[[alternative]]Research for Cold Cathode Fluorescent Lamp Dimming

碩士機電工程學系[[abstract]]液晶電視之背光與調光之技術在盧昭正 教授尚未發明脈波頻率調變(Pulse Frequency Modulation，在此簡稱PFM)技術之前，全世界皆採用脈波寬度調變(Pulse Width Modulation在此簡稱PWM)之技術，本研究之目的在設計一電路以証明盧昭正 教授所發明之方法可以實現冷陰極管(Cold Cathode Fluorescent Lamp，在此簡稱CCFL)能做為背光照明及調光之功能，並將脈波寬度調變技術與脈波頻率調變技術做一比較，以提供學術界與科技界之參考或引用。[[abstract]]Before the invention of Prof. Dr. Lu, Chao-Cheng, Pulse Frequency Modulation (PFM), Pulse Width Modulation (PWM) has been applied in most of the electronic design very popularly. This research proves the invention of Prof. Dr. Lu, PFM, physically works better in driving and dimming circuits of the Cold Cathode Fluorescent Lamp (CCFL) backlight compares with PWM circuits
