Abstract

Double-gated TFT structures are sometimes used to enhance the transconductance of a thin-film transistor. Both gates are connected in parallel in this mode of operation so that the same input signal on both gates modifies the semiconductor conductivity. It is proposed to use a double-gated structure to provide effectively a 2-modulated device which can be used for cursor action, highlighting or any X-Y- 2 operation, in general. In this mode of operation, the gates are not connected in parallel but are separately addressed. One of the gates is the standard signal input gate; the second is only addressed when cursor action, highlighting or logic functioning ("and gates", "or gates") is needed. The signal on the second gate adds to or subtracts from the output generated by the signal gates.
