When applied to the TFT-LCD backlight, it can feed back the impact of temperature, to change the states of each color light sources; therefore the panel can get more stable optical quality.At the same time, the temperature distribution of the backlight module is different, reduce temperature feedback effect, therefore need for the regional compensation, reduce brightness differences caused by uneven temperature. Thus, it is simple and effective to stabilize the efficiency of the LED colors system. Using this method of controlling temperature compensation ,the backlight module system can be effectively controlled , below the default color temperature 6500 K , the operating temperature range between 5 ℃ ~ 50 ℃ ,the changes in color temperature of the backlight module can be controlled within 125 k , and △ u ’’ reduced to 0.0011, △ v’’ reduced to 0.0017. en_US DC.subject 溫度控制 zh_TW DC.subject LED zh_TW DC.subject 顏色系統 zh_TW DC.subject temperature control en_US DC.subject color system en_US DC.subject LED en_US DC.title 溫度控制LED光源之顏色系統 zh_TW dc.language.iso zh-TW zh-TW DC.title temperature control system en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
