- Abstract
- The voltage distribution of power lines in large Active Matrix Organic Light-Emitting Diode (AMOLED) displays was investigated as a function of panel size, OLED material, power line material and VDD structure in order to improve global brightness uniformity, In addition, the power source voltage distribution was investigated to determine the effect on crosstalk. These results indicate that new OLED materials with high efficiency and VDD lines made of a low-resistance material are essential for AMOLED panels larger than 20 '' diagonally. Crosstalk was found to be due mainly to the abrupt voltage change of the power source on panels. A new mesh VDD structure is suggested as a solution to this problem.
