Abstract: Devices for mitigating or stopping noise or surface current on a display are provided. An electronic device including a display may include a display substrate, a mid-support plate that is adjacent to the display substrate, and a lower support plate that is adjacent to the mid-support plate. A space exists between the mid-support plate and the lower support plate. The mid-support plate includes one or more electromagnetic band gap (EBG) structures formed through the mid-support plate, one or more electromagnetic band gap structures mounted onto the mid-support plate, or both. The one or more electromagnetic band gap structures may mitigate or stop surface current flow across the display.

Abstract: Spring clips that provide a reliable, low-impedance, low-harmonic path between various conductive enclosure components of electronic devices. These spring clips can include a low-impedance connection on each of two ends, where each end physically and electrically connects to an enclosure component of an electronic device. This can reduce an impedance between enclosure components and reduce the amplitude and harmonics of signals coupled onto them from a nearby antenna or other waveguide.

Abstract: An electronic device may include an inverter. The inverter may convert direct current (DC) power to alternating current (AC) power. The inverter may use a clock signal at a given frequency to output corresponding alternating current signals at the given frequency. The inverter may receive a dithered clock signal that is frequency dithered using a modulating signal. The dithered clock signal may have at least three different frequency levels during a repeated cycle of the modulating signal. The at least three different frequency levels may include a fundamental frequency, a first frequency that is lower than the fundamental frequency, and a second frequency that is higher than the fundamental frequency. The dithered clock signal may be, during the repeated cycle of the modulating signal, at the fundamental frequency for fewer total periods than at the first frequency and for fewer total periods than at the second frequency.

Abstract: Systems, methods, and devices for diverting surface current on a display panel support plate are provided. An electronic transceiver device including a display panel may include a display back plate and a support plate, such that the support plate is disposed beneath the display back plate. The support plate may include an array of slots etched into the support plate, such that the array of slots may be used and positioned to divert an electromagnetic field on the support plate to redirect propagation of the surface current towards ground pins located on the display panel housing.
