The quality of photoelectric display glass substrate has a significant impact on the qualified rate of panel factory. In general, the quality control of photoelectric display glass substrate mainly include the control of thickness, warpage, stress and other physical characteristics, as well as the quality control of surface defects, surface particles, inclusions and edge grinding. Actual products in the client use process are still present kinds of raw material (photoelectric display glass substrate) problems due to the different processing technology. In order to improve the quality of photoelectric display glass substrate and reduce the failure rate of products for customers, it is necessary to optimize the quality control of photoelectric display glass substrate, reduce the invalid control and refine the key control items.
