Sony Gets Serious With Another Next-Gen Display Tech: FED, Like CRT But Really Thin - Fed - Gizmodo


Hopefully it doesn't have all the problems plasma suffers

[juLZ007]

woo cant wait

how does this differ to SED btw?

i hope FED will display SD content as well as CRT does, so that OLED (which presumably makes a mess of it like LCD does), will have a run for its money

CRT TECH FTW

[Nielo TM]

Actually, T-OLED will be the apex of display panels. For that to happen, Transparent-OLED will need to evolve considerably. When they do, RGB sub-pixels can be stacked on top of each other, rather than next to each other.

In the coming years, FED and FLCD are great alternatives to OLED, but they will not match the performance of a mature standard OLED.

It's quite similar in principle; indeed, arguably, SED is "an FED technology". Both versions use CRT-like phosphors with an individual electron beam for each sub-pixel. The difference between Sony's and Canon's take on it is mostly in the way that the electron beam is generated.

http://en.wikipedia.org/wiki/Surface...mitter_display

http://en.wikipedia.org/wiki/Field_emission_display

From the latter: "Whereas FED uses a 'Spindt tip' semi-conductor or carbon nanotube emitter, with multiple redundant emitters per area of display, SED uses a single emitter based on palladium oxide laid down by an inkjet or silk-screen process."

There is zero chance of that, I'm afraid. The reason CRT does a good job with SD is that it doesn't use fixed pixels. All display technologies for the remotely foreseeable future will use fixed pixels, including SED and FED. However, SED and FED should have all of CRT's other advantages, such as black level, response time, colour and gamma accuracy, and lack of motion artefacts, and none of the disadvantages of bulk or poor geometry.

[Nielo TM]

motion detail will be based on the driving method, in this case, PWM. So it may be equal to plasmas.

In any case, SED and FED have no chance against OLED.

Nice jacket

[Nielo TM]

maybe it's an EM shield LOL

[ktmakwana]

nice!

SED and FED should be far superior to plasma in terms of a lack of motion artefacts. Plasma pixels are either full on or full off, and the perception of brightness is created by flashing them on and off rapidly during the course of a frame, with "brighter" ones being switched on for longer. With SED and FED you can actually control the brightness of the light emitted by each pixel in the same way as CRT does. That should give it CRT-like motion.

[Nielo TM]

when you meant on/off, were you referring to AM?

I know for a fact, PDP uses PWM and so does SED. So in that retrospect, I think the motion detail will be somewhat equal to the PDP. In any case, it really doesn't matter.


Also, CRT's motion detail was actually due to the way it displayed the image


Below the front glass of the CRT lies the phosphor coating. When it’s hit by the electron beam, it becomes ‘excited’ and emits light. The phosphor will continue to emit light for about 1-1.6 milliseconds before it begins to fade, which causes slight flicker but at the same time, it helps to remove the previous image from the eye’s retina. However, just like all phosphor based displays, it was prone to after images.

OLED has motion blur issues, just like LCD. OLED has sample and hold because of active matrix. I really want SED.

[Nielo TM]

If the OLED uses standard AM, then yes, it will have motion blur.


However, the Sony's 11" OLED actually has minor flicker. So either they are using a driver that's is other than AM or they've embedded BFI.


In any case, we have to find that sweet-spot between flicker and motion blur.

What on earth is that guy wearing.

[jendo]

Lol maybe the screens emit dangerous radiation and he is protecting his vital organs.

Does anyone know if these FED SED displays use high voltages and emit x-rays like CRT TVs?

Yes they do use high voltages. The way light is generated is the same in FED/SED as in CRT, i.e. high energy electrons strikes phosphor to produce light. Small quantity of radiation would definitely be emitted. But perhaps they can trim the electron mobility better with a closer emitter than they could with a cathode ray emitter.

AU Optronics Announces Purchase of FED-related assets and technology from Field Emission Technologies

AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) announced today that AUO has entered into an agreement with Field Emission Technologies (FET) and FET Japan, Inc. (FETJ), to purchase certain assets and to transfer certain technology from FET, a leader in FED (field emission displays) technology whose 39.8% of shareholding is owned by Sony Corporation. In the transaction, AUO will acquire certain assets that include patents, know-how, inventions, and relevant equipment related to FED technology and materials.

FED display is self light-emitting and has great contrast and low power consumption, with no motion blur and deeper color depth -- capable of 12bit gray level. With Sony and FET's efforts, FED technology and the possibility of its mass production have achieved a breakthrough. FED is intended to target high-end display applications.

AUO to start OLED production in 2011, says CEO

Chen said AUO is venturing into other technologies and fields, such as OLED and solar energy, as it has realized that capacity expansion and migration to higher-generation production for LCD panels are no longer the most important goals for the company.

AUO has recently acquired FED (field emission displays) technology from Sony's affiliate Field Emission Technologies (FET) and FET Japan (FETJ), and expects to start producing FED products in 2011-2012, Chen said.

[Phill1978]

will this tech feature in pc monitors at all ? not saying i want an iradiated face but poor light grey / black levels on lcd and motion respone are what make pc gaming worse now not to mention 60hz fixed (new 120hz screens combat this)

if so would this tech allow for a ultra thin bezel ?

[Nielo TM]

No and no, sorry

Looks like this tech is for pros

[sampo]

When will you be ready to demonstrate FED prototypes?

AUO: FET completed and demonstrated a 19" prototype in 2008. We hope to demonstrate our own FED prototype in Q4 2010.

What advantages does FED technology have, compared to LCD and OLED screens? Tell us about response time, viewing angles, contrast, brightness, price …

Because it's the only impulse-type display out of the three, FED is especially superior at producing images free of motion blur, which is an important feature appreciated by professional monitor users. To date, OLED, LCD, and PDP are known as hold-type displays liable to suffer ghosting. With special designs, LCD and OLED may attain impulse-like quality. However, the performance and cost are turn be compromised.

Note: documentation from AUO suggests that these FED displays will reach refresh rates of 240 Hz, so 3D won't be problem at all. In fact, it should be possible to produce even better results than we currently enjoy. As for contrast, current FED screens are already above 20 000:1, with blacks as dark as less than 0.01 cd/m². Greys are encoded using 10 bits, unlike the 6-8 bits used in today's LCD screens. Finally, one of FED's biggest advantages is that it will allow upscaling without adversely affecting the quality of the display and no dead pixels.

How big will FED screens be?

To start with, FED displays will be aimed at the professional market. Sizes ranging from 8" to 46" will be introduced in response to customer demand.

Would it be only for monitors? What about other products?

AUO has a range of display technologies to meet various customer needs. We will collect feedback from customers to produce the right solutions. At the moment, AUO views FED as a potential technology to challenge professional CRT and LCD monitors thanks to its superior image quality. We're not currently looking at mobile devices.

Better start saving now.

[Nielo TM]

Panasonic already concurred motion resolution and just a year or two away from offering even deeper blacks (2011/2012 models).

Sounds is fine for "FED"

I hate CCFL even Baclit-LED panels too!!

Looking new-tech panels as well!!

-SED is a mystery and hide on Canon-Tosh side
in the meantime the license of SED(by NANO Prop./USA)
in Canon hand "still"

-Lets see "FED" now

In past I'v read some of infos about Sony-Pio will handle
this FED panels on Pios factory!!

Bye++
