Uniform active matrix oled displays

摘要

An active matrix display and method of driving the same is provided. The active matrix display comprises an array of pixels, each pixel including an organic light emitting device and at least one thin film transistor. A uniformity correction circuit that is capable of producing a selected pixel brightness is connected to the array of pixels. The uniformity correction circuit is capable of maintaining the brightness of the pixels in a range that does not vary, for example, by more than about 5-10% from their selected brightness values.
