Abstract: There are provided a method for calculating an amount of liquid crystal to compensate for any of shortage and excess of sealant dispensed on a substrate, Include putting the substrate on a stage, dispensing the sealant in a predetermined pattern on the substrate using a dispensing head, detecting an out-of-specification portion of the pattern of sealant and calculating a cubage of the out-of-specification portion of the pattern of sealant, and calculating any of shortage and excess of sealant due to the out-of-specification of the pattern of sealant. The liquid crystal dispenser adjusts a reference amount of liquid crystal to be dispensed, according to the data provided from the controlling unit of the sealant dispenser. This prevents the liquid crystal from being excessively dispensed, thereby overflowing over the pattern of sealant, or from being insufficiently dispensed.

Abstract: There is provided a method for inspecting a pattern of paste which a dispenser forms on a substrate, including putting the substrate on a stage; dispensing the paste on the substrate according to a relative distance between a nozzle and a surface of the substrate which a measuring unit measures in real time; storing data on the relative distance which is obtained from the measuring unit; selecting a point corresponding to data falling outside the predetermined range from among the stored data and designating the selected point as an inspection point; translating the data falling outside the predetermined range into a positional value and moving a dispensing head to a position over the inspection point on the pattern of paste corresponding to the positional value; and inspecting at the inspection point if there exists a defect on a pattern of paste.
