Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an electronic device that uses a computer to drive a display drive circuit and display electronic news on a display.

It relates to a youth display system.

In recent years, computer control has come to be used also in electronic news display systems. However, the conventional electronic news display system consists of a display 1 and a computer system 2 dedicated to display control, as shown in FIG. Everything from the manual input of the information to the control of the display was carried out exclusively.

In this way, the conventional electronic news display system is expensive because everything from the manual input of the information to be displayed on the display to the control of the display is constructed using a dedicated computer system. When a large number of display devices are installed, each display device requires a dedicated computer system for display control, which significantly increases costs.

When the same information is to be displayed on a large number of displays, the manual work of providing information to each display control computer system is easy and must be done at the location where each display is installed.

Furthermore, such a dedicated display control computer system cannot be used while the display is displaying electronic news, and cannot be used to operate the display while the information to be displayed on the display is being manually operated. This point also contributes to the high cost.

The present invention aims to eliminate these problems and provide an electronic news display system that can efficiently display electronic news using a large number of display devices at a low cost. A system for driving a display driving means to display electronic news on a display, the system comprising an indoor system, at least one outdoor system, and an interface connecting the indoor system and the outdoor system, wherein the indoor system is configured to drive the display. The outdoor system stores the character data signals created by the indoor system and is independent of the indoor system. The said character memorized in the state.

That is, the present invention is configured with a separate indoor system and an outdoor system, thereby making it possible to display electronic news only with the outdoor system, thereby making it possible to use the indoor system without being restricted by the operation of the outdoor system. As a result, it is possible to display electronic news on numerous outdoor systems by character data signals indicating the information to be displayed on a display produced by one indoor system, and in particular to facilitate the use of general-purpose personal computers for indoor system computers. This made it possible to achieve the intended purpose.

Examples will be described below.

generate. Note that the controller 18 also generates a mechanism control signal in response to the generation of this head drive signal. In this embodiment, the head drive signal, which is a character data signal output from the controller 18, is taken out, amplified by the transfer circuit 14, and transmitted outdoors. Sent to System 4.

Figure 4 shows the data drive system of the transfer circuit.

Note that, when the distance between the indoor system having the remote control system 6 and the outdoor system 4 is long, it is desirable to adopt a current loose drive method using a photocoupler.

The outdoor system 4 receives the character data signal sent from the transfer circuit 14 of the indoor system 3 by the I10 port of the microcomputer forming the display controller 13. FIG. 5 is a timing chart of signal transmission and reception between the transfer circuit 14 and the display controller 13, and shows a, d, e, b,

16 signals, an interrupt request signal, and an interrupt request enable signal.

FIG. 6 shows the configuration of the display 1 of this embodiment, and FIG. 7 shows an example of the display. The number of dots is 16 in the column direction and 160 in the row direction, and one character consists of 32 bytes. It is now displayed.

In FIG. 6, the rows and interest rates are indicated by X and Y, respectively. FIG. 8 is a memory map showing how the character data displayed on these displays 1 is stored in the memory section of the microcomputer of the display controller 13. Stored as byte data.

FIG. 9 shows the details of the display drive circuit 12 for character data stored in the microcomputer of the display controller 13, in which the signals in the dot column are Y1 to Y□6, and the signals in the dot row are X1 to X1. It is X160. This figure shows an example in which the character "two" is displayed by a dot with a circle. Figure 10 shows a timing chart of the signal when the character [2] is displayed.The pulse width and period are determined by appropriate values depending on the lighting conditions of the display section, but the dot row signal Y is determined by the number of dot rows. Determined by The twisted dot row signal X is a signal corresponding to character data, but its pulse width is matched to the Y signal.

Note that t1 to t16 indicate the pulse width of each dot row constituting one character, T1 indicates the time required to form one dot row, and T2 indicates the time and money required to form 16 dot rows constituting one character. .

Figure 11 shows the relationship between character data set time and character lighting time. For example, if the lighting time of a light bulb is 35 mS,
In other words, if the characters are shifted by one line every 35 m5, 10 m5 is the data set time by the computer, and the remaining 25 m5 is the actual lighting time, but visually it looks like 35 m5 of light bulbs are lit. In other words, the character data set time also appears to be lit.

In this electronic news display system, the personal computer system 6 inputs information to be displayed on the display 1 of the outdoor system 4 and outputs character data signals. First, input is performed using a software such as a word processor, and the manually inputted character data is displayed on the display 10 for confirmation and then recorded on the printer 9. Output by a printer is performed using character data signals rather than character codes.

