Abstract:
The invention relates to a printed circuit board (1) with at least two connection points (3) and at least one precision resistor (2) for measuring a current flowing between the connection points. The aim of the invention is to inexpensively produce a printed circuit board of the type mentioned in the introduction such that the printed circuit board has a reduced installation space while simultaneously having a preferably long service life. According to the invention, this is achieved in that the precision resistor extends between the connection points in the printed circuit board (11). The invention additionally relates to a corresponding method for producing said printed circuit board.
Abstract:
An electronic device may be provided with an organic light-emitting diode display with minimized border regions. The border regions may be minimized by providing the display with bent edge portions having neutral plane adjustment features that facilitate bending of the bent edge portions while minimizing damage to the bent edge portions. The neutral plane adjustment features may include a modified backfilm layer of the display in which portions of the backfilm layer are removed in a bend region. A display device may include a substrate, a display panel on the substrate having display pixels, and peripheral circuitry proximate the display panel and configured to drive the display pixels. A portion of the periphery of the substrate may be bent substantially orthogonal to the display panel to reduce an apparent surface area of the display device. The bent portion may include an electrode for communication with the peripheral circuitry.
