Abstract: A plurality of thin film transistors (TFTs) and a plurality of photo detectors (PDs) are disposed inside a display component. The plurality of PDs convert detected light into electrical signals. The plurality of PDs and the plurality of TFTs are disposed on two opposite inner side surfaces of a same layer of the display component. Projections of the plurality of PDs and the plurality of TFTs on a first plane are alternately distributed, and the first plane is a plane on which the layer at which the plurality of PDs and the plurality of TFT layers are disposed is located. Fingerprint recognition accuracy can be improved by configuring a display screen including the display component provided in the embodiments of this application. In addition, PDs of different quantities are flexibly arranged, to ensure that a large region of the display screen can be used for fingerprint recognition.

Abstract: A decorative metal finish for a part with a non-conductive surface where the non-conductive surface is lightly roughened to improve its adherence capabilities. A thin metal layer is electrolessly deposited on the lightly roughened surface to provide a bright durable metal finish on the non-conductive surface. An translucent finish is deposited over the thin metal layer to provide protection for the metal finish.

Abstract: A process for preparing a chrome substrate for application of a polymer coating, wherein the substrate preparation enhances adhesion and durability of the adhesion between the chrome substrate and the polymer coating, involves contacting the chrome substrate with an acid solution for a period of time sufficient to modify the surface of the chrome substrate. In certain embodiments, the acid treatment is an anodic treatment. In accordance with certain aspects of this invention, the acid treated chrome surface is further treated with a silane compound to enhance adhesion with a subsequently applied polymer coating composition.

Abstract: A process that can be uniformly employed for electroplating a wide variety of different non-conductive substrates, including those that are non-platable or difficult-to-plate using conventional electroless and electrolytic plating techniques involves application of a platable coating composition to the substrate prior to plating. The platable coating composition is cured to render the substrate more receptive to conventional plating techniques. In one embodiment, the process utilizes an epoxy resin system that upon being cured is receptive to electroless plating and electrolytic plating techniques that are the same or similar to those conventionally employed for electroplating ABS and/or PC/ABS substrates.

Abstract: A process of selectively plating a metal pattern on the surface of a plastic component allows intricate and/or fine patterns of metal to be precisely electroplated onto either a two-dimensional or three-dimensional contoured surface of a plastic article or substrate. The selective metal plating may be either a decorative pattern or a functional pattern, such as for an electrical circuit. The process generally comprises electrolessly depositing a metal coating on the surface of a plastic component, depositing a photoresist coating over the electrolessly deposited metal, imaging and developing the photoresist coating to form a desired patterned photoresist, electroplating a metal on the electrolessly deposited metal that is exposed through the developed photoresist pattern, and stripping the cured photoresist coating and electrolessly deposited metal underneath the cured photoresist coating without damaging the decorative or functional electroplating.
