Cold CRT Guns for Thinner CRTs

Fly writes: "According to EETimes, an Austin startup company is close to producing CRTs with cold-emission electron guns. They claim this will reduce the parts needed for electron guns as well as allow for greater control and deflection of the electron beams leading to thinner CRTs. Their technology uses older chip-manufacturing techniquest to deposit diamond tips for the guns on silicon wafers. They hope to enter the CRT market next year."

CRT has its merits over LCD

[tepes]

CRT emits light, doesn't have to worry about latency and visual memory causing ghosting (a problem, I've heard, with TFT and OLED). CRTs also handle colors better. Some of the comparisons and an overview of LCD technology are at ZDNet and ErgoDynamix

Ghosting was recently solved.

The only flatpanel displays that look as good as a CRT to me are extreamly expensive. All the ones that are of lower cost have that wacky ghosting effect, not as bad as the old dual scan LCD displays, but it's there when playing higher framerate games..

That was recently solved - by remembering the previous frame and computing a voltage that would rapidly force the liquid crystal to the correct transparency rather than feeding it the voltage that would eventuall lead to it stabilizing at the desired transparency and letting it relax to that transparency in its own sweet time. There was an article about it maybe a month ago in slashdot.

Exepct TV-rate LCDs without ghosts as soon as this gets incorporated into the driver electronics - assuming the patent holders don't sit on it.
