Abstract

PURPOSE:To enable discrimination between an abnormal level and a normal level at a glance by a display color, by using a multicolor light emitting element as a display element and by making the display color different between a case when the abnormal level is displayed and a case when the normal level is displayed. CONSTITUTION:A multicolor light emitting element is used as a display element and a display color is made different between a case when an abnormal level is displayed and a case when a normal level is displayed. Concretely, a display control circuit 1 controls the display of the multicolor light emitting element 2 on the basis of an output signal of a level setting circuit 4. A signal for indication display is inputted to an input circuit 5 according to an input signal 6. Based on the inputted signal, an A/D conversion circuit 3 outputs an output value being proportional to the input. In the bar graph display, for instance, a display 11 when the value is a lower-limit set value or below in relation to the input signal 6 or a display 13 when it is an upper- limit set value or above are colored with red or orange to show abnormality. A display 12 in the case when the value is above the lower-limit set value and below the upper- limit set value is colored with green to show normality. According to this constitution, discrimination between the abnormal level and the normal level can be made at a glance on the basis of the display color.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an indicator, a display device, etc. that indicates and displays various input signals.

[Conventional technology]

Conventionally, the light emitting elements used in indicators and indicators are:
When a monochromatic light emitting element was used and did not emit light, a pen type or ribbon type was used to monitor the measured values.

3 and 4 respectively show a block diagram of a conventional instruction display system and an example of instruction display for explaining the operation, including an input circuit 5 which inputs an input signal 6, a level setting circuit 4. A
D conversion circuit 3 and monochromatic light emitting element 7 for displaying instructions
It was composed of. Display when the input signal is below the lower limit set value 21. Both the case 23 where the value is above the upper limit set value and the display where the value is between the lower limit set value and the upper limit set value are displayed in a single color.

[Problem to be solved by the invention]

The above-mentioned conventional indicators and indicators that use monochromatic light emitting elements only display instructions using monochromatic light emitting light in response to input signals, and the display color does not change even if the upper and lower limit levels are set, and there is no visible abnormality. The drawback is that it is not clear whether the level is normal or not.

[Means to solve the problem]

The indication display method of the present invention is characterized in that a multicolor light emitting element is used as a display element, and the display color is different when an abnormal level is displayed and when a normal level is displayed.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. Second
The figure is an example of an instruction display for explaining the operation. The display control circuit 1 controls the display of the multicolor light emitting element 2 based on the output signal of the level setting circuit 4.

A signal for displaying an instruction is input to the input circuit 5 by an input signal 6. The input signal is output by the A/D conversion circuit 3 to an output value proportional to the input.

FIG. 2 shows an example of an instruction display, and this example shows an example of a bar graph display. The display 11 when the input signal is below the lower limit set value and the display 13 when the input signal is above the upper limit set value are displayed in red or orange as an abnormality. In addition, the display 12 in the case where the value is equal to or higher than the lower limit set value and lower than the upper limit set value is an example in which the display is displayed in green as normal.

In the example of FIG. 2, a bar graph display method (analog change display) is explained, but the present invention is a numerical display method (analog change display).
It can also be used for digital change display).

〔Effect of the invention〕

As explained above, the present invention utilizes multicolor light emitting elements as display elements in indicators, indicators, etc.
The display color has the effect of allowing you to understand at a glance whether the level is abnormal or normal.
