Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.

An electronic device having a liquid crystal shutter is disclosed. A liquid crystal shutter is provided in an area formed by expanding a liquid crystal display. The liquid crystal shutter includes a rear polarizer, a rear glass substrate, a segmented electrode, a liquid crystal, a counter electrode, a front glass substrate, a shutter aperture, and a front polarizer. A camera module is disposed behind the rear polarizer. A voltage applied to the segmented electrode can be controlled to visually expose or hide the lens of the camera module from a shutter aperture.
