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.

摘要： A liquid crystal display device enabling a reduction in size and costs associated with the system as a whole, starting to display images without image distortion at power on time, and turning the screen off without image retention at power off time, a method of controlling the liquid crystal display device, and a mobile terminal incorporating the liquid crystal display device as a screen display. On a glass substrate (11) provided with a display unit (12), peripheral drive circuits such as an interface circuit (13), a timing generator (14), a reference voltage driver (15), a CS driver (18), a VCOM driver (19), and a voltage regulation circuit (20), together with a horizontal driver (16) and a vertical driver (17) are disposed. When a display reset control pulse PCI is supplied from an external source, a predetermined voltage is written into pixels while a CS voltage and a VCOM voltage adjusted to the same level as that of a pixel voltage are applied to a common-electrode-side. This allows the screen to turn white in a normally white type liquid crystal display, and to turn black in a normally black type liquid crystal display. Image distortion at power on/off time can thus be prevented.

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.

Thus, a level converter circuit in which the consumption of DC current is reduced and which enables reduction in power consumption of the whole device, a display device equipped with this level converter circuit, and a portable telephone device using the display device as an output display unit can be constructed.
