1961 hand held color tv?

It could have been color, but very unlikely, as convergence of electron beams while bending them would have been practically impossible - plus, there can't possibly be a shadow mask, or it would prevent the beam from hitting the back side. I wonder if the claim of two screens with the beam bouncing from one to the other is a mistake. Much more likely to be a non-aluminized glass plate. The scene changes just as the camera moves from front to back, so you can't see if the image is reversed. Maybe someone who reads Japanese can tell us if the text is backwards.

Edit - look carefully - the image on the front screen is at the surface, while the image at the back is recessed by the depth of the device. This appears to be a single transparent plate.

My guess is the display in the video is designed along the lines of the two color CRT shown in the 1966 magazine shown in this thread.



Speculation:

Sony was know to be experimenting with Index beam televisions in the 70's. Maybe as early as 1967? I read they made a 30 inch index beam prototype set.

Two Watchman style CRT's could have been placed back to back in that box.

Two Index beam style color CRT's could have been placed back to back in that box in the video.

The last photo is a prototype type 8 inch color CRT from Sony. Infromation was published 1968. The other photos show the Sanyo and Sony index beam configuration.

In the video, you can see a lot of reflections. I think I see two different images displayed at the same time, but it's hard to say for sure.

Edit: To correct. From my research material, "Sony has been involved in the development of beam index CRTs since the Chromatron era and has started serious commercialization since the 1970s”.

I can tell you for sure that this Motorola pocket set was never put into production nor intended to be. When I worked in the Advanced Development department in Franklin Park in the early 70's, my boss had it in his desk drawer as a memento. It may have been demoed on a high floor with line-of-sight reception to the downtown stations.

Based on the published specs for the 4 inch color Sony prototype flat index set, it would look similar to the KVX-370. Sony seemed to have gotten the deflection right on the 4 inch b&w watchman. Just wish I could find one if it was released.

Edit: The Panasonic Flatvision sold on EBay in June, 2015. Very rare indeed.

That is part of the 1961 "Sets of the Seventies", a design program RCA did to envision what sets would look like around 1970. It was led by Tucker Madawick. I was aiming to do an article for my radio club, but my mother got sick, then I was taking care of her and my family, then I had a kid, then this, then that. Here's a mockup of the bulletin cover and the first page:

Thank you for posting this. First time I've seen the second photo in color. You say the concepts originated in 1961. That is two years prior to the published magazine cover, Mechanix Ilustrated, May, 1963.

Edit: These two concepts were part of eight concepts in total. Would you happen to have more information about that?
