1961 hand held color tv?

No doubt, designers could have been working with such devices and speculating about and showing mock-ups of potential applications, but I think that the cover picture from PM was a total "hoax", for several reasons:

1. The circuitry required to operate a color flat tube in 1966 IMHO, could not possibly fit inside that box.

2. The "beach scene" lighting likely would have washed out any CRT display.

3. If the display was transparent and viewable from both sides, as indicated, wouldn't the viewers arm be viewable in the background of the image.

4. The display picture simply looks "too good" ... if Intertel had something that good in 1966, what happened to them?

again, just my 2 cents worth,

I agree, the cover photo not real, just to show the potential. Did you read the full article in my last post?

Just did... looks as if they had some working but crude lab prototypes of a design similar to the Sony "lollipop" CRTs as well as a very cute mock-up of a portable set.
The limited color (2 color) tube might have been workable, but might not have been good enough to generate much interest and investment capitol for production start up costs.

interesting,

Viewable from both sides makes sense for a 2-color CRT with two phosphors on opposite sides of a glass plate - but the picture would be awfully washed out if you actually left both sides open.
