SED HDTV the future tv set every one must have ?

Question

please tell me more about SED TV i.e. surface conduction eletron -emitter display. As l know this is the latest good tv to replaced the LCD and Plasma !

Answer 1

well its like this,

In LCD you have Crystals and in Plasma you have Excited Gases.

In LCD, the Processing Unit (PU) converts the analogue picture and processes it in form of 0's and 1's (on and off) which brings out a 'Pixel' characteristc, to form an image.

something like this:
...
‪‌ ‪‌.
‪‌ ‪‌.
....
the dots are 'on' or 1's and the blank spaces are 'off' or 0's

In Plasma, its almost the same but there's a li'l difference. The Gases present in the screen are excited and they emit desired colours on the screen. (All this happens at minute scale) and the image is formed as above.

when this is the condition in Plasma and LCD, The Pixels are out to conquer the technology which was left out (standard CRT) [Old Fashioned Television]

In CRT, excited state of elements of gases are made to strike a phosporus screen, which emits image at minute scale, at a time, thousands of strikes takes place to form 1 single frame of image.

SEDTV is Pixelized CRT!

SEDTV contains CRTs but not 1, not 2, but more than a thousand (depends on model that you opt for)
Each CRT (Tube) is made as a Pixel and these tubes are arragned in fashion of a LCD and the strikings take place in respective tubes to form an image.

This requires a lot of Image Processing just similar to that of a LCD.

and SEDHD contains atleast 780pixels or 1028 pixels (that means the number of CRTubes inside them). Imagine, a fast paced video... is being played on a SEDHDtv what would you see ? A series of Blurry Pictures (A lot less Blurry than LCD)

I advise you to stay away from that and wait for OLED ones. (they are cheap and power saving with quality matching to that of an LCD) Or if you are so patient enough, wait for an OLEDHDTV :p

Happy Shopping!

Answer 2

SED TVs use a method similar to CRT televisions to project the image. However, they essentially put a miniature cathode ray tube behind each pixel. Additionally, current test models boast a 1 ms response time and about a 50,000:1 contrast ratio. Unfortunately, there still don't appear to be any fully commercialized models.

Answer 3

I think LASER TV might be next

Also Philips has a 42 inch 3D display panel which is very convincing.Have a look.

The launch of S.E.D. TV has been put back.

Answer 4

If you remember The Honeymooners, Ralph was waiting for 3D television to buy his first TV!
Well, he would be still waiting after 40 years or so....

Answer 5

you additionally could make it look slightly greater powerful yet standard i think of that's you who do no longer purely like the look of the video games anymore considering you have seen something greater powerful. I used to think of a few PS2 video games like God of conflict 2 regarded surprising yet upon getting a PS3 and playing PS3 video games I do exactly no longer think of PS2 video games look all that large. comparable way i do no longer think of DVD movies look very reliable after having watched a collection of Blu-Ray movies.
