OLED顯示器是利用電流驅動顯示,當面板尺寸增加時,整體電流量增加,造成耗電量也跟著增加,為了減少耗電量,除了改善材料的發光效率外,設計穩定的驅動電路,亦可以降低消耗功率,達到節能的效果。
本論文提出,由6顆TFT所構成的主動式電流鏡驅動電路,控制OLED的電流,在OLED的量子效率為1﹪與發光亮度是300cd/m2的條件下,只需供應7伏特電壓與2μA的驅動電流,消耗功率低,跟相關文獻比較,有達到節能的效果。
The principle of OLED is utilizing current drivers to show display. Therefore, if the size of the flat panel displays become larger, the total current that flat panel displays needed will also increase. In order to reduce the power consumption, not only the luminescence efficiency of the material should be improved, but also a stable circuit be designed.
In this thesis, a method which uses active matrix current mirror circuit with six TFT to control the current is proposed. In this case, if the quantum efficiency of an OLED is 1% and the luminescence is 300cd/m2, the proposed circuit only requires 7V and 2μA. Compare to others, this result is better than theirs. It can achieve a lower power consumption and thus energy efficient.
