Abstract

The recent color display market is being focused on displays with larger panel size and larger color gamut. More specifically, for widening the color gamut, multi-primary display (MPD), which is a display having more than the conventional three-channels, has been an important issue. However, developing MPD faces many difficulties such as sustaining display luminance against 3-color displays, embodying a simple H/W structure, and assigning new color signals based on input RGB signals. The purpose of this study is to propose a method to display color on a new pixel structure for flat-panel displays with six primary colors intended to expand the color gamut, and to discuss a color decomposition algorithm for this new structure to assign signals to 6-channel from an input RGB signal. Special interests of this study are made on minimizing the deterioration of color image quality compared with RGB-based display and maximizing the usage of the widened color gamut. The result of this study was implemented on a prototype 6-color LCD and verified generation of the color signals for 6-color without luminance degradation. The device is capable of reproducing colors like emerald cyan, which cannot be displayed on a conventional RGB display. In addition, hardware implementation on FPGA verified commercial viability of the algorithm.
