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 liquid crystal dispensing unit.
1. A method of manufacturing a liquid crystal display (LCD) device, comprising:
providing a first substrate;
providing a second substrate;
dispensing a liquid crystal stored in a liquid crystal container on either the first or second substrate;
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; and
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,
wherein said dispensing step comprises measuring and weighing the liquid crystal in the liquid crystal container using a scale arranged between an upper surface of a fixing member and a lower surface of an upper cap, wherein the scale determines a weight of the liquid crystal dispensing unit, and determining and displaying using a display unit 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.
