Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The method of controlling the light emission of an advertising signboard using a plurality of EL panels according to the present invention and the product of the advertising signboard equipped with the light emission control method have a plurality of EL panel pieces provided on the same substrate. Regarding an advertising signboard, when each of the EL panel pieces is efficiently blinked, a current backflow prevention element is used to cause only a specific EL panel piece to emit light, so that only the specific EL panel piece is used. As a result of energizing, leakage is prevented, and the minimum necessary current is turned on. Only the required surface of multiple EL panel pieces is turned on by applying the minimum required current only to the display surface such as the letters of the advertisement. In addition to making it possible to efficiently and sharply blink, save electricity, prolong the life of the EL panel, and also make it possible to blink a color EL panel piece of a specific color. It is.

2. Description of the Related Art A diode used as a backflow prevention element as a means for preventing blurring of a liquid crystal screen due to electric leakage,
Transistors are known. Due to the nature of the liquid crystal material, there is a limit to the size of the liquid crystal screen for displaying on the liquid crystal screen. Therefore, it must be said that it is not practical to use the liquid crystal for an advertising signboard requiring a wide display screen.

The dynamic drive (time division drive) of the EL panel will be described with reference to FIG. 4. EL1, EL2, EL3 are all EL panel pieces, and X1 and X2 are both switches. , Y1, Y2 are all switches. The feature is that the number of wires is small and the number of switches is small. For example, a specific E
When lighting the L panel piece EL1, the switch X2 is connected and the switch Y1 is connected. In this case, EL
1 is turned on, but the EL panel pieces EL2, EL3, and EL4 are also turned on at the same time although they are slightly darker than EL1.

The dynamic drive will be described with reference to FIG. 5. In order to light a specific EL panel piece EL1 at a certain place, the switch X1 must be connected and the switch Y1 must be connected. If you make this connection, E
Only L1 should light up, but EL2, EL3, E
L4 is a little dark, but it will be lit at the same time.

By dynamic drive, EL2, E
The reason why L3 and EL4 are turned on will be described with reference to FIGS. 6 and 7. FIG. 6 shows, by arrows, the directions of complicated currents flowing in the circuit when X1 is connected and Y1 is connected. Since there are EL1, EL2, EL3, and EL4 in the directions of these currents, the respective EL panel pieces are turned on. Each lighting is illustrated by the diagonal lines. Comparing the brightness of the respective EL panel pieces, EL1 that is lit by the X1 connection and Y1 connection is bright, and EL2, EL3, and EL4 that are lit simultaneously with the EL1 are slightly dark. Why does such a difference in brightness occur? FIG. 7 is an electric circuit for easily explaining the cause of the difference in the brightness of the light emission of the EL panel piece due to the dynamic drive. That is, 100 for EL1
Since the voltage of the volt is applied, it lights up brightly, while the same voltage of 100 volt is connected in series with EL2, E.
It can be reasonably understood that this is because L3 and EL4 are also slightly darkened because a voltage of 1/3 is applied to each.

In an advertising signboard using a plurality of EL panels, when the EL panels, which are the illuminants of the advertising signboard, are provided on the substrate, these are arranged in order as the EL panel pieces, and the electrodes of each EL panel piece are provided. By providing a backflow prevention element in the EL panel, a specific E out of a plurality of EL panel pieces is
The L panel piece can be made to emit light. In particular, illuminating all of the advertising billboards with a large area does not achieve sufficient power saving effect in terms of the economics of advertising, and therefore, illuminates only the advertising spots within the wide screen of the advertising billboards. It is indispensable to make certain areas of the advertisement that need to emit light easily and clearly. In order to make only the specific advertisement part emit light, it is achieved by energizing only the electrode of the EL panel piece in that part. For that purpose, it is necessary to enable the use of a backflow prevention element in this advertising signboard so that only the specific advertisement part emits light and the advertisement is not blurred due to the electric leakage due to the current backflow prevention effect of this technology. I am trying. In order to save power, extend the life of the advertisement, display the advertisement clearly, move the advertisement, and color the advertisement, it must be possible to sequentially emit light from a specific advertisement portion of the plurality of EL panel pieces. For that purpose, it becomes possible by putting into practice the prevention of the backflow of the electric current that flows through each EL panel piece of the advertising signboard using a plurality of EL panels, and the specific EL panel piece of the plurality of EL panel pieces The technology of emitting light is an indispensable technology in advertising billboards.

A method of controlling the light emission of an advertising signboard using a panel and an advertising signboard product equipped with the control method are provided in a circuit for providing a plurality of EL panel pieces on the same substrate and energizing a backflow prevention element to an electrode of the EL panel. Electricity is supplied through a current backflow prevention element provided in an electric circuit for energizing the electrodes of the built-in EL panel piece, and only a specific EL panel piece in a certain place is made to emit light, and the specific EL panel piece to be made to emit light is intensively energized. Then, the backflow prevention element is used so that the EL panel piece other than the specific place is not leaked. The light emission control method is such that only a specific EL panel piece is made to emit light by electrically controlling the conduction or backflow to the electrodes of the EL panel with a diode or a transistor, and the leakage of the electrodes to the other EL panel pieces is prevented. Light emission control characterized in that a backflow prevention element is configured in a circuit for energizing electrodes of a plurality of EL panel pieces so that the advertisement is turned on with a clear advertisement by the light emission of the specific EL panel piece. It is a product of an advertising signboard provided with the method and the light emission control method thereof.

An advertising signboard using a plurality of EL panel pieces as specific color EL panel pieces is a red EL in which a red filter is applied to a blue picture EL panel, a green EL panel and a white EL panel by utilizing the three primary colors of light. An EL panel bundle in which the panels are bundled in three colors is prepared, a plurality of EL panel bundles are provided on the substrate, and a circuit for energizing the electrodes is configured.
By thus combining the EL panel bundle of three colors and controlling the light emission by combining the respective colors, it is intended to express the advertisement in color.

[0010]

When the backflow prevention element is placed in front of the electrode of the EL panel piece, the current passing therethrough flows only to one side due to the backflow prevention effect, so that only the EL panel piece desired to emit light can be turned on. Since the current flowing in the opposite direction is stopped, leakage does not occur, so that the EL panel piece whose leakage has been blocked by the backflow prevention element does not light up. Therefore, the EL panel piece located in a place where it is not necessary to emit light as an advertisement is not turned on. As a result, since only the specific EL panel piece that is desired to emit light is turned on, the EL panel piece does not turn on in a place where light emission is unnecessary, the advertising billboard becomes economical, power saving, and the life of the EL panel piece is reduced. Has the effect of stretching. Specific EL panel piece that lights up and EL that does not light up
Since the border with the panel piece can be clearly seen,
Since the advertisement part displayed by the specific EL panel piece emits light clearly and the other parts do not emit light, the outline of the advertisement is not blurred and the advertisement can be clearly discerned from a distance. Therefore, since the EL panel piece provided on the board of the advertising sign can be turned on or off by electronic control, it becomes easy to express characters, figures, symbols, and numbers on the advertising sign, and There is no need to create a separate dial or design panel. Therefore, by using the backflow prevention element in an advertising signboard of a plurality of EL panels, it can be used not only as a moving advertising signboard but also as a clock face dial in which the number indicating the time changes moment by moment. Is.
