Display Technology: an Ecosystems’ tapestry? Part 1.

Monday, March 16th, 2009 by Roberto Saracco

Display technology has progressed significantly by leaps and bounds in terms of performances perceived by the user although we are seeing a continuous evolution in terms of production processes. It is this latter evolution that leads to decreasing prices and growing adoption.

LCD technology is moving from the resolution of 2 Mpixels (6 million dots) of HDTV to the 8 Mpixels (24 million dots) of the cinema resolution (4k) and by the end of the next decade we will see the 32 Mpixel (8k, 96 million dots). The problem with LCD is that the size of the single dot cannot be squeezed without reducing its brightness, therefore limiting in practice the number of dots that can be crammed in a given surface. Plasma screens are on a similar evolution path and are similarly constrained (a plasma “dot” is even larger than an LCD “dot”, that’s why we don’t find plasma in small screens). Bettering in the production processes makes it possible to have larger and larger screens, although their size is limited in practice by the space required that is rapidly exceeding the one available in the average living room.

New technologies, like OLED (Organic LED) and NED (Nano Emissive Display) significantly reduce the dot size without reducing the brightness (by a factor of 5-10 in the case of OLED and by a factor of 30-50 in the case of NED). This will allow ultra high definition on screens having dimension in the range of 40”-50”.

Ultra High Resolution (over 8 Mpixel) is interesting since it overcomes the resolution power of our eye. By looking at a screen exceeding our eyes resolution we can’t tell it is a screen anymore. The image looks like the real thing. If the screen size and our distance from the screen is such that we can’t get the whole image without our eyes scanning the surface our brain is tricked into believing that we are part of the scene. This gives us a very strong sense of immersion.

Add to this a touch screen and software that codes the various elements of the image in separate objects and we can manipulate the image, moving pieces around thus seamlessly interacting with the scene.

Having this kind of display stimulates interactivity. The separation of the image into separate objects allows different companies to take hold of one specific object and wrap it with information and services.

A movie becomes a seed for an ecosystem composed of the objects displayed in the movie, of those enterprises enriching the objects and of the people interacting with them.
