Principle and validation of digital driving for active matrix organic light emitting diodes displays

The feasibility of digital driving has been investigated, which may be an enabling technology for low‐cost, power‐efficient and high‐quality active matrix organic light emitting diodes displays (AMOLED displays). The theoretical requirements therefore are analyzed. Methods for avoiding imaging artifacts are proposed. Results based on two prototypes are presented showing that digital drive is feasible for state‐of‐the‐art manufacturing technology with comparable image quality to analog‐driven AMOLED displays but at lower power consumption and lower production cost.
