JPS60248027A - Method for displaying reception frequency and reception frequency display device in order to execute said method - Google Patents

Abstract

PURPOSE:To obtain a simple reception frequency display method at low cost by using a 1-digit digital display deivce to display a reception frequency in time series. CONSTITUTION:One digit is adopted for a display device 1 for a reception frequency for such as car radio set and the frequency is displayed one by one digit in time series. In applying static drive, 7 segments are enough, current consumption is less, then a display driver 3, a PLL and a control circuit 2 are incorporated in a control IC. In using two-color LED for the display device 1, when an odd-numbered order is displayed in red and an even-numbered order is displayed in green for example, the section of two numerals is made clear to shorten the display time interval between numerals. After the confirmation frequency, when one of a memory button 8 and a channel button 5 is depressed and a desired station of the channel is stored and the display is switched into a channel number at the same time. When the frequency is desired to be confirmed again and the button 8 is depressed, the frequency is displayed temporarily in time series and the display restores to the channel number after a prescribed time again.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is a method to demonstrate the change of Tsukudatsuki's changes and that method to make a real JM'''. Regarding.

n-pupil H view] Conventionally, one station's IM vThTh display [4 digits or 5
This will be abbreviated as a digital display or a light emitting diode (hereinafter referred to as L E I in this specification). ) were lined up in large numbers, and a linear scale chart was used. The former has the disadvantage of increasing the cost of one display due to the large number of 2 digits, and the drawback of this is that it requires a large number of wirings and becomes a core body if the number of digits is large. Because it is an analog device, it has drawbacks such as inaccurate ML wave number table display.

As an example of the former, a configuration as shown in FIG. 4 can be considered. In the figure, 1 is the display device, 2 is the display driver, 3 is the PLL and control circuit, and 4 is the operation unit.However, such a device requires a relatively large amount of current. In the case of display, etc. - Even if a display driver is included in the PLL and control LC, the power consumption will increase, making it a national problem to realize this.

Also, dynamic drive has an impact on Meteor's S/N, so if you use static drive.

There is a drawback that it requires long wiring for the segment, and that it is connected to the first female.

[Purpose of the invention]

Therefore, the purpose of the present invention is to reduce the cost increase and reduce the cost by 7x.
It is possible to provide a wave θ display power that does not require reception.

Another non-invention. ; r: reception (reception that can be implemented and cost reduction 711') is also the purpose of the wave number table.

[Guramei's ML information]

In order to achieve the above-mentioned purpose of delay generation, the reception frequency f according to the present invention is
The 5-display force method uses a 1-digit tezotal display in chronological order to indicate 7J': JruC and missing women. In the receiving frequency edge indicator according to the +J and IJ disaster aspects of the present invention, each segment of the one-digit digital indicator is composed of multiple segments that are not shown in the time series. At the same time, it also serves as a sister to the operation section.

Hereinafter, several songs of the present invention will be made in more detail using the example, without referring to t2J, but they will be summarized as follows.
It goes without saying that there are various modifications and improvements to TxL that go beyond the scope of the present invention.

[Ui-(Su' no Mi BiIIII)] Figure 1 shows the front view of the display device of the car radio according to the present invention.

Even if you use static drive, use a 7-segment tree (.

Since γ1 power consumption tk is low, 1 display driver 3 PLL
In figure 1, PL
The control circuit 2 and the driver 3 are shown in Figure 7.

According to the present invention, if you are trying to tune to a 1134 kHz station, you can use manual tuning! 7. −
is determined by auto-tuning, but Shusaka fl is not included. O) Confirmation is performed using a chronological display such as l, l, 3゜4, without using a single digit. The appropriate time interval for the 70th table is 0.5 seconds between each number, and 1 second between the lowest 1 and the first 1 of the first digit. be.

When using two colors of shi 1], face 1 of odd numbers.

This is the break between the two JI'tl IXM ld...], and in this case the two 1. ! d The number of drums is 4 times 1 m J interval longer than the others (I don't feel safe doing that).

After the frequency 1i'htJl, press the memory button 8 and the channel button 5 to select the ;C channel) i is Me, l; is 2. At the same time, 1 display (1 channel) changes to L/sign.

After the channel is memorized, only channel number 5 and channel number 1 are turned on by pressing channel button 5.

If the frequency is k and old, press the memory button 8 and temporarily set it to JIS 1 as mentioned above! Me is chronologically clothed, and after an hour it returns to the channel flea issue.

If you select a channel manually or by auto-tuning, the 1 time series Shusaka Kin table will disappear after - time, or channel A/tentacles other than company name or 7 like A and P will be displayed.
It may also be represented by a segment.

318th! ! , I is the first diagram of a car radio with a frequency i display (1i11) by Mr. Ya of another implementation of Book 94, and the reference names common to Figure 1 in 1 are those in Figure 1. The channel button 5 is a 7-segment figure-8 tc6etk3, and the display 1 is the same as the display 1.
Kaoru is tied up. With this type of construction, the sheath display can be made larger, which not only makes it easier to see, but also makes it easier to see (LEI) and other display devices.

The illumination system for the display device makes me feel uneasy, and I can press the button without fail even at night. [Effect of the invention] As explained above, one display device can be used as one display device.
In addition to reducing the cost of the device itself, it is possible to reduce the cost of the device itself, since it is possible to reduce the current consumption even when performing static linear motion (therefore, the PLL and control ICK table r MX FE in the dry pan can be reduced). In addition,
7. Since the steering wheel is easy to drive, there are few friends to the audio thread. In addition, the table 1 ruler can be made into a large size, and particularly in the case of a car radio, there is an advantage that the visibility is the same as above.
