FED TV and field emission displays are not in the forefront of display technology lately. OLED TV does seem to be making real gains this year with 55″ models from both LG and Samsung promised to consumers. We’ll keep you updated on any changes in FED display technology as they happen.
Actually FED TV is not the only display technology that’s in a coma. SED TV is in a bit of a coma and OLED TV is still emerging from the darkness of development and affordable production techniques. More news as it develops. Thanks for checking in.
FED TV news at last:
(RTTNews) – Wednesday, AU Optronics Corp. (AUO: News ) said it has entered into an agreement with Field Emission Technologies or FET and FET Japan, Inc. or FETJ, to purchase certain assets and to transfer certain technology from FET, a leader in FED or field emission displays technology whose 39.8% of shareholding is owned by Sony Corporation. In the transaction, AUO said it will acquire certain assets that include patents, know-how, inventions, and relevant equipment related to FED technology and materials.
It will be very interesting to see what AU Optronics does with the technology from FET. Stand by for more news.

Just a quick update from CES 2010 in Las Vegas. OLED TV and 3D TV are the main display technologies at the show this year. FED TV or any other form of field emission display is absent.
I’m not expecting too much in the FED TV field in 2010 but I’ll keep this blog going. Thanks.
As 2009 begins FED TV technology may be closer. Field emission display monitors from Ikegami and Astrodesign have been displayed at both Inter BEE 2008 and IBC2008.
“Field emission displays will be the true replacement for high-grade CRT monitors according to Astrodesign, which is previewing a 20-inch FED monitor at IBC in comparison with a high-quality LCD. “It is very similar to CRT because every pixel has its own beam. It creates a very natural look and the motion is very clear,” said Sales Executive Hiroyuki Kuwahara. However, like Ikegami, which also has an FED on show, it will be next year before the display can ship, because the production facility has to be built first, with prices likely to be in the region of Û20,000.” Quote and image from www.ibc.org
OLED TV and SED TV aren’t going to be available anytime soon at a realistic screen size at any price. Field Emission Technologies had announced FED TV production starting in 2009 but considering the recent economic unrest and the problem of financing for their factory acquisition, this may be optomistic.
Production of FED monitors may end up paving the way for consumer models to be delivered by 2010.
Bad news from Field Emission Technologies. Plans to acquire the Pioneer plasma TV factory in Kagoshima, Japan have been put on hold due to difficulty in securing financing.
FET, set up in 2006 between Sony and investment fund Technology Carve-Out Investment LLC to develop ultra-thin displays, had originally planned to buy Pioneer’s factory by the end of March 2009.

Field Emission Technologies has a couple of FED TV|Field Emission displays at FPD 2008 in Japan.
The first display will be the first 240Hz video content of an actual event.
“The nano-Spindt FED will be exhibited as a display monitor in the demonstration of the abovementioned content by KEISOKU GIKEN Co., Ltd.”
Also, in the “High-quality picture 2008” forum at the FPD International 2008, FET will discuss the nano-Spindt FED at Session P-22 with the subject “What high-quality pictures are for each FPD.”

There are many advantages to FED TV or field emission displays over plasma or LCD panels. However, they are very difficult to make. It appears that FET (Field Emission Technologies) has found a solution though.
EE Times published an excellent explanation of FED design and production last month. Please read the full story here. Excerpts are found below.
“No one has been able to mass produce FEDs as a video display due to several technical issues. Manufacturing challenges include problems related to field-emitter structures and the difficulty of attaining high vacuum levels required by FEDs.
FE Technologies claims to have found solutions to the mass-production problem. FEDs are similar to CRTs. Instead of a single electron gun, FE Technologies’ FED uses a large array of cone-shaped electrodes, called “Spindts.” Many Spindts positioned behind each phosphor dot emit electrons through a process known as field emission.”
“A conventional Spindt device was structured by assigning one Spindt per pixel. Therefore, the size of each Spindt needed to be exactly identical, otherwise, the brightness of each pixel became uneven, lowering image quality.
The company corrected the problem by placing multiple numbers of Spindts, called Nano-Spindt Structure, per pixel, thus evening Spindt differentials.”
“Fourteen hundred Spindts are required to keep pixel brightness differentials within 2 percent,” said Hiroyuki Ikeda, general manager of marketing at FE Technologies. Using this structure, the electric current per Spindt decreased while Spindt operating lifetime was improved, the company said.
“The company said it will proceed with the mass production of FED panels using 5,000 glass substrates per month. The initial application for FE Technologies’ 26-inch FED panels will be as “master” monitors, used by TV broadcasters to check picture quality. Neither LCDs nor plasma displays are said to satisfy the high quality standard required by such master monitors.”
An excellent video explanation of how FED TV – Field Emission Displays work and how they are superior to LCD or plasma TV. A must see as it helps explain FED technology in a fairly simple manner.
Although Youtube is not a great source of hi-def video, here’s a comparison between FED (field emission) TV and LCD TV. The frame rate posible with the field emission display practically guarantees no blurring even with the fastest motion.
