Reserrecting this old tread. Found this recently, a working two sided flat screen television on display at a Japan expo in 1967, one year after the Popular Science cover photo and discussed in this thread and 15 years prior to the first Sony flat Watchman CRT. The film is in black and white, but the two sided display could have been in color. The ID plate looks like Sony or Sharp. See the video below.
