Thick-film dielectric electroluminescent (TDEL) technology is a
phosphor-based
flat panel
A flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment.
Flat-panel displays are thin, lightweight, provide better l ...

electroluminescent
Electroluminescence (EL) is an optical and electrical phenomenon, in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black body light emission resulting from ...
(IEL) technology that combines both thick- and thin-film processes.
Technology
The TDEL structure is made on a glass, or other substrates, 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 were phosphors emit light in the presence of an electric field.
Color By Blue
Color By Blue (CBB) was developed in 2003. 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.
Color By Blue is based on the physics of
photoluminescence. High luminance inorganic blue phosphor is used in combination with special color conversion materials, which absorb the blue light and re-emit red or green light, to generate the other colors. This fluorescence is possible because the photons in blue light operate at higher frequencies than other light.
