Image Number 4 for United States Patent #4970502.
A dot matrix type liquid crystal display panel is used with a central processor unit for displaying a message longer than the capacity of the display panel. The beginning portion of the message of a length equal to the capacity of the display panel is first displayed at one time and held on the display panel for a limited length of time facilitating the viewers' recognition of the meaning of the message. When the repeated display of the message is desired, the display state where the end of the message is in alignment with the last digit position of the display panel is held for a given length of time. The first and final holdings of the message results in enhancing legibility of the display contents on the panel.
