Abstract:
1. A liquid crystal display comprising: a lower panel having pixels and including a first substrate and a plurality of pixel-addressing gate lines and a plurality of pixel-data supplying data lines disposed on the first substrate; an upper panel including a second substrate, a first sensing unit disposed on the second substrate, a source voltage line, a bias voltage line, and first and second sensing data lines also disposed on the second substrate, the first and second sensing data lines being respectively disposed along and adjacent to opposed sides of at least one of the source voltage line and the bias voltage line; and a liquid crystal layer interposed between the lower panel and the upper panel, wherein the first sensing unit includes a switching transistor electrically connected to one of the first and second sensing data lines and wherein the first sensing unit further includes a sensing transistor electrically connected to the source voltage line and the bias voltage line, wherein the source voltage line and the sensing data line extend in a same direction as do the pixel-data supplying data lines of the lower panel, and wherein at least one of the source voltage line and the bias voltage line directly overlaps a corresponding data line among the pixel-data supplying data lines so as to define a parasitic capacitive coupling with that pixel-data supplying data line.
