本考案は一致判定用表示器に係り、特に複数の
信号等の大きさを複数色の多点で表示し、信号等
の大きさの一致、不一致が判読しやすいようにし
た一致判定用表示器に関するものである。[Detailed description of the invention] The present invention relates to a display device for determining coincidence, and in particular displays the sizes of multiple signals, etc. with multiple points in multiple colors, so that it is easy to read whether the sizes of signals, etc. match or do not match. The present invention relates to a display device for determining a match.

整がしにくい。又、複数の表示列は占有面積が広

機器には不都合であつた。 Conventionally, in a display device called a so-called level meter that displays the magnitude of a signal, etc. using multiple points, in order to display the magnitude of a plurality of signals, etc., a plurality of columns of display devices 13 are used as shown in FIG. , 13 were used. However, since this method requires even a small space between columns, it is difficult to see the display and make level adjustment difficult when trying to make the magnitude of a plurality of constantly fluctuating signals (for example, a stereo music signal) the same level. Furthermore, since the plurality of display columns occupies a large area, this is particularly inconvenient for measuring instruments and small devices with many operation knobs.
本案は上記の欠点に鑑みなされたもので、以下
本案を詳細に説明する。 This proposal was developed in view of the above-mentioned shortcomings, and will be explained in detail below.

i (i=1, 2, . . . 7) indicates that the green light emitting diode is lit. Therefore, the display element 1i (i=
1, . . . 4), the diffusion sheet 6 provides a yellow-orange display which is a mixture of red and green. Furthermore, in the display elements 1 5 , 1 6 , 1 7 in which only one of the green light emitting diodes is lit, the entire display element appears to shine green due to the effect of the diffusion sheet 6. Therefore, the coincidence or mismatch of the signal levels becomes obvious at a glance. Incidentally, when the diffusion sheet 6 is not used, the two light emitting diodes 2 and 3 may be molded with resin (not shown). In this case, a milky white resin containing a diffusing agent is also effective.

(commonly known as C-MOS transistor)) By using an absolute value type comparator 11 consisting of an operational amplifier, for example, whose output stage is configured with 10, 10, one comparator can connect a set of light emitting diodes 2, An example of driving 3 is shown. In this case, it is necessary to display the magnitude of the two signals in the chopper mode used in oscilloscopes, etc., but since the wiring of the light emitting diodes 2 and 3 is connected in antiparallel, the number of terminals on the display is limited. It is extremely small and easy to implement.

These are always-on display elements that display in red and green, respectively, and are marked with blank characters (not shown) such as 〓, 〓, etc. as necessary.
This allows the level adjuster to confirm that the power has been turned on, and also to instantly determine which level should be adjusted when one level is high. Also, the wiring of the display device is easy because it can be connected to the two light emitting diodes in series (or in parallel) to one line introduced from the power switch, and then connected to the common line of the light emitting diodes in the other display elements. I can do it.

Since the lighting color of the display element is displayed in a mixed color of the different colors in the portion where the signals and the like match, it is possible to provide a match determination display in which the match of the levels can be read very easily.
