Configuration of Light Emitting Glass 100

1 is a view showing the configuration of a light emitting pattern glass 100 according to an embodiment of the present invention.

First, the light emitting pattern glass 100 according to an embodiment of the present invention may be used for the light emitting pattern display device 10. The light emitting pattern glass 100 may be made of tempered glass having excellent hardness, and by employing such a configuration, in the present invention, the light emitting pattern glass 100 does not easily cause warpage or surface scratches. You can do it. In particular, the light emitting pattern glass 100 may be composed of a low iron tempered glass containing a small amount of iron among various tempered glass, by employing such a configuration, in the present invention, light emission that can minimize the loss of incident light It is possible to provide a patterned glass 100.

Referring to FIG. 1, it can be seen that the light emission pattern 110 is formed on the light emission pattern glass 100. The light emitting pattern 110 may be configured in the form of a specific pattern, characters, symbols, etc. to have an intended message. Accordingly, when light is incident on the light emitting pattern glass 100, the intended message of the light emitting pattern 110 may be displayed to the outside. On the other hand, as shown in Figure 1, the light emitting pattern 110 may have a form of a so-called concave-convex pattern consisting of a concave pattern and a convex pattern.

Hereinafter, a method for manufacturing the light emitting pattern glass 100 as described above will be described.

Method of manufacturing the light emitting pattern glass 100

2 to 4 are views for explaining a method of manufacturing a light emitting pattern glass 100 according to an embodiment of the present invention.

First, referring to FIG. 2, a mask pattern 20 having a predetermined area and shape may be formed on the glass substrate 102. The mask pattern 20 may include specific shapes, characters, symbols, and the like for displaying the intended message to the outside. Meanwhile, the glass substrate 102 may be made of low iron tempered glass as described above.

According to an exemplary embodiment, the mask pattern 20 may be any one of a photoresist pattern, a tape pattern, and an ink pattern having acid resistance. Here, the mask pattern 20 is configured to have acid resistance in order to prevent the emission pattern 110 from being accurately formed as the mask pattern 20 is removed in the wet etching process described later.

When the mask pattern 20 is formed of a photoresist pattern, a photolithography process, which is a known patterning technique, may be used. Hereinafter, a process of forming the mask pattern 20 using the photolithography process will be described.

First, a photoresist film (not shown) having a predetermined thickness may be formed on the glass substrate 102. It is assumed here that the photoresist film is negative.

Next, ultraviolet rays passing through the fine pattern forming mask (not shown) are irradiated to the photoresist film to selectively expose the photoresist film. By this process, the exposed portion of the photoresist film is activated and has a change in dissolution properties, thereby causing a change in dissolution properties between the exposed and unexposed areas in the photoresist film.

Next, a so-called PEB (Post Exposure Bake) process which heat-treats the exposed photoresist film at high temperature is performed. The PEB process may serve to promote a cross-linking reaction so that the photoresist film exposed by ultraviolet light does not react with the developer, thereby improving the resolution of the photoresist film. In some cases, the above PEB process may be omitted.

Next, the photoresist film is developed with a known developer to remove the photoresist film in a region not exposed to ultraviolet light. Accordingly, as shown in FIG. 2, a mask pattern 20 may be formed on the glass substrate 102.

When the mask pattern 20 is formed using the photolithography process as described above, since the mask pattern 20 can be formed more precisely, the light emitting pattern 110 having a high resolution by the wet etching process described later is described. ) Can be easily formed.

Next, referring to FIG. 3, the protective film 30 may be attached to the edge surface and the bottom surface of the glass substrate 102. The protective film 30 may perform a function of preventing the etching solution from contacting the edge surface and the bottom surface of the glass substrate 102 during the wet etching process described later. Tape or ink may be used as the protective film 30, but is not necessarily limited thereto.

Next, referring to FIG. 4, the upper portion of the glass substrate 102 may be chemically wet-etched using the mask pattern 20 as a mask. Here, chemically wet etching the upper portion of the glass substrate 102 may mean etching the upper portion of the glass substrate 102 by chemically reacting the glass substrate 102 with a predetermined etching solution. By such a chemical wet etching process, the light emitting pattern 110 may be formed in the form of a specific pattern, characters, symbols, and the like.

The conventional sand blasting method has a problem that it is difficult to apply to a high tempered glass because of the physical etching method. However, according to the present invention, the above-described problem does not occur because the chemical wet etching method is used. In other words. The light emitting pattern 110 can be easily formed on the upper part of the tempered glass substrate 102 having high hardness.

According to an embodiment of the present invention, a spray process may be used to chemically wet-etch the upper portion of the glass substrate 102. Herein, the spray process may mean a process of spraying the first etchant on the glass substrate 102. As the first etching solution, a solution containing at least one of hydrofluoric acid, sulfuric acid, nitric acid, and phosphoric acid may be used. In addition, the first etchant may be sprayed onto the glass substrate 102 through one or more nozzles.

In this spraying process, the angle between the glass substrate 102 and the ground may be variously adjusted. For example, the spray process may be performed in a state where the glass substrate 102 and the ground are perpendicular to each other, or the spray process may be performed in a state where the glass substrate 102 and the ground are horizontal. In some cases, the spray process may be performed in a state where the glass substrate 102 has a predetermined angle with respect to the ground.

In addition, according to an embodiment of the present invention, a dipping process may be used to chemically wet-etch the upper portion of the glass substrate 102. Here, the dipping process may mean a process of dipping the glass substrate 102 in the second etching solution. As the second etchant, a solution containing at least one of hydrofluoric acid, sulfuric acid, nitric acid, and phosphoric acid may be used similarly to the first etchant.

 Meanwhile, the upper portion of the glass substrate 102 may be etched by performing only one of the above-described spraying and dipping processes, but in some cases, the upper portion of the glass substrate 102 may be formed by performing both of the above-described processes. It can be etched. In this case, when both processes are performed, the spray process may be performed prior to the dipping process.

Next, the light emitting pattern glass 100 as shown in FIG. 1 may be manufactured by removing the mask pattern 20 and the protective film 30. When removing the mask pattern 20 and the protective film 30, it is necessary to be careful not to damage the light emitting pattern 110 formed on the glass substrate 102. In order to remove the mask pattern 20, peeling liquids, such as potassium hydroxide or sodium hydroxide, can be used, and a well-known photoresist stripping liquid can also be used in some cases.

The light emitting pattern glass 100 manufactured as described above may be used as a main component of the light emitting pattern display device 10 described below. Hereinafter, the light emitting display device 10 will be described.
