    摘要： 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.

    摘要： An image acquisition apparatus, a terminal device, a liquid crystal terminal device and an image acquisition method are provided according to the disclosure. The image acquisition apparatus includes an imaging plate and an image sensor disposed to be spaced apart from one side of the imaging plate. The imaging plate is provided with an imaging pinhole corresponding to the image sensor. The liquid crystal terminal device includes an LCD panel and a backlight element. The image acquisition apparatus is disposed at a position corresponding to the LCD panel within the backlight element. The image acquisition method includes acquiring an image of an object to being scanned by the image sensor through the imaging pinhole at a side of the imaging panel. An ultrathin fingerprint scanner can be formed based on pinhole imaging principle in the disclosure, and can be further combined with an LCD screen to accomplish fingerprint acquisition function. Alternatively, an ultrathin image acquisition device can be formed to acquire an image of a general object. This can significantly reduce the size and thickness of an image acquisition module in the device and greatly facilitate the implementation of mobile devices and embedded devices with an image acquisition function.
