Liquid crystal dispensing apparatus having confirming function for remaining amount of liquid crystal and method for measuring the same
View Patent ↗A liquid crystal dispensing apparatus determines an amount of liquid crystal remaining within a liquid crystal container. The apparatus includes a liquid crystal dispensing unit for containing dispensable liquid crystal, capable of be dispensed directly onto a substrate and a main control unit for determining a total amount of liquid crystal dispensed onto the substrate based on a unitary amount of liquid crystal dispensed and the number of times the unitary amount was dispensed, and determining an amount of liquid crystal remaining by deducting the determined total amount dispensed from an initial amount of liquid crystal contained within the dispensing unit.
1. A method of manufacturing a liquid crystal display (LCD) device, comprising:
preparing a first substrate and a second substrate;
dispensing droplets of liquid crystal on the first substrate using a dispenser having a nozzle and a liquid crystal container, wherein said dispensing includes the steps of:
counting a number of droplets dispensed;
determining a total amount of the liquid crystal dispensed on a basis of said counting the number of droplets dispensed; and
determining whether a sufficient amount of the liquid crystal exists in the liquid crystal container to be dispensed to prevent a defect in the LCD device on a basis of said determining the total amount of the liquid crystal dispensed;
forming a seal pattern with a sealant on either the first or second substrate;
bonding the first and second substrates;
curing the sealant;
cutting the bonded first and second substrates;
wherein the liquid crystal is uniformly filled between the first and second substrates and the liquid crystal substantially does not come into contact with the sealant before curing.
