Advances in Lenticular Digital Displays - The ProMa King Tablet

[@ANAVision]

Correction: note that at location 4:04 I make mention of the post card being autostereoscopic and ProMa King tablet being Stereoscopic. This distinction is incorrect. Both are actually autostereoscopic, meaning they can be viewed without headwear/glasses. The distinction I was trying to make here is that one is mutli-view and updates when moving sideways. The other does not update when moving sideways. A more accurate way of distinguishing between the two may be to refer to this as "autostereoscopic" and "automultiscopic"

[@jcjensenllc]

Glad you clarified. I have been in the field for 30+ years and knew you misspoke. I think you coined the term automultiscopic but it is still not accurate. You can't drop 'stereo' in your word as that denotes three dimensionality. In this context, scopic means viewing or observing so multiscopic could mean viewing an animation and is therfore ambiguous. 'Auto' offers no meaning in your word.

[@ANAVision]

@@jcjensenllc, thanks for the clarification. For my interest, in your opinion, what terms could I best use to distinguish between the two?

[@lindilig]

Wow, I really appreciate your practical approach in showing us the specs of this screen. Very clear demonstrations and explanations! I have just discovered your channel today, and I am already hooked up! Looking forward to more videos :) And if you have a way how we viewers can support you (e.g., Patreon) let me know ;)

[@ANAVision]

Thank you so much for the feedback. I hope to get to some more videos up soon. There are tons of ideas for videos I would like to make. Thank you so much for even considering the idea of support and Patreon, I'll have to look into that! At the moment I just have my donate button on my anavision.com.au web site.

[@lindilig]

@@ANAVision Done! It's probably not much...but it's at least a token of appreciation :)

[@ANAVision]

Wow! ​ Linda - Thanks so much!

For this tablet where do you get apps/games that takes advantage of the device? Is there a storefront app like Leia?

[@ANAVision]

Hi, Ray, I've been in touch with ProMa and I've obtained this feedback for you: Thanks for your comment here. We do not suggest 3D game in this tablet, but instead, we have a 3D movie platform in this tablet for about 100 3D movies free of charge, and you can watch 3D film and photo from KZbin and Facebook, on zoom share as well. We already put in several 3D apps in the tablet. Details you may see at proma3d.com

[@desperateBeauty]

thanks for the in-depth review. the big issue is how well the lenticular sheet is aligned to the pixel columns at the factory. I had a Gadmei E8-3D back in the day, I had to swap it out twice due to bad alignment of its parallax barrier which meant the views were always bleeding somewhere, even in the sweet spot.

[@ANAVision]

@desperateBeauty, alignment is indeed extremely important for such displays. I actually kept an eye out for this as even the slightest misalignment could cause issues. I did not find any such issues with the ProMa Tablet. Would be interested to know - in the end did you end up with a Gadmei E8-3D that was aligned? If so, what was the 3D experience like?

[@desperateBeauty]

@@ANAVision yes, the third device was finally perfect at the sweet spot distance (I used a red/cyan test pattern at the time to check, and also told the seller how to use it to verify it before sending it). I guess then the barrier layer was hand aligned and/or their quality control wasn't good enough. But I found the very narrow horizontal sweet spot of the parallax barrier exhausting and so never enjoyed using it. I still have it somewhere.

[@ANAVision]

@@desperateBeauty, quite impressed that you got the seller to use the test pattern.

[@desperateBeauty]

@@ANAVision IIRC it was an Ali Express seller. one of the good ones who wanted to make it right. he didn't understand how to use the pattern correctly on the 2nd device so it was still misaligned, but he got it for the third 🙂. its a very technical thing so I didn't blame him.

[@petepeteseattle]

Might be apples to oranges but would you mind doing a comparison video with LumePad at some point since you have both?

[@ANAVision]

They are quite different as you say. Having said that, I do intend to do a video where I talk on the resolution/views continuum which will including comparisons of various devices including the Lume Pad.

[@petepeteseattle]

@@ANAVision thank you. Looking forward to that video!

[@desperateBeauty]

@@ANAVision I've not seen the Lume, but the Hydrogen is an interesting screen, very easy to view. the synthesised depth maps let it down though, there are too many distracting artifacts, and the screen is prone to ghosting (x-talk) so they limit deviation for a quite shallow effect. you can author for it for the most impact, but other content (including from its own camera) is often too flat to impress.

[@fenghuazhou4537]

We have an expert test report about our ProMa King Tablet glasses free 3D at our website.

[@ANAVision]

​@@petepeteseattle , I hope to get to it soon.

[@user-ke8vk8bo4j]

What app can I use to get the tablet to auto display mpo files in 3D, taken from a Fujifilm w3 3D?

[@ANAVision]

I don't know of a native Android app that would do this, but you can always use Stereo Photo Maker with a screen share like what I did in this video (location: 17:03). Stereo Photo Maker is free and runs on windows and reads mpo files.

[@Jack_Wolfe]

So is this like the Nintendo 3DS screen? with its angle and distance limits?

[@suikasuika4157]

waht's the big differences between this one and the leia lume pad ?

[@ANAVision]

@Suika Suika, the main difference is that the ProMa King has 2 views and the Lume-Pad has 4 in each direction (horizontal and vertical). Having more views gives a holographic type effect where you can move sideways and the scene remains stereoscopic. Just be aware that there is a resolution trade-off.

[@suikasuika4157]

@@ANAVision does that mean the proma have better 3d resolution ?

[@ANAVision]

@@suikasuika4157 The pixel resolution of the underlying screen is exactly the same (1600 x 2560). The resolution per view on Lume Pad is 640 x 400. The ProMa tablet has resolution halved for each eye (1600 x 1280)

[@suikasuika4157]

@@ANAVision sound way better to watch 3D content to have a Proma then, too bad i already got my lume pad, thanks for the information !

[@colinpklam]

Can you show us how to make a video stereoscopically with two cameras

[@ANAVision]

@Lam Colin. Look out for a video that I'm releasing now entitled "How to edit 3D video" kzbin.info/www/bejne/oaeremhsj8x2i68. There I show you how to combine and edit video made with two cameras.

Thank you for your kind words! I really appreciate your feedback and I'm glad that you enjoy my narration :)
