Description

Detailed Description of the Invention [Technical Field] The present invention is a bar display device, which has a plurality of 1J adjacent bar display elements, and which changes the display target by sequentially lighting up the bar display elements in a fixed direction. The present invention relates to an improvement of a bar display device capable of displaying integrated values and other display parts in analog form.

Furthermore, the present invention relates to a bar display device in which the analog display scale is displayed in an easy-to-read format.

[Prior art] It is necessary to display measured values of various amounts of change in all industrial fields, and various display devices have been put into practical use. When it comes to displaying vehicle speed, total distance, etc., time, etc., there is a need for display devices that do not require great precision and are rather easy to read. .

A bar display device is known as a device suitable for such a display object, in which a plurality of adjacent bar display elements are arranged in a line and are sequentially illuminated in a fixed direction according to the measured value of the front thread object. For example, it allows relatively rough readings even for measured values that change very quickly, making it extremely suitable for the demands of daily life.

However, in the analog display device of this scale,
It is necessary to display separated values as a scale for displayed values.
Various structures have been proposed for this purpose. For example, Utility Model Application No. 55-112287 and Utility Model Application No. 55-133386
The number is provided with a numeric display element for the scale, separate from the bar display group that displays the actual measured values. However, such conventional devices have the disadvantage that the shape of the display element is complicated, making it difficult to manufacture, and the effective display area is reduced because a space is required for displaying the scale.

As other conventional devices, Utility Model Application No. 57-39392 and Utility Model Application No. 57-39393 are known, and in these devices, a selected bar display element f is selected from among general bar display elements. It does not show a configuration in which it is used as a division display for the scale. Although this device can increase the overall display area efficiency by 1, it still requires a specially designed division display element for the scale, for example, and a complete display for other divisions. (There was a problem that it could not be put to practical use.

As yet another conventional device, a configuration has been proposed in which scale numerical elements are printed on a cover glass that covers the surface of these display elements separately from the bar display elements, but in this device, the bar display elements and printing It is troublesome to align the scale with the scale, and there is often a problem that the display function is deteriorated due to misalignment between the two.

[Object 1] of Invention E The present invention has been made in view of the above-mentioned conventional problem, and its purpose is to use a bar display element as a division display element for a scale when displaying measured values of a display target in an analog manner. -4- It is an object of the present invention to provide an improved bar display device which is completely sharable and does not require special delimiter display elements.

According to the present invention, the structure of the display section can be extremely simplified by sharing the bar display element and the partition display element, and the display space efficiency can be increased, so that the area can be expanded or the device can be made smaller. It has the advantage of not degrading the reading of the displayed value in any way.

Therefore, the bar display device of the present invention is extremely useful as various small devices, such as various vehicle display devices installed in a limited vehicle interior, an hour display device, and the like.

[Structure of the Invention] In order to achieve the above object, the present invention provides a display unit having a plurality of adjacent bar display elements, a display control circuit that sequentially lights up each of the bar display elements in a predetermined order, and a display target. a display signal generator that provides a predetermined display signal to the display control circuit in response to a change in the display control circuit; a delimiter setter that selects a delimiter display element from the plurality of bar display elements; and a delimiter display element selected by the delimiter setter. a division lighting signal generating circuit which supplies a signal to the display control circuit to light up the bar in advance; a delimiter light-off signal generation circuit that supplies the display control circuit;
The selected division display element is lit in advance, and when the actual display passes the division display element, the division display element is turned on and the U division position is displayed in reverse.

[Description of Embodiment] First Embodiment FIG. 1 shows a display example in the first embodiment of the bar display according to the present invention, in which a plurality of bar display elements 10-1 to 10-1 are shown.
10-25 are arranged in a line adjacent to each other. The bar display element group 10 in the embodiment is each composed of a liquid crystal display element, and by lighting up each element in order from the left, it is possible to display a predetermined measured value of the display object in an easy-to-understand manner for the user.

FIG. 1(A) shows three bar display elements 10-1 to 1 from the left.
0-3 is displayed, indicating the display value [-3]. In such a display state, the characteristic feature of the present invention is that a divided display is performed at a predetermined selected scale interval, and furthermore, this divided display is shared with the bar display element described above. be. That is, in the example, the scale interval is set for every "5" of the display value, and in the figure, the scale interval is 10-5.10-10.10-15.10-2.
Each bar display element of 0.10-25 is used as a delimiter display element and is pre-illuminated, so that the user is always aware of the scale position of the display.

