摘要
Abstract This work proposes an external real-time compensation method based on a look-up table to compensate for the IR drop. With the trend of 3C products increasing screen size and resolution, the decline of panel uniformity has become a problem that must be solved. In this work, the matrix is established with the equivalent circuit model of the panel. The voltage drop of different brightness is calculated iteratively according to the electrical properties of TFT and OLED to correct the preset Vdatas of the original brightness and store it in the look-up table. The uniformity after compensation is verified by 9 points. Experimental results show that IR Drop prediction error controlled within 3.8%, and the uniformity after compensation reached 99.647%.
