Patent ID: 7184009

Claim:
An integrated circuit comprising: a substrate; a multiplicity of picture element circuits integrated on the substrate and arranged as a matrix display having a first plurality of rows and a second plurality of columns; a plurality of conductive data lines integrated on the substrate and arranged such that each one of the plurality of data conductive lines is associated with a different column of the matrix display and is directly connected to, always to be in electrical contact with, all the picture element circuits of its associated column; a multiplicity of sensors integrated on the substrate and arranged as a sensor matrix having a third plurality of rows and a fourth plurality of columns; a plurality of conductive row select lines integrated on the substrate and arranged such that each one of the plurality of conductive row select lines is associated with a different row of the sensor matrix and is directly connected to, always to be in electrical contact with, all the sensors of its associated row and also arranged such that each one of the plurality of conductive row select lines is associated with a different row of the matrix display and is directly connected to, always to be in electrical contact with, all the picture element circuits of its associated row; and a plurality of conductive column select lines integrated on the substrate and arranged such that each one of the plurality of conductive column select lines is associated with a different column of the sensor matrix and is directly connected to, always to be in electrical contact with, all the sensors of its associated column, wherein the plurality of conductive data lines are different than the plurality of conductive column select lines such that the columns of the matrix display are selectable in an independent manner relative to the columns of the sensor matrix.
