CAPACITIVE TWO DIMENSIONAL TABLET WITH SINGLE CONDUCTIVE LAYER ABSTRACT A new capacitive tablet has a single layer in which electrodes provide capacitive coupling with a pen to produce signals that correspond to the X and Y dimensions of the position of the pen on the tablet. The electrodes in the single layer are in the form of pairs of complementary shaped, closely adjacent, conductive elements that extend in the Y dimension of the tablet. For sensing the pen position in the Y dimension, an alternating voltage is applied between the two elements of a pair and the pen receives a signal that is a function of the pen position in the Y dimension. The tablet includes a number of such pairs, each having a different X dimension position, and for sensing the pen position in the X dimension, the two electrodes of a pair are given an alternating voltage that differs progressively across the X dimension of the tablet.
