Display device of measuring device

Abstract

Abstract PURPOSE:To simplify circuit constitution and wiring, by providing a graphic display part due to dot matrix display and a character display part due to segment display in the same picture. CONSTITUTION:The detection output of the thermistor 12 provided to a thermometer probe 4 is supplied to CPU 6 through an A/D converter 5 and the driving circuit 7 of a display apparatus 1 is operated on the basis of said detection output by CPU 6. The display device 1 of this apparatus is constituted by providing a graphic display part 10 showing the change in measuring temp. graphically by dot matrix display and a character display part 11 showing the measuring temp. as a numerical value in matching relation to the graph of the display part by segment display in the same picture 1a. As mentioned above, by setting the display part 11 to the segment display system, the circuit constitution and wiring of the display part 11 can be simplified and the size of the display part 11 can be planned freely without being affected by the dot pitch of display part 10.
