Is the black of our monitors and TV’s really black?
‘Dolby’ became synonymous with a high quality sounds and drove innovation in the high end of the audio processing equipment.
Yet, back in the 60s, video was the first love of Ray Dolby.
However the level of technology available there could do little in the video realm.
Your typical technology end user is not much interested in how something works and cares much more of the quality of experience.
The end result of the latest proposal of Dolby is that the black color shown on a monitor or a TV will be really black, and not a dark gray.
In the majority of the present day monitors and TV’s based on LCD technology, the source of light is a single CFL (cathode fluorescent lamp).
Dolby proposes to replace this single source of light with a matrix of hundreds of thousands of LEDs (light emitting diodes) - which can be individually controlled.
Major LCD manufacturers are interested in incorporating this proposal in the new models of equipment, which as an added benefit may make new technologies thinner.