This character data signal is input to the transfer circuit 14, and transferred from the transfer circuit 14 to the display controller 13 of the outdoor system 4. The display controller 13 receives this character data signal at the I10 port of the microcomputer (7) and stores it.

Note that the outdoor system 4 side outputs a READY signal indicating a state in which display signals can be received as a status signal, and an interrupt enable signal as a response signal to the character data interrupt request signal from the indoor system. Then, on the indoor system 3 side, the data and song 16 are used as character data signals.
It outputs signals and interrupt request signals necessary for unscheduled display of temporary news and the like.

After the display controller 13 of the outdoor system 4 receives the character data signal from the indoor system 3, only the outdoor system can display the lightning news. It can be operated completely independently, regardless of the display.

Therefore, a personal computer can be used, for example, to manage customers requesting lightning news commercials, create quotations, etc., so a single personal computer can provide a comprehensive system for displaying lightning news. It is possible to reduce costs.

In addition, in this electronic news display system, the microcomputer used for the display controller of the outdoor system only needs to be capable of storing and controlling;
For example, an indoor computer system can be used to display kanji characters, and this computer system only needs to be used when creating documents, so there is no need to use a dedicated computer that can perform all of the functions of storage, control, and document creation.

In addition to regularly displaying news, weather forecasts, announcements, and events, such electronic news also includes occasional interruptions such as breaking news, high school baseball, and election news. Editing can be done on the indoor system without regard to the outdoor system, and the memory contents of the outdoor system's display controller can be replaced in the completed state.In other words, document creation can be done separately from the lightning news display. , display contents can be changed flexibly, and can be displayed easily and quickly.

Further, since documents can be created using the general-purpose pancon system le, handling is easy.

FIGS. 12 and 13 show other different embodiments, which are used when the outdoor system is far away from the place where news, commercials, etc. are created. In these figures, the same parts as in FIG. 3 are given the same reference numerals.

In these figures, 21 is a display controller, 22 is a display monitor, 23 is a data recorder on the indoor system 3 side,
24 indicates a data file, 25 indicates a data recorder on the outdoor system 4 side, 26.27Fi indicates an acoustic coupler on the indoor system 3 side and the outdoor system 4 side, respectively, and the display controller 21, display monitor 22, and data of the indoor system 3, respectively. The recorder 23 and data file 24 or acoustic coupler 26 and the data recorder 25 or acoustic coupler 27 of the outdoor system 4 constitute an interface between the indoor system 3 and the outdoor system 4.

In the embodiment shown in FIG. 12, the information to be displayed on the display 1 is converted into a character data signal by the personal computer system 6, and this character data signal is directly received by the display controller 21, stored in the memory section of its microcomputer, and displayed. After confirming the stored contents on the monitor 22, the data recorder 23 records the data file 2, such as a cassette tape for recording.
Record in 4. The data file 24 in which this character data is recorded is taken to the outdoor system 4, that is, the location where the electronic news display l is installed, and the data recorder 25 is used to read out the contents of the data file 24 and the microcomputer of the display controller 13 reads out the data file 24 using the data recorder 25. Store it in the memory section. The character data stored in the display controller 13 is displayed as electronic news on the display 1 by the display drive circuit 12.

The electronic news display system of this embodiment can obtain the same effects as the embodiment of FIG. 2, but this embodiment also eliminates the need for special wiring between the indoor system 3 and the outdoor system 4. , and the character data created by the PC system 6 in the indoor system 3 is stored in one data file 24 in the display controller 1 of the plurality of outdoor systems.
Alternatively, a plurality of data files 24 can be created by the data recorder 23 of the indoor system 3 and stored in the display controller 13 of each of the plurality of outdoor systems 4.

That is, in an electronic news display system having a plurality of outdoor systems 4, the method of this embodiment has particularly significant effects in terms of handling and economy compared to the embodiment of FIG.

The embodiment shown in FIG. 13 uses acoustic couplers 26 and 27 in place of the data recorders 23 and 25 of the embodiment shown in FIG. It is designed to be transferred to System 4. This embodiment provides the same effect as the embodiment shown in FIG. 12, but in this case, the character data stored in the display controller 21 can be transferred to the outdoor system 4 using the acoustic coupler 26 and the telephone line. Therefore, data such as news, commercials, etc. created can be transferred to the electronic news display of the outdoor system more quickly than in the embodiment shown in FIG.

As described above, the present invention makes it possible to provide an electronic news display system that allows electronic news to be displayed efficiently and at low cost using a large number of display devices, and has great industrial effects.
