Abstract
A graphical display station of arbitrary shape such as channel letters or other shaped structures is populated with pixels which are components of flexible pixel strings which can be arranged to fit the arbitrary shape(s). The flexible pixel strings provide for straightforward and cost effective fabrication of channel letter or other shaped displays. The invention also includes pixel units which comprise lighting elements together with such control circuits as are needed to properly drive the lighting elements to form a graphical image. Addressing of the particular pixels is provided to accommodate the arbitrary arrangement of pixels of the flexible pixel strings. Methods of fabricating a channel letter display are also disclosed.
