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.

摘要翻译： 提供了一种用于显示装置的驱动装置及其驱动方法。 在驱动装置中，在一个帧中具有多个周期性非活动部分的扫描信号和数据信号被施加到相应的显示点。 在无效项中，对每个显示点施加固定电压。 施加到显示点的信号被非活动部分划分为小项，导致施加到显示点的电压信号中的较高频率分量。 结果，施加到显示点的驱动信号的频率分量被平均。 此外，使用具有2基本功能系列的完整的正交函数，并且通过假设根据扫描电极的数量的辅助数据的算术处理在显示装置上完全再现期望的显示数据。
