1. A wireless communication apparatus comprising:
- a pixel array including a first display pixel and a second display pixel, the first display pixel including a liquid crystal display (LCD) cell in circuit with a transistor and a pixel activation voltage common line;
a display controller;
a pixel activation line in circuit with the display controller to carry a display activation signal from the display controller to the pixel array, the display activation signal to activate visual display of at least one of the first display pixel or the second display pixel;
a frequency multiplexer to multiplex a wireless communication signal and the display activation signal for transmission via the pixel activation line; and
an antenna controller to transmit the wireless communication signal through the pixel activation line and the pixel activation voltage common line.
