A bonding machine for fabrication of a large size LCD having an upper stage and a lower stage provided in a bonding chamber to face each other, for adsorbing the first and second substrates carried in the bonding chamber, and bonding the substrates together. The transmitting station evaluates the frame error rate as a function of energy. In particular, the invention provides UV barrier formulations for polyester resins that have improved resistance to ultraviolet radiation, and significantly reduce ultraviolet light transmission in the resulting resin products. The power setup data may be represented by a substantially linear equation relating the input voltage to the output laser power. Responsive to the thread activity levels differing from the known profile beyond a second predetermined threshold, an indication of suspected abnormal activity associated with the given functional unit is sent.
