Hereinafter, with reference to the accompanying drawings for a vehicle billboard using the EL sheet according to the present invention will be described in detail.

1 is a view showing the overall configuration of a billboard for a vehicle using an EL sheet according to the present invention, Figure 2 is an exploded perspective view of a billboard for a vehicle using an EL sheet according to the present invention.

As shown, the vehicle billboard using the EL sheet according to the present invention is electrically connected to the power source of the vehicle and the inverter 10 for converting the EL sheet driving AC wave type AC is electrically connected to the inverter 10 A control unit 30 is provided to control the current applied from one inverter 10 and to adjust the flashing or brightness of the EL sheet 110 and the like. In addition, the EL sheet 110 which emits light by using the current applied by the control unit 30 is attached to the upper side of the EL sheet 110 and projected to a design of a character, a figure, etc. of the corresponding advertisement. Advertisement sheet 120, a barrier layer 132 attached to the upper side of the advertisement sheet 120 to block ultraviolet rays, the third attachment portion 134 and the second attachment to be attached to the inner surface of the vehicle glass It is provided with an advertising bulletin board consisting of a UV blocking sheet 130 is formed.

First, the inverter 10 has a sinusoidal alternating current path in which an EL sheet can drive a direct current applied by connecting one end of the vehicle to a power source (not shown) or a cigar jack (not shown) and the first cable 12. Convert.

The controller 30 is electrically connected to the inverter 10 and is connected to the EL sheet 110 and the second cable 32. On the other hand, the second cable 32 has a predetermined number of cables therein and is individually connected to each part of the EL sheet 110. Each part of the above-mentioned EL sheet 110 refers to a portion where each letter or design of the advertisement sheet is printed, and a portion through which light passes from the EL element 112.

Accordingly, the controller 30 emits the EL element 112 by applying current to each cable of the second cable 32, while controlling the corresponding portion, that is, the EL sheet 110, through the second cable. To adjust the luminance of the EL sheet 110. This allows each part of the EL sheet 110 to emit light in whole or individually, giving a dynamic feeling and enhancing a high advertising effect.
