Description

  The present invention relates to a method and an apparatus for manufacturing a color filter on a glass substrate using an inkjet nozzle.

  Conventionally, a method of manufacturing a color filter on a glass substrate using an inkjet nozzle has been proposed (see Patent Document 1).

  Specifically, at least a transparent colorant-receiving layer is provided on a transparent substrate, a region that should be between pixels of different colors is a non-colored region having color repellent properties, and pixels that are to have the same color are In adjacent locations, a color filter is manufactured by coloring the plurality of pixel portions that should have the same color, including the inter-pixel regions, without any discontinuities.

  In addition, by adopting a method in which the entire screen is drawn by performing main scanning in a straight line in parallel, the pixel arrangement is designed so that pixel portions to be colored in the same color are aligned in the same direction as the main scanning direction. Full-surface drawing is achieved by linear main scanning along the columns.

Further, in order to manufacture a color filter on a glass substrate using an inkjet nozzle, the inkjet head is driven in the first direction by the first moving mechanism, and the mounting table for mounting the color filter substrate by the second moving mechanism. Are moved in a second direction different from the first direction, and the first moving mechanism is moved so that the nozzles follow the column of filter elements, and ink droplets ejected from the nozzles overlap in the filter elements. There has been proposed a method of controlling the discharge cycle and the first and second moving mechanisms with such a discharge cycle and the moving speed of the inkjet head (see Patent Document 2).
Japanese Patent Laid-Open No. 9-68611 JP-A-10-260307

  In the case of adopting the method of Patent Document 1, when dealing with each of different screen sizes, since the pitch is different for each screen size, the probability that the inkjet nozzle and the central portion of the pixel match is low, As a result, there is a problem that the number of scans by the ink jet head increases and the time required for coating as a whole becomes long.

  In order to solve such a problem, it is conceivable to change the pitch of the ink jet nozzles by rotating the ink jet head, but there is a problem that it takes a lot of time to change the setup.

  Further, as a recent trend, there is an increase in the size of the color filter and an increase in the size of the glass substrate on which the color filter is formed. When the color filter and the glass substrate are increased in size in this way, When a method of drawing in parallel with main scanning in a straight line is adopted and the pixel arrangement is designed so that the pixel portions to be colored in the same color are aligned in the same direction as the main scanning direction, the entire range of main scanning It is difficult to position the color material discharged from the inkjet nozzle so that it is applied to the center of the pixel area. In fact, a desired color material is applied to a part of the pixel area. As a result, there is a problem that the possibility of producing a defective product increases.

  In the case of adopting the method of Patent Document 2, since the pitch is different for each screen size in order to deal with each of the different screen sizes, the probability that the inkjet nozzle and the central portion of the pixel coincide with each other decreases. As a result, there is a problem that the number of scans by the ink jet head increases, and the time required for coating as a whole becomes long.

  Further, as shown in FIG. 4 of Patent Document 2, the entire screen is drawn in a straight line parallel to the main scan, and the pixel array is arranged so that the pixel portions to be colored in the same color are aligned in the same direction as the main scan direction. Therefore, when the color filter and the glass substrate are enlarged, positioning is performed so that the color material discharged from the inkjet nozzle is applied to the center of the pixel area over the entire main scanning range. In reality, there is a problem that a desired color material is not applied to a part of the pixel regions, and as a result, there is a high possibility that a defective product is manufactured.

  Furthermore, since high accuracy is required for both moving mechanisms, the cost increases as a whole.

  The present invention has been made in view of the above problems, and applies a color material ejected from an inkjet nozzle to the center of a pixel region regardless of the size of a glass substrate regardless of the screen size.

  Embodiments of a color filter manufacturing method and apparatus according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view showing an embodiment of a color filter manufacturing apparatus according to the present invention.

  This color filter manufacturing apparatus supports a suction table 3, a coating gantry 4, a camera gantry 6 and the like on a machine base 1.

  The suction table 3 holds the glass substrate 2 by suction. In order to achieve positioning of the glass substrate 2, the suction table 3 is rotated in the θ direction and driven in the Y direction by a drive mechanism and a guide mechanism (not shown). Is done.

