A lot of people are wanting to know why you can't have bezel less LCD panels.
Simply put, the pixel grid doesn't extend to the physical edge of the panel. Instead there is the matrix connection which results in a border.

I stripped this panel down to illustrate. I'm no photographer and the panel is hard to capture for many reasons - so the pictures are the best I could do.

Note that I used a laptop and VGA input so the screen resolutions isn't native. Shows up the poor scaling.

Thanks, helpful. So with a custom frame, we can have 3 monitors eyefinity setup with .9 cm border.

Yes, but a border all the same. A lot of people wanted to know if a true bezelless monitor setup was possible. They wanted to know what was under the metal bit. Now they can see.

I'm going to try twin projectors instead. Eyefinity is great tech but I the bezel thing and fish-eye issues put me off.

Wonder how hard it would be to do an LCD with a plasma backlight?

What do you mean? Plasmas work by exciting gasses to emit ultraviolet light - which in turn lights up phosphor pixels. Its essentially the exact same way a CCFL backlight works.

Careful with the flex stuff connected to the glass, the connections are extremely fragile.

st,
plasma seems to work by embedding gas between two glass layers and electrifying it, ultraviolet light emitted from this composure is exciting phosphors built within each pixel on the screen.
LCD works with gas encapsulated within a glass chamber which has the same effect as neon light (and so works same as plasma idea just in a different architecture), the light is being emitted toward the screen which has RGB filters in it.

you cannot put "plasma light" into an LCD, cause u simply would have to make an lcd out of it,
they simply work on the same idea yet implemented differently.

You can happily pick up the panel via the ribbon cables. These are actually very strong. All the manhandling done during its naked photoshoot didn't hurt it. I reassembled it and use it as a secondary monitor.

When I acquire an overhead projector I will strip it back down and have a play.


Infrared light damages an LCD. When you use the panels as overhead projectors you need to install heat and IR filters if you want the panel to last.

There is/was an university project which made seamless (true bezeless) LCDs - but I can't find it now. It was MIT or similar calibre institute.
The Inifinte Plasma is not seamless (5mm).




Overall I dislike LCD technolgy it truely feels like jumping back to 16bit colour days. The banding is terrible. I did a lot of side by side image testing with a 21" CRT vs 22" LCD. DVD's and HD images alike. At first, I honestly thought the LCD was faulty.

The bonding is strong, but the contacts are not.

did u check them vs IPS's ?

the LG ^^ up there is an LCD, not 100% bezeless yet much better than the current casual display is :yepp:.

it just isn't clear whether they got the bezel -inside- as the LG mark is still on the screen.

Yep. LED backlight wouldn't be any worse, in fact, probably even better. :)

actually, LED backlighting should indeed be better as the LED matrix is much more controllable and dense then CCFL's are.
the actual deficit between LED/LCD and plasma's is the fact plasma uses phosphors to control color levels while LCD's/LED's uses dyed filters,
phosphors simply seems to give better hues then the other.
the actual process that enables plasma to excite the phosphor is unattainable using LCD's/LED's lighting,
that is the basic quality difference.
