In order to raise productivity of the OLED and realization of the OLED TV, the enlargement of the mother glass substrate is required. The large-size glass substrate has some difficulties regarding its deflection during handling operation due to its thin thickness (0.5$\sim$0.7t) which is not even enough to stand its mass itself. This paper is demonstrating a new solution of this difficult through clamping and bending boundary condition, which helps to minimize the deflection of the glass substrate. Based on the developed method, the experiments had been done for verifying the proposed method to minimize the glass-deflection. With the developed method, the new design of glass substrate handler can be proposed to allow the large OLED displays be manufactured.
