I just received a short email from Toshiba’s SED Project Team. I had requested whatever information they could provide on SED TV specs and features. They recommended the Toshiba SED TV site and also said that they are preparing to produce the first lot of SED TV’s in 2H/’07 (Q2/2007?). Also, they haven’t decided on detailed specifications and features yet.

I imagine that ’2H/’07′ is referring to the second half of 2007, or Third quarter at the earliest. They would be wise to launch sometime early in Q3 as many other TV manufacturers do every year.

Thanks. That makes sense. I wasn’t sure about my interpretation of ‘2H/’07′

I am afraid that this sed technology is taking to long to develop which leads one to beleive that there may be problems associated with it.

It is already developed. What is taking so long is improving manufacturing techniques to make the process of manufacturing cheaper, thereby making the end product cheaper, even though the sed tv parts are inexpensive compared to other tv technologies such as lcd and plasma.

I’m worried this new technology isn’t going to address all the current problems in image presentation.
Sure it’s going to look stunning in terms of deep pure blacks next to bright whites with incredible focus and color accuracy coupled with a wide viewing angle, but what is not being addressed is the refresh rate, vsync, and digital latency.
In other words, used as a computer display, the panel will likely still exhibit the same frame tearing associated with having no vsync like their LCD counterparts. As for latency, even if the phosphors on the screen transition in less then 1ms, how much of a digital delay will exist when filling the panels frame buffer before rasterizing the picture.
Back in the day with large CRT monitors capable of over 160Hz refresh, the graphics adapter provided the option of vsync. With vsync enabled the CRT could display 160 full tear free frames every second resulting in a very fluid picture.
LCD’s on the other hand seem to tear the image horribly when motion is present (that and smear it which will be fixed with SED.) Even with vsync enabled the tear is both visible and distracting. I image this is because the panel doesn’t sync the output rastering process with the input side.
If SED could do this, it would be incredible. That and a futre resistant signaling method supporting higher digital bandwidth for greater resultion capacity and strobe rate.

The technology behind SED allows it to have refresh rates better than CRT, LCD, etc. LCD refresh rate is limited by the rate at which the crystals rotate from full on to full off. Latency is such a problem with LCD that they are always left partially on, which is the reason that they never deliver pure blacks. CRT is limited by the rate at which the plates can scan the electron beam up and down (and side to side) the front of the screen. SED has an emitter for each subpixel !!
Oooohh, I can’t wait.

Well if they referred you to the Toshiba website, they are either providing a canned answer, or they have no idea the plug has been pulled.
This is what the official Toshiba web site has on it:
Sorry, this site has closed
Thank you for using it for a long time. Please continue your favors toward the Toshiba homepage in the future.

Not good….
