  • Patent number: 11353759
    Abstract: Active matrix backplanes including an array of hexagonal electrodes or an array of triangular electrodes. Because the backplane designs route the gate lines along the periphery of the electrodes there is less cross talk with the surface of the electrode. The disclosed designs simplify construction and control of the electrodes and improve the regularity of the electric field above the electrode. Such backplane electrode designs may be particularly useful in electrowetting on dielectric (EWoD) devices and electrophoretic displays (EPD).

  • Patent number: 8599347
    Abstract: An object is to provide a display device in which a difference in load capacitance between wirings is reduced in the case where different signals are supplied to plural pixels at the same timing with use of plural wirings; thus, deviation in the grayscale and/or signal delay can be reduced. The display device includes first to N-th (N is a natural number of 3 or larger) data lines for supplying different video signals; and a pixel including a selection transistor connected to one of the first to N-th data lines. The first to N-th data lines intersect with each other so that one of the first to N-th data lines is provided closest to one terminal of the selection transistor and connected to the one terminal of the selection transistor.
