P‐69: Beyond RGB‐Primaries: Chromaticity Measurement Issues for Multi‐Primary Displays

Abstract

The current standards of color gamut measurement regarding RGB-primary displays are not applicable to multi-primary color (MPC) display systems. We show two case studies that measurement performed by simply extending the use of today's RGB-based standards is not able to provide accurate evaluation of the color gamut of MPC displays. The color gamut of MPC displays depends on signal processing algorithm; therefore, for measuring the color gamut of MPC displays, we propose to use not only the input signals of the maximum values for respective colors but also medium-level signals which are able to measure the chromaticity of respective primary color points on MPC display.

“…On the other hand, both progress of digital signal processing and development of liquid crystal technology such as UV 2 A mentioned above lead the performance of display beyond the broadcasting performance. Multi-primary color [5][6][7] is most promising technology to bring about display revolution which can defy common sense of display field.…”
