Microsoft Research puts dual images on LCD screens

How would you like to watch a TV show or a movie on a screen while someone else watches a totally different TV show or movie on the same screen? How about playing a "split screen" multiplayer console game with the same technique? Today, Microsoft Research revealed it has developed a way to use existing LCD screens to show two different images on the same screen, but viewed at different angles.

As first revealed by the Next at Microsoft blog, the technique uses how LCD screens on laptops can show different colors and contrasts, depending on which angle the user views the screen. The software that Microsoft Research has developed allows current LCD screens to show two images or videos, which can change depending on how the LCD screen is angled.

The software uses a random dot pattern to hide images on the screen unless that screen is moved or viewed to the correct angle. This technique can also be used to create a stereo 3D effect without the use of glasses.

While this technology is definitely cool, there's no word on when or even if it will ever make it out of the Microsoft Research labs and into the marketplace as a real product.

Very interesting, but I imagine that regular monitors would still need to be altered to make this affect more substancial although the possible aplications are quick cool. Go MS Research!

I would use this to look at porn on an airplane but have it look like an Excel spreadsheet to others.

Love the idea. LMAO. No more boss key.

Wonder if this could appear in the next Xbox? Would be even cooler if it was in a incremental update. Would be cool for local player games!

Jaguar has had dual view screens in their Nav systems for almost two years. Glad Microsoft finally invented a way to do this.

Um, you do realize the dual view screen in Jags and other '3D' and 'dual view' LCD screen technologies are using specialized LCD screens that various 'hardware' techniques.

Specifically the Jag screen uses a column mask LCD.


The Microsoft technology is using a pixel/subpixel color technique that WORKS ON EXISTING LCD displays.

So, ya Microsoft has invented something new. If you really don't 'get this' give up now.

It looks like one image has really good quality (at least comparatively) while the other has quite low quality compared to the first.

But I can definitely see them taking this idea and building LCD panels specifically for it that fix some of its issues while still "working" on current LCDs.

Only downside: you kinda have to use a panel with poor viewing angles to get this to work..

I was just thinking: "How will this work with my IPS-panel?"

exactly. it's just going to be another gimmick for the mass market

You know, everything has to evolve from something. You never know what the future is going to hold for new ideas. Maybe today you'd have to have a screen with poor viewing angles, but think about 5 years from now. Displays could be made to support this. Imagine if your console could detect if your TV have a dual view display and when you play a two player game it could activate it but at other times it can just act as a normal tv set.

Nice, but ultimately useless, impractical, stuff.

Not really, the Range Rover Evoque (can't remember when they added it) has it already in production. Not sure they did it with collaboration with MS or their own thing.

EDIT: The MS research allows existing common LCDs to enable this, not sure if Range Rovers use a specialized one or not.

unless you have system info on the second viewable part of the screen - battery level / sound volume / network connect. no need to tap anywhere on the screen or stop what your doing to check them, just tilt the screen, check them, and tilt back

"the technique uses how LCD screens on laptops can show different colors and contrasts, depending on which angle the user views the screen." - Typo

This could be very promising especially since there is no need to update current hardware.

I have that tablet pc and I always thought the viewing angle was pretty crappy when looking at it vertically. looks like there's actually an upside to it.

I don't really see the practical use for this though. The viewing two viewing angles are too far apart for 3D, and the image quality of each of the two separate images is pretty bad.

What somebody needs to do is manufacture cheap interlaced polarized film that can be stuck on existing monitors to used with polarized glasses..

Would definitely fix the split screen problem in games where each player needs privacy so the other player can't see what they are doing..

to bad, it took allot of skill to focus on 2 screens at once =p

I was actually thinking of Goldeneye... Quick glances were all you needed..

Buttus said,
would that mean it needs double the refresh rates?

No, it displays just like a normal image. It's just playing off of the differences in color rendering at different angles.
