More specifically, the present invention relates to control of image display by the electronic bulletin board.

[0002]

2. Description of the Related Art Conventionally, an LED (Light Emitting Diode) has been used as an electronic bulletin board which is installed in a place where a large number of people come and go, such as on a street or in a station yard, and electrically displays certain information and advertisements.
Some use. In the case of this LED display, character display is mainly used, and images are limited to simple graphic displays.

[0003]

It is considered that the role played by electronic bulletin boards will increase more and more in the information society in recent years. Further, in a situation where various types of information are overflowing, it is desired that the electronic bulletin board function can provide necessary image information and the like with good timing. On the other hand, PDPs (plasma display panels) have recently been used as display devices.
Is attracting attention. This PDP has features of a large screen, thinness, and light weight, and thus can be said to be suitable for an electronic bulletin board. An object of the present invention is to provide necessary image information and the like with good timing as described above, and to provide an electronic bulletin board using a PDP for a display unit.

A first memory unit in which is written, a second memory unit that stores image data read from the first memory unit, and a display unit that displays based on the image data from the second memory unit. An electronic bulletin board comprising control means for controlling the display data storage unit, the first memory unit, and the second memory unit such that required images are sequentially displayed on the display unit in a required order. Is provided.

Further, the control means includes a control data memory section in which control data relating to a display procedure is stored in advance, and a display data storage section, a first memory section, and a control section based on control data in the control data memory section. And a control unit for controlling the second memory unit.

Further, a timer section for measuring the time is provided under the control section, and controls so as to display required image data in a required time zone.

Further, an operation unit for performing an input operation for designating the control data is provided, and the data relating to the designation is transmitted to the control unit via a transmission line, and the control unit transmits the data based on the control data relating to the designation. Perform necessary control.

Further, the display section may be a display section for driving a plasma display panel based on image data from the second memory section to display an image.

[0009]

Embodiments of the present invention will be described below with reference to the drawings based on embodiments. FIG. 1 is a main part block diagram showing one embodiment of an electronic bulletin board according to the present invention.
In FIG. 1, reference numeral 1 denotes a display data storage unit which stores all types of display image data to be displayed. Reference numeral 2 denotes a first memory unit that stores data sequentially read from the display data storage unit 1 as an image to be displayed next to the currently displayed image. Reference numeral 3 denotes a second memory unit for storing data read from the first memory unit 3. Reference numeral 4 denotes a display unit, and a driving unit 4a
And a PDP (plasma display panel) 4b. A driving unit 4a drives the PDP 4b based on the image data read from the second memory unit 3 to display a required image.

Reference numeral 5 denotes a control data memory unit which previously stores control data indicating the types (contents) of images to be displayed on the display unit 4 and the display order thereof. 6
Is a timer section for measuring time. Reference numeral 7 denotes a control unit, which reads required data from the display data storage unit 1 based on the control data of the control data memory unit 5 and the time data by the timer unit 6, and reads the first memory unit 2 and the second memory unit 2.
And controls writing and reading of each of the memory units 3. An operation unit 8 is connected to the control unit 7 via a transmission line 9 and specifies the control data from a remote place.

Next, the display image data stored in the display data storage unit 1 and the control data of the control data memory unit 5 will be described. The former display image data means all types of image data such as information and advertisements suitable for each layer, such as for students, housewives, or office workers. Information, advertisements, and the like provided by the electronic bulletin board generally have different degrees of interest depending on age, occupation, gender, and the like. In addition, the density of the ethnicity (students, housewives, office workers, etc.) that travels generally differs depending on the time of day on the street where the electronic bulletin board is installed or in the station premises. As described above, in order for the electronic bulletin board to fully exhibit its function, it is necessary to display appropriate information, advertisements, and the like at appropriate times. From this viewpoint, data relating to a display procedure determined in advance is the above-described control data.

For example, when it is assumed that predetermined types (for example, five types) of images for student, housewife, and office worker are prepared as types of display image data, these are used in the operating hours of the electronic bulletin board in one day. Allocate in advance. In other words, images are allocated in advance from office hours to × hours for office workers (five types), from XX hours to XX hours are images for students (five types), and so on. indicate. The time as an element of the control data is measured by the timer unit 6 under the control of the control unit 7, and the control unit 7 performs display control using the time data.

Next, the overall operation will be described. The control unit 7 reads required image data from the display data storage unit 1 based on the above-described control data (control data memory unit 5), and writes the read image data to the first memory unit 2. Further, the control unit 7 reads out the image data from the first memory unit 2 and stores the image data in the second memory unit 3. The second memory unit 3 plays a role as a buffer memory in relation to the display unit 4. The driving unit 4a drives the PDP 4b based on the image data read from the second memory unit 3, and displays an image. Thereafter, necessary image data based on the control data is sequentially read from the display data storage unit 1 and is passed through the first memory unit 2 and the second memory unit 3 to the display unit 4 (PDP 4b).
Is displayed with. Thereby, required image data is sequentially displayed in a required time zone.

Next, remote control will be described. As shown in FIG. 1, the operation unit 8 is connected to the control unit 7 via the transmission line 9. The transmission line 9 is formed by, for example, a LAN (local area network) or RS-232C. The operation unit 8 is, for example, a personal computer (P
C) may be used. With the above configuration, the operation unit 8 transmits a signal (command) specifying control data (control data memory unit 5) to the control unit 7. The control unit 7 reads out image data from the display data storage unit 1 based on the designated control data and causes the display unit 4 to display the image data. As described above, since the signal specifying the control data is transmitted from the operation unit 8, the communication traffic (the exclusive use of the line) can be reduced as compared with the case where the control data is transmitted.

[0015]

As described above, according to the present invention, a necessary image can be displayed on an electronic bulletin board in an appropriate time zone. That is, control is performed so that still images suitable for each layer, such as office workers, students, housewives, and the like, are displayed in appropriate time zones. Thereby, the effect of providing information or advertising as an electronic bulletin board can be further improved. Also, remote control using a transmission line such as a LAN is enabled. In this case, since the signal transmitted from the operation unit is a signal for designating control data, there is an effect that communication traffic (occupation of a line) can be reduced as compared with the case where control data is transmitted.
