Phillips develops new e-paper technology that is closer to printed paper
An article from Technology Review says that Phillips Research has developed a new method for creating color e-paper displays that will be three times brighter than the current color displays. The method is known as in-plane electrophoretics, and it uses colored particles rather than color filters which are used in E Ink. The display is brighter with colored particles because color filters require four subpixels for each full-color pixel which reduces the resolution and the brightness of the display. The technology is still very new and Sri Peruvemba, vice president of marketing at E-Ink, predicts that it will take at least three years for it to hit the market. When the technology is available, it will offer some distinct advantages over color filters because it relies on cheaper and simpler electronics and it is more suitable for creating flexible displays.
