A data distributing system wherein an electronic book data storage center which is stored with a plurality of pieces of book data is capable of communicating with electronic book vending machinesvia a communication line and/or a communication satellite. In each of the vending machines, a storage medium can be inserted. The vending machine selects a piece of book data, which may be desired by the user, based on data stored in the storage medium as data to be to recorded into the storage medium. The user himself or herself can select a piece of book data. Also, the recorded data can be deleted from the storage medium in compliance with the user's request. These vending machines may have a function of casting accounts.

Data distributing system and data recording method

A display device which has a liquid crystal display which has a plurality liquid crystal pixels arranged in a matrix and which writes an image thereon after resetting the liquid crystal. The method of writing on the liquid crystal display can be selected from driving methods according to interlace scanning in which a frame is divided into a plurality of fields and writing by interlace scanning is performed and driving methods according to sequential scanning in which scanning lines are subjected to writing serially. When high-speed writing is required, for example, when display of a motion picture, display of inputted letters or scroll display is desired, one of the driving methods according to interlace scanning is selected. In interlace scanning, based on the end of a blackout state of a scanning line in a field, selection of a scanning line in the next field for writing is started. Writing on a scanning line comprises a reset step of resetting the liquid crystal, a selection step of selecting the final state of the liquid crystal, an evolution step of stabling the liquid crystal into the selected state, and one of the length of the reset step and the total length of the selection step and the evolution step is n times (n: natural number) the other. For example, when the length of the reset step is n times the total length of the selection step and the evolution step and when a frame is divided into m fields (m: natural number larger than n) for interlace scanning, there is a moment when, in serial m scanning lines, n scanning lines of them are in the reset step, one of them is in the selection step or in the evolution step, and the other m-n-1 scanning lines are in a display step.

A display device which has a liquid crystal display having a liquid crystal material, a driver for driving the liquid crystal display, and a controller for controlling the driver to drive at least a part of the liquid crystal display by selectively using one of a first drive method and a second drive method which are different from each other in operational principle of the liquid crystal material. The pulse voltage to drive at least one pixel of the liquid crystal display can be selectively set to any one of a plurality of kinds. The data pulse voltage applied to a data electrode can be selectively set to any one of a plurality of kinds to drive at least one pixel of the liquid crystal.

Liquid crystal display device and driving method thereof

An information display device which is structured as an electronic book with liquid crystal displays which display information stored in a storage medium. The information display device further has a first driving section which drives the liquid crystal displays and a second driving section which drives the recording medium, and while the displays are reset, the second driving section is inhibited from driving the storage medium. Also, the information display device has a speaker, and when a mode to display information on the liquid crystal displays at a high speed is selected, the speaker is inhibited from reproducing sound.

Information display device and information display method

An information display apparatus which has a liquid crystal display which uses chiral nematic liquid crystal with a memory effect and can be driven by a matrix driving method. The screen of the display is divided along a scanning line into a still picture display area and a motion picture display area. The information display apparatus may have a first display and a second display on one screen. The first display is a reflective type liquid crystal display with a memory effect, which has an advantage of saving energy, and is used exclusively to display a still picture. The second display is a liquid crystal display which requires only a short time for writing. Information to be written in a short time, such as inputted information, is displayed on the second display.
