本論文中,主要採用Microchip 公司 PIC16F73 & PIC16F873 Microcontroller晶片作為硬體平台,Microchip Integrated Development Environment Software Tool (MPLAB IDE X.X)作為設計實驗樣品的軟體環境。設計了一個全自動亮度檢測系統,可量測面板燈箱內部之亮度強度,據以控制背光燈管驅動電流大小之,以達到在LCD面板使用期間獲得穩定背光亮度與延長面板壽命之目的。
In this thesis, we choose Microchip PIC16F73 & PIC16F873 Microcontroller chip for the hardware platform, and Microchip Integrated Development Environment Software Tool (MPLAB IDE X.X) for the sample KIT design software environment. This study proposes an automatic backlight detection system which can measure the intensity of backlight and provide a feedback signal for controlling the driving current of backlight tube to stabilize backlight intensity and then extend the lifetime of the LCD panel.
