Abstract

Engineering (all)
A new built-in trimming scheme boosting the driving current through analog programming of the driving pTFT is proposed. The current variation on the panel can be controlled within 1%. This blanket boosting scheme is demonstrated on a 2.4-inch AMOLED panel with non-uniformity improved from 8.1% to 4.9%.
