Description

Detailed Description of the Invention

The present invention relates to an advertising board using a liquid crystal display panel, and more particularly, to an advertising display section having a desired design formed on one or both sides of a liquid crystal display panel on which a polarizing film is not fixed. The present invention relates to an advertising board using a liquid crystal display panel for advertising.

Generally, there are two types of advertising boards, one that uses a lighting means and the other that does not use a lighting means. As a device that does not use the illumination means, there is a device in which an opaque color sheet or a semi-transparent color sheet having a different color from the acrylic panel, which is cut along the pattern, is attached to the surface of the acrylic panel for use. As a type of using the illumination means, a light source is arranged inside a box-type case in which a semitransparent panel such as acrylic is arranged on the front surface, and on the surface of the semitransparent panel arranged on the front surface of the case, There is a color sheet or a semi-transparent color sheet which is different from the color tone of this panel, in which letters, numbers or designs expressing the content for advertising purpose are fixed.

However, an advertising board in which a color sheet is simply fixed on the surface of an acrylic panel cannot be expected to have an advertising effect at night. On the other hand, an advertising board using a lighting means can obtain a certain advertising effect at night by displaying a color sheet fixed on the surface of a signboard by a light source installed inside, but an illumination lamp is used during the daytime. The illuminance is low and it is not possible to obtain a sufficient advertising effect.

Neon signs are also widely used. However, the neon signboard has a low advertising effect during the daytime, which requires a lot of power to operate the neon sign, which imposes a large burden on the maintenance cost. You have to replace the whole thing and it costs as much as a new one, so
There is a problem that there is a limit to changing the advertisement content.

In recent years, an advertising board using an LCD panel has been developed. As shown in FIG. 9, a known liquid crystal display panel 90 is provided with segment electrodes 91 for displaying characters, numbers, etc., and a polarizing plate 92 and a reflecting plate 93 are provided on the back side of the liquid crystal display panel 90. It has a structure in which a polarizing plate 94 having a directivity different from that of the polarizing plate 92 is attached to the front side.

Therefore, when power is applied to the liquid crystal display panel 90, the segment electrodes 91 to which power is applied display characters or numbers by displaying differently from other parts, and a predetermined advertisement is carried out. Will be done.

However, in the case of a conventional advertising board using a liquid crystal display panel, in order to change an advertisement draft such as letters or numbers, it is necessary to replace the segment electrode with a new advertisement draft. However, the segment electrode in the panel cannot be replaced, and a new segment electrode must be designed and manufactured. This is expensive and time consuming. Even if they can be replaced, special segment electrodes cannot be mass-produced, and in reality, they are as expensive as designing and manufacturing new ones.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an advertising board using a liquid crystal display panel, which is inexpensive and in which the advertisement bill and the like can be easily changed. To aim.

Another object of the present invention is to provide an advertising board using a liquid crystal display panel that can obtain an advertising effect not only at night but also during the daytime.

Yet another object of the present invention is to provide an advertising board using a liquid crystal display panel that is lightweight and easy to install and remove.

Still another object of the present invention is to provide an advertising board using a liquid crystal display panel, which can be applied to a conventional advertising board and can further improve the advertising effect.

An advertisement board using a liquid crystal display panel according to the present invention for solving the above-mentioned problems includes at least one liquid crystal display panel having one or more segment electrodes built therein, and at least the liquid crystal display panel. It is characterized by including an advertisement display part formed on one surface.

The segment electrodes may be plate-shaped or may be a plurality of dot-shaped electrodes formed along the front surface of the liquid crystal display panel.

The liquid crystal display panel is preferably partitioned into a plurality of partition parts, and each of the partition parts includes an independent segment electrode. More preferably, the advertisement display section is formed by fixing a polarizing or refracting film on the front surface of the liquid crystal display panel. Alternatively, it may be formed by printing or applying a paint on the front surface of the liquid crystal display panel.

A front polarizing plate may be fixed on the front side of the liquid crystal display panel and a rear polarizing plate and a reflection plate may be fixed on the rear side of the liquid crystal display panel so as to cover the advertisement display unit.
