A liquid crystal display apparatus includes a liquid crystal display unit, a plurality of data driving units which provide image data to said liquid crystal display unit, and a control unit which enables said plurality of data driving units to take in the image data simultaneously if the image data to be provided to said data driving units are identical.

Liquid crystal display apparatus and reduction of electromagnetic interference

Polarity patterns (polarity pattern signal POL) are stored in a ROM in a polarity pattern controlling portion. Then, the polarity pattern is changed according to applications of a liquid crystal display panel. Since the polarity pattern is stored in the ROM, the polarity pattern can be changed without modification of a hardware. Also, two sets of polarity patterns or more are stored in the ROM, and then any one polarity pattern can be output according to the application. In addition, the polarity pattern signal POL and image signals RGB are compared with each other, and then the polarity pattern which is to be read from the ROM is switched according to the result.

Display panel driving method, display panel driver circuit, and liquid crystal display device

A reference potential generating circuit for liquid crystal display apparatus includes an outside reference potential generating circuit for generating a pair of outside reference potentials, and an inside reference potential generating circuit for generating a pair of inside reference potentials, which are between the outside reference potentials and are independent of the outside reference potentials. The outside or the inside reference potential generating circuit has a variable resister for correcting a deviation of a center potential of the outside or inside reference potentials.
