Title:
BUILDING CONTROLLER WITH LATERAL SIDE SHIELDING
Document Type and Number:
WIPO Patent Application WO/2022/226711
Kind Code:
A1
Abstract:
A thermostat includes a display having a metal backing, a printed circuit board having a ground plane, and one or more electrical components mounted to the printed circuit board in a shielded region on the printed circuit board between the ground plane of the printed circuit board and the metal backing of the display. One or more conductive side shield elements are positioned between the printed circuit board and the display, extending along and defining the shielded region of the printed circuit board. The one or more conductive side shield elements are electrically connected to the ground plane of the printed circuit board and provide a side shield that reduces Electro-Magnetic Interference (EMI) generated by the one or more electrical components situated in the shielded region of the printed circuit board from escaping laterally out from between the ground plane of the printed circuit board and the metal backing of the display.
