Abstract
The invention discloses an edge polishing method and device of display glass. The method and device are characterized in that four edges of the display glass are cut to form four end surfaces and four section surfaces during the subsequent processing of touch glass, then the edge of the end surface of the display glass is polished only, and thus the area of a micro crack caused by the edge polishing can be reduced; the display glass subjected to end surface edge polishing is etched with a mixed acid solution; therefore, the micro crack in the display glass caused by the edge polishing can be effectively decorated, and as a result, the four-point bending resisting testing capacity of a touch glass product can be effectively improved; compared with the traditional edge polishing processing method of the display glass, the method has the advantages that the end surface of the display glass is subjected to edge polishing only, and thus the area of the micro crack can be effectively reduced; after the etching processing of the mixed acid solution, the micro crack produced by the edge polishing can be effectively reduced, and as a result, the mechanical bending resisting capacity of the touch glass product can be obviously improved.
