| Abstract [eng] |
Electroluminescence is an optical phenomenon and electrical phenomenon caused by electron energy change in the electric field. The research aims to determine strength of the luminescence range dependence of power supply voltage. Furthermore, colour coordinates were calculated and change of the colour from purple to greenish were determined. The paper consists of several chapters, that present design of screen printing technology, labour costs calculations, technological processes, quality requirements, selection of equipment and preparation and production stages, demand for labour force, work safety and ecology factors, health risks, action plan of hazard reduction, ecological issues, analysis of innovation installation, and key economic indicators. |
