By forming a predetermined pattern including a logo and a specific function button on the outer edge portion of the substrate such as a cover glass, the predetermined pattern can be printed directly on the substrate, and the thickness of the pattern is greatly reduced to significantly reduce the quality. It is possible to form a white pattern which is improved, which is not applicable to the conventional exposure method, greatly reduces the overall tact time and manufacturing cost, and the pattern forming printing apparatus, printing system, and It relates to a printing method.

Handheld electronic devices are becoming more and more popular. Examples of handheld electronic devices include handheld computers, mobile phones, media players, smartphones, mobile PCs such as tablet PCs, liquid crystal displays (LCDs), touch screen panels (TSPs), and the like (hereinafter referred to as "mobile devices"). Include.

1 is a view showing an embodiment of a mobile device according to the prior art, Figure 2 is a view showing a cover glass and a predetermined pattern of the mobile device.

1 and 2, the portable device 10 according to the related art may be, for example, a mobile phone or a smartphone. The portable device 10 may include a housing 12. Housing 12 may have bezel 14. This bezel 14 may hold the display 16 in a fixed manner, for example by attaching the display 16 to the housing 12. Display 16 may be implemented as a liquid crystal display (LCD) or an organic light emitting diode (OLED) display, or any other suitable display. The outermost surface of the display 16 may be formed of one or more layers of plastic or glass. In addition, touch screen functionality may be integrated into the display 16 or provided using a separate touch pad device. The cover glass 17 is mounted on the display 16, and the outer edge portion of the cover glass 17 is required to form a predetermined pattern 19 including a logo, a specific function button display unit 18, and the like. Reference numeral 20 may be, for example, a bus connector 20 that allows the mobile device 10 to interface with external components.

As described above, the formation of the predetermined pattern 19 is required on the outer edge portion of the mobile device 10 on the same base material as the cover glass 17 (hereinafter referred to as the "base material 17"). Depending on the color of the ink used to form the predetermined pattern 19, it may be referred to as a black pattern or a white pattern, and blue patterns and red patterns are also used at present (see, for example, the Galaxy S3 model among Samsung smartphones). ).

As a method for forming a predetermined pattern 19 on a substrate 17 such as a cover glass of the portable device 10 described above, a screen printing method or an exposure method using lithography is used.

3A to 3E are diagrams schematically showing a screen printing method for forming a predetermined pattern on a substrate according to the prior art.

3A to 3E, in the screen printing method according to the related art, a substrate 317 located on the table T, and a plurality of pattern openings 312 positioned on the substrate 317 are provided. Screen 310 is used. Screen 310 is positioned spaced apart by gap height H on substrate 317. Both ends of the screen 310 are fixedly mounted to a pair of frames 314 to maintain a constant tension.

3B to 3E, in the screen printing method according to the related art, ink I is provided on the screen 310, and a squeegee 316 slides the ink I in a horizontal direction ( In the A direction) (see FIG. 3B). Thereafter, the squeegee 316 prints the ink I onto the substrate 317 while passing through, for example, the first pattern opening 312a. In this case, the squeegee 316 is forced downward to bring the screen 310 into contact with the substrate 317 (see FIG. 3C). Thereafter, the squeegee 316 prints the ink I onto the substrate 317 while passing through the second pattern opening 312b (see FIG. 3D). Thereafter, the squeegee 316 prints the ink I onto the substrate 317 while passing through the third pattern opening 312c (see FIG. 3D). Meanwhile, in steps 3C to 3E, as the squeegee 316 continues to move horizontally, the first to third pattern openings 312a, 312b and 312c are sequentially spaced from the base 317 so that the screen 310 is described. A constant gap H (see FIG. 3A) is maintained on 317. As a result, the ink I printed on the substrate 317 forms a predetermined pattern 319. Thereafter, the ink I remaining on the screen 310 is removed using a scraper 318 shown in FIG. 3A.

As described above, the screen printing method of the related art using the screen 310 and the squeegee 316 has the following problems.

1. Since the squeegee 316 moves on the screen 310 in a sliding manner and exerts pressure on the substrate 317, the position of the portion under pressure on the substrate 317 also changes. In addition, when the squeegee 316 passes over the plurality of pattern openings 312, since the substrate 317 is not momentarily pressured, the upper surface of the substrate 317 generates a pressure deviation as a whole. The substrate 317 has a thin thickness of about 0.2 mm, and thus the substrate 317 is damaged by the above-described pressure deviation when forming the predetermined pattern 319 using the screen printing method of the prior art, or Can be broken.

2. In addition, overlapping printing is required 2-3 times to form a predetermined pattern 319 on the substrate 317. Accordingly, the predetermined pattern 319 has a thickness of about 8 μm, and the print quality of the predetermined pattern 319 due to the overlapping printing is poor. There arises a problem that the alignment accuracy of 319 is lowered.

3. After the ink I is printed onto the substrate 317, the ink remaining on the screen 310 must be removed by the scraper 318. Therefore, since the material according to the residual ink is consumed, the cost increases, and the processing time due to the removal of the residual ink I increases.

As an alternative embodiment of the screen printing method described above, an exposure method using lithography is used in the prior art.

FIG. 3F is a diagram schematically illustrating an exposure method using lithography for forming a predetermined pattern on a substrate according to the prior art. FIG.

Referring to FIG. 3F, first, the pattern thin film F is deposited or laminated on the substrate 317 (S1). Thereafter, the photoresist PR is completely coated on the thin film F (step S2). Thereafter, after placing the mask M on the photorest PR, the photoresist PR is exposed (step S3). Thereafter, the exposed photoresist PR is developed to form a predetermined pattern 319 on the photoresist PR (step S4). Thereafter, the thin film F is etched (step S5). Thereafter, the photoresist PR is stripped (S6 step). As a result, a predetermined pattern 319 is formed on the substrate 317.

As described above, in the case of using the exposure method using the lithography of the prior art, at least six steps are required, which makes the process complicated and increases the overall process time.

In addition, in order to use the exposure method of the prior art, a complicated large-scale facility is required, and manufacturing cost increases significantly.

In addition, the prior art exposure method has a limitation that it cannot be applied when forming a white pattern using white as color ink. More specifically, in FIG. 3F, when the photoresist (PR) layer is completely coated with white ink and subjected to exposure, a predetermined pattern by exposure due to reflection, refraction, and transmissive properties during exposure due to the characteristics of the white ink. This is because formation of 319 is impossible.

Therefore, a new method for solving the above-mentioned problems is required.

The present invention is to solve the above problems of the prior art, by using a reverse offset printing method or a gravure offset printing method, for example, a mobile PC, such as a smart phone, tablet PC, liquid crystal display (LCD), touch screen panel ( By forming a predetermined pattern including a logo and a specific function button on the outer edge portion of the substrate such as a cover glass of a mobile device such as a TSP), the predetermined pattern can be directly printed on the cover class, and the thin film thickness of the pattern Is greatly reduced and the quality is remarkably improved, it is possible to form a white pattern that can not be applied to the conventional exposure method, the pattern forming printing apparatus on the substrate, the printing system, which greatly reduces the overall process time (tact time) and manufacturing cost, And a printing method.
