Thick-film dialectric electroluminescent technology
Thick-film dielectric electroluminescent (TDEL) technology is a phosphor-based flat panel display technology developed by Canadian company iFire Technology Corp. TDEL is based on inorganic electroluminescent (IEL) technology and has a novel structure that combines both thick- and thin-film processes. An IEL device generates light by applying an alternating electrical field to inorganic light-emitting phosphors. Traditional IEL displays are bright, very fast in video response time and highly tolerant of environmental extremes. However, the lack of full-color capability and large-size scalability has limited their application for the mainstream consumer television market. iFire has addressed these limitations by replacing the thin-film dielectric of traditional IEL technology with its patented thick-film, high-K dielectric material and structure. The result is a unique flat panel display technology that provides iFire™ displays with high performance and low cost potential.
Additional recommended knowledge
The TDEL structure is made on a glass or other inexpensive substrate consisting of a thick-film dielectric layer and a thin-film phosphor layer squished between two sets of electrodes to make a matrix of pixels. It seems complex, but basically it works when phosphors emit light in the presence of an electric field. And because TDEL uses solid-state phosphors instead of liquids (as with LCDs), gases (as with PDP) or vacuum (as with the CRT), it is probably the most sturdy new technology, less prone to shock and breakage during shipping.
Color By Blue
In 2003, iFire announced the development of a process, known as Color By Blue™ (CBB), which further simplified the already simple manufacturing process for TDEL. The simpler Color by Blue manufacturing process was made possible by performance improvements to iFire’s blue inorganic phosphor. The Color By Blue process achieves luminance and color superior to the previous triple pattern process, as well as increased contrast, better grayscale rendition and exceptional color uniformity across the panel.
Characteristics and market place
Besides its durability, TDEL's claim to fame is its low cost of production. According to the makers, TDEL display would have half the capital and manufacturing costs of a similar LCD or PDP.
