TFT LCD panellerde termal analiz ve numerik bir çalışma

According to television or in short TV?s worldwide market surveys and sales figures show that passing from CRT (Cathode ray tube ) televisions to LCD (Liquid Crystal Display) televisions has been swiftly increasing. Producing of CRT televisions is decreasing and comes to an end gradually. New television technology in the design of LCD TV has swiftly improved in recent years. TFT (Thin Film Transistor) panels used in LCD television are divided into two panels as CCFL (Cold Cathode Fluorescent Lamp) panel and LED (Light Diffuser diode) panel.This project aims to provide solutions for the 32inc LED panel thermal problems which are the reasons of increasing expenses, reducting of the life-time of the panel, worsening the quality of the image by using computer aided analysis programme and experimental tools.LED Panel?s normal working conditions of temperature characteristic will be determined with the help of computerized analysis program, the experimental studies and the resulting values of analysis program are compared between each other. Which parts of the panel affected by the temperature is determined by uncovering of the temperature distribution in the Panel. Improvement works will be made on available design by taking into consideration of the affected parts.With this project, LED panel which will be produced in VESTEL by making the analysis of the heat, heat-source problems that may occur will be to minimize at the design phase. This project which is wanted to be carried out within the scope of a master thesis between VESTEL Electronics Inc. and Dokuz Eylul University, Graduate School of Natural and Applied Sciences, Mechanical Engineering Department, Energy Program