  The application gantry 4 holds the inkjet head bar 5 and is driven in the X direction by a drive mechanism and a guide mechanism (not shown) in order to apply a color material to the glass substrate 2. Further, in order to adjust the relative position with respect to the glass substrate 2, the ink jet head bar 5 is driven in the Z direction and the Y direction by a drive mechanism and a guide mechanism (not shown).

  The camera gantry 6 holds alignment cameras 7 and 8 for alignment of the glass substrate 2 and a scan camera 9 for detecting landing marks of the color material in the pixel region of the glass substrate 2. For pixel detection, it is driven in the X direction by a drive mechanism and a guide mechanism (not shown). Further, the alignment cameras 7 and 8 and the scan camera 9 are driven in the Y direction by a drive mechanism and a guide mechanism (not shown).

  The alignment cameras 7 and 8 detect marks (not shown) on the glass substrate 2, and the suction table 3 is rotated and / or moved in the Y direction based on the mark detection results by the alignment cameras 7 and 8. Thus, alignment of the glass substrate 2 can be achieved.

  X and Y represent directions orthogonal to each other set to define a plane parallel to the upper surface of the glass substrate 2 held by suction by the suction table 3, and Z represents a plane defined by X and Y. An orthogonal direction is shown.

  FIG. 2 is a schematic view showing the configuration of the inkjet head bar 5.

  The inkjet head bar 5 is formed by aligning a plurality of inkjet heads 51, and each inkjet head 51 is formed by aligning a plurality of inkjet nozzles 52. The alignment of the plurality of inkjet heads 51 is set such that the intervals in the X direction and the intervals in the Y direction of all the inkjet nozzles 52 are respectively predetermined intervals.

  Since the inkjet nozzles 52 are arranged in an oblique direction with a predetermined number as a unit, the inkjet nozzles 52 are sequentially operated while driving the coating gantry 4 in the X direction, thereby linearly aligning in the Y direction. In this state, the color material can be applied.

  The ink jet head bar 5 shown in FIG. 2 is for applying any one of red (R), green (G), and blue (B) color materials. An inkjet head bar for applying the material is also provided.

  However, the inkjet head bars 5 for the red (R), green (G), and blue (B) color materials may be integrally arranged. Of course, only an inkjet head bar that discharges one color material may be provided.

  FIG. 8 is a diagram illustrating an example of the arrangement of the inkjet nozzles 52.

  FIG. 8 shows inkjet nozzles determined by nozzle rows and nozzle numbers, where P is an inkjet nozzle pitch in the Y direction, and L1 to L5 are intervals in the inkjet nozzle row application direction.

  Next, the operation of the color filter manufacturing apparatus having the above configuration will be described.

  FIG. 6 is a flowchart for explaining the color filter manufacturing process.

  In step SP1, after the glass substrate 2 is carried into the suction table 3 by a carrying robot (not shown) or the like, in step SP2, the rough positioning of the glass substrate 2 is achieved by outer shape regulating means (not shown). In step SP3, the glass substrate 2 is sucked by the suction table 3, and then the camera gantry 6 is moved forward in step SP4. In step SP5, the alignment mark of the glass substrate 2 is detected by the alignment cameras 7 and 8. The alignment of the glass substrate 2 is achieved by positioning in the Y direction and the θ direction, and the camera gantry 6 is moved back in step SP6.

  Next, in step SP7, the application gantry 4 is moved forward / backward, and the X coordinate value is output. In step SP8, it is determined whether or not the application has been performed to the end based on the X coordinate value.

  Separately from this process, in step SP16, the position information (coordinate values) of the holes of the inkjet nozzle 52 is input, and in step SP17, the position information (coordinate values) of all the pixels on the glass substrate 2 is input. In step SP18, other parameters (for example, an offset value determined in consideration of the discharge speed of the color material, the relative movement speed, the delay of the control system, etc.) are input. In step SP19, the data table is calculated, and in step SP20, the calculation result is stored in the discharge data table.

