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.

摘要： A liquid crystal display includes a liquid crystal display panel having a pixel matrix consisting of a plurality of pixels, a signal line driver, a row address line driving circuit, a row pixel counter circuit, a row address signal generating circuit, a column address line driving circuit, a column pixel counter circuit, and a column address signal generating circuit. Each pixel includes a liquid crystal unit, a storage capacitor, and a switching unit consisting of switching devices. The switching unit is turned on and off by a cooperation of a row address line and a column address line. While the switching unit is ON, an image signal is supplied from a signal line to a pixel electrode. This reduces write operations to pixels and thereby reduces the power consumption, and also improves the writing characteristic and the holding characteristic which differ from one pixel to another.

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.
