Abstract:
1. An LCD with an integrated touch panel, comprising: a thin film transistor array panel comprising: a common electrode panel disposed on the thin film transistor array panel and comprising a common electrode, wherein the first sensor line and the second sensor line are connected to first and second electrodes formed on the first insulating substrate, respectively, and wherein a common voltage applied to the common electrode is applied to the first sensor line and the second sensor line through the first and second electrodes when an external pressure is applied to the touch panel in the vicinity of the electrodes; and a first comparator connected to the first sensor line and the first dummy line and amplifying a voltage difference between the first sensor line and the first dummy line and then outputting the amplified voltage difference; and, a second comparator connected to the second sensor line and the second dummy line and amplifying a voltage difference between the second sensor line and the second dummy line and then outputting the amplified voltage difference.
