摘要： A driving device for a display apparatus and a driving method for the same are provided. In the driving device, scanning signals and data signals having a plurality of periodical inactive portions in one frame are applied to respective display dots. In the inactive term, a fixed voltage is applied to each of the display dots. The signal applied to the display dot is divided into small terms by the inactive portions, resulting in higher frequency components in the voltage signal applied to the display dot. As a result, the frequency components of the driving signal applied to the display dot are averaged. Further, a complete orthogonal function having 2 r base function series is used, and a desired display data is completely reproduced on the display apparatus by an arithmetic process assuming auxiliary data in accordance with the number of the scanning electrodes.
