摘要：
A new built-in trimming scheme boosting the OLED driving current through analog programming of the driver p-channel TFT is proposed. By using a selective programming operation, the current variation on the LTPS panel can be reduced to less than 1%. Another blanket-boosting method is investigated for concurrent programming of the entire panel. This blanket-boosting scheme has been successfully demonstrated on a 2.4-in. AMOLED panel where the non-uniformity improved from 8.1 to 4.9% under a worst-case condition.
