19‐1: A Novel Electrowetting‐based Display for Future Smart Window Application

Abstract

Smart window is an emerging application for display industry. It can control the sunlight penetration and display information. In this paper, we had made 6-inch color smart window prototype by electrowetting-based technique. The ink jet process is adopted to dose various colored oil into sub-pixel to achieve color device. Without color filter, the transmittance of the device can be improved. Further, to evaluate the practicability of using the smart window device in the night, we had added luminescence substances into the colored oils and designed the cladding structure to achieve a luminous smart window.

Large area and low power dielectrowetting optical shutter with local deterministic fluid film breakup

“…[1][2][3] Some applications, such as smart windows or switchable architectural/privacy glass, pose even greater challenges, including a need for very low cost, low haze, default to a clear state with power-failure and a desire for optical transparencies that are beyond the <50%, typical of existing commercial products. Current approaches for smart windows include [4][5][6][7][8][9][10][11][12][13] photoelectrochromics, photochromics, thermotropic, polymer-dispersed liquid crystal, thermochromics, suspended particle, electrochromics, counterion exchange, and electrowetting. For large area windows or architectural glass, unlike pixelated (matrix) displays, one aspect that is not highly constrained is the use of higher voltage or frequency as long as the power consumption is adequately low (high voltage/frequency inverters are low cost, e.g., compact fluorescent bulbs).…”

Study on the relationship between project management and organizational efficacy in nonprofit organizations

“…Thus, the two show certain degrees of differences [37][38][39][40][41]. Based on the definitions and views of scholars [37][38][39][40][41][42][43][44] regarding organizational effectiveness, this study defines NPO efficacy, as follows: NPO members of different levels and categories fulfill their duties, accomplish the organizational objectives, and make efforts for the plans set by the organization to result in the positive performance of organizational management and operation. NPO efficacy in this study refers to the following five items:…”

6.3: Distinguished Paper: A 9‐inch Flexible Color Electrophoretic Display with Projected Capacitive Touch Panel and Integrated Amorphous‐Silicon Gate Driver Circuits

“…In recent years, Ebook readers have become more popular, as well as more affordable, and most people are looking forward to getting the different reading experiences from it. Among the many media technologies, such as cholesteric liquid crystal (ChLC) [1], electrowetting display (EWD) [2] and electrophoretic display (EPD) [3], EPD has been considered the most ideal display for Ebook reader applications because of its outstanding properties in bistability, high reflective contrast ratio, low power consumption, wide viewing angle, and possibly also flexible display. Thus, intense efforts have been made to develop Ebook readers in order to fulfill a customer's requirements, needs or desires.…”
