Patent ID: 7785655

Claim:
A liquid crystal dispensing method, comprising the steps of: calculating a dispensing amount and a dispensing position of liquid crystal and setting a liquid crystal dispensing system; driving a substrate and to position a liquid crystal dispensing system at the dispensing position; controlling a fixation angle of a discharge pump by driving a second motor in accordance with the calculated dispensing amount; operating the discharge pump by driving a first motor to dispense liquid crystal onto the substrate; measuring a dispensing amount of liquid crystal dispensed onto the substrate; calculating a differential value between the measured dispensing amount and the preset dispensing amount; comparing the differential value with a second limitation value; comparing the differential value with a first limitation value; converting the differential value into a pulse value when the differential value is greater than the first limitation value and less than the second limitation value; and inputting the converted pulse value to the second motor and controlling a fixation angle of the discharge pump.
