ABSTRACT:
A system for processing video data to be displayed comprises a controller and a monitor. The controller includes a memory for storing the digital data to be displayed and apparatus for sequentially reading data from the memory. The data from the controller is conducted in digital form to the separately housed monitor separated from the controller. In the monitor, the digital data is converted into analog form and displayed. In the converting process, the digital data is first converted to an analog current and then the analog current is converted to a voltage. An additional voltage-to-voltage conversion may occur to isolate the capacitance of the display device. This system is particularly suited for high resolution systems (greater than 1000.times.1000 pixels) in which a new pixel is refreshed at least every 10 nanoseconds.
