Abstract

PURPOSE: To make readable for the display of time to the utmost, by using the entire panel for only time display and adopting two stored display for the data display at the same time, in the unit having clock function and data display function.
CONSTITUTION: In the dot matric liquid crystal display unit, in case of normal time display, signal is fed by regarding the transversal and longitudinal electrodes as one electrode and display is made by using the entire panel. When data write-in and readout signal are inputted. since the data is also displayed, the drive signal for the transversal electrode is decreased to 1/2 level, and the memory content is fed by selecting it to uni-direction to the longitudinal electrode, allowing to display the data and time display in two stages. In this case, the time display can be made in second display at a vacant space.
