Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic bulletin board, and more particularly to an electronic bulletin board that displays characters and the like by a scroll method.

[0002]

[Prior art]

 A conventional electronic bulletin board will be described with reference to FIG. First, the structure will be described. In the electronic bulletin board 50, a large number of lamps, light-emitting diodes 52 and other light-emitting diodes 52 are arranged in a plurality of rows at a predetermined pitch S in the scroll direction (arrow A) and are arranged at right angles to the scroll direction. It has a structure in which a plurality of rows are arranged at a predetermined pitch T in the direction (arrow B). Further, it has a control unit (not shown) for turning on / off each of the light emitters 52. The light emitting colors of the light emitters 52 are the same.

Next, the operation will be described. The control unit drives the light-emitting body 52 to turn on / off based on the input display data such as characters, and displays the characters on the electronic bulletin board in a stopped state ( Fixed display). In addition, the display position of characters and the like is moved in the scroll direction at a predetermined speed to display the entire input predetermined text, figure, etc. on the electronic bulletin board (scroll display).

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional electronic bulletin board has the following problems. The conventional electronic bulletin board has a structure in which a large number of luminous bodies of the electronic bulletin board are arranged in a matrix in the column direction and the row direction at equal pitches, so that the number of luminous bodies arranged is large and the manufacturing cost is low. There is a problem that the power consumption for display also increases as it rises. Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide an electronic bulletin board with low manufacturing cost and low power consumption for display.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has the following configuration. That is, in the electronic bulletin board in which a large number of luminous bodies are arranged in a plurality of columns at a predetermined pitch in the scroll direction and a plurality of rows are arranged at a predetermined pitch in a direction perpendicular to the scroll direction, one column or row is provided. Is characterized in that it is arranged at a position offset by ½ pitch with respect to the column direction or the row direction with respect to the other adjacent column or row.

It is preferable that the luminous colors of the respective columns are the same, and columns having at least red, green, and blue emission colors are repeatedly arranged in a predetermined order.

[0007]

[Action]

 When displaying characters etc. by scrolling method, characters etc. can be displayed without deteriorating the display quality. In addition, if the luminous colors of the respective columns are the same and the columns having at least red, green, and blue luminous colors are repeatedly arranged in a predetermined order, eight-color display can be performed.

[0008]

【Example】

 Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an explanatory view showing an arrangement of light emitters of an embodiment of the electronic bulletin board according to the present invention. First, the structure will be described with reference to FIG. In the electronic bulletin board 10, a large number of lamps, light-emitting elements 12 such as light-emitting diodes are arranged in a plurality of rows at a predetermined pitch S in the scroll direction (arrow A), and in the direction perpendicular to the scroll direction (arrow B). A plurality of rows are arranged at a predetermined pitch 2T, and the light-emitting bodies 12 that form one column (for example, K-row) form another adjacent row (for example, L-row). The structure is arranged at a position deviated from the arrow B) by the T pitch. In addition, it has a control unit (not shown) for turning on and off each light emitting body 12. Note that the light emitting colors of the light emitting bodies 12 are the same. With this structure, the number of the light emitting bodies 12 arranged on the electronic bulletin board 10 is half the number of the conventional examples described above.

Further, the control unit defines therein a microcomputer (not shown), a RAM (not shown) for storing display data such as display characters and graphic data inputted from the outside, and an operation of the microcomputer. ROM (not shown) in which data for storing is stored, a shift register (not shown) that receives display data sequentially output from the microcomputer and moves the display data in the scroll direction at a predetermined speed, and a shift register And a driver circuit (not shown) for turning on / off a predetermined light emitter based on the data of the shift register.

Next, the operation will be described. The control unit drives the light emitter 12 to turn on / off based on the input display data such as characters, and the characters are displayed on the electronic bulletin board at a predetermined speed in the scroll direction. Move to and display the entire input text, figure, etc. on the electronic bulletin board. In this case, if the displayed characters and the like are displayed while being stopped at a specific position, the number of the light emitters 12 is halved, so the edges of the characters and figures are not displayed smoothly, but the characters and the like are always scrolled. In the case of display, the afterimage effect of human eyes enables display with a character quality that is almost the same as the conventional scroll display. Further, in the arrangement of the light emitters in FIG. 1, the arrow A direction and the arrow B direction are the same array, so the scroll direction may be the arrow B direction.

In addition, the luminous colors of the respective columns are the same, and columns having at least red, green, and blue emission colors are repeatedly arranged in a predetermined order (for example, column K is red, If the L row is green and the M row is blue), when scrolling in the direction of arrow A at an appropriate speed, red, green, and blue that are lit due to the afterimage effect of human eyes are mixed, and all colors It is possible to display eight colors in total, including black when is turned off. Further, when performing multi-color display as described above, the number of light emitters may be half, so that even if a three-color light emitting type, which has a high unit price, is used for the light emitters, an increase in the product cost of the electronic bulletin board can be suppressed. You can

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and any control unit having the above-described function can be used. It goes without saying that many modifications can be made without departing from the spirit of the invention, such as the circuit configuration.

[0013]

[Effect of device]

 When the electronic bulletin board according to the present invention is used, even if the number of light emitters is reduced by half, in the case of scroll display, there is almost no deterioration in the quality of displayed characters and graphics. Therefore, the manufacturing cost can be reduced and the power consumption for display can be reduced. In addition, if the luminous colors of the light emitting elements forming each row are the same and at least the rows having at least red, green, and blue light emitting colors are repeatedly arranged in a predetermined order, 8-color display can be achieved. Play.
