They Had That Back Then? #3

Today's lesson: Flat Screen TV (this is a long one to make up for not posting anything in a while).

just because they CAN do something doesn't mean that it can be done cheaply enough to make it viable for mass marketing.

The purpose of this was just to show that the technology has been in development for much longer than most people realize. For example, high definition TV was being worked on way back in the 1950s. Philo Farnsworth, one of the inventors of electronic television, was on I've Got a Secret in 1957, and at the end of the interview he mentions that one of the short term goals of improving television is bumping the resolution to over a thousand lines, equivalent to today's 1080p. France even had a working 800 line system at the time, slightly higher resolution than 720p.

Also, while most of these were just barely working prototypes or concepts, the final example is more advanced than you may think. If it isn't entirely clear, that isn't an LCD TV like the rest of them, it is actually a completely flat picture tube. I'm still somewhat confused about the details, but I think it is equivalent to a large number of short and wide picture tubes stacked on top of each other, in order to eliminate the protruding electron gun. Although flat screen TVs are very popular right now, they still can't approach CRT TVs in some areas. Therefore, one of the technologies currently being developed to replace the LCD TV, the Surface-conduction electron-emitter display (SED), actually consists of millions of tiny picture tubes making up the pixels on the screen. It can offer the picture quality, contrast ratio, viewing angles, and response times of a CRT TV while at the same time offering the high resolutions, unlimited screen size, and lightness of a flat screen TV. So even though it may seem like some of these abandoned technologies led nowhere, sometimes they were just ahead of their time.

i'm sure much of the technology we take for granted took many years to develop sam. this was a very cool post sweetie!

men do tend to over estimate their assets on a regular basis. 😊

Also, a story about something that you may see ten years later if it all goes well just doesn't sell the magazines, I'd imagine. I don't think you can necessarily pin it all on the engineers...

true enough js, i'm sure there were men on the editorial staff as well. 😉
