The following describes the operation of the multi-color light-emitting digital indicator of the present invention having the configuration as described above.

5 is a pulse train configuration diagram for implementing various colors in the multi-color light-emitting bar digital indicator according to an embodiment of the present invention.

First, the operation of setting the data display color will be described.

After the data display color setting mode key 211 of the color setting mode input unit 210 is pressed, key values of the color input keys 221 and 222 are input so that a desired color is displayed on the multicolor bar display unit 160.

That is, the desired color can be displayed by pressing the down key 221a and up key 221b of the color input key 221 and the down key 222a and up key 222b of the color input key 222.

For example, the pulse train shown in FIG. 5A is a case where both the first LED R and the second LED G set as default values when there is no key input are driven at the same time. In this case, In the multi-color bar display unit 160, yellow, which is a 1: 1 mixture of red and green, is displayed.

In the case of the pulse train illustrated in FIG. 5B, the down key 222a of the color input key 222 is pressed once. In this case, the first LED R is normally driven but the second LED G is Since the on-pulse duration is reduced by ?? T1, the mixing ratio of red and green is less than 1: 1 and the mixing ratio of green is reduced to be displayed in orange in the multicolor bar display unit 160.

In the case of the pulse train shown in FIG. 5C, when the down key 221a of the color input key 221 is pressed twice to reduce the red mixing ratio, in this case, the second LED G is normal.

The LED emission signal is output to display the height corresponding to the data value measured by the multi-color bar display unit 160.

At the same time, the data display color determination unit 320 reads the data display color stored in the color storage unit 170 under the control of the controller 310 to determine the color to be displayed, and then displays the data display pulse width adjusting unit 330. )

The data display pulse width adjusting unit 330 is based on the color data received from the data display color determination unit 320, for example, in the case of the light green color of FIG. 5C, the 'on pulse of the second LED (G) 'On pulse duration time' of the first LED (G) without adjusting the 'on pulse duration control signal' having a pulse train reduced by ?? T2 to the LED driver 150.

The LED driver 150 operates the second LED G normally based on the 'on pulse duration control signal' and operates the first LED R by reducing the on pulse duration by ?? T2. LED color driving control signals' are output to the plurality of first LEDs R and second LEDs G, respectively.

The user is displayed in light green color by mixing light emitted from the first LED R and the second LED G operating by the LED color driving control signal received from the LED driver 150.

On the other hand, when the value measured from the sensor is within the set alarm range (that is, the abnormal data), the control unit 310 outputs an alarm mode signal to the alarm color determination unit 340, the alarm from the control unit 310 After receiving the mode signal, the alarm color judging unit 340 reads the alarm color stored in the color storage unit 170 under the control of the controller 310, determines the color to be displayed, and then alarms the pulse. Output to the width adjustment unit 350.

The alarm pulse width control unit 350 is based on the alarm color signal received from the alarm color determination unit 340, for example, in the case of the orange of FIG. 5 (b), 'on pulse duration of the first LED (R). 'ON pulse duration time' of the second LED (G) does not adjust the 'ON pulse duration time control control signal' having a pulse train reduced by ?? T1 to the LED driver 150.

The LED driver 150 operates the first LED R normally based on the 'on pulse duration control signal' and reduces the 'on pulse duration' of the second LED G by ?? T1. 'LED color drive control signal' for outputting to the plurality of first LED (R) and the second LED (G), respectively.

An alarm color displayed in orange is displayed to the user by mixing light emitted from the first LED R and the second LED G operated by the LED color driving control signal received from the LED driver 150. In addition, even the remote user can see the displayed color and easily know that the alarm mode.

The embodiment of the present invention is just one embodiment of the technical idea of the present invention, and in the person skilled in the art, other modified embodiments are possible within the technical idea of the present invention.

The multi-color light emitting digital indicator of the present invention having the configuration and operation process as described above has the following effects.
