Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification. The dimensions and relative sizes of layers and regions in the figures may be exaggerated for clarity of illustration.

It is to be understood that when an element or layer is referred to as being "on" or " on "of another element or layer, All included.

The terms spatially relative, "below", "beneath", "lower", "above", "upper" May be used to readily describe a device or a relationship of components to other devices or components. Spatially relative terms should be understood to include, in addition to the orientation shown in the drawings, terms that include different orientations of the device during use or operation.

Although the first, second, etc. are used to describe various components, it goes without saying that these components are not limited by these terms. These terms are used only to distinguish one component from another. Therefore, it goes without saying that the first component mentioned below may be the second component within the technical scope of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a view showing a code pattern composed of divided code patterns according to an embodiment of the present invention. FIG. 2 is a view showing a code pattern when divided code patterns shown in FIG. 1 are combined.

1 and 2, a code pattern according to an embodiment of the present invention may include divided code patterns 50A and 50B divided into at least two or more divided code patterns 50A and 50B, The two-dimensional code pattern can be combined with each other to contain one piece of information.

The code pattern may include product information of the display panel constituting the display device described below. That is, when the divided code patterns 50A and 50B are combined into one, they may contain product information of the display panel. More specifically, the information may include information on a display device to which the display panel is to be applied, a production date of the display panel, and a remaining assembly process. However, the present invention is not limited to this, and can be applied to a code pattern applied to other components besides the display panel.

In addition, the divided code patterns 50A and 50B may include a long side and a short side, respectively, and may have a rectangular shape.

More specifically, as shown in FIG. 1, the divided code pattern includes a first divided code pattern 50A and a second divided code pattern 50B, and the first divided code pattern 50A and the second divided code pattern 50B May each be a rectangular shape including a long side and a short side. At this time, the length of the long side is the same, and the first divided code pattern 50A and the second divided code pattern 50B are combined with each other in the long side direction on the software for recognizing a code pattern to be described later to form one code pattern And may include one piece of information. In other words, when the first divided code pattern 50A and the second divided code pattern 50B are combined in the long side direction, the length of the long side may be fixed and the length of the short sides of the short side may be combined have.

2, the combined code pattern 55 may include a long side and a short side, and the first divided code pattern 50A and the second divided code 50A may include a long side and a short side, The pattern 50B may be a shape divided in the long side direction of the combined code pattern 55. [

Each of the divided code patterns is thinner in the short side direction than the combined code pattern 55 including a single piece of information so that the divided code pattern can be easily arranged on a display panel to be described later. More specifically, since the divided code pattern can be located on the non-display area on the display panel and is thinner than the combined code pattern, the code pattern can be formed even if the area of the non-display area is small. Thus, the size of the non-display area, that is, the bezel can be reduced. In addition, since it is possible to freely change the position of the divided code pattern divided by the method of recognizing each of the divided code patterns to be described later and analyzing the information, it is easy in the process.

On the other hand, in general, the code pattern has a predetermined size, which is located in the non-display area of the display device. The non-display area is generally referred to as a bezel, and in recent years, studies are under way to reduce the size of the bezel. Meanwhile, studies have been made to reduce the size of the code pattern as the size of the bezel decreases. However, in order to reduce the size of the code pattern itself, it is necessary to reduce the size of the dot forming the code pattern. In this case, a reader device for recognizing a code pattern corresponding to a reduced dot size must be newly introduced, which is a large cost, resulting in an increase in the product cost.

Thus, the present invention can analyze the information of the code pattern located on the display panel by forming the code pattern into the divided code pattern without reducing the dot size forming the code pattern. That is, each of the divided code patterns is recognized and analyzed, and the information is acquired by the combined code patterns, and the divided code patterns are combined into one code pattern without introducing a new reader to recognize a code pattern with reduced dot size The same information can be acquired and analyzed even in a narrow non-display area only by changing the software, so that it can be very advantageous in terms of cost and process as compared with reducing the overall size of the code pattern.

On the other hand, the lengths of the short sides of the first divided code pattern 50A and the second divided code pattern 50B may be different from each other. The divided code pattern 50 can be divided into the first divided code pattern 50A and the second divided code pattern 50B in accordance with the desired short side size, The ratio of the length of the short side to the long side of the code pattern 50A and the second divided code pattern 50B may be larger.

In other words, in the display panel to be described later, the code pattern can be located in the non-display area, and the code pattern is divided into the first divided code pattern 50A and the second divided code pattern 50B, So that the length of the short side in the longitudinal direction is shorter, thereby reducing the size of the non-display area.

FIG. 3 is a diagram illustrating a code pattern including a divided code pattern according to another embodiment of the present invention. Referring to FIG. 3, the divided code pattern may further include a third divided code pattern 50C. That is, the divided code pattern can be divided into three portions and divided into the first divided code pattern 50A to the third divided code pattern 50C. In this case, the lengths of the long sides may be equal to each other. The lengths of the shorter sides of the divided code patterns of any of the first divided code patterns 50A to the third divided code patterns 50C may be shorter than the lengths of the shorter sides of the divided code patterns different from each other They can be different, such as long or short.

4 and 5, the code pattern includes a first alignment mark 70-A formed on a side of one short side of the first divided code pattern 50A, and a first alignment mark 70- And a second alignment mark 70-B formed on the side of one short side and corresponding to the first alignment mark 70-A. For example, the first alignment mark 70-A may be formed in a pattern in which a certain type of mark is empty, and the second alignment mark 70-B may be a pattern in which the first alignment marks 70- -A). [0060] The pattern shown in Fig. In other words, the first alignment mark 70-A and the second alignment mark 70-B may include mutually complementary patterns, and the first alignment mark 70-A and the second alignment mark 70- When the in-marks 70-B are combined and aligned, a complementary pattern is combined and can be aligned.

In other words, the shapes of the first alignment mark 70-A and the second alignment mark 70-B may be complementary to each other so as to have specific positions. For example, if the first alignment mark 70-A has a cross shape as shown in FIG. 4, the second alignment mark 70-B may have a cross shape of the first alignment mark 70-A And may have a shape other than the shape shown in Fig. Accordingly, the first divided code pattern 50A and the second divided code pattern 50B are formed in a desired shape (e.g., a rectangular shape) by the mutually complementary shapes of the first alignment mark 70-A and the second alignment mark 70- And can be aligned to position.

5, when the first alignment mark 70-A and the second alignment mark 70-B are combined to form a combined alignment mark 70, The first divided code pattern 50A and the second divided code pattern 50B also form a combined code pattern 55 in a desired shape. 5, the first divided code pattern 50A and the second divided code pattern 50B, which have been divided, can be combined into one divided code.

The first alignment mark 70-A and the second alignment mark 70-B may be formed on the side surfaces of the first divided code pattern 50A and the second divided code pattern 50B in the same direction. That is, as described above, the first divided code pattern 50A and the second divided code pattern 50B may each include a long side and a short side, and the first aligned mark 70-A May be formed on the right side of the right side of the first divided code pattern 50A and the second aligned mats 70-B may be formed on the right side of the right side of the second divided code pattern 50B . Thereby, the first divided code pattern 50A and the second divided code pattern 50B located on the same side with respect to the first alignment mark 70-A and the second alignment mark 70-B It can be arranged in a desired position and recognized as a single code pattern on the software.

However, the present invention is not limited thereto.
