次世代Displayの色再現性

It is said to recognize each color by a light receiving body in response to a color of R,G,B the human being. In late years the LCD adds a new color and investigates the delicate color reproduction nature.

On the other hand, the general TFT tries for improvement of a picture by articulate 64 of the harmony of each color by spreading with 4096 gradation. The chart below shows a characteristic of the sight.Existing Display expresses a color by the combination of three primary colors using the curve of this characteristic.

Display expresses object color 3 with the arbitrary spectral distribution characteristic by the extreme combination of the primary color. It is expressed a spectrum curve by a small harmony approximation with three points in a human sight wavelength range. That there is considerable individual difference in a human sight characteristic is reported.

Here is a limit of existing R,G,B expression Display System. In other words the color expression by three primary colors is not technology to express a color to all people equally. The color reproduction of Display-related final aim is to reproduce the spectral distribution of the pixel. Only spectrum DISPLAY has absolute color reproduction characteristics

Spectrum Display is unrealizable in Color Filter of R,G,B or the Display technology with a fluorescent substance. Only Color Filter less Display technology to use backlight as a source of light of the color development is the technology that can realize spectrum DISPLAY.

Spectrum DISPLAY technology is original technology of the photon energy Institute.
