LED 7吋背光模組的設計

Design for LED 7-inch Backlight Module

指導教授 : 黃惠良

摘要


背光模組從液晶顯示器(LCD)背面發光,一般來說,包括一個光源及光學組件。大多的液晶顯示器背光都使用冷陰極螢光燈管(CCFL)來達到此一目的,但是現在我們更換成LED。 在本論文中,我們只有更換CCFL光源為LED。我們使用AutoCAD軟體來建立7吋背光模組,而且我們用TracePro來分析7吋背光模組的光學特性。 模擬7吋背光模組的四個步驟: 步驟一: AutoCAD中建立7吋背光模擬。步驟二: TracePro軟體中使用CCFL來當背光模組的光源得到均勻的出光面。步驟三: 取代CCFL,我們用白光LED做背光模組的光源。步驟四: 使用紅、綠及藍三色LED產生白光。 最後,我們可以得到三種型式的7吋背光模組。這三種型式的7吋背光模組分別是CCFL背光模組、白光LED背光模組及紅綠藍三色LED背光模組。

Backlights illuminate the LCD panels from the rear, and generally consist of a light source and optical components. Mass LCD backlights have used cold-cathode florescent lamps (CCFL) for this purpose, but now we are switching to LEDs. We only convert the light source of CCFL into LEDs. We use AutoCAD software to establish 7-inch backlight modules and analyze optical characteristics of 7-inch backlight modules in TracePro software. Four steps for designing LED 7 inch backlight are below: Step one: Model 7-inch backlight modules in AutoCAD. Step two: Find the uniform output plane using CCFL light source in TracePro software. Step three: Instead of CCFL, we use White LED for light source. Step four: Use three RGB colors LEDs generating white light. Finally, we can get three types of 7-inch backlight modules. Three types of 7-inch backlight modules are CCFL backlight modules, White light LED backlight modules, and Three RGB colors LED backlight modules.
