Abstract
A novel external VT compensation method, using a simple driving scheme, is presented, enabling high resolution, yet uniform displays, regardless of the size. The uniformity can be maintained for initial VT nonuniformities as well as VT shifts occurring during operation, like bias stress. The characterized display area shows a significant reduction in current variation, transforming ~23% variation without compensation into 0.56% variation after calibration.
