Fig. 4 is a vertical cross-sectional view showing the position of the piston 22 when the compression is struck by the cylindrical member 21 of the coating head unit 2 of Fig. i and the piston 22 mounted in the cylindrical member 21. Figure 5 is a horizontal cross-sectional view showing the position of the piston 22 when the compression is struck by the tubular member 21 of the coating head unit 2 of Figure 1 and the piston 22 attached to the tubular member 21A. The dotted arrows shown in Figs. 2 to 5 indicate the direction in which the liquid crystal flows into the cylindrical member. The solid lines shown in Figs. 2 to 4 respectively indicate the direction in which the piston 22 rotates and slides up and down. As shown in Figs. 2 and 3, the cylindrical member 21 has an inflow opening 21a on the inner wall. A predetermined amount of liquid crystal flows into the liquid crystal suction space 8 201005397 S in the cylindrical member 21 through the inflow opening 21a. The cylindrical member 21 has an outflow opening 21b on the inner wall. The outflow opening 21b is opposed to the inflow opening 21a. The liquid crystal droplets are discharged through the outflow opening 21b and the nozzle N. The inflow opening 21a and the outflow opening 21b are connected to the cylindrical member in which the piston 22 slides upward and downward. A line (not shown) is connected between the inflow opening 2la and a container (not shown) containing liquid crystal. A line (not shown) is connected between the outflow opening 2ib and the nozzle N. The side of the piston 22 is provided with a groove 22a. The groove 22a can be formed by cutting a part of the piston 22 in the longitudinal direction. The piston 22 rotates about the Z axis in the cylinder member 21 and slides up and down in the z-axis direction. A method of applying a liquid crystal amount to a panel region of a mother substrate by using a liquid crystal coater having the above configuration will now be described. The nouns used herein are defined as follows. The liquid crystal suction space S is a space formed between the head of the piston 22, the wall surface of the cylindrical member 21, and the bottom side 21c of the cylindrical member 21. Panel area: an area defined where the liquid crystal droplets are discharged on the mother substrate. At least one or more panel regions may be defined on the mother substrate. 9 201005397 Reference weight of a drop of liquid crystal: It is the predetermined weight of the liquid crystal that is discharged through the nozzle N every time. Liquid crystal reference amount: a predetermined amount of liquid crystal to be applied to each panel region defined on the mother substrate. Liquid crystal amount: liquid liquid droplet amount which is actually applied to each panel region defined on the mother substrate: liquid crystal droplets are expressed by volume. As shown in Figs. 2 and 3, the piston 22 is rotated counterclockwise about the Z axis, and the groove 22a is turned toward the inflow opening 21a. At the same time, the piston 22 slides upwardly from the bottom of the tubular member 21 along the Z-axis by a distance Η. Therefore, the inflow opening 21a is opened, and the liquid crystal flows through the inflow opening 21a and the groove 22a to flow into the liquid crystal suction space S. The suction space S is filled with liquid crystal. These actions of the piston 22 are referred to as suction strokes. As shown in Figs. 4 and 5, the piston 22 is rotated clockwise about the Z axis, and the groove 22a is turned toward the outflow opening 21b. At the same time, the piston 22 slides down the Z-axis to the bottom of the tubular member 21. Therefore, the outflow opening 21b is opened, and the liquid crystal transmission line (not shown) and the nozzle N are discharged to the panel region defined on the mother substrate mp. These actions of the piston 22 are referred to as compression taps. FIG. 6 shows a schematic diagram of the path of coating the liquid crystal amount in each panel area defined by the coating head unit 20 on the mother substrate, as shown in FIGS. 1 to 6 , assuming that the mother __# ni, 2, 3 And 4' and discharge 9 drops of liquid crystal onto each panel & fields 1, 2, 3, and 4. In the actual procedure, more than 4 panel areas may be defined on the mother substrate Mp, and there may be more than 9 drops of liquid. The panels of the MP, such as when the coating head is earlier than 20, are moved by the solid arrow. When the direction is coated, it is very good. 0 through the mouth of the money N row of Wei Wei crystal to the panel _ 丨. The cloth head unit 2G is on the front axis of the Y financial direction, and passes through the 対 J. Then, the coating head unit 20 is horizontally moved in the X-axis direction by a liquid coating head single it 2G and then moved backward in the z-axis direction to discharge 3 : 曰 1 = rear + coating head unit 2G on the X-axis: ^ water u, after the coating head private 2G moves forward in the Y-axis direction to discharge 3 drops of liquid crystal. 