  • the present invention relates to a glass scribing method and apparatus capable of preventing problems such as cracking of a screen by inducing a direction of a horizontal crack generated in cruising outside the touch sensor, and a touch sensor including glass cut by the glass.
  • the touch sensor includes an object, a touch switch, and a printed circuit board connected to the touch switch.
  • the touch sensor When the touch sensor is mounted on a specific object and the user touches the touch sensor, the object may operate.
  • the capacitive touch sensor is a sensor that detects minute capacitance of the body or a specific object, and detects contact when the body and the object having the capacitance touch each other.
  • the touch sensor uses a glass substrate that absorbs shock from the outside and protects the touch module.
  • the cutting of the glass substrate generally proceeds in a so-called scribe manner, in which the glass substrate is cracked in a certain form.
  • a mechanical cutting method and the other is a laser cutting method using laser light irradiation.
  • the glass is cut by applying a pressure to the glass to generate a median crack, that is, a crack extending in a direction perpendicular to the glass surface.
  • the glass cut surfaces thus formed are brought into contact with each other in the pressure release step of the blade, so that lateral cracks, that is, horizontal cracks extending in a direction horizontal to the glass surface, are generated.
  • FIG. 3 is an enlarged view of a portion A of FIG. 2. Referring to FIG. 3, it can be seen that horizontal cracks are minutely generated inside the screen. Accordingly, there is a need for a new method and apparatus for scribing glass that leads the direction of horizontal cracks generated during the scribing process to the outside of the screen, which is more so in view of the curved portable terminal characteristics.
  • an object of the present invention is to provide a glass scribing method and apparatus capable of minimizing cracking of an actual screen by inducing horizontal cracks occurring on a glass substrate during the scribing process to the outside of the effective touch sensor.

  • the glass substrate is scribed in a curved form by a combination of small straight lines, and the horizontal cracks generated in the curved scribing are guided to the outside of the touch sensor, thereby preventing cracks on the screen. Problems can be prevented. Therefore, the screen size can be maximized in the portable terminal of the curved bezel.

  • the present invention solves the infiltration direction of the horizontal crack generated by scribing the glass with the actual curve with a plurality of straight scribes, and the shape of the curve is achieved by connecting a plurality of straight lines with a constant angle change. . That is, according to the straight scribing, the horizontal crack proceeds on an extension line of the straight line, whereby the horizontal crack proceeds to the bezel area instead of the screen.

  • the curved glass is particularly useful for a mobile phone terminal having a circular terminal shape, because it induces horizontal cracks to the outside of the screen and minimizes the size of the bezel and reduces the effective area of the touch sensor. This is because it can be configured to the maximum.

Abstract

L'invention concerne un procédé et un appareil de traçage sur verre et un capteur tactile incluant un verre avec un traçage effectué de cette façon. Dans le procédé de traçage sur verre selon la présente invention, un traçage linéaire peut être continuellement effectué plusieurs fois pour obtenir un traçage sur verre dans une forme courbe. Ici, le traçage linéaire qui est effectué plusieurs fois est changé à un angle prédéterminé. Selon la présente invention, de petites lignes droites peuvent être combinées pour obtenir un traçage sur le verre de forme courbe, et une direction d'une fissure horizontale générée par l'opération de traçage en courbe peut être induite sur l'extérieur du capteur tactile pour empêcher l'écran d'être fissuré. Ainsi, on peut maximiser une taille d'écran dans une facette courbe d'un terminal portable.
