Abstract:
1. A liquid crystal display comprising a liquid crystal display panel and a plurality of driving circuits for driving the liquid crystal display panel, the driving circuits comprising: an input circuit to which digital display data is inputted from outside, a data latch circuit which holds the digital display data, a decoder circuit which selects a gray scale voltage in accordance with the digital display data which is held by the data latch circuit, an output amplifier which outputs the gray scale voltage to the liquid crystal display panel, an output circuit which outputs the digital display data to next-stage driving circuits, data transfer wiring which connects between the input circuit and the output circuit, and a data inversion calculation circuit that inverts the digital display data in accordance with a data inversion signal, wherein the data inversion calculation circuit electrically connects with the output of the data latch circuit, an inversion signal line outputs signals from the data latch circuit and connects to the data inversion calculation circuit, the data inversion calculation circuit includes an exclusive OR circuit, and the digital display data and the data inversion signal input into the exclusive OR circuit.
