ABSTRACT:
A display device includes an edge-lit light-transmitting sheet having first and second opposed parallel surfaces. A matrix is applied to at least one of the first and second surfaces and comprises a series of lines extending between opposed edges of the sheet. The spacings between the lines and/or the thicknesses of the lines are so chosen as to obtain a desired intensity of illumination at selected areas of the sheet.
