Patent ID: 7691432

Claim:
A method for forming a liquid crystal display panel comprising: providing a first substrate and a second substrate, the first substrate including a plurality of thin film transistors, pixel electrodes, and a common voltage line, the second substrate including a color filter layer and a common electrode; loading the first substrate having a plurality of panel regions on a table; providing a dispenser having syringe; determining a first flow amount of gas by supplying a gas to a syringe filled with a silver, wherein the first flow amount of gas is the amount of gas necessary for the syringe to be capable of dispensing in response to an additional amount of gas; determining a second flow amount of gas by supplying the gas to the syringe, wherein the second flow amount of gas is the amount of gas such that the syringe is filled with the minimum quantity of residual silver that is enough to ensure a previous dispensing but not enough for a subsequent; repeatedly dispensing the silver using the syringe filled with the silver onto the common voltage line of the first substrate by supplying intermediate flow amounts of gas to the syringe and moving the table on which the first substrate is loaded; detecting the intermediate amounts of gas corresponding to the dispensed amount of the silver in the syringe; and determining a residual quantity of the silver remaining in the syringe by comparing the sum of the intermediate amounts of gas with the second flow amount of the gas; and connecting the common voltage line of the first substrate and the common electrode of the second substrate through the silver; wherein the silver is still dispensed if the sum of the intermediate amounts of gas is less than the second flow amount of the gas.
