Until now, computer displays have been incapable of showing the true range of luminance observed in the real world. On a sunny day, objects illuminated by the sun can easily have luminance values which are more than 10 times brighter than conventional monitors are able to display.
That’s because traditional flat panel LCD computer displays modulate light coming from a constant and uniformly bright backlight, which usually consists of one or more fluorescent tubes behind the LCD glass.
But in Brightside Technology’s display, this backlight has been replaced by a controlled array of ultra-high brightness white or tri-colour light emitting diodes (LEDs) creating a display with an extreme dynamic range.
To demonstrate the technology, the company has recently launched a 37” display that provides peak luminance in excess of 3,000 candela/m2 and a contrast ratio in excess of 200,000:1. It is also claimed to be the first display capable of accurately displaying 16 bit per colour channel images.
Initial target applications include film, medical, geophysical and satellite imaging markets - vision critical applications where improved visualisation of complex data is essential for better analysis and decision making.
