Abstract
An inductive cooktop includes a transparent panel that supports a cookware object. An electrically actuated panel, such as a display panel, is disposed below the transparent panel. The electrically actuated panel includes two sets of lines, such as data and scan lines, disposed orthogonal to each other to form a two-dimensional matrix that is configured to operate associated elements with an addressing scheme. An array of induction coils are disposed below the electrically actuated panel that are each operable to generate an electromagnetic field that inductively couples with the cookware object supported at the transparent panel. The induction coils are operable to generate an electromagnetic field with a flux direction in general parallel alignment with one set of lines, such as the data lines, to prevent the electromagnetic field from inducing a voltage on the lines.
