Problems solved by technology

However, since the organic matter is laminated on one side of the organic light emitting diode substrate, chips scattered when grinding the upper edge of the substrate are embedded in the organic matter laminated surface of the organic light emitting diode and cannot be easily removed.
Like this, debris embedded in the organic laminated surface can be a cause of poor organic light emitting diodes

Abstract

A multi-grinding wheel for an OLED(Organic Light Emitting Diode) substrate with high grinding quality and a method for grinding an OLED substrate using the multi-grinding wheel are provided to maintain grindability and minimize chipping in grinding by employing an elastic binder and controlling the grain size and shape of diamond particles of a grinding tip. A multi-grinding wheel for an OLED substrate with high grinding quality comprises a core member(210), wheel bodies(220,220a,220b), and grinding tips(225). The core member has a hollow portion to which a rotary shaft is coupled. The wheel bodies are separated in the axial direction of the rotary shaft and coupled to the exterior of the core member. The grinding tips are formed on the exterior of the respective wheel bodies. In the grinding tips, an elastic binder fixes grinding particles including diamond particles so as to reduce the chip scattered when grinding an edge of an organic compound laminated surface of an OLED substrate.

Description

technical field [0001] The present invention relates to a technique for manufacturing a grinding wheel for grinding organic light emitting diode substrates, and more particularly, relates to a technique capable of making the edge of an organic light emitting diode substrate be ground, especially when grinding the edge of an organic laminated surface. A multifunctional grinding wheel that minimizes chipping and minimizes debris flying to organic matter, and a method for grinding an organic light emitting diode substrate using the multifunctional grinding wheel. Background technique [0002] Currently, most displays are based on Liquid Crystal Displays. [0003] As far as the glass panel for liquid crystal display is concerned, the edge (edge) of the glass panel is processed by grinding the edge (edge) of the glass panel with a multifunctional grinding wheel with an outer diameter of about 130 mm. [0004] On the other hand, recently, a lot of research is being carried out on...
