Abstract
A matrix display sign and system where the displayed image or message can readily be changed. There is an array of pixel units arranged in rows and columns, and each of these pixel units can be selectively activated to display various selected colors. In a preferred embodiment, each pixel unit is capable of displaying any of a blue, green, red, white or black color. Each pixel unit has an elongate strip member having pixel sections, each having a different color characteristic. The pixel strip is moved in increments so that various pixel sections can be moved into a display region where either reflective light or transflective light illuminates the pixel section. A solenoid driver is activated to move in stepped increments to move the pixel strip to selected positions at the display region.
