im confused. i thought LED/OLED was the way the backlight is produced. and IPS/TFT etc is the way the picture is made? how can you compare IPS->OLED if i am correct?

LED and OLED displays are different.

You are correct in that where LED is used it refers to the backlighting. For example, an LCD display (IPS, TN,, S-PVA etc) may have either an LED backlight or a CCFL backlight.

However OLED is a different beast entirely. It functions as both the display and backlight (It doesn't need a seperate backlight). Organic LED's aren't actually seperate LED's; it's actually a film made up of thousands of them. They produce their own light and color.
 
Does anyone know if the iPad will up-convert SD content, or is it just going to stretch it across the display?

A lot of my 640x352, 640x480 and 720x480 content looks really good upconverted on the Apple TV, but I'm not sure what it will look like on this device.

*While 1024x768 being HD has been debated a lot around the web, as others mentioned, on a device of this size, it may as well be HD. You'll notice the crispness and clarity. The extra horizontal space isn't going to be missed, most likely.

thanks for the explanation!

it seems pretty silly then to compare IPS to OLED then isnt it? you would have to compare IPS + backlight technique used to OLED.

is it true that inkjet printers are capable of producing OLEDs? (with modifications of course) - i thought i read that somewhere.

so it is true that OLED generally provides a better picture then IPS/LED etc?

OLED is the future but it still has a few "in development" problems. Not quite bright enough and the color will fade over time. Also since it is still a somewhat new technology it's very expensive. However it has some big advantages. Since there is no backlight needed it can be made many times thinner than LCD/backlight. In a few years we (likely) could have a paper thin roll up iPad. OLED also uses less energy and can be "printed" (but not on your inkjet) into almost any size and resolution. In a decade (or so) you should be able to buy a 150" 4K screen in a roll. Then take it home un roll and hang it on the wall to hane an instant HT.

ok so the inkjet thing wasnt accurate, but it is effectively "printed" onto a surface and i presume an electric charge then runs through it?

OLED definitely does look like the way of the future in terms of projection - still quite expensive but it does look pretty good. organic also indicates that it is somewhat renewable and very efficient, i like!

a decade to get 4K 150"? hmm... i was hoping for a tad more - more something like super high res! (4x that of 4K).
 
Again, this solution takes up much more disk space.

It boils down to each individual's preference. :)

On the computer it does but you mentioned that HD shows can get synced to the iPhone/Touch, taking up more space when only SD shows can get synced. Of course they will take up more space on the iPad.

Oops. My bad.

Got confused with an NCIS episode. I had contacted Apple for a re-download since the copy that I got was corrupted. They gave me the HD version, so I contacted them for the SD version and ended up with two copies of both. So what I thought was the HD version was actually two SD versions if that makes sense.

So I will go eat my crow while it's warm. :)

I wonder what the iPad will do in cases like this? Will the iPad sync the HD version (if you want it) or just the SD version?
 
Thanks for that. So if the iPad scales the HD video to standard definition than it is not worth paying the extra.

Actually this is not correct. The iPad wouldn't scale down a video to standard definition.

Take for example 720p (1280x720), as the iPad's screen resolution in landscape is 1024x768, the iPad would only scale down the video by a factor of 1:1.25. Thus the resolution would be 1024x576. Standard definition, from the iTunes store is 640xXXX depending on widescreen or 4:3.

The down scaled 720p would look more crisp than a SD upscaled would look. This would have a scaling factor of 1:1.6 and wouldn't look anywhere near as good

Two questions: One, Can I purchase HD (720) movies/ TV shows from the iPad iTunes store with the iPad and Two, can I connect the iPad to my HD TV like I do my Mini with a HDMI adaptor?

It depends on your TV but you MAY be able to hook it up to your TV.

You'll need a VGA to HDMI adapter and a television that accepts a separate audio input through a different channel then HDMI. Alternatively, many TV's have VGA connectors with matching audio inputs.

And yes, you'll be able to purchase a 720p movie but it will neither output to the TV in 720p nor will it be shown at full resolution on the iPad (either letterboxed or with about 200 pixels cut off the sides in full screen mode).

Regardless, it will probably look great on the iPad.

Okay, then LED IPS display is better than OLED currently when viewed in sunlight.

Thanks for the reply.
 
that might seem like a comparison worth checking ;)

is OLED better in inside conditions?

Yes, OLED is better in light controlled settings. One thing I still don't understand is how Apple managed to get any kind of battery life with an IPS display (much less 10 hours!)

Most people think it is an LG display, which means it is likely using E-IPS.
Believe it or not, the LCD is cutting edge technology directly from LG Electronics called Enhanced IPS. In-Plane Switching is a Liquid Crystal Display technology that aligns the cells horizontally giving a wider, cleaner range of vision for the user. In order to do this, each pixel must have two transistors on either side of the cell unlike the single transistor model of the typical TFT (Thin-Film Transistor) display. Before the Enhanced IPS display from LG, two transistors actually reduced the amount of visible light that traveled through the cells. This resulted in a need for more expensive and more powerful BLUs (Backlighting Units). The more powerful the backlight, the more battery drain. That was a huge concern to mobile companies because their devices that need all of the extra juice they can get. LG took IPS technology and “enhanced” the cell structure to allow more light through each cell and regain the use of standard BLUs. This means that we can all benefit from IPS technology in our mobile devices without any decrease in battery life. Thank you, LG.

This coupled with LED backlighting and the new A4 chip have made their battery life of 10 hours attainable.
 
1024 x 768... is technically HD, but not a good ratio... makes movies/TV shows look odd.

would be very odd wouldnt it! it would be 1024xwhatever the 16:9 ratio is of the width lol. :confused:

oh 1024x576 according to G4R2 a few posts back. it would do it all itself though.

ps thanks gibbz!
 
righto OLED is good then :D however would have pushed the prices way high, double what it is now maybe?

Try quadruple. I would say AT LEAST $2,000. But it's hard to know considering no one has ever mass produced a 10" OLED before.

The only company who has ever released an OLED TV was Sony. It was 11", $2,500, and only had a resolution of 960x540.

Take into account OLED screens suck in sunlight, where many iPad users may be under.

oh wow. thats ridiculous!! IPS was the best decision then it seems - for now :D
