This has absolutely nothing to do with the technology itself. It has EVERYTHING to do with the stable, reliable, and cost effective MANUFACTURING of these devices, which had always been relegated to research projects coming out of the R&D department of Sony, Samsung, panasonic, and your local graduate research university.
people keep commenting that the technology has been around for years. Please... the Technology has been around for DECADES, the Nobel Prize in chemistry was given for the technology that underlies these devices in 2000, referring to work that was done in the late 1970s.
The limiting factor has ALWAYS BEEN: Cost. These devices are AMOLEDs. ORGANIC light emitting diodes.
These organic polymers are made using incredibly expensive materials that must be synthesized using expensive reagents (like platinum, rhodium, and rhenium catalysts) and techniques (microwave synthesis)...
That is just to get the chemicals. The actual manufacturing of the devices has ALWAYS been the subject of a Ph. D. research project, taking years to master...
Sony actually sold some, comparatively small, OLED screens for a while... They were something like 10-15" and cost $2500.
they were just proof-of-concept devices, made using painstaking and expensive manufacturing processes.
If you were even remotely intelligent you would realize that the POINT of samsung's demos is this:
they can now manufacture these AMOLEDs with high yield and regularity, thus allowing their use in currently available mobile phones.
the Flexible AMOLEDs are also manufactured in a high enough yield and with a high enough regularity to allow their demonstration with PERFECT examples at CES and equivalent.
look up the pics of previous examples of this technology. Google image results displays the same 5 pictures on about 100 different websites.
You will notice that, conspicously, one of the most eye-catching images, of a flexible 1"x1" (roughly) display HAS A BUNCH OF DEAD PIXELS!!!!
Samsung is proving their strengths with PROPRIETARY MANUFACTURING ADVANCEMENTS... not the technology itself
