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 bicycle saddle lifter is provided which is safe and simple in structure and which can raise the saddle of a bicycle while a bicycle driver is sitting on the saddle. The biasing force of a stroke spring 10 which biases the saddle upwardly is determined such that when the weight of a bicycle driver directly acts on the saddle, the saddle lowers, and when the driver applies force to pedals of the bicycle while sitting on the saddle, and the load on the saddle decreases, the saddle rises. While the driver is not sitting on the saddle, resistance resulting from the biasing force of the stroke spring prevents a ratchet pawl 13b for checking the ascent of the saddle from being disengaged from the corresponding ratchet gear 14 even by switchover operation. While the driver is sitting on the saddle, the biasing force of the stroke spring 10 is canceled by the load applied to the saddle and the resistance decreases, thereby allowing the ratchet pawl 13b for checking the ascent of the saddle to be disengaged from the ratchet gear 14 by switchover operation.