However, on the other hand, this common use of the bar display element and the division display element has the disadvantage that when the actual display overlaps or overtakes the division display element, which is always lit, it becomes impossible to display the scale. In the present invention, in order to eliminate this drawback, when the actual display exceeds the delimiter display, the delimiter display element that has been lit until now is turned off, as shown in FIG. The feature is that the delimiting position is indicated by an inverted (negative) display such as J: which is clear from the figure.

Therefore, even when displaying the display value "61" as shown in FIG. It is possible.

Furthermore, this embodiment is characterized in that when the actual display overlaps with any of the delimiter displays, the delimiter display element blinks at a stage immediately before the overlap in order to identify the two.

That is, FIG. 1(B) shows the display value "4", and FIG. 1(C) shows the display value "5", and in either case, the bar display elements 10-4 and 10-5 Since both are controlled by lighting, there is a drawback that the image display values cannot be identified. Therefore, in this embodiment, as shown in FIG. 1(B), the corresponding separator display element 10-5 is blinked immediately before the actual display overlaps with the separator display, and as shown in FIG. 1(C). It is distinguished from the state of

-8- Therefore, according to this embodiment, the user can easily read the actual displayed value even when the two overlap.

FIG. 2 shows a schematic circuit of a first preferred embodiment of the present invention for obtaining the display form of FIG. 1 described above.

The bar display elements 10 made of liquid crystal or the like are arranged in a line in a display section 12 provided to suit a desired display object. Provided in the display device to be incorporated.

A display control circuit 14 is provided for controlling each bar display element 10 of the display section 12 to turn on or off,
The display of each bar display element 10 is sequentially controlled in a predetermined order based on a predetermined vehicle speed signal. As is well known, a driver 15 for driving the liquid crystal is provided between the display control circuit 14 and the display section 12.

The display control circuit 14 is supplied with a display signal φ2 indicating a measured value corresponding to a change in the display target from a display signal generator 16. For example, the display signal generator 16 may include a vehicle axle rotation speed detector or the like. A pulse signal corresponding to the vehicle speed is output as a display signal φ2.

Furthermore, in this embodiment, the bar display element 10 is repeatedly displayed at a high frequency that cannot be discerned by the user, and for this purpose, in FIG. 2, a reference signal generator 18 and a counter 20 are provided. The reference signal generator 18 outputs a clock pulse φ1 having a frequency of 2501-lz or more as a base i-low signal to the counter 20.
This clock pulse controls the repetitive lighting action of each bar display element 10, and synchronizes each part.

A characteristic feature of the present invention is that in order to obtain the first display form described above, a predetermined selected bar display element is used as a delimiter display element, and for this purpose a delimiter display circuit 22 is provided. This delimiter display circuit 22 includes a decoder 24.

The delimiter display circuit 22 includes a delimiter that sets a desired element from the plurality of bar display elements 10 as a delimiter display element, and in the embodiment, a delimiter display element is selected for every display value 1-51.

Further, the delimiter display circuit 22 includes a delimiter lighting signal generating circuit for lighting the selected delimiter display element, and in the embodiment, the delimiter lighting signal B from the decoder 24 is supplied to the display control circuit 14.

Further, the delimiter display circuit 22 includes a delimiter turn-off signal generation circuit for performing the inverted display shown in FIG. 1, and outputs a delimiter turn-off signal A to the display control circuit 14.

The operation shown in FIG. 2 described above will be schematically explained based on FIG. 3.

In the embodiment, the clock pulse φ1 has a relatively high frequency of 2501-1z, and this clock pulse φ1 is sequentially counted in the counter 20, outputs a counter output Q corresponding to the number of bar display elements 10, and is sent to the display control circuit. 1
4 sends the display control signal F to the driver 1 based on this output Q.
Output to 5.

-11- The display signal φ2 acts as a reset signal in the circuit configuration of this embodiment, and as is clear from FIG. 3, when the display signal φ2 is supplied to the display control circuit 14, the display control signals F are all reset. Ru.

On the other hand, since the delimiter lighting signal B is supplied from the delimiter display circuit 22 to the display control circuit 14, the control signal F5 is output immediately after the reset by the display signal φ2, and
: Then, the bar display element 10-5 of the display section 12 is illuminated as a delimiter display element. Of course, as is clear from FIG. 1, the lighting of each bar display element at every division interval of "5-1" is controlled in the same way, but the explanation of these other division display elements will be omitted below.

The display signal φ2 also resets the counter 20, and therefore, the counter output Q and the display control signal F described above are sequentially output like the output of the display signal φ2, until the display v3 III signal F-F7. It is understood that the bar display elements 10-1 to 10-7 sequentially light up and display in response to the sequential signals.