  FIG. 7 is a diagram showing an example of a discharge data table, in which the number of application scans, application direction pixel numbers, application direction pixel positions, nozzle rows, application gantry X coordinate values, and discharge patterns for all nozzles are set. X0 is an initial movement amount, Pg is a pixel pitch in the Y direction, L1 to Ln are nozzle row application direction intervals, and m is a pixel number in the application direction. The initial movement amount X0 and the pixel pitch Pg are shown in FIG. FIG. 3 shows a state in which only the red (R) color material is applied, the distance to the first pixel in the X direction is the initial movement amount X0, and the red (R) color material in the X direction. The pixel pitch Pg is an interval between pixels to which is applied.

  If it is determined in step SP8 that the application has not been performed to the end, in step SP13, the X coordinate output value of the application gantry 4 and the discharge data table are compared, and in step SP14, the X coordinate value is determined. In step SP15, the ink jet nozzle 52 is operated to eject ink.

  FIG. 5 is a schematic diagram for explaining the above processing.

  Ink is applied to the pixel area to be applied by operating the inkjet nozzle 52 whose X coordinate value matches the pixel area to be applied for ejection and not operating the other inkjet nozzles 52. Specifically, since the color material is applied while moving the inkjet nozzle 52 relative to the glass substrate 2, the discharge speed of the color material, the relative movement speed, the delay of the control system, etc. are taken into consideration. The inkjet nozzle 52 for ejection is controlled in consideration of the offset value determined.

FIG. 4 is a schematic diagram for explaining the control of the inkjet nozzle 52 in the Y direction. This process is not shown in the flowchart, but is shown in FIG.
An inkjet nozzle that prevents the inkjet nozzle 52 that at least partly covers the Y coordinate range representing the width of the black matrix extending in the X direction on the glass substrate 2 and that entirely enters the Y coordinate range of the pixel area to be coated. By operating 52 for ejection, ink is applied to the pixel area to be applied.

  If it is determined in step SP14 that the X coordinate value does not match the ejection data, or if the process of step SP15 is performed, the process of step SP7 is performed again.

  If it is determined in step SP8 that the application has been performed to the end, it is determined in step SP9 whether or not a predetermined number of times of application has been performed.

  If it is determined in step SP9 that the number of times of application has not reached the predetermined number, in step 12, the inkjet head bar 5 is moved in the Y direction, and the process of step SP7 is performed again. The moving distance in the Y direction may be a distance determined by the number of droplets of color material to be applied to one pixel area, for example, but an integral multiple of the pixel pitch in the Y direction is set to this distance. The added distance may be used. In the latter case, since the ink jet nozzles eject ink to different pixels, even if there is a variation in the size of the landing mark for each ink jet nozzle, it can be averaged as a whole. Here, if the application area of the inkjet head bar 5 is set larger than the application area of the glass substrate 2, even if the inkjet head bar 5 is moved as in the latter case, the color material is applied to all the pixels without any problem. be able to.

  If it is determined in step SP9 that the coating has been performed a predetermined number of times, the coating process is terminated in step SP10. The process ends.

In summary,
After the glass substrate 2 is carried into the suction table 3, the camera gantry 6 is moved forward to detect the mark on the glass substrate 2, and the suction table 3 is operated according to the detection result, whereby the glass substrate 2 is moved. Achieve the alignment. Thereafter, the camera gantry 6 is moved back.

  Next, the application gantry 4 is moved forward to perform the first outward application.

  Thereafter, the coating gantry 4 is moved backward in the Y direction to perform the first return coating, and during this time, the camera gantry 6 is moved forward and the pixel region of the glass substrate 2 is scanned by the scan camera 9. The landing marks of the inner color material are inspected, and then the camera gantry 6 is moved back.

  Thereafter, the second outward coating is performed by moving the coating gantry 4 in a state where the coating gantry 4 is slightly moved in the Y direction.

  Thereafter, the second return coating is performed by moving the coating gantry 4 backward in a state of being slightly moved in the Y direction.

  Thereafter, the suction holding of the glass substrate 2 is stopped, and the glass substrate 2 is unloaded from the suction table 3. Thereafter, a desired number of color filters can be manufactured by repeatedly performing the series of processes described above.

  That is, when the color material is applied once, the color material adheres at an interval equal to the interval between the ink jet nozzles 52, so that the color material is not continuously applied.

