New Lenovo Tablet Has Projector

Still looking for details about this. I haven't yet gotten confirmation of the projector specs, but a close inspection of the images associated with the article indicate that it's a DLP projector.  

Increasing popularity of pico projection will be good for MicroVision. This appearance does tell us a couple of things that are significant: 

  • Large OEMS are looking at pico projectors.
  • There was enough interest in Lenovo's first Yoga Tablet with PicoProjector that they did it again.
They have adjusted the location of the projector, and bumped up it's power a little bit. 

I'm pretty sure SONY component sales people have knocked on the door of Lenovo.

The Yoga Tab 3 Pro's integrated pico-projector can't be used when you're working in 'stand' mode as it's flush to your desk, but it has a free line of sight to a projecting surface in all other modes.
Lenovo says the Yoga Tab 3 Pro can project images up to 70 inches across -- a considerable increase on the Yoga Tablet 2 Pro's 50 inches. We found its performance to be very impressive. Its 50-lumen brightness makes it viable to use in dimly-lit rooms during the daytime, although in a brightly lit office it will likely suffer from washed-out colours. An app lets you select pre-saved content, and is very easily bypassed.
The projector is undoubtedly the star of the Yoga Tab 3 Pro show, and it should prove useful both at work and at home. It's easy to operate, and is complemented by good battery life and an above-average audio subsystem.

Embedded Projectors on Sony Camcorders will be a LOT better with PicoP

Headed to the local Best Buy with assistance to compare the ShowWx with the DLP projector embedded in a Sony Camcorder.

Apologies for the lack of exactly comparable content, and the non-pure screen. We were trying to be discreet with our informal test. 

The ShowWx is five years old -- compared to last years DLP. The PicoP demo available shown at the Microvision stockholder meeting this year is MUCH better than the projector demonstrated here.

  • The ShowWx is rated at 10 lumens
  • The DLP claims 25 lumens

Clarity of the DLP is pretty good, but it seems kind of "washed out" 
The focus requirement on the DLP is very touchy.

The throw-ratio of the ShowWx is MUCH better. The first picture shows the projectors at the same distance from the viewing surface. The picture of the ShowWx is much larger at the same distance.



Comparing brightness. ("10 lumen" ShowWx on the left "25 lumen" DLP on the right.)



This is the tag for the Sony model tested.


* Thanks Omer!

MVIS at ten VS Texas Instruments DLP at 25 -- MVIS wins, no contest.

Sony is now connected with Microvision. They are employing Microvision's PicoP  and they're using Microvision for a good reason.

I went to look at the embedded projector they are using in one of their camcorder models that is for sale now.

The TI DLP included claims 25 Lumens. I will try and get a video comparison of this with my MVIS ShowWX rated at 10 lumens. The ShowWx is MUCH better than the DLP projector in this camera. I look forward to Sony using PicoP (much better than ShowWx) in many of its products.
