Study on Gripping Large-size FPD Glass Substrates

The mother glass substrate in FPD is needed to be enlarging for raising its productivity itself as well as the realization of the world-widely TV. Especially the mother glass in OLED is needed uniformly distributed gripping force to handle deflection of the glass. Because large-size glass substrate has some difficulties regarding its deflection during handling operation due to its thinness (0.5-0.7t) which is not even enough to stand its mass itself. This study aims to demonstrate a new solution of these difficulties through clamping and bending boundary conditions of the hinge type, which help to minimize the deflection of the glass substrate. The experiments had also been carried out to verify the proposed method for minimizing the glass-deflection. This new design of glass substrate handler may be useful in manufacturing the large OLED displays.
