摘要:
A display control apparatus for a display apparatus having a display device in which a liquid crystal such as a ferroelectric liquid crystal is used as an operating medium for display-updating and the updated display state can be held by applying an electric field or the like. The display control apparatus comprises a first updating circuit to update the display content of the entire screen of the display apparatus, a second updating circuit to update the display content of a part of the display screen, a detector to detect an external factor such as a temperature of the display apparatus, and a switching circuit to switch the first and second updating circuits in accordance with the detected external factor.

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.

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.

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.

An overtaking prediction method of, when input and output of data to and from a common memory are being performed with an input frame frequency and an output frame frequency made different from each other, predicting a frame in which overtaking occurs between the input and the output of the data to and from the memory. The overtaking prediction method includes a step of predicting the frame in which the overtaking occurs between the input and the output of the data, on the basis of a first parameter corresponding to a difference amount between a progress speed of a write address and a progress speed of a read address and a second parameter corresponding to a difference between a write address and a read address at an overtaking prediction point and to an offset address difference amount between an input offset address and an output offset address.