9 cycles of containing a total of 9 drops of liquid crystal into the panel area _ on the cycle containing - a suction tap and a - compression tap - _ | coating to -_ plate _ on the reference 'two, 9 _ liquid crystal is equivalent to However, the conventional method is to discharge the secondary suction tap and the compression stroke of the JS through the nozzle N. On the day of the panel, the secret is low, resulting in a limit of 5 °, the amount of liquid crystal coated on the LCD 11 201005397 and then 'Before starting to apply liquid crystal to the other panel area, must be completed on the panel area The amount of liquid crystal is coated. Thus, there is a limit to the movement distance of the coated liquid crystal amount on all the panel regions of the mother substrate. As shown in Fig. 6, there are 16 turning points c on the mother substrate, and the coating head unit 2 turns 9 degrees to the right or left in the direction of the ground, that is, the coating head unit 2 将 moves the direction in these places by Y. The direction of the axis changes to the direction of the x-axis, or vice versa. When the head unit 2〇 reaches the turning point C, 'in order to achieve a stable rotation at the turning point C', the coating head unit 2 needs 2 turns away from the turning point C, and the coating head unit 2 increases the speed. ; 2 = The number of times is twice the number of turning points. The more the panel area is more shameful, the break point C, the longer the amount of liquid crystal is applied to the panel area. SUMMARY OF THE INVENTION One object of the invention is to reduce the time during which the amount of liquid crystal is applied to each panel region defined on the mother substrate. Another object of the present invention is to reduce the distance that the coating head unit moves when the amount of liquid crystal is applied to the mother substrate. Each panel £ unit =: in the method of reducing the panel date a(C)® on the tree head of the coating head 12 201005397 during the coating operation, the method includes the steps of filling the vacuum F day with the liquid crystal The reduction buckle is formed on the bottom wall and the bottom of the piston, and the step of discharging a predetermined number of liquid crystal droplets from the suction space through the nozzle through the suction space. According to another aspect of the present invention, there is provided a method of coating a liquid crystal (LC) amount on a surface defined by a mother wire, the method comprising: a first step, a region of one panel region followed by another a region of a panel region 'discharges at least - drops liquid crystal on the region of the panel region; and a second step repeats the steps defined by the plurality of liquid crystals having the same amount of reference liquid crystal discharged onto the mother substrate On the panel area. According to another aspect of the present invention, there is provided a method of coating a liquid crystal (LC) amount on a panel region defined on a mother substrate, the method comprising: a first step of filling a suction space with a liquid crystal The bottom of the piston is between the wall surface and the bottom of the tubular member; the second step 'selects an area from a panel area in a region of one panel area followed by another area of the panel area, in the discharge direction $ at least - the liquid crystal is in a lined area; and the second step 'in the current discharge direction opposite to the previous discharge direction, and at a predetermined distance from the area of the straight line of the crystallized droplets In the region of the straight line, the second step is repeated until a plurality of liquid crystals equal to the reference liquid crystal amount are discharged onto the panel regions defined on the mother substrate. 13 201005397 According to the present invention, the coating head unit suctions a predetermined amount of liquid crystal, and then sequentially discharges a predetermined number of liquid crystal droplets, thereby reducing the number of times the liquid crystal is sucked. Furthermore, 'the area of the panel area is followed by the area of the other panel area', and the liquid crystal is discharged in the discharge direction to the area of the panel area, which can shorten the movement of the liquid crystal discharged from the coating head unit.

