ABSTRACT

Market for displays capable of rendering colors to match appearance of

naturally occurring surface or designed colors in such fields as industrial design,

digital archiving, network-based remote medical care and electronic commerce is

gaining in popularity. Based on this need there has been intensifying efforts to come

up with a solution in achieving this capability. One such effort has resulted in

development of natural vision technology, a technology for rendering color images

identical in appearance to real-world objects. It evolved out of an R&D project

(October 1999 to March 2006) led by the National Institute of Information and

Communications Technology (NICT) Japan, an independent administrative agency of

the Japanese government. Today Sharp made an announcement on development of

five-primary-color display capable of truly reproducing the real surface colors that

humans are capable of perceiving. The newly developed display comprises of “Multi-

Primary-Color Technology” featuring special image processing circuitry plus a

display panel whose pixel structure is based on five-color filters that add the colors C

(cyan) and Y (yellow) to the three colors of R (red), G (green), and B (blue). This

combination helps with further expansion of color gamut which can be rendered

within the color spectrum that humans are capable of discerning with the unaided eye

plus it will provide a capability in the display in producing more than 99% of real

surface colors. With the newly developed display nearly all real surface colors can be

truly rendered, such colors as the color of the sea (emerald blue), brass instruments

(golden yellow), and roses (crimson red). Furthermore, the new display provides

greater energy saving option due to its ability for efficient use of light energy

produced by the backlight. Sharp does not have any immediate plan for

commercialization of the new display, as the company is planning to further improve

the basic performance of this display in anticipation for its practical application.
