Abstract: A PCB underneath the display panel includes a plurality of insulation layers and one or more metal layers disposed between two adjacent insulation layers out of the plurality of insulation layers. A lower structure is disposed between the display panel and the PCB. At least a portion of a metal layer among the one or more metal layers that is most adjacent to the lower structure is exposed, and the lower structure is electrically connected to the exposed portion of the metal layer. Such exposed portion of the metal layer is electrically connected to the lower structure, so that the area where the PCB is referenced to the ground potential is increased. As a result, residual voltage, residual current in the PCB and noise caused by electromagnetic fields generated thereby can be reduced.

Abstract: A liquid crystal display apparatus includes a plurality of sub-pixels configured to be operated by a gate signal transmitted from a gate driver and passing through a gate line and an image signal transmitted from a data driver and passing through a data line, a gamma voltage generator configured to supply gamma reference voltages for expressing gray levels to the data driver, a power supply unit configured to supply a first VDD signal to the gamma voltage generator and a second VDD signal to the data driver and a crosstalk compensation unit positioned between the power supply unit and the gamma voltage generator and configured to filter a ripple of the first VDD signal such that voltage of the first VDD signal is stabilized thereby reducing a level of crosstalk between the sub-pixels adjacent to one another.
