Abstract
PURPOSE: To simplifty the circuit constitution as well as to reduce the occupied area of the display circuit by sharing the memory circuit displaying the numerical data with the display of the decimal point, symbols and others.
CONSTITUTION: Liquid crystal diaplay part 17 performs the necessary display through the combination of the first electrode of 3-division for each digit and 2nd electrode of 3-division common to each digit. In this case, display process circuit 13 obtains the 1st to 3rd display data to select the 1st electrode of display part 17 based on various data delivered from RAM2. In other words, the 1st to 3rd display data obtained at circuit 13 are written into 1st to 3rd memory holding circuit 15 in a time-division way based on the 1st and 2nd input driving signals delivered from driving signal generator circuit 12 to display 17 and numerical data plus decimal point and signal data. In this way, RAM2 to display the numerical data is shared with the display of the decimal point, the symbols or the like, thus simplifying the circuit constitution as well as reducing the occupied area of the display circuit.
