@@@@In order to achieve uniform display and solve the cross-talk effect of passive matrix OLED screen, the structure of OLED and the characteristic of PM-OLED driving technology are analyzed and the passive driving technologies of OLED described. Then the current source and pre-charging technology are used to improve the display uniformity. Finally, the causes of cross-talk effect are discussed and the driving circuit of reverse voltage restraint is used to make the unselected pixel in cut-off state, thus effectively solving the influence of cross-talk effect on OLED is uniform display.
