摘要： A current control circuit for LED or OLED sub-pixels or pixels of an active matrix display is able to store bits or a bit of a control signal used to drive a pixel or sub-pixel, in a memory associated with each pixel or sub-pixel. The control circuit elements can be made compatible with thin-film processing such as to produce thin-film transistors.
