Color filter manufacturing method and device thereof

The present invention relates to a method of fabricating a color filter on a glass substrate using an inkjet nozzle and an apparatus therefor.

A method of manufacturing a color filter on a glass substrate using an inkjet nozzle has been proposed (refer to Patent Document 1).

Specifically, at least a transparent coloring material absorbing layer is provided on the transparent substrate, and a region between pixels which should be different colors is a non-colored region having anti-staining property, and pixels adjacent to the same color are adjacent to each other. A color filter is produced by coloring the plurality of pixel portions and the inter-pixel regions which are to be the same color without any gap.

Further, in order to manufacture a color filter on a glass substrate using an inkjet nozzle, the first moving mechanism drives the inkjet head in the first direction, and the color filter is filtered by the second moving mechanism. The mounting table for the sheet substrate is moved in the second direction different from the first direction, and the first moving mechanism is moved by the nozzle along the longitudinal direction of the filter element, and is ejected from the nozzle.

When the method of Patent Document 1 is used, that is, when different screen sizes are processed, the pitch differs depending on the screen size, so that the probability that the inkjet nozzle coincides with the central portion of the pixel becomes low, and the result is low. Therefore, there is a problem that the number of times of scanning of the ink jet head is increased, and the time required for the entire coating is prolonged.

In order to solve such a problem, it is considered that the distance between the ink-jet nozzles is changed by rotating the ink-jet head, but there is a problem that it takes a long time to arrange the change of the steps.

In addition, as a trend of the recent years, the size of the color filter is increased, and the size of the glass substrate on which the color filter is formed is increased. When the color filter or the glass substrate is enlarged, as in Patent Document 1, When the main screen is drawn in a straight line and in parallel, and the entire screen is drawn in such a manner that the pixel portions having the same color are arranged in the same direction as the main scanning direction, the following problems are also caused. That is, it is difficult to spread the entire range of the main scanning so that the color material ejected from the inkjet nozzle is applied to the central portion of the pixel region, and in fact, a part of the pixel region is not coated with the desired color material. As a result, the possibility of manufacturing defective products increases.

In the case of the method of Patent Document 2, in order to process different screen sizes, the pitch differs depending on the screen size, so that the probability that the ink jet nozzle coincides with the central portion of the pixel becomes low, and as a result, there is This causes a problem that the number of times of scanning of the ink jet head increases, and the time required for the entire coating becomes long.

Further, as shown in FIG. 4 of Patent Document 2, the entire screen is drawn in a straight line and in parallel, and the pixels are designed such that the pixel portions having the same color are arranged in the same direction as the main scanning direction. When the color filter or the glass substrate is enlarged, there is a problem in that it is difficult to apply the color material ejected from the ink jet nozzle to the central portion of the pixel region over the entire range of the main scanning. The way to position, in fact, does not apply a portion of the pixel area to the desired color material, resulting in an increased likelihood of manufacturing a defective product.

Furthermore, the two moving mechanisms must be highly accurate, thus causing an increase in overall cost.

The present invention has been developed in view of the above problems, and an object of the invention is to provide a color which can apply a color material ejected from an ink jet nozzle to a central portion of a pixel region regardless of a screen size regardless of an increase in size of a glass substrate.

Hereinafter, embodiments of the color filter manufacturing method and apparatus of the invention of the present application will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view showing an embodiment of a color filter manufacturing apparatus of the invention of the present application.

In the color filter manufacturing apparatus, the adsorption stage 3, the coating holder 4, the camera holder 6, and the like are supported on the susceptor 1.

The adsorption platform 3 adsorbs and holds the glass substrate 2, and in order to achieve the positioning of the glass substrate 2, the adsorption platform 3 is rotationally driven in the θ direction by a driving mechanism and a guiding mechanism (not shown), and the adsorption platform is driven in the Y direction. 3.

The coating holder 4 holds the inkjet head rail 5, and in order to apply a color material to the glass substrate 2, the coating holder 4 is driven in the X direction by a driving mechanism and a guiding mechanism (not shown). Moreover, in order to adjust the relative position with respect to the glass substrate 2, the inkjet head crossbar 5 is driven in the Z direction and the Y direction by the drive mechanism and the guide mechanism not shown.

