This disclosure relates generally to interfaces between memory modules and circuit boards. More specifically, this disclosure relates to interfaces for coupling a memory module to a circuit board such that the memory module is arranged in a plane that is substantially parallel with a plane of the circuit board. Various embodiments disclosed herein include interfaces, memory modules including interfaces or portions of interfaces, and/or circuit boards including interfaces and/or portions of interfaces. Associated devices and systems are also disclosed.

A PCB underneath the display panel includes a plurality of insulation layers and one or more metal layers disposed between two adjacent insulation layers out of the plurality of insulation layers. A lower structure is disposed between the display panel and the PCB. At least a portion of a metal layer among the one or more metal layers that is most adjacent to the lower structure is exposed, and the lower structure is electrically connected to the exposed portion of the metal layer. Such exposed portion of the metal layer is electrically connected to the lower structure, so that the area where the PCB is referenced to the ground potential is increased. As a result, residual voltage, residual current in the PCB and noise caused by electromagnetic fields generated thereby can be reduced.
