Abstract
Description
The present invention relates to a method for efficiently manufacturing a light guide plate of a light emitting diode light emitting unit used in an advertisement signage device.
In general, the advertisement signage device includes a light source installed inside the frame and an advertising film such as a live action film illuminated by the light source.
As a light source of an advertisement signage device widely used in the related art, a fluorescent lamp, a cold cathode fluorescent lamp (CCFL), and the like are used. In addition, fluorescent lamps and CCFLs, which are used as light sources of conventional advertisement signage devices, are all used as direct lighting for directly illuminating the live film from the rear surface of the live film.
Such a light source used in a conventional advertisement signage device has a short lifespan and thus causes color stains due to fading colors when used for a long time, and polluting the environment because fluorescent materials are used. In addition, the conventional advertising signage device has a problem that the thickness is so thick that the relatively large volume and the fluorescent lamp or CCFL used as an illumination source consumes too much power.
Recently, in order to solve the problem of the conventional advertisement signage device, there is a tendency to employ a light distribution unit (BLU) using a light emitting diode (LED) as an illumination source of the advertisement signage device.
As a result, LEDs used in light-emitting units (BLUs) for advertisement signage devices generally adopt a direct type method. However, in the direct type, a large amount of LEDs are used, so productivity is low, it is difficult to match luminance uniformity, and there is a limit in reducing the thickness of the device. Prior to the advertisement signage device, a liquid crystal (LCD) display device employing LEDs as a light distribution source has recently used a so-called edge type BLU having LEDs mounted on the side.
Adoption of LED as a BLU is also rarely used in advertising signage devices. 1 is a cross-sectional view of a conventional advertisement signage device employing LED as an edge type BLU. Referring to FIG. 1, the BLU 2 serves as a light source for illuminating the
The
An object of the present invention is to solve the above problems, to improve the pattern and manufacturing method of the light guide plate used in the BLU of the advertising signboard device and to efficiently provide the light guide plate of various sizes desired by the consumer and at the same time significantly increase the manufacturing cost It is to provide a light guide plate manufacturing method of the light distribution unit for the advertisement signage device lowered.
In order to achieve the above object, a light guide plate manufacturing method of a light distribution unit for an advertisement signage device according to an embodiment of the present invention includes a printing disc preparation step of preparing one printing disc integrally provided with a plurality of light guide plate printing patterns;
A printing step of printing a printing pattern on the light guide plate member using a diffusion ink using the printing original plate;
A drying step of drying a dot pattern formed on one surface of the light guide plate member printed and formed in the printing step; And
And a cutting step of cutting the light guide plate member to the size of each pattern according to the plurality of types of light guide plate printing patterns after the drying step.
The thickness of the light guide plate member is preferably 1mm to 10mm.
The material of the light guide plate member is preferably any one of an acrylic resin, a polycarbonate resin, and glass. However, other materials may be adopted as long as the light transmittance can be used for optical purposes.
The drying method used in the drying step is preferably infrared drying, box oven drying, or ultraviolet drying method.
In order to achieve the above object, a light guide plate manufacturing method of a light distribution unit for an advertisement signage device according to another embodiment of the present invention includes a printing disc preparation step of preparing one printing disc integrally provided with a plurality of light guide plate printing patterns;
A light guide plate preparing step of preparing light guide plate members to match the sizes of the plurality of light guide plate printing patterns;
A printing step of printing a printing pattern on the light guide plate member with a diffusion ink using the printing original plate in a state where the light guide plate members are arranged to match the pattern of the printing plate; And
And a drying step of drying a dot pattern formed on one surface of the light guide plate member formed by printing in the printing step.
The light guide plate manufacturing method of the light distribution unit for an advertisement signage device according to the present invention can efficiently supply a light guide plate having a size that meets the needs of a consumer, as compared with the conventional method of manufacturing a light guide plate that forms a scattering and diffusion pattern by a V-cutting method. In addition, the luminance is improved, the manufacturing cost is reduced, and the productivity of the light guide plate is remarkably improved.
