摘要： In the active matrix display device with a DRAM as the retaining circuit, the voltage retained in the retaining circuit is set in the brightness saturation region, which is outside the region of the voltage used in the moving picture display mode. With the voltage in this region, the difference in the brightness will not be recognized even if the voltage decreases before the refreshing operation. This prevents flickering and improves the display quality.

摘要： An LCD device driven with storage capacitors prevents defective image display caused by capacitive coupling between data lines and storage capacitor lines. The LCD device includes pixel electrodes arranged at intersections between drain lines and gate lines, switching elements, storage capacitor lines corresponding to the gate lines, storage capacitors having first electrodes connected to the pixel electrodes and second electrodes connected to the storage capacitor lines, a switching circuit for selectively applying a potential to the storage capacitor lines, and a drain driver. The drain driver selects some of the data lines so that an equal number of image data signals having a positive polarity and image data signals having a negative polarity are provided to the selected data lines and simultaneously provides the selected data lines with the image data signals having a positive polarity and the image data signals having a negative polarity.

摘要： The level of a storage capacitor line changes between two types, an H level and an L level. As a result of this change, the voltage applied to a liquid crystal is shifted so that a sufficient voltage is applied to the liquid crystal to perform a display operation. Then, by changing the voltage value of the difference between a first level and a second level, the contrast and screen brightness are adjusted. Furthermore, the capacitances generated at the locations where the two storage capacitor lines and the data line intersect are set to be substantially the same.