The camera holder 6 is used to align the cameras 7, 8 and the scanning camera 9. The alignment cameras 7 and 8 are used for alignment of the glass substrate 2, and the scanning camera 9 is for detecting color materials in the pixel region of the glass substrate 2. In order to align and detect pixels, the camera holder 6 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 scanning camera 9 are driven in the Y direction by a drive mechanism and a guide mechanism (not shown).

When the alignment cameras 7 and 8 detect the mark (not shown) of the glass substrate 2, the adsorption platform 3 is rotated according to the mark detection result of the alignment cameras 7 and 8, and/or the adsorption platform 3 is moved in the Y direction. Thereby, the alignment of the glass substrate 2 can be achieved.

Further, X and Y indicate directions orthogonal to each other in order to define a plane parallel to the upper surface of the glass substrate 2 adsorbed and held by the adsorption stage 3, and Z indicates a plane which is defined by X and Y. The direction of the exchange.

Fig. 2 is a schematic view showing the configuration of the ink jet head rail 5.

The ink jet head rail 5 is formed by arranging a plurality of ink jet heads 51, and each of the ink jet heads 51 is formed by arranging a plurality of ink jet nozzles 52. Further, the arrangement of the plurality of ink jet heads 51 is set such that the intervals of the ink jet nozzles 52 in the X direction and the intervals in the Y direction are respectively at a specific interval.

Further, since the inkjet nozzles 52 are arranged obliquely in a specific number of units, the inkjet nozzles 52 are sequentially operated while the coating holder 4 is driven in the X direction, so that they can be linearly arranged in the Y direction. The color material is coated in a state.

The inkjet head rail 5 shown in FIG. 2 is used to apply any one of red (R), green (G), and blue (B) color materials, and may be provided, although not specifically shown. An inkjet crossbar for coating other colored materials.

However, the ink jet head rails 5 for the color materials of red (R), green (G), and blue (B) may be integrally arranged. Of course, it is also possible to provide only an inkjet head crossbar that ejects a color material of one color.

FIG. 8 is a view showing an example of the arrangement of the inkjet nozzles 52.

Fig. 8 shows an ink jet nozzle determined by a nozzle row and a nozzle number, a P-line Y-direction ink-jet nozzle pitch, and an L1-L5-type ink-jet nozzle row-direction interval.

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

Fig. 6 is a flow chart showing the process of manufacturing a color filter.

In the step SP1, the glass substrate 2 is carried into the adsorption stage 3 by a loading robot or the like (not shown), and in step SP2, the positioning of the glass substrate 2 is achieved by a shape regulating mechanism (not shown). Further, in step SP3, the glass substrate 2 is adsorbed by the adsorption platform 3, and thereafter, in step SP4, the camera holder 6 is moved forward, and in step SP5, the glass substrate 2 is detected by the alignment cameras 7, 8. The alignment marks are positioned in the Y direction and the θ direction to achieve alignment of the glass substrate 2, and in step SP6, the camera holder 6 is moved back.

Next, in step SP7, the coating holder 4 is moved forward/returned, and the X coordinate value is output. In step SP8, it is determined whether or not the coating is performed to the terminal based on the X coordinate value.

Further, in addition to the processing, in step SP16, the position information (coordinate value) of the hole of the ink jet nozzle 52 is input, and in step SP17, the position information (coordinate value) of all the pixels on the glass substrate 2 is input, in step In SP18, other parameters are input (for example, an offset value specified in consideration of a discharge speed of a color material, a relative moving speed, a delay of a control system, etc.). Further, in step SP19, the calculation of the data table is performed, and in step SP20, the calculation result is stored in the discharge data table.

