Available in PDF, EPUB and Kindle. Book excerpt: An electroluminescent display panel of the cross-grid-matrix-type was fabricated on a 10-3/4 x 10-3/4-inch glass substrate using improved vacuum deposition procedures and a high brightness manganese-doped ZnS phosphor. This panel contained 256 x 256 active elements within an area of approximately 7 x 7 inches. Linear resolution was 36 elements per inch with a cross-conductor width of 0.020 inch and a separation of 0.007 inch. The display panel was successfully used as a viewing screen for rear-projected images. The brightness-voltage relationship of the thin film phosphor was such that a cross-suppression ratio in excess of 10,000 to 1 was achieved with an excited element brightness of 100 ft-L. Performance measurements indicated that the optimum drive frequency was about 15 kHz. For pulsed operation, a burst frequency of 37.5 Hz, a carrier frequency of 15 kHz, and a duty cycle of 0.25 percent gave an average brightness of a few foot-Lamberts. Useful operating lifetime of several hundred hours under the above conditions was indicated by preliminary data. The variation in brightness uniformity over a group of cells near the center of the panel was less than 7 percent at an average brightness level of 16 ft-L.A brightness reduction of about 12 percent was observed at a single cell when the contacting configuration was varied on the stannic oxide electrode.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses recent developments in electroluminescent (EL) displays, in particular thin-film EL displays, which are all-solid emissive displays with fast response, wide viewing angle, high resolution, wide operating temperature ranges and good display qualities. First, the characteristics of four types of EL devices are presented, and the physics of ac thin-film EL devices are detailed, including ideal models, measuring and evaluation methods, high-field electronic transport and properties of phosphor materials. The book emphasizes recent developments in phosphor materials for color thin-film EL devices based on ZnS, SrS, CaS and CaGa2S4, and multicolor thin-film EL panels in four-panel structures. Other important features discussed are drive methods and reliability issues.

This book was released on 1994 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of an electroluminescent device is presented which facilitates the manufacture of 600 dpi electrophotographic image bar arrays. Matrix addressed laterally emitting alternating current thin film electroluminescent devices, LETFELs, provide intense light sources. Electroluminescent materials are deposited on pre-fabricated 4" Si substrates by RF magnetron sputtering from ZnS:Mn and ZnS:S powder and Y2O3 sintered targets. Silicon thin film technology is utilised to pattern A1 and poly-Si conducting networks which address a linear arrays of LETFEL devices. Micro-fabrication of LETFEL materials by Ar ion sputtering and wet-chemical etching produce via holes for metallisation and light emitting facets. Automated dicing of fabricated wafers define the LETFEL die. Pick-and-place techniques butt die end-to-end to produce a linear array. Implementation of a 6 to 1 level of matrix addressing for the preferred LETFEL die, ensures optimisation of cost, excitation frequency, lateral brightness, manufacturability, yield and the use of presently available drive electronics and assembly processes. High voltage bipolarity pulses combined with low voltage pulse positioning control the LETFEL array. Worst case electrical analysis suggests pulse widths of 5us, which can be configured to 8.3kHz excitation frequency. This corresponds to a forward brightness of 53,000fL for a conventional LETFEL structure and is insufficient for 8ppm printing. A novel barrier layer structure incorporated into fabricated wafers has brightnesses which exceeds the requirement for 8 ppm, when driven at lower excitation frequencies. An efficient out-coupling process has been identified for miniature displays. Presently micro-mirrors fabricated from SiO2 reflect the direct lateral emission through 90 degrees.....

Download or read book Thin Film Growth Techniques for Low Dimensional Structures written by R.F.C. Farrow and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work represents the account of a NATO Advanced Research Workshop on "Thin Film Growth Techniques for Low Dimensional Structures", held at the University of Sussex, Brighton, England from 15-19 Sept. 1986. The objective of the workshop was to review the problems of the growth and characterisation of thin semiconductor and metal layers. Recent advances in deposition techniques have made it possible to design new material which is based on ultra-thin layers and this is now posing challenges for scientists, technologists and engineers in the assessment and utilisation of such new material. Molecular beam epitaxy (MBE) has become well established as a method for growing thin single crystal layers of semiconductors. Until recently, MBE was confined to the growth of III-V compounds and alloys, but now it is being used for group IV semiconductors and II-VI compounds. Examples of such work are given in this volume. MBE has one major advantage over other crystal growth techniques in that the structure of the growing layer can be continuously monitored using reflection high energy electron diffraction (RHEED). This technique has offered a rare bonus in that the time dependent intensity variations of RHEED can be used to determine growth rates and alloy composition rather precisely. Indeed, a great deal of new information about the kinetics of crystal growth from the vapour phase is beginning to emerge.