-12- Separate control as shown in FIG. 1 is performed on the selected division display element 10-5, which will be described in detail later.

In the embodiment, when up to "7" is displayed, the display signal φ2 is again supplied to the display control circuit 14, thereby resetting each display control signal F described above, and the above operation is repeated again. Therefore, in the embodiment, the displayed value can only reach a maximum of 17'', and by repeating this at a relatively high frequency, the user can continuously see that the current displayed value is ``7''. can be recognized. In fact, in the embodiment, the repetition period of the display signal φ2 is 32 milliseconds, and it is almost impossible for the user to discern this repetition period.

It is understood that the display signal φ2 from the display signal generator 16 changes its generation cycle in accordance with changes in the display target, and this change changes the maximum display value, so that it performs a predetermined display action. .

Although the general operation of the first embodiment is clear from the above description, the delimiter display circuit 22 and the τ display control circuit 14 in this embodiment will be explained in detail next.

FIG. 4 shows a specific circuit configuration of the delimiter display circuit 22, including a delimiter setter 26, a delimiter lighting signal generation circuit 28, and a delimiter display circuit 22.
, a division light-off signal generation circuit 30, and a reset circuit 32.

In the embodiment, the delimiter setter 26 is composed of a group of externally operable changeover switches, and can arbitrarily select a desired bar display element 10 as a delimiter display element.

In FIG. 4, the four changeover switches output the binary signal G "ololJ", which means that the delimiter interval [51] is set.

Then, the section 1.13 setting signal G set in this way is supplied to the section lighting signal generation circuit 28, and the AND gate group outputs the signal @E to the decoder 24 in synchronization with the display signal φ2 or the switch switching signal. Then, the decoder 24 converts this incoming advance signal E into a decimal signal and a delimiter lighting signal B at 1).
Convert and output.

Therefore, in the embodiment, since the delimiter interval is set to "5" in the delimiter setter, the decoder 24 of the delimiter lighting signal generation circuit 28 outputs the delimiter interval [B5'B10-B15'' set in increments of 51. It is understood that a delimiter lighting signal of ' is output.

The above-described division light-off signal generation circuit 30 synchronizes the output G of the division setter 26 with the clock pulse φ1, and turns the division light off when a predetermined display value, that is, the actual display exceeds the selected division display. In the embodiment, when "6." is displayed, a delimiter light-off signal A is output.

FIG. 5 shows a time chart illustrating the operation of the division extinguishing signal generation circuit 30.

The clock pulse φ1 is divided by a frequency division counter 34, its output is compared with the delimiter setting signal G by a group of exclusive NOR gates, and its output J is passed through an AND gate 36 and converted into a signal by a flip 70 tube (hereinafter referred to as FF). 38. Since the clock pulse φ1 is supplied to the reset input of FF3B, it is understood that the division light-off signal A is output at the display timing of the display value "6". That is, the frequency division counter 34 is reset to the display signal φ2 through the OR gate 40 at the initial stage of the star mill, and this
・Due to the timing, after performing the operation determined by the arithmetic circuit and the delimiter setting signal G while counting one pulse φ1, the delimiter light-off signal A mentioned above is output, as shown in FIG. , at the display value [6-1, the predetermined section 1, TlfJ light signal @A will be output.

As mentioned above, in this embodiment, if J:, the delimiter setter 26
includes a group of switches that can be operated externally, and can arbitrarily change the division interval, but when changing the division interval, a reset signal is supplied to the AND gate group of the division lighting signal generation circuit 28, and for this reason, the above-mentioned The reset circuit 32 calculates changes in the delimiter setting signal G using an OR gate 42.

That is, each delimiter setting signal G is supplied as it is or after being inverted by an inverter (V) to the one-shot 1~ circuit, and these one-shot signals W are supplied to the A-Agate 42 described above, and as a result, If even one of the -16- delimiter setter QG changes, the reset circuit 32
The reset signal C will be output from.

In Fig. 6, the delimiter setting signal is shown in the delimiter interval "10" to "151".
As is clear from the figure, each time the selector switch is operated, the reset I/circuit 3
2 outputs a reset signal C, which is sent to the delay circuit 4.
4 (x), is output as a gate signal Y from the OR gate 46 to the AND gate group of the delimiter lighting signal generation circuit 28, and the delimiter setting signal G is read and signal converted at each changeover switch operation timing. Of course, the display signal φ is sent to the OR gate 46 via a delay circuit 48.
2 is supplied (7), and the delimiter setting signal G is read and converted every time the display signal φ2 is output.

