摘要

The study aims at investigating the fluidic and thermal fields at the vertical section of a 23-inch commercial TFTLCD TV panel through both numerical simulation and experimental validation. Twelve cold cathode fluorescent lamps (CCFLs) of backlight module of TFT-LCD panel are located in the vertical-trapezium enclosure space from top to down. The CCFLs heat up ambient air by heat conduction and form plume flow by buoyancy and gravity. Because of these CCFLs' influence, natural convection phenomenon exits in the backlight module. The simulation of temperature distribution for transient and steady state is done with conditions of two dimensional laminar flow and incompressible properties in the natural convection. Subsequently, the temperature distribution on the TV panel is compared via heat conduction. The study conducts a reliable verification process. The transient temperature distribution in the direct-type backlight module and LCD panel is measured by K-type thermocouples. Based on the measurement, the buoyancy effect and flow field that influence the direct-type backlight module are further discussed.
