74‐2: Development of a Novel Reflective Display System with Multi‐primary Color for Digital Signage

Abstract

We have developed four primary‐color reflective LCD and have improved yellow and red color saturation. The color gamut area of the developed LCD meets to the standard for printing (SNAP) which is defined for reproduction quality in newsprint production. The developed LCD has also a wide color gamut, wide operating‐temperature range and high‐quality moving images. It is suitable to realize future digital signage for outdoors.

74‐3: Development of New Error‐Diffusion Dithering Method for Reflective Memory‐In‐Pixel (MIP) LCD

“…We applied "Segmented Error Diffusion II" to a prototype 31.61inch FHD four primary-color reflective MIP LCD [5]. Table 2 shows the specifications of the prototype reflective LCD with "Segmented Error Diffusion II" method.…”

P‐64: Research for Large Size Reflective LCDs

“…Reflective LCDs, which have no backlight units, are promising candidates for mobile devices, digital signage, and so on. Because they are thinner, lighter, and have advantages such as low power consumption and outdoor visibility [1], [2]. Lightdiffusing film with beneficial effects on polarizationmaintaining and backscattering is necessary for reflective LCDs to improve reflectivity [3], [4].…”
