Embodiment Construction

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] A device for controlling liquid crystal dripping according to an embodiment of the present invention mainly includes a head unit, a temporary liquid crystal (LC) storage unit, and a two-fluid control unit. The mechanical configuration and operation of the head unit and the temporary LC storage unit that can be driven by the two-fluid control unit will be described in detail with reference to the accompanying drawings. figure 2 and image 3 is a view showing a mechanical configuration of an apparatus for controlling liquid crystal dropping according to an embodiment of the present invention.

[0019] Such as figure 2 and image 3 As shown, a head unit 1270 has a gas supply path 1250 and a liquid crystal (LC) supply path 1260 therein. The liquid crystal fed via the LC supply path 1260 is dripped onto the substrate through nozz...

Abstract

The invention discloses a device used for controlling liquid crystal dripping, which controls dripping of liquid crystal on a substrate. The device comprises a head part unit, a temporary storage unit and a dual-fluid control unit. The head part unit is provided with a gas supply path and a liquid crystal supply path, liquid crystal supplied via the liquid crystal supply path drip via a nozzle, and liquid crystal drops formed at the end part of the nozzle drip on a substrate via the gas supplied by the gas supply path. The temporary liquid storage unit pumps liquid crystal from a liquid crystal storage vessel and temporarily stores liquid crystal. The dual-fluid control unit controls amount of liquid crystal supplied from the temporary liquid crystal storage unit to the nozzle end part, and adjusts gas used for making the liquid crystal drip from the nozzle end part.

Description

technical field [0001] The present invention generally relates to a liquid crystal dispenser, and more particularly to a device for controlling liquid crystal dripping onto a substrate. Background technique [0002] Generally, a liquid crystal display (LCD) includes a lower substrate, an upper substrate, a sealant, and a liquid crystal layer. The lower substrate has drive devices, such as transistors, on the flat glass. The upper substrate has a color filter layer on the flat glass. A sealant is used to attach the upper and lower substrates to each other. A liquid crystal layer is filled between the upper substrate and the lower substrate. Such an LCD drives liquid crystal molecules in a liquid crystal layer through a driving device formed on a lower substrate, and controls the intensity of light passing through the liquid crystal layer by driving the liquid crystal molecules, thereby displaying information. [0003] According to an LCD manufacturing method, a driving de...
