Abstract

PURPOSE: To obtain a light and compact thin type portable book by adding a driving signal for display only when a picture displayed on a ferroelectric liquid crystal display is changed to another picture, and adding no driving signal for display after picture display is rewritten.
CONSTITUTION: The function of a book is attached by reproducing data of one picture from an EPROM card by the operation of an external input key 3 in a reproducing device, displaying it on a display part 2, and reading the display by an operator. At this time, the display of 30 characters by 50 rows is performed in vertical display on the display part 2, then, it is set as one picture. Furthermore, the next picture can be displayed and read by the operation of the input key 3 when it is desired to read it. The picture is changed by adding a liquid crystal display signal on a ferroelectric liquid for two times at every operation of the input key 3 by the operator, and the display of a sentence is performed by utilizing a memory characteristic held by a ferroelectric liquid crystal material without adding the driving signal at a time other than that. In such a way, a portable, light, and compact book can be obtained.
