36.4: Invited Paper: Large‐screen Flat Panel Displays based on Thick‐Dielectric Electroluminescent (TDEL) Technology

Abstract

Based on its proprietary thick‐dielectric electroluminescent (TDEL) display technology, iFire, together with joint development partners Sanyo and Dai Nippon Printing (DNP), has successfully developed 17‐inch full‐color prototypes with video quality comparable to CRT displays and a luminance of 300 cd/m2. The company's development of the Color‐By‐Blue (CBB) technique has further simplified the already simple manufacturing process of TDEL displays, and also accelerated iFire's development of the world's first full‐color 34‐inch inorganic electroluminescent HDTV screen. Based on detailed cost model analysis, iFire believes that the TDEL technology can be used to achieve high performance and low cost HDTV displays, and is initially targeting the 30″ – 40″ market segment, with commercial production planned for the 2006 timeframe.

AC powder electroluminescent displays

“…[10][11][12] Matrix-addressed ACTFEL displays have been discussed previously 13 and they are produced commercially by, for example, Planar. 14 Furthermore, it should be mentioned that iFire Technology, Inc., developed 34-in.-HDTV prototype demonstrators based on ACTFEL technology and its proprietary thick dielectric, 15 but it was unable to penetrate the market due to cost and performance considerations. No further atten-tion will be paid to ACTFEL displays in this review, which will henceforth concentrate solely on the ACPEL technology.…”

“…44296.16340 Легированный редкоземельными элементами (РЗЭ) тиогаллат каль-ция (CaGa 2 S 4 ) является перспективным материалом в оптоэлектронике и фотонике [1]. Максимальная энергия фононов и хорошие оптические свойства позволяют получать высокоэффективные люминофоры, а элек-тропроводность бывает пригодна для создания электролюминесцентных дисплеев [2][3][4] [5][6][7][8][9][10]. CaGa 2 S 4 с примесью эрбия дает фотолюминесцен-цию на длине волны 1554 nm, что подходит для применения его в телекоммуникации [11].…”

“…However, the process used to make the displays required 3 phosphor depositions and a variety of patterning steps, and with 3 different emitters, matching threshold voltages and achieving acceptable colour uniformity across all grayscales was challenging. In early 2003, iFire started development work on a new display architecture, which came to be called the Colour By Blue, or CBB, structure 8 .…”
