Heat Dissipation of LED Back Light Units Based on TRIZ

LEI Si-Jun,MA Qing,YOON Dae-Keun,SHANG Fei,RYU Bong-Yoel(Beijing BOE Optoelectronics Technology Co.Ltd.,Beijing 100176,China)  
The basic theory and method of TRIZ is introduced,and the heat dissipation problem of LED back light units with conflict matrix is analyzed.As this problem belongs to physics contradiction,this paper puts forward an effective solution for LED back light units' heat dissipation based on conditional separation and scientific effect-phenomenon knowledge base.The result of theoretical analysis and simulation calculation shows that Peltire effect of semiconductor refrigeration has perfect heat dissipation on LED back light units.
