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.

A system for improving a display coupled to an inductive cooktop includes an induction coil and an electrically-actuated display (EAD) assembly. The induction coil includes a magnetic field. The EAD assembly is disposed on the induction coil and includes a frontplate adjacent to the induction coil and a thin film transistor (TFT) array backplane opposite the frontplane. The TFT array backplane includes a scan line with some degree of orthogonality to the magnetic field and a data line with some degree of parallelism to the magnetic field. The scan line and the data line are configured to activate a display pixel corresponding to the EAD assembly. One or more ground lines of the EAD assembly have some degree of parallelism to the magnetic field of the induction coil.

An inductive cooktop system includes a top plate that has a top surface for supporting a cookware object. A display is disposed below the top plate, and induction coils are arranged in a matrix and disposed vertically below the display. The induction coils are each operable to generate a magnetic field that partially extends above the top surface of the top plate to couple with the cookware object. A control system receives an initial input indicating a position of the cookware object on the top surface of the top plate. Data processing hardware of the control system then determines the pixels of the display corresponding to the indicated position from the input. The control system then generates a graphic at the indicated position for the cookware object by illuminating the plurality of pixels of the display.
