摘要： A selection-addressing-type liquid crystal display selectively addresses a signal line of a pixel unit using groups of three selectors of a selector circuit in a time-division manner. A level converter level shifts selector pulses having a voltage swing corresponding to the external-circuit power supply to selector pulses having a voltage swing corresponding to the internal-circuit power supply. In a non-display region in partial display mode, the level converter is deactivated under the control of a control signal to reduce direct current consumption therein.

摘要： A display device comprising a display panel having pixels arrayed at intersections of mutually orthogonal gate lines and data lines, and a driving circuit for sampling a plurality of video signals simultaneously and distributing the sampled signals concurrently to a predetermined number of data lines; a video driver for relatively delaying the video signals in accordance with the array pitch of the pixels and adjusting the supply timing of the video signals to the display panel; and a timing generator for controlling the simultaneous sampling period of a driving circuit included in the display panel and also controlling the timing of the delay process executed by the video driver. The timing generator is capable of selectively switching the simultaneous sampling period and controlling the delay process timing of the video driver in response to such selective switching to thereby optimize, with respect to the simultaneous sampling period, the supply timing of the input video signals to the display panel. This display device is adapted to prevent occurrence of a vertical streak ghost in a simultaneous multiple-pixel sampling mode.

摘要： A liquid crystal display that is unsusceptible to the effect of a pixel potential during writing of data to a memory, allowing a large margin to be provided against variation in characteristics of transistors forming a pixel circuit, and a portable terminal having the liquid crystal display. In a pixel circuit including a memory circuit (25), separate paths are provided for writing image data from a signal line (16-i) to the memory circuit (25) via a data-write switch (24) and for reading image data held in the memory circuit (25) out into a liquid crystal cell unit via a data-read switch (27). Furthermore, image data are read via a data-read buffer (26). Accordingly, when image data is written to the memory, data held in the memory circuit (25) is not affected by a pixel potential. Thus, a large margin can be provided against variation in the characteristics of the transistors forming the pixel circuit, serving to avoid variation in picture quality due to the variation in the transistor characteristics.

摘要： An active-matrix liquid crystal display device has pixels arranged in a matrix which each include a thin film transistor (TFT) as an active element. When the device is in a power-off state, TFTs in all the pixels are switched on, and all horizontal switches are turned on so that all data lines are supplied with a potential equal to the potential of common electrodes of the pixels. This forms a discharging path for discharging residual charge in all the pixels, and the discharging path can instantaneously discharge the residual charges.