Fig. 7 is a view showing an example of a discharge data table, in which the number of coating scans, the coating direction pixel number, the coating direction pixel position, the nozzle row, the coating holder X coordinate value, and the ejection pattern of all the nozzles are set. Further, X0 is the initial movement amount, the Pg is the pixel pitch in the Y direction, the L1 to Ln nozzle row application direction interval, and the m-system coating direction pixel number. The initial movement amount X0 and the pixel pitch Pg are as shown in FIG. 3 shows a state in which only a red (R) color material is applied, and the distance from the first pixel in the X direction is the initial movement amount X0, and the pixel in the X direction is coated with a red (R) color material. The spacing is the pixel pitch Pg.

Further, when it is determined in step SP8 that the coating has not proceeded to the terminal, in step SP13, the X coordinate output value of the coating holder 4 is compared with the discharge data table, and in step SP14, the X coordinate is determined. Whether the value coincides with the discharge data, and if the X coordinate value coincides with the discharge data, the ink ejection nozzle 52 is operated to eject the ink in step SP15.

Fig. 5 is a schematic view showing the above processing.

In order to eject, the inkjet nozzle 52 that is the target pixel region and the X coordinate value are operated, and the ink is applied to the pixel region to be coated without operating the other inkjet nozzles 52. Specifically, the ink jet nozzle 52 is coated with the color material while moving relative to the glass substrate 2, and thus the offset value specified by the discharge speed of the color material, the relative moving speed, the delay of the control system, and the like is considered. The ink jet nozzle 52 for ejecting is controlled in consideration of the above offset value.

4 is a schematic view for explaining control of the ink jet nozzle 52 in the Y direction. Again, this process is not shown in the flowchart, but is shown in FIG.

The inkjet nozzle 52 covering at least a part of the Y coordinate range is not operated, and the Y coordinate range indicates the width of the black matrix extending in the X direction of the glass substrate 2, and enters the entire pixel region to be coated for ejection. The inkjet nozzle 52 of the Y coordinate range operates to apply ink to the pixel region to be coated.

Further, when it is determined in step SP14 that the X coordinate value does not coincide with the ejection data, or when the processing of step SP15 is performed, the processing of step SP7 is performed again.

Moreover, when it is determined in step SP8 that the application is performed until the terminal is reached, it is determined in step SP9 whether or not coating is performed a certain number of times.

When it is determined in step SP9 that the number of times of application has not reached the specific number of times, in step 12, the head rail 5 is moved in the Y direction, and the processing of step SP7 is performed again. Further, the moving distance in the Y direction may be, for example, a distance determined by the number of liquid droplets of the color material to be applied to one pixel region, or may be an integer of the pixel pitch of the distance plus the Y direction. The distance obtained after the double. In the latter case, the ink jet nozzle ejects ink to different pixels, so that even if the size of the landing mark differs for each ink jet nozzle, the whole can be averaged. Here, if the application area of the inkjet head rail 5 is set larger than the coating area of the glass substrate 2, even if the inkjet head rail 5 is moved as in the latter, the color material can be smoothly applied to all the pixels. .

When it is determined in step SP9 that the application has been performed for a certain number of times, the coating process is terminated in step SP10, and in step SP11, the glass substrate 2 is carried out by a carry-out robot or the like (not shown). End a series of processing.

When the above is summarized, after the glass substrate 2 is carried into the adsorption stage 3, the camera holder 6 is moved forward to detect the alignment mark of the glass substrate 2, and the adsorption stage 3 is operated according to the detection result, thereby realizing the glass substrate. 2 alignment. Thereafter, the camera holder 6 is moved back.

Next, the coating holder 4 is moved forward to perform the first coating.

Thereafter, the coating holder 4 is moved backward in a state of being slightly moved in the Y direction, thereby performing the first return coating, during which the camera holder 6 is moved forward, and the glass substrate 2 is moved by the scanning camera 9. The inspection of the landing marks of the color material in the pixel area, and thereafter, the camera holder 6 is moved back.

Thereafter, the coating holder 4 is moved in a state of being slightly moved in the Y direction, thereby performing the second forward coating.

Thereafter, the coating holder 4 is moved back in a state of being slightly moved in the Y direction, whereby the second return coating is performed.

