ABSTRACT:
An electronic switch matrix for a video projection system has a plurality of switch elements, each of which is associated with a respective one of the display pixels in a MxN array. A first counter, in response to a pixel clock and the horizontal sync signal, provides the column timing for activating the switch elements. Similarly, a second counter, in response to a row block and the vertical sync signal, provides the row timing for activating the switch elements. A switch element activated simultaneously by each counter then couples the luminance signal to a video display circuit element for developing the appropriate pixel intensity.
