    摘要: The liquid crystal display device has at least a liquid crystal panel, a signal line driver for driving signal lines in the liquid crystal panel, and a scanning line driver for driving scanning lines. To prevent waveform distortion due to a high output impedance of the signal line driver from causing adverse effects on a displayed image, a control means is provided which causes display signals to be written to pixel electrodes in the liquid crystal panel so as to avoid amplitude variation periods of the display signals. According to a preferred embodiment, the control means consists of a display signal delay circuit, a scanning signal delay circuit, and a display timing controller that control the signal line driver and the scanning line driver.

    摘要: An active matrix type liquid crystal display device wherein a correcting voltage having an absolute value larger than that of a feed-through voltage of the liquid crystal element is applied to a pixel electrode through a storage capacitor, when the liquid crystal has positive dielectric anisotropy and a positive voltage is applied to the pixel electrode, and when the liquid crystal has negative dielectric anisotropy and a negative voltage is applied to the pixel electrode. As the signal voltage value corrected through the storage capacitor can be changed depending on the signal voltage value of the previous field, a voltage to be applied to the liquid crystal can be corrected in advance to emphasize a change in a motion image.

    摘要: A plurality of pixels are arrayed in a matrix format on the liquid crystal panel of a liquid crystal display. GH liquid crystal layers and transparent electrodes for displaying a plurality of different colors are alternately stacked on a reflecting plate, and therefore each pixel has three liquid crystal layers. Pieces of potential information supplied to the respective liquid crystal layers are controlled by switching elements connected to signal lines and scanning lines. The signal lines and the scanning lines are respectively connected to driving ICs, which are connected to a signal processing circuit. In each pixel, while the potential information of one liquid crystal layer is controlled, the remaining liquid crystal layers are set in a floating state.