FIG. 8 is a view showing a cylindrical member provided in a coating head and mounted on a cylinder towel. The piston is a straight cross-sectional view of the position of the tapping piston. Fig. 9 is a horizontal sectional view showing the position of the piston provided in the tubular head and the sealing member of the coating head unit at the position of the suction knocking plug. Fig. 10 to Fig. 12 are diagrams showing the change of the position of the piston during compression tapping. 14 201005397 The method of coating liquid in the panel area defined on the mother substrate as shown in Fig. 7 to Fig. 9 includes · Step S1G, filling the suction space with liquid crystal, the two suctions are formed between the bottom of the piston and the wall surface and the bottom of the cylinder; in the second step S20, one area of one panel area is followed by the other panel area In a manner of one area, at least one drop of liquid crystal in a discharge direction of the panel area, 2, 3 and 4 in a straight line on four areas (one area per panel area); and a third step S30' in contrast to the previous discharge Current direction of direction, and in ® Repeating the second step until the region of the previous straight line from which the liquid crystal droplet has been discharged is a predetermined distance from the area of the liquid droplet to be discharged, until the plurality of liquid crystal liquids equal to the reference liquid crystal amount are discharged onto the mother substrate Each panel area 1, 2, 3, and 4. The first step S10 will now be described. As shown in Figures 7 and 8, the piston 22 is rotated counterclockwise about the Z axis so that the groove 22a faces the inflow opening 21a. 22 is slid upward from the bottom of the cylindrical member 21 along the Z-axis by a distance H1. Therefore, the inflow opening 21a is opened, and the liquid crystal flows through the inflow opening D 2la and the groove 22a into the liquid crystal suction space s. The suction space s is filled with a predetermined amount. Liquid crystal. The second step S20 will now be described. In the second step S20, the coating head unit 20 discharges the liquid crystal droplets on one area of one panel area 'and then on one area of another adjacent panel area. 15 201005397 That is, When the coating head unit 20 linearly moves across the panel regions defined on the mother substrate in columns and/or in rows, the coating head unit 20 regionally discharges the liquid crystal droplets onto the panel regions arranged in columns and/or in rows. Figure 7 1A, the piston 22 rotates clockwise around the Z axis, and the groove 22a faces the outflow opening 21b. At the same time, the piston 22 slides down the distance difference (H1 - H2) along the Z axis. As a result, the piston 22 slides down. The liquid crystal m of equal volume is discharged in the shape of a droplet through the groove 22a, the outflow opening 21b, and the nozzle N. As shown in Fig. 11, the piston 22 additionally slides down the distance difference (H2-H3). 22a, the outflow opening 21b, and the nozzle N discharge the liquid crystal amount of the same volume as the movement of the piston 22 in the shape of a droplet. As shown in Fig. 12, the piston 22 additionally slides down the distance difference (H3-〇). The amount of liquid crystal equal to the volume of the piston 22 sliding downward is discharged through the groove 22a, the outflow opening 21b, and the nozzle N. In this way, a predetermined amount of liquid crystal ' is sucked at a time and three drops of liquid crystal are discharged by the nozzle N. The number of times the liquid crystal droplets are discharged is different depending on how many compression taps occur to cause the piston 22 to slide downward. For example, 38 〇mg of liquid crystal can be pumped at a time, and can be discharged 38 times each time 1 mg of liquid crystal is discharged. 