Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a touch screen panel protective sheet,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet for protecting a touch screen panel and a method of manufacturing the same, and more particularly, to a touch screen panel attached to an upper portion of a display screen terminal to prevent scratches of the touch screen panel, and to protect the touch screen panel from external impact. A panel protective sheet and its manufacturing method.

As the spread of display display terminals (mobile phones, smart phones, notebooks, tablet PCs, digital cameras, navigation devices, game devices, robots, electronic notebooks, etc.) using touch screen panels such as LCDs, PDPs and OLEDs has dramatically expanded, A touch screen panel with a convenient touch function is rapidly enlarged and used.

Accordingly, protective films made of general synthetic resin, which is attached to the upper part of the touch screen panel to protect the touch screen panel and prevent scratches, are widely used

The protective film made of synthetic resin is hard coated to improve the surface hardness on PMMA (Poly Methyl Acrylate), PET (Poly-Ethylene Terephthalate), PC (Poly Carbonate), etc. Doing.

However, most of the protective film made of synthetic resin is 1H to 6H, the surface hardness of which is not high, and is weak to general life scratches, and there is a problem in using a clean and clear touch screen panel as scratches are easily generated.

In addition, since the protective film made of a synthetic resin is made of a plastic material, it is resistant to heat resistance, chemical resistance, physical properties, and the thickness is thin, so that it is difficult to adhere and the impact protection function is weak.

In order to solve these problems, a protective film having a surface hardness of at least 10% has been recently developed. However, the tempered glass has a surface hardness of 9H or more and does not cause life scratches.

FIG. 1 is a detailed configuration diagram of a conventional touch screen panel protection sheet.

Referring to FIG. 1, a conventional screen for protecting a touch screen panel using a tempered glass layer has a shatterproof film layer 106 in order to eliminate the risk of breakage of the glass due to the nature of the glass, It should be lined.

It is necessary not only to provide a separate double-sided adhesive coating layer 105 between the tempered glass layer 101 and the anti-scattering film layer 106 in order to adhere the anti-scattering film layer 106 to the tempered glass layer 101, The adhesive coating layer 107 for adhering to the touch screen panel should be provided at the lower end of the anti-scattering film layer 106.

An adhesive coating layer 107 should be formed on the anti-scattering film layer 106 (PET film or the like) to form the adhesive layer 105, and a reinforcing glass layer 101 is formed on the opposite surface of the anti- The double-sided adhesive coating layer 105 or the highly transparent double-sided adhesive film must be subjected to a lamination treatment through a separate process.

The inner fingerprint coating layer 102 may be formed on the upper end of the tempered glass layer 101 and the half mirror coating layer 104 may be formed on the lower end of the tempered glass layer 101.

Thereafter, the shatterproof film layer 106 coated with the double-sided adhesive coating layer and the adhesive coating layer 107 is punched into a touch screen panel shape to be individualized, and each sheet is subjected to a complex and many processes with the tempered glass layer 101. After laminating, the protective release film 108 is attached to the bottom of the tempered glass layer 101.

However, since the conventional touch screen panel protective sheet produced through the above-described process has undergone several steps of coating and lapping processes through a roll process, expensive equipment is required and the bubbles during coating and laminating processes There is a high probability that a defect occurs.

In addition, there is a disadvantage that mass production of small quantities of products is required due to the nature of the roll process.

On the other hand, Korean Patent No. 1050250 discloses that a pattern layer is formed under a tempered glass layer corresponding to a frame region except a display region (liquid crystal portion or display region) of a display display terminal, and then an adhesive layer is formed only at the bottom of the pattern layer The display is attached to the front of the touch screen panel of the terminal.

However, this is not only dangerous when the tempered glass layer is broken due to lack of scattering prevention function, but also has a very thin empty space between the touch screen panel protecting sheet and the display area of the display display terminal because the adhesive layer is formed only at the bottom of the pattern layer do.

Therefore, when the center of the display area touches the touch screen panel protection sheet due to the thin space, a phenomenon such as a rainbow and a water droplet (water mark) may occur.

In addition, in order to solve this problem, a product having an uncoated film layer at the bottom of the tempered glass layer and having a concave-convex treatment on the upper or lower surface of the uncoated film layer has been developed, but it has to undergo a complicated layer formation and many processes. Therefore, there is a problem that the manufacturing cost rises.

In addition, in the case of a small-sized touch screen panel protective sheet, it was possible to solve some defects such as rainbow and water droplets through a rough surface treatment. However, in the case of large-sized touch screen panel protection applied to smart phones, tablet PCs, In the case of the sheet, the defects of the rainbow and water droplet phenomenon could not be solved.

In addition, the unevenness of the unevenness of the uncoated film layer has a problem that the transmittance is low and the sharpness of the display is deteriorated.

Referring to FIG. 2, the conventional color-printed touch screen panel protective sheet forms a printed layer 204 on the tempered glass layer 201 to be attached to the double-sided adhesive film layer 206.

However, in the case of a touch screen protective sheet produced through a roll process having a thickness of the print layer 204 of 5 mu m or more in general, the double-sided adhesive coating layer 206 formed at the lower end of the print layer 204 due to the step difference, The anti-scattering film layer 207 and the adhesive coating layer 208 all have stepped portions.

Therefore, when attaching the touch screen panel protective sheet printed with the finely formed stepped color to the display display terminal, there is a problem that bubbles are generated as shown in 209.
