Abstract: A liquid crystal display device includes a first substrate, a pixel array formed on the first substrate, a transparent substrate, a liquid crystal layer disposed between the pixel array and the transparent substrate, a transparent electrode disposed between the transparent substrate and the liquid crystal layer, and an input electrode. The transparent electrode has a longer first edge and an orthogonal shorter second edge. The input electrode extends along, and is electrically coupled along, the first edge of the transparent electrode and has lower impedance than a portion of the transparent electrode overlying the pixel array. The input electrode can include additional portion(s) that extend along, and that are electrically-coupled along, the other edges of the transparent electrode. The input electrode reduces the common voltage propagation delay across the transparent electrode and improves reduces intensity variation over the display area, even for high-frequency common voltage waveforms.

Abstract: An image sensor includes a photosensing element for receiving infrared (IR) radiation and detecting the IR radiation and generating an electrical signal indicative of the IR radiation. A redistribution layer (RDL) is disposed under the photosensing element, the RDL comprising pattern of conductors for receiving the electrical signal. An IR reflection layer, an IR absorption layer or an isolation layer is disposed between the photosensing element and the RDL. The IR reflection layer, IR absorption layer or isolation layer provides a barrier to IR radiation such that the IR radiation does not impinge upon the RDL. As a result, a ghost image of the RDL is not generated, resulting in reduced noise and improved sensitivity and performance of the image sensor.

Abstract: A curved-surface image-sensor assembly has a porous carrier having a concave surface with a thinned image sensor bonded by an adhesive to its concave surface of the porous carrier; the porous carrier is mounted into a water-resistant package. The sensor assembly is made by fabricating a thinned, flexible, image-sensor integrated circuit (IC) and applying adhesive to a non-illuminated side of the IC; positioning the IC over a concave surface of a porous carrier; applying vacuum through the porous carrier to suck the IC onto the concave surface of the porous carrier; and curing the adhesive to bond the IC to the concave surface of the porous carrier.

The first part and the second part are positioned such that the first transparent conductive layer is facing the second transparent conductive layer. A first end of the first transparent conductive layer is electrically connected to a first terminal of a capacitance monitor, and a second end of the second transparent conductive layer is electrically connected to a second terminal of the capacitance monitor. The capacitance monitor constantly monitors the capacitance across the first transparent conductive layer and the second transparent conductive layer during an operation comprising diffracting a laser beam.
