Background
As a glass substrate which is one of key materials for TFT-LCD or OLED display panels, a mainstream technology for producing a glass substrate in the market at present includes an overflow down-draw method and a float process, and considering that both sides of a glass substrate produced by the overflow method are not contacted with any other medium, a subsequent surface grinding and polishing treatment is not required for a glass substrate produced by the float process, so that the production cost can be reduced.
In the forming process of producing the glass substrate by adopting the overflow downdraw process, the edge roller is used for clamping the edge of the glass substrate, so that the effect of stabilizing the width and the thickness of the glass substrate is achieved.
