the technology is fundamentally similar to CRT in terms of electron emission at a phosphor coated screen, true. Then again, you could say plasma uses a phosphor coated screen as well. But neither of those screens is the same as a CRT screen. If you've ever seen a CRT *tube* alone, you may have noticed that it's, well, a tube, with screen permanently attached. Vaccuum inside the tube and all. SED is obviously nothing like this. There is some conceptual similarity, but the parts are very different.
