Abstract:
1. A liquid crystal display (LCD) panel comprised of: a single panel lying in a single plane, having a first plurality of thin film transistors (TFTs) arranged in rows, said rows of TFTs in the panel being capable of displaying images throughout said single panel in a display mode; and a second plurality of TFTs in a fingerprint detection area of the single panel, which is within a first area of the single panel, said second plurality of TFTs being a subset of said first plurality of TFTs said TFTs in the fingerprint detection area being capable of both actively displaying images in said display mode and generating signals that represent a fingerprint touching the single panel in the fingerprint detection area in a fingerprint recognition mode; wherein the single panel further comprises a scan drive unit which sequentially turns on rows of the first plurality of TFTs and the second plurality of TFTs to display images in the display mode, and a data drive unit which outputs data signals to a turned-on row provided in the image display panel, and wherein the fingerprint detection area comprises a switch control unit which sequentially turns on rows of TFTs in the fingerprint detection area in order to perform fingerprint recognition in the fingerprint detection area of the single panel, and a reading unit, to which fingerprint information recognized from a turned-on row is outputted.
