  • Patent number: 11397367
    Abstract: Resistive bridges can connect many ring electrodes in an electro-active lens with a relatively small number of buss lines. These resistors are usually large to prevent excessive current consumption. Conventionally, they are disposed in the same plane as the ring electrodes, which means that the ring electrodes are spaced farther apart or made discontinuous to accommodate the resistors. But spacing the ring electrodes farther apart or making them discontinuous degrades the lens's optical quality. Placing the ring electrodes and resistors on layers separated by an insulator makes it possible for the ring electrodes to be closer together and continuous with resistance high enough to limit current consumption. It also relaxes constraints on feature sizes and placement during the process used to make the lens. And because the resistors and electrodes are on different planes, they can be formed of materials with different resistivities.

  • Patent number: 11284520
    Abstract: An input device includes a sensor unit, an optical layer superimposed on the sensor unit, and a flexible wiring substrate having a connection region held between the optical layer and support base member. The flexible wiring substrate has a flexible base member on which an electrode layer is provided and a wiring end that is an end of the electrode layer and is conductive with the terminal part with a conductive joining member. The wiring end is set back from an end of the flexible base member, so that the flexible base member has a protruding part protruding toward the sensing region. Since the input device has, on the sensing region side relative to a front end of the protruding part, a part into which the conductive joining member does not stick out, an air bubble region between the sensor unit and the optical layer can be narrowed.
