of field) that can also double and triple as Portrait (short focus distance and depth of field) and Macro (super short focus distance and depth of field) should be on Smartphones.

Of course, you can also push the periscope to the extreme, like my fictional concept smartphone design :

And note, on the angles, those aren't Prisms on the wrong orientation, but deformable mirrors :

Those have many advantages over lenses, including avoiding chromatic aberration.
Once you understand that if you shrink a light beam, operations made on it have its focal length relative to its new size and not of the front element size, you understand how powerful and useful can be focusing and collimating to control its size :

Nice patent that will not be used.

Unbelieable an overpriced company with trilions of money is inventing something else apart the OS.

foldable + under display

the crease, the immature udc, expensive too
