69.1: Image Quality Assessment of Ultra‐High Resolution Mobile Display Utilizing New RGBW Method

In the contemporary media environment, visual content takes many forms such as TV, monitor, mobile device, photographs, and printing. Digital contents are encoded in various color standards and output media has difference color capabilities. Thus, a Color Management System (CMS) is important to ensure consistent color reproduction capability. In this paper, we propose appropriate color optimization for OLED display using gamut mapping. Our technique can used to accurately, reproduce sRGB and Adobe RGB. OLED has wide color gamut compared to LCD's. OLED have ability of reproducing natural colors that LCD cannot covers.

“…We have developed a new RGBW method based on the "Extended HSV" color space model [2][3][4][5][6][7]. This method provides a simple way to determine the White output (W o ) and RGB data (R o , G o , B o ) and input data (R i , G i , B i ).…”

“…However, conventional RGBW technology has problems with image quality, such as color purity degradation caused by both the signal processing itself and the optical illusion called "Simultaneous Contrast" [1]. Recently, we have developed a new RGBW method to solve this problem utilizing an Extended HSV color space model [2][3][4][5][6][7]. We have also reported a new RGBW display that has good color reproducibility utilizing a color management system [6].…”

“…Color distortion is attributed to the reduction of the brightness of primary colors by 25% and the so-called "Simultaneous Contrast", while the loss of display details may be ascribed to the resolution reduction compared with RGB. [6][7] So it is important to employ the RGBW pixel format to significantly increase the power efficiency of the LCD displays without decreasing the chrominance of primary colors and display details. In fact, the image quality of the RGBW display depends strongly on effective RGB-to-RGBW mapping algorithms (RMA) consisting of RGB-to-RGBW conversion methods (RCM) and RGBW sub-pixel rendering methods (SPR).…”

P‐49: New RGBW Mapping Algorithm for High‐Quality‐Image LCDs

et al. 2017

The key issue preventing RGBW LCDs from wide application in the display market was probably the absence of a proper RGB-to-RGBW mapping algorithm with no color-distortion. In this paper, a new RGBW mapping algorithm was designed so that the hue and saturation remain unchanged from the original color. Perception experiment for new algorithm based on our intellectual energysaving technology (IEST) product indicated that it has superior performance upon conventional RGBW and almost indiscernible to common RGB.
