Description

Sheet-type display panel with light emitting function {THE DISPLAY PANEL WITH LUMINOUS FUNCTION}

The present invention relates to a sheet-type display panel that is configured in a thin sheet shape to be attached freely and has its own light emitting function, and does not require additional lighting. More specifically, a predetermined guide word or other advertisement, promotional design, etc. The light emitting sheet cut to the same size as the printing contents to emit light on the back side of the transparent cover sheet printed on the printed contents is attached to the printing contents, and a predetermined metal conductor such as wire or FPC (Flexible Printed Circuit) is attached to the printing sheet. In order to connect the inverter for supplying power through the thin-film substrate, it is possible to transform it into a curved surface or various free shapes as needed, and to make it possible to emit light in a continuous or flashing state by selecting only a desired part. Excellent security and ultra thin and light weight It is easy to select the installation place and wide range because it can be applied as a structure, and it is very strong against vibration and shock, and it is easy to maintain and use as long as it is easy to maintain and use. Since it is a non-heating structure, no heat is generated during operation, so there is no need for free space for heat generation, and there is no risk of leakage or fire due to overheating and it does not contain environmental pollutants to have an environment-friendly structure.

The display structure for various promotional guides or advertisements, which are installed in the existing jade, inside and outside, and has a lighting function to give a use effect at night, is usually attached to a box-shaped frame by attaching neon tubes bent to desired contents. An external power source is attached to the inside of the frame to attach a cover of a sheet made of transparent synthetic resin material on which the display contents are printed on the surface or the inner surface of the neon sign or the box-shaped frame and give the lighting effect to the cover at night. It is known that a general structure having a separate lighting structure consisting of applied fluorescent light bulbs or light bulbs.

However, the above structures are structurally impossible to deform the display surface and can only be made flat, and it is impossible to select and emit only the desired parts, so that it is impossible to deform the display structure into various forms, and it is insufficient to secure eyes and use effect. ,

In the latter structure, the illuminance is proportional to the positional proximity of the lighting structure, that is, the illuminance of the entire cover is partially uneven due to the reason that the lighting structure is relatively brighter than the far side. In addition, due to the structure and the lighting structure accommodated inside, the overall thickness increases and the weight also increases, making it difficult to select the installation place and the application place is limited, so that there is a problem that the application is not extensive.

In addition, due to the large weight, waste of time and manpower is required for installation, maintenance and maintenance. As it is a prefabricated structure, it is weak to vibration or shock, causing partial deformation or breakage, and sometimes there is a risk of an accident that the binding part is damaged and falls to the ground. Caused,

In addition, it is a structure that protrudes from the installation surface, and there are many connection parts between the members, so that moisture proofing and waterproofing are not easy, so there are frequent breakdowns and shortened service life.

Due to the large power consumption, it is uneconomical and generates a lot of heat due to the nature of the lighting structure, which implies the risk of fire.Its shortening of the service life of the lighting structure leads to the trouble of maintenance through frequent replacement, In order to have a heat dissipation structure or to have natural heat dissipation through the space, a space for heat dissipation is required to be spaced apart by a predetermined distance from the installation surface, resulting in a complicated structure and excessive occupied space.

In addition, fluorescent lamps and neon tubes contain environmental pollutants, such as mercury, there is a problem that the use of refrain from use is required.

The present invention is made to solve and solve the problems caused by the existing display structure as described above,

The object of the present invention is to be freely deformed and to be able to select only the desired area to emit light, it is excellent in eye-catching and can be applied in an ultra-thin and ultra-light structure, the installation location is easy and extensive selection In addition, it is very strong against vibration and shock, and it is easy to maintain and have long life, and it is economical because of low power consumption. There is no risk of leakage or fire due to overheating and it does not contain environmental pollutants and provides an eco-friendly display panel.

In order to achieve the above object, the present invention provides a light-emitting sheet cut to the same size as the print contents to emit light on the back side of the transparent cover sheet printed with a predetermined guide text or other advertisement, promotional design, etc. Attached to the printed contents and connected to the light emitting sheet with a predetermined metal conductor, that is, an inverter for supplying power through a thin film substrate such as an electric wire or a flexible printed circuit (FPC),

In addition, the inverter 31 converts a small DC power source into an alternating current (AC), and includes a power amplifying element therein to transform the power supply to a voltage required for the display panel. Provide an AC power source with a frequency that does not cause the flicker of light.

In addition, by applying a switching element that operates like a relay to generate a pulse of a predetermined time width, it is possible to obtain a lighting effect that blinks at regular intervals, that is, repeatedly blinks, instead of continuous light emission.

In addition, a switch 44 is provided to turn on / off the DC power supply 42 of the controller 40 to enable power saving when the display panel 1 is not used as necessary.

The cover sheet 10 is made of a transparent synthetic resin material to facilitate deformation, and the light emitting sheet 20 is connected to the controller 40 by a predetermined metal conductor 41 to receive power.
