While the blade 201 is moved along the vertical or horizontal direction, the protective film layer 700 is sectioned and cut in units of cells (S200).

  At this time, the cutting plotter 200 is connected to an external device (not shown) to receive a signal value input to the external device, and moves the cutter blade 201 to a predetermined position, so that the protective film The layer 700 is cut, and the cell-based protective film layer 700 cut in this way is preferably sized to meet the specifications of the product in which the touch screen is used.

In this state, while moving the sand blaster 300 along the boundary line 700a, the tempered glass plate 600 is cut to obtain a large number of cell unit glass substrates 600a (S300).

  That is, the sand blaster 300 is moved along the boundary line 700a formed on the upper surface of the tempered glass plate 600, and the upper surface of the tempered glass plate 600 is cut at a predetermined depth, and the tempered glass is cut. When rotated so that the lower surface of the plate 600 is positioned at the upper end, the upper surface of the tempered glass plate 600 is moved along the boundary line 700a of the protective film layer 700 removed at the lower surface of the tempered glass plate 600. The tempered glass plate 600 is cut at a predetermined size by cutting a portion corresponding to a plurality of cell unit glass substrates 600a on which the G2 touch sensor is formed. To gain.

  Here, the sand blaster 300 is a method of finely finishing and maintaining the surface of a metal product such as a casting by injecting sand with compressed air, and the sand blaster 300 of the present invention includes an alumina silicate # 400 polishing. Agent is used.

  In particular, the abrasive sprayed by the sand blaster 300 is blocked by the protective film layer 700 formed on the glass plate 600, and the glass plate 600 is cut beyond the boundary line 700a of the protective film layer 700. It is prevented.

  Meanwhile, in this process (S300), the humidity is maintained at 50 to 60%, the temperature is maintained at 22 to 25 degrees (° C.), and the nozzle 301 of the sand blaster 300 and the glass plate 600 for injecting the abrasive are used. It is desirable to cut the glass plate 600 by spraying an abrasive at a pressure of 3.0 MPa and moving it at a moving speed of 50 to 70 mm / sec with the distance between them being 20 mm apart.

  A number of the cell unit glass substrates 600a obtained above are protected by the protective film layer 700, and a G2 touch sensor 601 is formed on the upper surface of the cell unit glass substrate 600a.

  Here, it is preferable that the user removes the protective film layer 700 using a triangular cone having a diameter of 50 μm.

  In particular, in this process (S500), the cell unit glass substrate 600a of 100 to 200 sheets or less is simultaneously immersed in the fluffy water tank 500, and the cell unit glass substrate 600a of one cane in that state is sequentially added. The user removes the protective film layer 700.

  The G2-type touch screen manufactured through the plurality of steps as described above grasps the position where the glass substrate 600a responds to a hand or a specific object and a signal is input.

At this time, the electrical property is made to flow through the probe pin 801, so that the G2 method of the G2 touch screen is used. Whether or not the touch sensor 601 is damaged and whether or not a touch malfunction is detected are checked.

  Then, the G2 touch screen is finally cleaned to remove dust or moisture remaining on the G2 touch screen, and then the user uses the three-wavelength fluorescent lamp with the naked eye, and the G2 touch screen is used. Inspects scratches, foreign objects, microcracks, and chipping generated on the touch screen.

  In this way, a packaging operation for attaching the film to the upper and lower surfaces of the G2 touch screen that has been inspected is performed to prevent the G2 touch screen from being scratched.

  Here, the short inspection, cleaning, inspection and packaging operations performed after the step (S500) are performed by a general method, and detailed description thereof will be omitted.

  As described above, after forming the protective film layer 700 on the single tempered glass plate 600 on which the plurality of G2 type touch sensors 601 are formed, the method of manufacturing the G2 type touch screen by dividing and cutting is a plurality of G2 The glass substrate 600a with the G2 touch sensor 601 is obtained by cutting the tempered glass plate 600 on which the touch sensor 601 is formed, thereby increasing the production efficiency, thereby enabling mass production and protection.