16 201005397 In the present embodiment, the coating head unit 20 suctions a predetermined number of liquid crystals a predetermined number of times. That is, after three drops of liquid crystal are discharged through the nozzle N, the first step S10 can be performed three times. Each panel area ου, #) performs the first step of illusion three times, so the number of times of repeating the first step S10 is 12 times. The first-surface S1G can be executed in a repeated manner. The amount of liquid crystal that is transferred to the pure suction space may be smaller than the amount required to be applied to all of the panel regions 丨, 2, 3, and e 4 of the mother substrate. Therefore, a predetermined amount of liquid crystal can be sucked to the suction space a predetermined number of times to discharge a plurality of liquid crystals equal to the amount of the reference liquid crystal on the respective panel regions defined on the mother substrate. Figure 13 is a schematic view showing the first path of the liquid crystal droplets discharged from the coating head unit 2 in accordance with the present invention. For convenience of explanation, four panel regions 丨, 2, 3, and ^ 4 are defined on the mother substrate MP. In fact, two or more panel areas can be defined on the mother substrate MP. There are 9 drops of liquid crystal discharged from the panel areas 1, 2, 3, and 4 of the rice. When the coating head S 2 移动 moves through the panel region i along the solid line in the γ-axis direction, the coating head unit 20 discharges three drops of liquid crystal through the nozzle N on the panel region. Then, the coating head unit 20 is moved along the solid line to the side adjacent to the panel area. 201005397 Plate area 2 When the coating head unit 20 moves through the panel area 2 in the solid line in the Y-axis direction, the coating head unit 20 passes through the nozzle Ν Three drops of liquid crystal are discharged on the panel area 2. Since there is no other panel area on the mother substrate in the γ-axis direction, the coating unit 20 is rotated 90 degrees to the right and moved by a distance L1 along the solid line in the X-axis direction. The third step S30 will now be described. When the coating head unit 20 moves through the panel region 2 in a solid line in the opposite direction, the coating head unit 20 discharges three drops of liquid crystal on the panel region 2 through the nozzle N. Then, when the coating side unit 2G moves through the panel area ^1 along the solid line in the subtraction direction, the coating head unit 20 discharges three drops of liquid crystal on the panel area 1 by spraying, because there is no other panel area on the mother substrate, so Cloth head unit 20. Turn right 90 degrees' and move the distance L1 along the solid line in the X-axis direction. Although the solid line of the coating head unit 20 in the γ-axis direction moves through the panel region 1 ^ the coating head unit 2G is discharged through the squirting discharge to the three-drop panel area]. Then, the solid line of the self-coating solution 7C 20 in the Y-axis direction is moved through the panel area 2, the temple coating head unit 20, and the three-crystals are on the secret area 2. 18 201005397 A total of rows of "drip-carved nucleus fine-breaking _" and 2. Next, the coating head unit 2G turns to the right by % degrees, and along the χ axis u to the panel area 4 the driving unit 2Q is similar to $ and 2 The coating operation is performed on the panel regions 3 and 4. In the first step, each of the 9 liquid crystals is discharged to the panel area, 2, 3, and the heart - 蝮 蝮 row, the method of the invention, the smear unit 2G moves across The panel area _ field is arranged directly, and the panel areas 2 and 3 adjacent to each other are coated with liquid crystal. Therefore, the amount of liquid crystal discharged from the coating head unit 2 can be shortened to the area of each panel area. The amount of pre-grained crystals is reduced to each panel area ==, and the number of times of speed adjustment of the coating head unit near the turning point is lowered, and the first path of coating the liquid crystal m on the mother substrate is lowered. The coating head unit 2 is displayed according to the present invention. 〇 液晶 液晶 液晶 液晶 一步 一步 一步 一步 一步 一步 一步 液晶 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 液晶 液晶 液晶 液晶 液晶 液晶 液晶 液晶The coating solution element 20 is turned to the direction of the subtraction direction.] , ' 19 201005397 Panel area arranged in the X-axis direction The number of panels is greater than the number of panels arranged in the direction of the x-axis, and vice versa. The coating head unit 2G can be threaded across the direction with more dragon zone configurations, and the money is turned to the right by 9G degrees to have less panel configuration.
