A disc containing copper for sapphire polishing; the annular surface of the disc is provided with a spiral grinding groove or concentric circular grinding grooves thereon; and stepped grooves are provided at the edges along both the outer ring and inner ring of the annular surface of the disc. Also provided is a method of repairing discs containing copper facing each other for sapphire polishing, comprising: first step, horizontally and transversely moving an upper disc and a lower disc turning tool, or a lower disc and an upper disc turning tool, and aligning the turning tool with the original position of the grinding groove on the corresponding disc; second step, controlling the upper disc and the lower disc to rotate in opposite directions at the same rotation speed and with the turning tools fixed, controlling the upper disc or the lower disc to be fed transversely, and turning a corresponding grinding groove via the turning tools; third step, removing the turning tools and washing the surface of the corresponding discs.

Disc containing copper for sapphire polishing, and method for preparing discs containing copper facing each other

A touch panel and a preparation method therefor, which relate to the technical field of electronic device preparation. The method for preparing a touch panel comprises: firstly, preparing a BM frame layer (), and then sequentially preparing an ITO1 layer (), an OC1 layer () and an ITO2 layer () in the BM frame layer (); then, preparing a window frame layer () outside the BM frame layer () by means of a printing process; and finally, preparing a designated metal wiring layer () and an OC2 layer (). The touch panel and the preparation method therefor solve the problem that a white window frame in the current industry is yellowed easily. Compared with a yellow light lithography for preparing the window frame, the printing process for preparing the window frame is simpler in production process, higher in defect-free rate and lower in corresponding cost, and can reduce pollution from discharge of wastewater and waste gas generated by the chemical solution to the environment.