  However, in the case where the above-described series of processing is performed, since the coating is performed by slightly changing the position in the Y direction, the film is finally formed on the glass substrate 2 as shown in FIG. The color material 23 can be continuously applied in the corresponding pixel region 22 of the black matrix 21.

  As can be seen from the above description, the operation timing of the ink jet nozzle 52 may be controlled while the ink jet head bar 5 is relatively moved, so that the corresponding pixel of the black matrix 21 formed on the glass substrate 2 is used. The color material can be reliably applied in the region 22.

For example, when the pitch of the inkjet nozzles 52 is 80 μm, the pixel size is 70 to 100 μm × 200 to 300 μm, the width of the black matrix is 30 μm, and the ejection cycle of the inkjet nozzles 52 is 10 kHz or more, 300 μm { When a color material is applied at a pitch of (70 μm + 30 μm) × 3}, the color material can be applied by driving all the inkjet nozzles 52 at 10 kHz by setting the relative scanning speed to 210 mm / s. . Further, when the pixel size is changed, it can be easily dealt with by adjusting the scanning speed.
Furthermore, the pixel size in the direction orthogonal to the relative movement direction of the inkjet head bar 5 is 200 to 300 μm, and a sufficiently large margin can be secured for the droplets of the color material ejected from the inkjet nozzle 52. it can. Further, the pixel size in the relative movement direction of the inkjet head bar 5 is 70 to 100 μm, and the margin for the color material droplets ejected from the inkjet nozzles 52 is small, but the timing for operating the inkjet nozzles 52 is accurate. Control well. As a result, the color material can be reliably applied in the corresponding pixel region 22 of the black matrix 21 formed on the glass substrate 2.

  The embodiment in which the application gantry 4 is moved in the X direction with respect to the suction table 2 has been described above. However, the application gantry 4 can be fixed and the suction table 3 can be moved. is there.

  Moreover, it is preferable to set one side of the suction table 3 to be larger than the long side of the glass substrate 2, and the glass substrate 2 can be reliably sucked to the suction table 3 regardless of the state of loading of the glass substrate 2. .

  In the above embodiment, the number N of the inkjet nozzles 52 facing one pixel, the number of surplus nozzles n, the amount Q per droplet of the inkjet nozzles 52, the number of ejections M within the pixel in the relative movement direction, In addition, it is preferable that the amount V of the color material applied to one pixel has a relationship of Formula 1.

  Further explanation will be given.

  FIG. 9 schematically shows the relationship between the pixel region and the droplet.

In the figure, the pixel internal dimensions are represented by a and b, the intra-pixel application areas are represented by c and d, the number of droplets in the relative movement direction (the number of droplets in the relative movement direction) is represented by M, and one pixel. The number of ink jet nozzles 52 (the number of opposed nozzles or the number of opposed nozzle droplets) that is opposed to is represented by N.
Further, the total number of inkjet nozzles 52 corresponding to one pixel is one or more more than the number N, and the difference between the total number and the number N is the surplus nozzle number n. Therefore, the number i of the combination of the ink jet nozzles 52 for applying a color material in one _pixel, becomes i = _{N C N-n.}

Then, by changing the combination of the inkjet nozzles 52 used for applying the color material to the pixels (the ejection state is selected), the application unevenness in the application direction can be dispersed, and the application unevenness is less noticeable. can do.
Example Nozzle width 25400 μm, nozzle resolution 1440 dpi, nozzle pitch P 25400/1440 = 17.6 μm, pixel size a = 300 μm, b = 100 μm, application area size c = 220 μm, d = 20 μm, counter nozzle The number is N = c / P = 220 / 17.6≈12, the number M of droplets in the relative movement direction is 1, the coating amount in the pixel (filling amount in the pixel) V is 300 pl, and the amount Q per droplet is Q. A coating test was performed under the condition of 40 pl.

  Under this condition, the number of surplus nozzles n satisfying the application amount in the pixel can be obtained by substituting a specific numerical value into Equation 1, and the number of surplus nozzles n is 4 or less.

  As a result, the number i of combinations of the inkjet nozzles 52 is 495.

  Therefore, application unevenness can be dispersed by applying a color material (selecting a discharge state) using 495 or less combinations (for example, 50 combinations) of inkjet nozzles 52. Unevenness could be made inconspicuous.