Next, the display control circuit 14 in this embodiment will be explained to WWIA based on the specific circuit configuration of FIG. 7 and the flowchart of FIG. 8.

This display control circuit 14 includes control circuits 50-1 to 50-n provided for each bar display element 10, and corresponds to the control circuit 50-1 corresponding to the lowest bar display element 10-1 and the highest bar display element 10-n. Each control circuit 50-n has a unique circuit configuration, but the remaining control circuits 50-2 that belong to the middle
~50- (-n) all have the same circuit configuration,
In FIG. 7, three intermediate control circuits 50-4 to 50-6 are shown corresponding to the bar display element 10-5 selected as a delimiter display element and two bar display elements before and after this. ing.

In order to output the display control signal F in the control circuit 50-5, each control circuit 50 has two FF5s.
2.54, the first FF 52 is used for delimited display, and the second FF 54 is used for actual display.

That is, the delimiter display FF52 mainly uses the delimiter display signal 1.
4B, and the display FF 54 is set by the counter output Q.

A agate 56 is used for the reset input of the FF52 for dividing display.
The counter output Q and the output of the OR gate 58 are supplied from the gate, and the outputs of the AND gate 60 and the OR gate 62 are supplied to the input of the OR gate 58. The input of the OR gate 62 is supplied with the reset I to signal C and the display signal φ2. Furthermore, the input of the AND gate 60 receives the delimiter lighting signal A and the counter output Q from the adjacent upper position.

The output P of the delimiter display FF 52 is supplied to two AND gates 62 and 64, and further outputted as a display control signal F via an OR gate 66. and gate 6
The other input of 2 is a display signal FF from an adjacent lower position.
The output is supplied inverted. Further, the display FF output from the adjacent lower position and the blinking signal φ3 from the reference signal generator 18 mentioned above are supplied to other inputs of the FF 64.
In the embodiment, this blinking signal φ3 has a frequency of 11-1z. Furthermore, the output of the AND gate 64 and the output of the display FF 54 described above are supplied to other inputs of the OR game 1-66.

On the other hand, the output N of the aforementioned OR gate 58 is supplied to the reset input of the display FF 54, and the output R of the -19-FF 54 is supplied to a group of AND gates in adjacent upper positions.

As described above, to the control circuit 50-2 belonging to the middle, 5O
-(n-1) has a similar configuration, and has a chain connection of the counter output Q and the output of the display FF 54 between successively adjacent circuits.

On the other hand, the control circuit 50-1 at the lowest position has the same circuit configuration as the circuit at the intermediate position described above, except that the blinking AND game 64 is removed and the input signal from the adjacent upper level is removed. .

Further, the control circuit 50-n located at the highest level has the same circuit configuration as the control circuit located in the middle except that the connection with the adjacent higher-level circuit is removed.

The operation of the display control circuit 14 will be explained below with reference to the time chart shown in FIG.

By inputting the clear signal C or φ2, both FFs 52 and 54 are reset, and all bar display elements 10 are turned off. However, immediately after this, the delimiter lighting signal B5
is output and the separator display FF52 is set to
The output P5 is supplied to the AND gate 62, and at this time, because the output R4 of the adjacent lower display FF is 1-0 due to the reset, the AND gate 62 outputs the signal S5. As a result, the display control signal F5 is supplied to the bar display element 10-5 via the driver 15, and this element 10-5 is turned on as a delimiter display element.

From this state, the counter output Q of the counter 20 is supplied to the display control circuit 14, and the above-described lighting operation of the bar display element 10 shown in FIG. 3 is sequentially performed. Bar display element 10-4 adjacent to and below the delimiter display element 10-5
In order to turn on the counter output Q4, the control circuit 50-4
When supplied to the set input of the display FF 54, the FF
54 becomes "1", a control signal F4 is outputted via the OR gate 66, and the bar display element 10-4 lights up.

At the same time, the FF output R4 is supplied to both AND gates 62 and 64 of the control circuit 50-5, and the AND gate 62 and 64 are supplied with the FF output R4.
The output S5 is set to 10'', and the gate 64 is opened.

As mentioned above, the AND gate 67I receives the blinking signal φ3.
As a result, the output T of the AND gate 64 depends on the clock signal φ3, and a light-on or light-off signal is output from the OR gate 64 every 0.5 seconds. This state is represented by the signals T and F in FIG.
5 is indicated by the broken line. This lighting state is shown in FIG. 1(B).

Next, when the signal Q5 is output from the counter, the output 05 of the OR gate 56 resets the delimiter display F F 52.
- Therefore, the output P5 becomes "0" and the delimiter display including the blinking effect is turned off. On the other hand, the counter output Q5 changes the display FF 54 to cell 1, and the OR gate 66 is output from the output R5. The control signal is via F5
is turned on and the light is turned on continuously, resulting in the state shown in FIG. 1(C).

