Design Optimization of Glass Substrate Handler for Evaporating Process System

The mother glass substrate in OLED is needed to be enlarge for raising its productivity itself as well as the realization of the OLED TV. On the other hand the 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 is demonstrating a new solution of these difficulties through clamping and bending boundary conditions, 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
