ABSTRACT:
A matrix addressable display includes an array of emitters aligned to respective regions of a cathodoluminescent layer. Each of the emitters is driven by a respective driving circuit in response to an image signal. Each of the driving circuits includes components selected according to an activation-to-emission response of the respective region of the cathodoluminescent layer. In one embodiment, the driving circuits include storage capacitors having capacitances that correspond to the activation-to-emission response of the region of the cathodoluminescent layer. In another embodiment, the driving circuits include identical capacitors that are charged and discharged in response to pulsed charging and driving signals. By adjusting the pulsed charging and driving signals, the amount of charge transferred to the emitter can be adjusted to compensate for the activation-to-emission response of the respective region of the cathodoluminescent layer.
