Display Technology, Standards, and Storage/Distribution
« on: May 25, 2015, 06:16:01 PM »
Have any of you heard of ITU-R Recommendation BT.2020, AKA Rec 2020?
It is a new standard for displaying 4k content, it includes 4k and 8k resolutions (and no lower resolutions) and has its own color space (which has very bright and pure primaries) with rougly double the gamut of the current system (Rec 709)

Have any of you heard of Organic Light Emitting Diodes, AKA OLED screens?
They are a bit expensive and fragile to make currently but soon will offer eco-friendly (for manufacturing and for energy usage) screens that could be mostly clear and even roll up.

Have any of you heard of Quantum Dot Display?
They are tiny semiconductor crystals (nano-crystals) that act like atoms in some ways. They can be fine tuned to emit a narrow range of light when excited by photons or electrons. They can be combined with a blue LED backlight to make LCD screens capable of displaying Rec 2020 pictures.

Did you know that Blu-Ray Discs will soon (by the end of the year) support Rec 2020 format films (high resolution, many colors, at any speed, even 60Hz), which for those that want the best picture quality on a brand new screen, will be the perfect medium for such movies. However, such disks will not be of much use for old screens (which means Netflix is more attractive for watching on old laptops or on computers with old (more than 2 years) monitors)

Some movie company (or maybe several) sell hard drives with several of their 4k movies on them.

What do you think of this bright, colorful, high resolution future for display technology?

The shaping thingie will, when prices drop, have a lot of use in comercial displays. (Storefronts, wrapped around coloumns and anywhere else there will be an available surface. Combined with proximity sensors and a link to an advertising company that you have fed with more of your life and wants than you are aware of yourself- you will be hailed with special offers tailored just for you).
As for the resolution thingie: More dots per square millimeter has little effect- what this will do is allow you to sit even closer to thelarger screen without discerning pixels. Something I've often wished for in both digital sensors (cameras etc) and displays is a larger intensity range and more bits in the band (8 gives a bit too much of a staircase). In ordinary equipment you still can't beat the information in a pancromatic film properly exposed and developed. The standards need to incorporate more bits per band and have a broader range from zero to saturation- this new tech will allow it, at the price of (very much) larger data sets.
