  • Patent number: 7456814
    Abstract: The specification and drawings describe and show embodiments of the present invention in the form of a liquid crystal display with a 2-port data polarity inverter. More specifically, the liquid crystal display includes a liquid crystal polarity inversion driver determining whether a polarity of a liquid crystal is inverted and inverting the polarity of the liquid crystal in accordance with the determined result, a first data polarity inversion driver determining whether a first data transition is occurred in first data inverting the polarity of the first data in accordance with the determined result, and a second data polarity inversion driver determining whether a second data transition is occurred and inverting the polarity of the second data in accordance with the determined result.

  • Patent number: 7362291
    Abstract: A liquid crystal display device includes a controller arranged on a data printed circuit board for receiving externally generated video data and clock signals and a resistor for removing electromagnetic noise generated at the controller. Electromagnetic noise such as ESD, interference from other signals, etc., which might be transmitted to a gate driver IC through a resistor formed on a data printed circuit board can be eliminated using a ground voltage and picture quality can be thereby be improved.
