Liquid crystal display apparatus with reduced horizontal crosstalk

A circuit, comprising:

• a power supply unit configured to supply a high operating voltage (VDD) signal excluding a common voltage (Vcom);
• a first VDD line configured to transfer the VDD signal to a gamma voltage generator;
• a second VDD line configured to transfer the VDD signal to a data driver;
• and
• a horizontal crosstalk compensation circuit configured to filter high frequency components of the VDD signal supplied from the power supply unit on a circuit board and provided to the gamma voltage generator on the circuit board,
• wherein a flexible circuit board connects the circuit board with a liquid crystal display panel, and
• wherein the gamma voltage generator supplies the gamma reference voltages to the flexible circuit board having the data driver on the flexible circuit board.

An apparatus comprising:

• a liquid crystal display (LCD) panel configured to output images with undesirable horizontal crosstalk effects being suppressed as a result of reducing extreme changes in current that is applied in the LCD panel by using electromagnetic induction,
• wherein the reducing extreme changes in current is achieved by employing a high operating voltage (VDD) signal excluding a common voltage (Vcom) and having high frequency components effectively removed therefrom,
• wherein the VDD signal is transferred via at least one among a first dedicated VDD signal line and a second dedicated VDD signal line, respectively provided to the LCD panel from a gamma voltage generator on a driving circuit board,
• wherein at least one among the first and second dedicated VDD signal lines have the high frequency components effectively removed therefrom by a horizontal crosstalk compensation circuit on the driving circuit board that filters ripples from the VDD signal supplied from a power supply unit on the driving circuit board, and
• wherein a flexible circuit board connects the driving circuit board with the LCD panel, and
• wherein the flexible circuit board includes a data driver thereon, and the gamma voltage generator supplies gamma reference voltages via a gamma voltage line to the flexible circuit board having the data driver thereon.
