    摘要: The present invention provides a display device which can display characters clearly and display images smoothly. An area gray scale method is adopted and a configuration of one pixel is changed depending on a mode, by selecting one or more display regions in each pixel. When characters are needed to be displayed clearly, one pixel is configured by selecting a stripe arrangement. Thus, clear display can be conducted. When images are needed to be displayed, one pixel is configured by selecting an indented state. Thus, smooth display can be conducted.

    摘要: There is no method combining advantages of both an analog gray scale method and a digital gray scale method. An object is to provide a means that can perform display in a plurality of display modes. In a display mode-specific video signal generation circuit, an input video signal is output as an analog value without any change, as a binary digital value, and as a multi-valued digital value. As a result, a display gray scale of a pixel changes in a timely manner. Accordingly, a clear image can be displayed. In other words, an analog signal and a digital signal are switched and input to a source driver. In addition, the display device also includes a means that switches and outputs an analog signal and a digital signal. By using such means, the display device can have the advantages of both the analog gray scale method and the digital gray scale method, thereby achieving the above object.
