It is relatively lightweight and easy to install on a pillar or wall. It is a flexible display with a thin waterproof function of an EL lamp for the purpose of obtaining various flexible media such as advertisements, signs, and safety signs.

[0003]

2. Description of the Related Art Conventional EL lamps have been used as means for preventing leakage, electric shock, fading of the light emitting surface, etc. from EL lamps.
The surface of the EL element is covered with a transparent flexible resin film for waterproofing, and the conducting wire connected to the contact is provided outside the resin film and provided on the panel surface. In order to further improve the waterproof function, a conductive wire (lead wire) is adhered between the resin films around the contact points with silicon resin to prevent rainwater, outside air, etc. from entering there. The contact point is where the end of the lead wire connected to the blinking controller is to be soldered, and if rainwater or the like enters the contact point, it is the weakest point because electric leakage occurs from here and you get an electric shock. Therefore, by overcoming this weak point and illuminating with an electric light obtained by blinking the EL lamp, the sign, the guidance, the attention, and the advertisement are conspicuously represented by the movement of the electric light, so that the EL lamp that consumes less power is used as a light source. It is necessary to invent an appropriate waterproofing mechanism in order to use it for various purposes and obtain various products such as signs.

[0004]

Technical problems to be solved by the invention
The EL element in the inside is covered with a film made of a resin which is itself waterproof. Since the area around the contact is waterproof with silicone resin, water cannot pass through the lead wire of the lead wire and easily enter the panel, but the water of the lead wire connected to the contact The edge itself is the weakest point because it is directly exposed to air. Because it is always exposed to the outside air, that part becomes the weakest part due to acid rainwater and salt damage of seawater. Therefore, in lighting devices using such EL panels as light sources, It is necessary to waterproof the outside of the panel. In particular, it is an indispensable requirement for a lighting device provided outdoors to be provided with a minimum necessary waterproof mechanism in order to prevent rainwater from entering. If protected by such a purposed waterproofing mechanism, it is possible to prevent leakage of electricity from the EL lamp and prevent discoloration and fading of the design film sheet, and therefore the life of the EL lamp and design film sheet. Will last much longer than if it were not waterproof. Wearing a display both indoors and outdoors, having a thin waterproof mechanism, and having flexibility,
It is necessary to meet the conditions such as being provided on a glass window, a cylinder, a prism, a wall surface, etc. depending on the place of attachment, and being provided on glass, an iron plate, mortar depending on the material of the object to be attached. The present invention was born from such a need, and is an electroluminescent sign using an EL lamp, which is intended to prolong the illumination of an EL having an extremely large area as compared with a light source such as an incandescent lamp, a diode lamp, and a fluorescent lamp. In order to be able to obtain advertising billboards and the like, it is intended to develop a flexible display with a thin waterproof function for EL lamps.

[0005]

[Means for Solving the Problem] In order to solve the technical problem, it is possible to store an EL lamp as a light source of the design film sheet together with the design film sheet for alerting, guidance display, advertising billboards, etc. In the flexible display with thin waterproof function for EL lamps, the transparent and flexible resin sheets on the front and back are combined, and the surroundings are heat-sealed, and a bag section for the EL lamp and film sheet is provided between them, and the entrance Section and the lead wire of the EL lamp are left, and the resin sheet on the front and back is fused to form a fused portion,

It is a flexible display with functions.

[0006]

With such a structure of the present invention, the thin flexible display with waterproof function of the EL lamp according to the present invention can be manufactured to be thin and lightweight as a whole. In addition, the shape can be easily changed by using a flexible resin sheet that can be bent softly. Therefore, in the present invention, the illumination light source is EL
It is easy to attach a sign sheet such as a sign or an advertising signboard to a flat attached object such as a window glass, a door iron plate, a mortar wall, etc. and an attached object with a curved surface such as a cylinder and an attached object with a corner such as a prism, etc. Therefore, the EL lamp has a wide utility value as a waterproofing mechanism for EL lamps in various modified usage forms both indoors and outdoors.

The opening and closing of the point chuck at the entrance of the bag makes it easy to store the EL lamp of the light source and the film sheet such as the sign. Since the replacement of the film sheet is easy, any kind of sign may be used, and the design film sheet can be replaced and used according to the standardized marking plate size. The attachment means corresponds to various shapes and materials at various places of attachment, and any member such as a suction plate, a rubber magnet, a magic fastener, or a double-sided adhesive tape can be selectively used. That is, by selectively executing the mounting means, it is possible to mount the glass door, the gate pillar, the mortar wall, the door iron plate, the cloth wall, the wooden parts, and the like in correspondence with the material shape of the mounted object. The design film sheet has various indications depending on the purpose of use on the film sheet, for example, an arrow indicating a direction, markings such as a beginner's mark, a nameplate, an advertising signboard of a company or a hospital, a call of a radio engineer.
