Display device, driving apparatus for the display device and integrated circuit for the display device

摘要

A driving apparatus and a circuit for a display device are presented. The driving apparatus includes a plurality of pixels, a positive polarity reference gray voltage generator capable of generating a plurality of positive polarity reference gray voltages, and a data driver capable of generating a plurality of negative polarity reference gray voltages based on the positive polarity reference gray voltages. The data driver is also capable of generating a plurality of positive polarity gray voltages and a plurality of negative polarity gray voltages using the positive polarity reference gray voltages and the negative polarity reference gray voltages, respectively, and applying gray voltages to the pixels. The gray voltages correspond to external image signals and are selected from the positive and negative gray voltages. The invention simplifies the design of the driving apparatus and circuitry for a display device.
