Abstract
A liquid crystal display apparatus includes a liquid crystal display panel, a data processing circuit, a signal driver circuit, a scan driver circuit, and a power circuit. The liquid crystal display panel includes a plurality of pixels constituted by at least a plurality of pixel electrodes disposed in a matrix arrangement, a reference electrode opposing the pixel electrodes, and a liquid crystal disposed between the pixel electrodes and the reference electrode. The data processing circuit receives input display data and an input synchronizing signal, converts the input display data and the input synchronizing signal to output display data and an output synchronizing signal which are compatible with the signal driver circuit, generates an alternating signal as a timing signal for periodically inverting a polarity of a liquid crystal apply voltage applied to the liquid crystal by the signal driver circuit via the pixel electrodes, and outputs the output display data, the output synchronizing signal, and the alternating signal. A logical voltage level of the output display data output from the data processing circuit is different from a logical voltage level of the input display data received by the data processing circuit.
