ABSTRACT:
A large liquid crystal display panel, assembled from many smaller sized liquid crystal panels, each carrying a small portion of a larger character or image. The liquid crystals panels may be carried on a common support. For providing the liquid crystal panels, with changeable colors, a new shape of an electrode-matrix is proposed, which have on one inside surface of the liquid crystal panel, electrodes in the form of the desired character or image and on a second inside surface, electrodes in the form of narrow strips, which are disposed on coated narrow strips of different colors. The energization of the electrodes is electronically controlled to effect the appearance of characters or images in different, changeable colors. The large liquid crystal panels can be transmissive, reflective or transflective.
