DESCRIPTION JPH06338743
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
equalizer display, and more particularly to an improvement of a display system for facilitating
checking of segment breakage of its display segment.
[0002]
2. Description of the Related Art For example, as shown in FIG. 4, an equalizer display device has
a plurality of display segments Segment-1 to Segment-13 for each of the bands 1K to 500K (Grid
1 to Grid 18). At the time of manufacturing such an equalizer display device, a mode has been
adopted in which the segment breakage of the display segment is checked. In the display
segment check process in this mode, for example, when the power of the equalizer is turned on,
the display segments of the lowermost (Segment-13) of the 16K band (Grid9, Grid18) are
sequentially lighted upward and the 16K band is After all the display segments have been turned
on, the display segments after the next 8K band are similarly turned on sequentially, and then all
the display segments are turned off.
[0003]
However, according to such a conventional check processing method, there is a drawback that it
takes time to light all the display segments. SUMMARY OF THE INVENTION It is an object of the

present invention to provide a lighting method that enables easy check processing of display
segments of an equalizer display device in a short time.
[0004]
In order to achieve the above object, the equalizer display device of the present invention
comprises display means having a plurality of display segments for each band of the equalizer
device, and full band when the equalizer device is turned on. And control means for controlling
the display means to simultaneously turn on the display segments from the lower one at the
same time. In this case, the control means may have a function of lighting the display segment
from when the power is turned on to when the signal is input to the equalizer device.
[0005]
In the equalizer display device according to the present invention, when the power is turned on,
the display segments of the whole band are sequentially lighted sequentially from the lower ones,
so the display segment check processing is easily performed in a short time.
[0006]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present
invention shown in the drawings will be described below.
FIG. 1 shows one embodiment of the equalizer display device according to the present invention,
wherein 1 is an equalizer unit, 2 is a control unit, 3 is an amplifier, 4 is a display unit, 5 is a key
input unit, 6 is a power supply unit, 7 is a power switch, 8 is a power source detection unit.
[0007]
When the power is turned on by turning on the power switch 7, the power of the circuits such as
the equalizer unit 1 is turned on, and after stabilization, the control unit 2 transmits data to the
equalizer unit 1 etc. During a predetermined time until the signal input to 1 is performed, the
display segment of the display unit 4 is checked in accordance with the steps shown in FIG.

First, in step 2a of FIG. 2, the rise of the power is determined, and if the power is not supplied
(NO), the CPU of the control unit 2 is stopped in step 2k, but if the power is raised (YES), the step
At 2b, the internal peripheral circuit power supply is turned on to wait for stabilization, and when
it is determined at step 2j that it is stable, the process proceeds to step 2d.
In step 2d, simultaneous lighting data of the display segments of the lowermost column
(Segment-13) of the entire band of the display unit 4 is transmitted to the display unit 4 as
shown in 3a of FIG. Thereafter, it is determined in step 2e that the predetermined time has
elapsed, and if NO, it is determined in step 2h whether or not the display segment 4a of the
uppermost row (Segment-1) of all the bands of the display unit 4 is lit. If it exists, simultaneous
lighting data of the display segment of one upper row in the entire band is transmitted in all the
bands in step 2f, and the process returns to step 2e, and in this way, 1 in the upper direction
sequentially as shown in 3b and 3c of FIG. The display segments of all bands are lit at the same
time in a row. When the lighting is completed in step 2h or a predetermined time has elapsed,
the normal display is entered in step 2i. In addition, the time to full lighting can also be shortened
more by adjusting the predetermined time of step 2 e.
[0009]
As described above, according to the present invention, since the display segments of the entire
band of the equalizer display device are sequentially lighted sequentially from the lowest one
when the power is turned on, control defects and defects of segment patterns can be made at the
time of manufacture. It can be easily confirmed in a short time.