Furthermore, when the signal Q6 is output from the counter 20, at this time, the division extinguishing signal generation circuit 30 outputs the division extinguishing signal, so that the characteristic division display according to the present invention is turned off and the division is inverted. A display will be made.

First, the circuit 5 controls the bar display element 10-6 at the adjacent upper position of the delimiter display element using the signal Q6 as described above.
0-6 outputs control signal F6 by display FF54,
As a result, the bar display element 10-6 located above the adjacent bar is lit.

At the same time, this signal Q6 causes the AND gate 60 in the adjacent lower order to output the signal M5 together with the delimiter light-off signal A, thereby resetting the display FF 54, as shown in FIG. 1(D). Performs the function of turning off the delimiter display element. Therefore, according to this embodiment, when the actual display exceeds the delimiter display as shown in FIG. 1, it is possible to turn off the delimiter display and achieve an inverted (negative) display.

Second Embodiment FIG. 9 shows the display form of the second embodiment using the present invention, and the difference from FIG. The purpose of the first embodiment is to simply light the element without blinking, and to blink the separator display when the 1"5" display shown in (C) is displayed. There is a difference between being in the stage immediately before duplication and in the stage of duplication.

FIG. 10 shows a specific circuit of the display control circuit 14 in the second embodiment, which is similar to the circuit configuration in FIG. In the second embodiment, the blinking effect is performed only when the actual display and the delimiter display overlap, so that the chain connection with the adjacent lower display is removed.

Below, the 10th will be explained with reference to timer 1 in FIG. 11.

After the clearing effect is performed by the reset signal C or the display signal φ2, the division display element 10-5 is turned on by the division display signal B5, as in the first embodiment described above.

Then, J: is displayed in sequence on the counter output Q - 24
- When the elements 10 light up in a predetermined order and the signal Q5 is output, the display FF 54 is first set, and its output R5 blocks the output P5 of the delimiter display FF 52;
The signal ■5 based on the blinking signal φ3 is outputted, thereby outputting the blinking control signal F5 to the driver 15. In this embodiment, the blinking signal φ3 is Q, which is the highest output of the counter 20. may also be used.

Therefore, according to this embodiment, when the actual display overlaps with the separator display, the separator display element can be controlled to blink.

When the actual display exceeds the delimiter, the delimiter is turned off as in the first embodiment, and a predetermined inverted display can be obtained.

11 Urako 1 FIG. 12 shows a display form in a third embodiment of the bar display device according to the present invention, and according to this embodiment,
As is clear from FIG. 12(B), when the adjacent lower part of the separator display is used for actual display, the −n separator display is turned off. /I is shown and will be explained below together with the time chart of FIG.

As in the first embodiment, the display control circuit 4 in the third embodiment includes a delimiter display FF 52 and a display FF 54.

Further, according to this embodiment, since the lighting effect of the delimiter display is not required, the outputs of both FFs 52 and 54 are simply
-66. Then, the signal from the adjacent lower order is supplied to the OR gate 56, and the delimiter display FF52
This is done by resetting the .

In FIG. 14, the initial clearing effect and the lighting control of the division display in advance are similar to the embodiment of Haku.

When the adjacent lower part of the delimiter display is lit by the actual display, this signal Q4 is sent from the OR gate 56 to the delimiter display FF5.
Reset 2. Therefore, in this state, the delimiter display element 10-5 is turned off as shown in FIG. 12 (B), and confusion with the actual display can be avoided.

When the actual display overlaps with the separator display, the display FF 54 is set to display as shown in FIG. 12(C), so that the separator display and the actual display can be distinguished without the need for any blinking action. be able to. Similarly to the embodiment of Haku, in the third embodiment, when the actual display exceeds the separator display, the separator display can be turned off as shown in FIG. It is possible.

[Effects of the Invention] As explained above, according to the present invention, some elements selected from ordinary bar display elements are lit in advance as delimiter display elements, thereby making it possible to distinguish between the actual display and the delimiter display. How can it be shared?

Therefore, according to the present invention, it is possible to always display the entire scale as a divided display and obtain an easily readable display.

-27- Further, by sharing the actual display and the partition display according to the present invention, the bar display element can have a normal shape and a large display, and the display space efficiency can be improved or the device can be made smaller. There is.

Furthermore, according to the present invention, there is no need for any other specially provided scale display or scale printing on the cover, etc.
It is human nature to try to simplify the device.
