Abstract
An active matrix liquid crystal display assembly including a flex circuit for interfacing substantially all of the row and column address lines of the display panel with a display output controller. The flex circuit is preferably made of two planar sheets laminated to one another, the first flex circuit sheet interfacing the row address lines with the display output controller and the second sheet interfacing the column address lines of the active matrix with the controller. The flex circuit includes a plurality of extension members, each extension member being electrically adhered to a driver TAB mounted to a peripheral side of the display panel.
