Description

[Brief explanation of drawings]

Figures 1a and b are wiring diagrams for explaining the principle of the digital display device according to the present invention, Figures 2 and 3 are illustrations of the display operation of Figure 1, and Figure 4 is an example of an implementation of the present invention. A connection diagram showing an example, Section 5 is an explanatory diagram of the display operation of the embodiment of FIG. 4,
FIG. 6 is a connection diagram showing another embodiment of the present invention. LED,...LEDn...Light emitting diode, A2, A3. A4. A12...Differential amplifier. Amendment October 5, 1982 The scope of claims for utility model registration is amended as follows. O Utility model registration claim entry = In a display device that turns on the indicator at the level -, selectively when the input signal is at the level -, 'I (*''' is at the level). a plurality of display elements,
The input signal is at one of the reference display levels.
At the level of item 1--, which includes a lighting means for causing the lighting F to turn off, and a lighting means for turning off the display element at an adjacent lower level at an intermediate level of the reference display level corresponding to the level at which this lighting F is turned on.
When the 1st hydrogen element is lit, the 1st 8th and 6th rubel lights up at the next higher level, and together with the display element of this higher level, the 1st 8th tongue is lit. As the level of the input signal increases so as to light up 1 hydrogen at the upper level of 2fMn, 1 2
Let's light up the hydrogen on 1 2' ・
A digital display device characterized by the following.

Claims (1)

[Scope of utility model registration request] a plurality of reference voltages corresponding to a plurality of reference display levels of an analog input signal and for comparison with the analog input signal; a plurality of differential amplifiers receiving the analog input signal at one end and receiving the reference voltages at the other end; a plurality of display elements each connected to an output terminal of the differential amplifier so as to light up in response to an input signal corresponding to an intermediate level of a reference voltage, and the differential amplifiers are adjacent to each other corresponding to the reference display level; by regulating the output of the lower level amplifier by the output of the upper level amplifier in cooperation with the analog input signal and the level of the reference voltage, so that the input signal corresponding to the level of the reference voltage has a lower level of the adjacent lower level. The display element is turned off and the display element at the adjacent upper level is allowed to remain lit, and when the input signal corresponds to the intermediate level of the reference voltage, the display element at the adjacent upper level and the display element at the adjacent lower level are turned off. The display elements are connected so as to be lit, each of the display elements is lit one by one in correspondence with the reference display level of the analog input signal, and the intermediate level of the reference display level corresponds to the adjacent reference display level. What is claimed is: 1. A digital display device characterized in that two display elements are turned on at the same time.
