Description

{Pair glass with the function of electronic display and illumination}

DISCLOSURE TECHNICAL FIELD [0001] The present invention relates to an electronic display panel and a multilayer glass having an illuminating function, and more particularly, to an electronic device using a discrete LED as a light source for maintaining transparency, And an illuminating function, and a multilayer glass having an illuminating function.

Herein, the background art relating to the present invention is provided, and they are not necessarily referred to as known arts.

The double-layered glass means a glass in which two sheets of glass are adhered to each other with an adhesive agent at regular intervals and sealed with completely dry air in the middle, and is also referred to as a pair glass.

Double-layered glass has effects such as heat insulation, sound insulation and dew condensation, and is widely used for construction.

However, since the double-layered glass generally does not have the function of controlling the transmittance of light, it has conventionally been a common practice to separately adjust the amount of light by providing a blind.

In recent years, the so-called 'smart glass' which can control the light transmittance by power using a polymer dispersed liquid crystal (PDLC) has been introduced and applied to a construction site.

However, even in the case of 'smart glass', it is merely used to transmit or opaque light, and thus it has a limitation in its use.

For this reason, there is an increasing need for research to broaden the application range of 'smart glass'.

The present inventor has recognized the usefulness of a double-layered glass capable of imparting a lighting function to people inside a building having a function of a signboard for visually transmitting predetermined character information or images to people outside the building, .

Specifically, in order to realize a double-layered glass capable of expressing a moving image or an image, at least one of the two glasses should be provided with a light emitting element.

However, when a large number of light emitting devices are installed, there is a problem that the light emitting devices are not transparent or the transparency is reduced due to the complicated wiring connecting the light emitting devices, and the manufacturing cost is also increased.

In this case, it becomes the same as opaque light emitting device or electric signboard, and the window function of the multi-layered glass is not properly performed.

As a result, the development of a structure capable of performing an electric display board and a lighting function by using discrete distributed light emitting elements is the core of the present invention.
