  • Patent number: 11994784
    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: 11061277
    Abstract: A diffusion sheet, a backlight module, a liquid crystal display panel and a display device are disclosed. The diffusion sheet comprises a base layer, a white printed layer and a black printed layer. The base layer comprises a peripheral region and a light transmitting region. The white printed layer and the black printed layer are arranged in the peripheral region. In a direction from a light incident surface to a light exit surface of the base layer, the black printed layer and the white printed layer are arranged in this order. An orthographic projection of the black printed layer on the base layer falls within an orthographic projection of the white printed layer on the base layer. In this way, the white printed layer can block a shadow which is formed by reflection of the black printed layer from the prismatic sheet, and thus improve the display quality.
