Abstract: A preserving performance of a display state of a display having a ferroelectric liquid crystal (FLC) as a display device is effectively used, thereby realizing a long life of the display. For this purpose, access monitor device is provided. The access of a video memory by display data supply device is monitored. When there is no access for a predetermined time or more, that is, when there is no change in the present display content, display drive control device controls display driving device so as to stop the driving of an FLC panel.

Abstract: Display drive of a ferroelectric liquid crystal (FLC) display device is controlled in accordance with temperature and the number of lines to be displayed and updated. An interlace or non-interlace mode for driving the display device is selected on the basis of the number of scanning lines to be updated and/or the temperature. A table is provided for changing the interlace mode on the basis of various conditions.

Abstract: A display control apparatus and method initializes the display when the power is switched off. The display control apparatus includes a storing unit which corresponds to a display panel and stores display data, a display control unit for achieving an image on the display panel in accordance with the data stored in the storing unit, a detecting unit for detecting disconnection of a power source, and an initializing unit for initializing the storing unit when the detecting unit has determined that the power source is disconnected. The display control method performs display by using information stored in a memory corresponding to the display panel. The method is carried out by detecting a request for power disconnection, writing initialization data into the memory, achieving an image on the display panel by using the initialization data written in the memory, and disconnecting the power.

Abstract: A display controller includes a memory for storing data to be displayed on a display, a unit for supplying data to the memory, a first flag group for indicating a line on the display screen of the display corresponding to data supplied by the data supplying unit, a second flag group for indicating a plurality of the first flag groups, a detector for detecting the status of the display, a selector for selecting the first or second flag in accordance with the status of the display detected by the detector, and a display control unit for reading data designated by the first or second flag selected by the selector from the memory, and displaying the data on the display.

Abstract: A coating apparatus for coating an object with a coating material in a coating direction includes a holder adapted to be mounted on a controllable support member, a shaft slidably supported in the holder, and a head member mounted on the shaft for angular movement in a direction transverse to the coating direction, the head member having a sliding surface for slidable contact with the object and a coating material outlet positioned forwardly of the sliding surface in the coating direction. In another embodiment, the head member has sliding legs for sliding contact with the object at front and rear positions in the coating direction, at least one of the sliding legs having a recess defined therein to provide a gap between the sliding leg and the object, the gap having a prescribed width in a direction transverse to the coating direction.
