A video dot intensity balancer for use in a video display system wherein information is represented by a series of logic bits in a video stream corresponding to dots to be displayed on a CRT is disclosed. Logic elements are coupled to the output of a bit generator for comparing adjacent bits and outputting an information-defining signal wherein a single information-defining bit never stands alone. In this manner, apparent intensity imbalances on the video screen are eliminated.

Video dot intensity balancer

A dynamic read only memory (ROM) which comprises a memory select precharge section, a memory select section, a memory section, a memory precharge section and a plurality of grounding devices. The ground reference for the pulldown transistors is selectively activated at an appropriate time such that the memory sections are active only for a relatively brief portion of the memory cycle, thereby reducing dc power consumption and simplifying the driver circuit.
