Abstract:	本計畫係利用近場LED 光分佈程式化技巧來計算背光源快速動態區域控制程式，目標希望程式的背光源建立使用現有邊射型發光二極體(Side Emitting Diodes LED)透鏡，搭配自建數值模擬程式，即時快速運算白光LED 以及紅、綠、藍三色LED 兩種直下式背光模組區域動態控制參數，著重於LED 光源在背光模組下的光場分佈程式化技巧、圖像分析以及背光模組光場數值化控制計算、LED 燈箱區域即時調變技術，如此可快速計算並且分析一背光模組區域動態光源的調變資料，達到高對比度、高效節能的目的，過程中利用光學軟體(ASAP)來模擬比對，針對設計結果打樣白光LED 以及紅、綠、藍三色LED 兩種直下式背光模組配合顯示器系統，進行電氣、光電、光學試驗三方面設計驗證及分析參數之研究，計畫後期將背光源快速動態區域控制程式進行整合，針對所研究之背光模組進行試驗並且回朔優化，針對系統模組技術進行資源連結，建立資料庫因應多種光源及影像改變之系統最佳化自動學習功能，建立出即時動態區域控制高效率節能背光源系統，目標在高亮度、高對比度、光色域下較現行顯示器背光源系統節能 25%以上。This project will use near-field LED light distribution formation skill to calculate backlight fast dynamic control program, the purpose is to use the current side emitting Diodes LED lens to establish the program for backlight. Matching up with the simulation program data, we will instantly calculate the white light LED and red, green, blue LED. By using the above method, we will get two kinds of data for bottom-type backlight unit. We will focus on the light distribution formation skill, image analysis, backlight module light field data control calculation, and LED light box instant tuning skill for LED source in backlight module. Then we can calculate very fast and analyze the dynamic light tuning data for backlight module to achieve high contrast, high efficiency. We will use the Advanced Systems Analysis Program (ASAP) to compare the result in the process. According to the two results we will make samples of bottom-type backlight unit with white light LED, and red, green, blue LED. With monitor system, we will do electronic, optical-electronic, optical experiments to analyze the data.We will integrate the backlight fast dynamic control program at the last stage of the project. Doing experiment and get the feedback to achieve optimization. We will do the information linking between different system to establish the data auto-learning optimization for different light source and image change. Establish high efficient backlight system for instant dynamic control. Our target is to save more than 25% energy during high contrast with the current monitor backlight system. 研究期間：10008 ~ 10107
