    Solid state luminescent devices for applications ranging from lamps to displays have proliferated since then, particularly owing to the develop­ ment of semiconductors and phosphors. Our lighting products are now mostly phosphor based and this 'cold light' is replacing an . This article will review the electrical and optical properties of thin film electroluminescent (EL) displays. A simple electrical model for thin film electroluminescent (TFEL) device operation will be presented and used to describe the luminance and power consumption of TFEL devices. The basic material characteristics that are desirable for EL phosphors will be described.

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.

[Esther M Conwell; M Stolka; M Robert Miller; IS & T--the Society for Imaging Science and Technology.; Society of Photo-optical Instrumentation Engineers.; SPIE Digital Library.;]. In general, an electroluminescent structure is composed of the four following layers, as observed in Fig.

two organic or inorganic electroluminescent materials, one of them able to emit electrons and the other able to emit electron holes, and two electroluminescent material can be organic or inorganic [3].At least one of the electrodes has to be transparent.

Electroluminescent Displays (ELDs) are a type of Flat panel display created by sandwiching a layer of electroluminescent material such as GaAs between two layers of conductors.

When current flows, the layer of material emits radiation in the form of visible light. Electroluminescence (EL) is an optical and electrical phenomenon where a material emits light in response to an electric current.

Luminescent Materials and Applications describes a wide range of materials and applications that are of current interest including organic light emitting materials and devices, inorganic light emitting diode materials and devices, down-conversion materials, nanomaterials, and powder and thin-film electroluminescent phosphor materials and devices.5/5(1).

Electroluminescence is the result of radiative recombination of electrons & holes in a material, usually a excited electrons release their energy as photons - light.

Prior to recombination, electrons and holes may be separated either by doping the material to form a p-n junction (in semiconductor electroluminescent devices such as light-emitting diodes) or through excitation.

Fig. shows the normalized EL spectra of the devices with doping concentrations of 5 wt% FIrPic in CBP (device 1), wt% Ir-BTPA in CBP (device 2), 5 wt% FIrPic and wt% Ir-BTPA in CBP (device 3), and 5 wt% FIrPic and wt% Ir-BTPA in CBP (device 4) at 11 V.

The EL spectra of all these devices display three emission peaks at, and nm) (devices 3 and 4), which create the. In this paper we review several developments that may lead to new EL devices: excitation by tunneling hot carriers, recombination of electron-hole pairs injected by pn junctions into wide bandgap materials, and the use of quantum wells to increase brightness and efficiency and to adjust the color by mechanical design rather than by chemical.

One dimensional (1D) light-emitting fibres emerge as a top candidate for flexible and stretchable displays, enabling the miniaturization of device architectures and integration of different optoelectronic materials and components for new applications in textile- and human body-mounted, biomedical and bio-ins.

Electroluminescent devices with double organic layers were fabricated using polymeric materials as the hole transport layer and tris(8-quinolinolato)aluminum(III) complex (Alq).

In a collaboration with Professor James Sturm (Electrical Engineering) and Professor Mark Thompson (Chemistry, USC), we developed a range of electroluminescent (EL) polymer materials for flat panel displays. Such emissive display technology has the potential to be ten times as efficient as liquid-crystal displays, and could revolutionize the world of portable electronic.

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 cd/m company's development of the Color‐By‐Blue (CBB) technique has further.

Organic light emitting diodes (OLEDs) are electronic devices made by placing a thin film of an electroluminescent organic material between two conductors of different work functions. When an electrical voltage is applied, electrons and holes are injected into the electroluminescent material.

When these recombine, light is emitted. Book Search tips Selecting this option will search all publications across the in Organic Electroluminescent Materials and Devices, edited by S.

Flat-panel displays are electronic viewing technologies used to enable people to see content (still images, moving images, text, or other visual material) in a range of entertainment, consumer electronics, personal computer, and mobile devices, and many types of medical, transportation and industrial are far lighter and thinner than traditional cathode ray tube (CRT) television.

Flexible, stretchable electroluminescent fibers are of significance to meet the escalating requirements of increasing complexity and multifunctionality of smart electronics. We report a stretchable alternating current electroluminescent (ACEL) fiber by a low-cost and all solution-processed scalable process.

The ACEL fiber provides high stretchability, decent light-emitting performance, with. There was little difference between the electron-only devices over time, but the hole-only device for the QDLED with worse charge balance experienced a much greater increase in driving voltage, pointing to hole current as a major factor affecting the QDLED lifetime.
