Sign board using flexible EL-sheet

The present invention relates to a billboard using a flexible electroluminescent sheet, more specifically, to catch the attention of consumers at night as well as at night by using a flexible electroluminescent sheet (aka neon flex) of self-luminescence, the thickness of the billboard Thinner and lighter weight make it easier to install on the glass and wall of the store, as well as on the ceiling, and the ad text can be easily replaced with the printed paper or PET film. In addition, it relates to a billboard using a flexible electroluminescent sheet that can be installed on curved surfaces and the like by designing the ad text directly without the help of a professional.

In general, the billboard is to provide the information the advertiser wants to catch the attention of the consumer. Therefore, it attracts the attention of consumers by expressing unique characters, figures and colors. Conventionally, the letters or figures desired to be written or engraved on the acrylic sheet or synthetic resin sheet are often used, but since the visibility is greatly reduced at night, recently, neon lamps, fluorescent lamps, CCFL (Cold Cathode Fluorescent Lamp), etc. It's common to use the backlight to make your ad visible at night.

1 shows an example of a billboard 100 using a fluorescent lamp generally used in the prior art, as shown in the figure, a plurality of fluorescent lamps 104 are installed at predetermined intervals in an aluminum frame 102 of a predetermined shape, and An acrylic plate or advertising synthetic resin fabric (aka flex; 106) is attached to the front surface, and the desired characters or figures are printed or attached to the surface thereof. However, the billboard 100 using such a fluorescent lamp is inevitably thick because of the use of a bulky glass tube type lighting lamp, and has a problem that the weight is heavy due to the fixing device for attaching the fluorescent lamp. In addition, conventional fluorescent lamps are fragile and inflexible, not only susceptible to external impact, but also are not surface-treated, and there is a problem in that environmental pollutants such as mercury are generated during disposal.

On the other hand, in recent years, a self-luminous electroluminescent sheet (EL) has been developed. The electroluminescent device forms a light emitting layer by sequentially forming a fluorescent layer and an insulating layer between the transparent conductive film and the back electrode to form a light emitting layer and to protect the light emitting sheet. To the surface light-emitting body consisting of a structure in which a protective film is inserted between the insulating layer and the back electrode, the light generated in the fluorescent layer is emitted through the transparent conductive film when an alternating voltage is applied to the light emitting layer. The electroluminescent sheet is an ultra-thin plane of 2 mm or less and has an operating frequency of 400 Hz to 2,000 Hz at an operating temperature of -35 to 70 ° C.

In addition, the present applicant has developed a new flexible electroluminescent sheet (aka Neon Flex; Application No. 10-2002-27074) that can be manufactured in a large area by adding flexibility to the conventional electroluminescent sheet. By using the light emitting device, it was designed to be a billboard using a flexible electroluminescent sheet that is not only thin, light, and has environmental resistance, but also freely and largely curved.

In addition, the present invention incorporates a microprocessor capable of program control in an inverter used to emit a self-emitting flexible electroluminescent sheet, thereby enabling various display effects such as multichannel operation, dimming, and on / off repetition. It is to provide a billboard using a flexible electroluminescent sheet that can grab the attention of consumers.

In order to achieve the above object, the billboard using the flexible electroluminescent sheet according to the present invention includes a flexible electroluminescent sheet having a predetermined size having an electrode for receiving power and a predetermined size for supporting a rear surface of the flexible electroluminescent sheet. And a back support plate of and an inverter for supplying predetermined AC power through the electrode.
