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.

Electromagnetic band gap structures

Sensing apparatus includes a radiation source, which emits pulses of optical radiation toward multiple points in a target scene. A receiver receives the optical radiation that is reflected from the target scene and outputs signals that are indicative of respective times of flight of the pulses to and from the points in the target scene. Processing and control circuitry selects a first pulse repetition interval (PRI) and a second PRI, greater than the first PRI, from a permitted range of PRIs, drives the radiation source to emit a first sequence of the pulses at the first PRI and a second sequence of the pulses at a second PRI, and processes the signals output in response to both the first and second sequences of the pulses in order to compute respective depth coordinates of the points in the target scene.
