Abstract
In a liquid crystal display, complementary signal lines for data lines are provided, corresponding to columns of pixels arranged in a display pixel matrix. In a refresh mode, data of these pixels are read out on the complementary signal lines, and differentially amplified by a sense amplifier. The data differentially amplified is written in the original pixel. A refresh operation is carried out internally and there is no need for externally providing a refresh memory for storing data used in refreshing the pixel data. Thus, it is possible to reduce the current consumption for holding data of pixels.
