Sony Begins OLED Mass Production 193
Dodger73 writes "According to their press release at sony.net, Sony beings mass production of full color OLED displays at 3.8" size for their Clie PEG-VZ90 'Personal Entertainment Handheld.' The press release claims, that their 'Super Top Emission' technology reaches 150cd/m^2; at the familiar 1000:1 contrast ratio.
Not quite the 19" display I'd like for my computer at home, but definitely a step in the right direction."

Even after all these years, CRT is still the standard. Amazing...

price (you still pay a lot less for a crt)
resolution (you can use any resolution on a crt, on lcd's you are limited to the built in resolution, important especially for newer games if you dont want to buy every half year a new pc)

Must be 5 years ago now for a project I was working on way back then, I got hold of a 12.1 inch 800 x 600 native Sharp industrial grade TFT (for those of you not in the know indusrial grade are the pick of the yield) which the had the standard sharp backlight, which was about 300 cd/m2 even way back then, removed and replaced with one from an american company called Landmark Technology which meant it was 1500 candela and true daylight readable even in direct sunlight... the screen was driven by an expensive (I forget the make for the moment) graphics engine which took the input RGB and converted it to the TFT native electronics signal format.
The image quality was absolutely astonishing, even blew away things like my current 21 inch sony 520, white WAS absolutely white, the most minute details such as the - - - - - - effects you get around selected dialogue buttons in windows were absolutely pin sharp, and when showing images such as some of the nature type pictures included in xp as default desktop backgrounds the effect can only be described as feeling like you were looking at a high quality photographic transparency backlit by a professional grade light-box.
The horizontal and vertical viewing angles were also pretty dramatic, with a very wide range over which brightness and contrast didn't appear to vary, response was also more than enough for multimedia playback.
So that was 5 years ago.
I haven't seen anything since that was actually better quality, except today I could get an 18 inch 1600 x 1200 panel, so these "new" ideas are cool and all, but I think their unique selling points must be anything other than true image quality, it must be something like very low power consumption, very much more robust, or perhaps extended operational temperature range.
Until one of those uses applies to me I'm quite happy to use the tft built into my dell laptop, but for desktop work it has to be CRT, for everything else such as the digital camera then the tft screens in built are no more use than thumbnail browaing in MHO.

That's actually better response than a standard CRT!!!
(Math behind that assumption: 75Hz monitor has a 0.013s, ie 13ms response time - and I'm going easy, the worst case scenario is 26ms, in case the change request happens just after the beam has scanned a particular pixel)
Leave it to sony though, to somehow embed their proprietary video codec into this screen and not allow you to use DivX (like they are doing with MDs... MDs IMHO were the coolest technology to be available forever, yet they never picked up because of their stupid reluctancy to allow for mp3s).

Amazing, why? What's so bad about them?
It's a fundamentally simple design, which has had lots of room for improvement. -Like the internal combustion engine.
And like the combustion engine, that means there's a high barrier to get rid of them.
So, while they are going to be replaced eventually.. it's hardly strange that they haven't been yet.

Trinitrons, though they have square/rectangular pixels, don't have perfect geometry because they lack subpixel-addressability. That's why cleartype only works on LCD screens. Additionally, the high end of LCD (ibm's 200 dpi screens) is much, much sharper than the high end of CRT. What distorts people's opinion about the relative sharpness of LCD and CRT is that CRT's often can be driven at higher resolutions than their dot pitch supports, which just makes things fuzzier (think: showing a 640*480 image on a regular TV, it's usable, but it's fuzzy). With LCD's you're pretty much stuck at their native resolution.
