Abstract:
A printed circuit (PC) board-mountable ferrite electromagnetic interference (EMI) filter (702, 1003, 1003") for striplines (701, 1001, 1002) of a printed circuit (PC) board (700, 1000) that accommodates large numbers of striplines, and is cost-effective. One embodiment of the EMI filter is used with a PC board (700) that routes striplines (701) in a step-function (i.e., a "U"-shaped) pattern. The EMI filter comprises a ferrite body (702) that defines two parallel passageways (708, 709), i.e., has a figure-8 shape in cross section. The portion (710) of the PC board that defines the stripline portions extending in the one direction lies in one passageway, whereas the portion (711) of the PC board that defines the stripline portions extending in the other direction lies in the other passageway. A different embodiment of the EMI filter is used with a PC board (1000) that routes sets (1001, 1002) of striplines in a cross-hatch (i.e., a "#"-shaped) pattern, where the striplines end (are interrupted) before intersecting so that each stripline comprises two separate straight on-board parts. This EMI filter comprises a ferrite body (1003) that defines two orthogonal sets (1012, 1013) of off-board "U"-shaped conductors, one set for each orthogonal set of striplines with one conductor of a set for each stripline of a set. Each stripline's corresponding "U"-shaped conductor interconnects the two straight on-board parts of the stripline.
Abstract:
Die Erfindung bezieht sich auf eine Leiterplatte (7) für Steckverbinder in symmetrischen Verteilernetzen der Kommunikations- und Datentechnik. Um einen Steckverbinder zu schaffen, der unter Vermeidung diskreter Kompensationsmaßnahmen für alle Ausführungsarten der Kontaktleiste zwischen allen Kontaktpaaren eine Nahnebensprechdämpfung im Bereich von -60dB erreicht sind die weitgehend parallelen Leiterbahnen (25,26) der Vorderseite nahezu deckungsgleich mit den Leiterbahnen (27,28) der Rückseite der Leiterplatte (7) angeordnet. Die Leiterbahn (28) kreuzt die Leiterbahn (27) mittels zweier Durchkontaktierungen (29, 30), die auf der Vorderseite der Leiterplatte (7) durch eine Leiterbahn (31) miteinander elektrisch verbunden sind.
Abstract:
Bei der Erfindung handelt es sich um eine Steckverbindung (SV) für Computernetze im Hausbereich, in der eine Einrichtung zur Nebensprechkompensation (K1, K2, CK, T1, T2) angeordnet ist. Auf diese Weise wird die Nebensprechdämpfung zwischen der Sende- und Empfangsleiterschleife erhöht, so daß die Kopplungen geringer werden und dadurch die Reichweite vergrößert werden kann. Auf der in der Steckverbindung (SV) befindlichen Leiterplatine (LP) wird die Nebensprechkompensation durch "Auskreuzen" der Verbindungsleitungen oder durch Anordnen von diskreten Bauteilen auf dieser Leiterplatine (LP) durchgeführt.
Abstract:
A light-emitting module according to an embodiment includes a first insulating film with light transmissive property, a plurality of mesh patterns including a plurality of first line patterns and a plurality of second line patterns, a light-emitting element, and a resin layer. The first line patterns are formed on the first insulating film and are parallel to one another. The second line patterns intersect with the first line patterns and are parallel to one another. The light-emitting element is connected to any two of a plurality of the mesh patterns. The resin layer holds the light-emitting element to the first insulating film. A first mesh pattern and a second mesh pattern adjacent to one another among the plurality of mesh patterns have a boundary. Line patterns projecting from the first mesh pattern to the boundary and line patterns projecting from the second mesh pattern to the boundary are collocated along the boundary in a state of being adjacent to one another.
Abstract:
An in-cell touch panel and a display device are disclosed. In the in-cell touch panel, a plurality of mutually independent self-capacitance electrodes (03) arranged in the same layer are disposed on an array substrate in accordance the self-capacitance principle; a touch detection chip (04) can determine the touch position by the detection of the capacitance variation of the self-capacitance electrodes (03); leads (05) arranged in the same layer as pixel electrodes are disposed at gaps between the pixel electrodes and configured to connect the self-capacitance electrodes to the touch detection chip. The touch panel can reduce the manufacturing cost and improve the productivity.
Abstract:
Buffer structures are provided that can be used to reduce a strain in a conformable electronic system that includes compliant components in electrical communication with more rigid device components. The buffer structures are disposed on, or at least partially embedded in, the conformable electronic system such that the buffer structures overlap with at least a portion of a junction region between a compliant component and a more rigid device component. The buffer structure can have a higher value of Young's modulus than an encapsulant of the conformable electronic system.
Abstract:
In the conductive sheets (10, 11) of the present invention, a mesh patter (20) in which multiple openings (18) having different forms are arranged in planar view is formed by means of conductive parts (14a, 14b) which are formed on at least one main surface of a base (12) and which are formed from multiple metal thin wires (16). The standard deviation of the areas of the multiple openings (18) is between 0.017 mm 2 and 0.038 mm 2 . With regard to the two-dimensional distribution of the center position of each of the openings (18), the standard deviation of each center position disposed along a predetermined direction relative to the average square deviation of a position in a direction that is perpendicular to the predetermined direction is 15.0 µm or greater. Or, with regard to the standard deviation along an angular direction in the power spectrum of the mesh patter (20), the standard deviation of said standard deviation throughout the radial direction of a value represented by a common logarithm of is between 0.965 and 1.065.
