Embodiment Construction

[0020] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0021] figure 1 is a cross-sectional view schematically showing an LC distributor according to an embodiment of the present invention.

[0022] Such as figure 1 As shown, the LC dispenser according to the embodiment of the present invention comprises at least one nozzle 111 through which the liquid crystal is dispensed onto the substrate 10 .

[0023] The nozzle 111 is movable relative to the substrate. The nozzle 111 is connected to a nozzle block 112 installed in the dispensing head unit 110 . The dispensing head unit 110 is supported by the head support frame 102 and is movable in one direction. Both ends of the head supporting frame 102 are fixed to the main body 101 of the LC dispenser, and are movable in a direction perpendicular to the direction in which the dispensing head unit 110 moves. Accordingly, the nozzles 11...

Abstract

The present invention provides a liquid crystal dispensing apparatus which comprises: at least one nozzle which can move relative to a substrate and can drip liquid crystal drop from the nozzle; a supply unit used fro supplying liquid crystal to the nozzle; and a calculating unit which includes a sensor for sensing the drop of liquid crystal from the nozzle and a control unit for checking whetherliquid crystal with reference amount is dispensed by calculating the number of the liquid crystal drops based on the data obtained from the sensor.

Description

technical field [0001] The present invention relates to an LC (Liquid Crystal) dispenser capable of counting liquid crystal drops during dispensing. Background technique [0002] Flat panel displays (FPDs) comprise a growing number of technologies that allow video displays to be much lighter and thinner than conventional televisions and video displays using cathode ray tubes, typically less than 10 cm (4 inches) thick. Flat-panel displays that require constant updating include liquid crystal displays (LCDs), plasma displays, field emission displays (FEDs), organic light-emitting diode displays (OLEDs), surface-conduction electron-emitting displays (SEDs), nano-emission displays (NEDs), and electric Luminescent Displays (ELDs). [0003] A liquid crystal display (LCD) is a thin flat-panel display device made of multiple color or monochrome pixels arranged in front of a light source or reflector. Liquid crystal displays are widely used because they use a very small amount of ...
