  • Patent number: 11475823
    Abstract: An apparatus has a display including a plurality of pixels; and control circuitry configured to selectively control transparency states of the plurality of pixels of the display. The control circuitry includes a multiplicity of cells. A transparency state of one or more pixels is controlled by a state of an associated cell. A cell is configured to provide a propagation signal dependent upon a state of that cell to physically adjacent cells and is configured to receive propagation signals provided by physically adjacent cells. The state of the cell is controllable via addressing and is controllable via the received propagation signals.
