Interfacing a LCD screen with a FPGA

[diracshore]

Looking at recent ipad 3 rumors it would appear mass production of 2048x1536, 9.7 inch screens has begun in China and the price will be around $120.

It would be nice to try something like this with these new parts, perhaps using say 4 at a time. With linux combining 4 screens is quite trivial.

Just putting it out there. Would be interested in thoughts and opinions.

2048x1536 ? No . That's rubbish . How do you squeeze that much when all of the common TV screens can't even do that ?

2048x1536 15" has been around for some time already, look up the 92P6684. I don't find 9.7" at that resolution today to be much more than that.

The refresh rate with using 4 of them at a time over a single link can't be very high. Maybe 4 video cards would be better suited to that.

The point is , how unreadable do you want anything to be ?
The ppi is way too high .
15" is okay , but 10" ... you know , technology can't improve so far .
the QoP is also important .

How can ppi be too high? Why would high ppi be unreadable? There's no requirement for characters to be 8 by 5 pixels. Just increase the resolution of the fonts and you get nicer, sharper text. Resolution is 256 ppi, lower than the modern iPhone displays, for example, and I don't see anyone complaining that its display is too sharp. Do you also believe that printing photographs at 400 ppi is pointless? Why should displays be any lower? Is there a requirement to always keep them at arms length?

Sure, there will be diminishing returns at some point, but if the technology is available and the costs are not prohibitive, why not?

The resolution of the next iPad is still going to effectively be 1024x768, except instead of 1x1 actual pixel per "pixel", there's 2x2 pixels, making a sharper, but not smaller, image.

I think you might be surprised how easy tiny text is to read. If the resolution is capable, then you can feed it whatever you like, even if Apple just want to sharpen image uses. Using linux it is often the case I have never ending realtime log readouts I have to refer to. It would be nice to use a screen like this. Plus you know they will be IPS.

The resolution of my motorola droid is 235 ppi, and I find that a distinct improvement over most device displays.
I didn't find the measurements exactly but I think this display should be like 250-260 ppi.
I find the higher ppi very nice, whether just for playing angry birds or esp. using dynamic zoom on a large doc or web page.
That res. on a 9-10" screen, with enough hardware to run it smoothly... that plain makes me drool.
