  • Patent number: 4804254
    Abstract: An arrangement in a display or instrument board of the LCD kind, e.g. for use in a car, with said board (10;11) being provided with a matrix network of electrodes (4) for forming arbitrary desired displays all over the visible face of said board. A micro processor (15) is connected to said LCD board to be able to present displays as mentioned, selectively on said board on the basis of information from data suppliers (12-14, 16-19). Said board is flexible due to utilization of monodisperse plastic spheres as a spacer medium, with the remaining layers (1,2,3) provided on each side of plastic spheres (5) and the LC liquid (6) consisting of a flexible material, e.g. plastic sheet or plastic film. Said plastic spheres may be provided with an adhesive-like coating that is curable, so that said plastic spheres are bound to said layers, and the LCD board receives a desired appearance and curvature(s).
