ABSTRACT:
A monolithically integratable display apparatus for receiving a picture signal having frames of video information and horizontal and vertical synchronizing components includes a matrix of display cells arranged in an array of M rows by N columns. Display cells in the matrix are individually addressable by row and column signals so as to receive the video information in the picture signal in response thereto. A first shift circuit coupled to the matrix provides the row signals in response to a first clocking signal and a data signal. A second shift circuit coupled to the matrix provides the column signals in response to a second clocking signal. A first clock circuit, such as a phase locked loop, receives the horizontal synchronizing component of the picture signal and produces the second clocking signal in response thereto. A synchronizing detector circuit receives the vertical synchronizing component of the picture signal and produces the data signal in response thereto. A synchronizing regenerator circuit provides a substitute data signal if it fails to receive the data signal, the substitute data signal being based on a vertical synchronizing component from a previous frame of video information.