Thereafter, the adsorption and holding of the glass substrate 2 are stopped, and the glass substrate 2 is carried out from the adsorption stage 3. Thereafter, by performing the above-described series of processes in reverse, a desired number of color filters can be produced.

In other words, when the color material is applied once, the color material is attached at intervals equal to the interval between the ink jet nozzles 52, and thus the state in which the color material is continuously applied is not formed.

However, in the case of performing the above-described series of processes, the position in the Y direction is slightly changed and applied, and finally, as shown in FIG. 3, the pixel region corresponding to the black matrix 21 formed on the glass substrate 2 can be used. Within 22, the color material 23 is continuously applied.

As can be understood from the above description, the timing of the operation of the inkjet nozzles 52 can be controlled while the inkjet head rails 5 are relatively moved. Therefore, the pixel regions 22 corresponding to the black matrix 21 formed on the glass substrate 2 can be used. Reliably coating colored materials.

For example, when the distance between 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 period of the inkjet nozzle 52 is 10 kHz or more, In the case of coating a color material at a pitch of 300 μm{(70 μm+30 μm)×3}, the relative scanning speed is 210 mm/s, whereby all the inkjet nozzles 52 can be driven at 10 kHz for color material coating. cloth. Moreover, when the pixel size is changed, it can be easily processed by adjusting the scanning speed.

Further, the pixel size in the direction orthogonal to the moving direction of the ink jet head rail 5 is 200 to 300 μm, and a sufficiently large range can be secured for the liquid droplets of the color material ejected from the ink jet nozzle 52. Further, the pixel size of the relative movement direction of the ink jet head rail 5 is 70 to 100 μm, and the range corresponding to the droplet of the color material ejected from the ink jet nozzle 52 becomes small, and the ink jet nozzle is controlled with high precision. The timing of 52 actions. As a result, the color material can be reliably applied in the pixel region 22 corresponding to the black matrix 21 formed on the glass substrate 2.

Although the embodiment in which the coating holder 4 is moved in the X direction with respect to the adsorption stage 2 has been described above, the application holder 4 may be fixed to move the adsorption stage 3.

Further, it is preferable that one side of the adsorption stage 3 is set larger than the long side of the glass substrate 2, and the glass substrate 2 can be reliably adsorbed to the adsorption stage 3 regardless of the state in which the glass substrate 2 is carried.

In the above embodiment, the number N of the ink jet nozzles 52 opposed to one pixel, the number of remaining nozzles n, the amount of droplets per droplet of the ink jet nozzle 52, and the relative movement are preferably. The number M of ejections in the pixel in the direction and the amount V of the color material applied to one pixel have a relationship of several 1.

Further explanation.

Fig. 9 is a view schematically showing the relationship between a pixel region and a liquid droplet.

In the figure, a and b denote the pixel size, c and d denote the coated area in the pixel, and M denotes the number of droplets in the relative moving direction (the number of droplets in the relative moving direction), denoted by N and 1 The number of inkjet nozzles 52 opposite the pixel (the number of opposing nozzles, or the number of opposing nozzle droplets).

Further, the total number of the inkjet nozzles 52 corresponding to one pixel is one more than the number N, and the difference between the total number and the number N is the number of remaining nozzles n. Therefore, the number i of the combinations of the inkjet nozzles 52 for applying a color material to one pixel satisfies i = _N C _N-n .

Further, by changing the combination of the ink jet nozzles 52 for applying the color material to the pixels (selected ejection state), the coating in the coating direction can be unevenly dispersed, and the coating unevenness can be made inconspicuous.

Example

The coating test was carried out under the following conditions, that is, the nozzle width was 25400 μm, the nozzle resolution was 1440 dpi, the nozzle pitch P was 25400/1440=17.6 μm, the pixel size was a=300 μm, b=100 μm, The coating area size is c=220 μm, d=20 μm, the number of counter nozzles is N=c/P=220/17.6≒12, the number of droplets M in the relative movement direction is 1, and the amount of coating in the pixel (in the pixel) The filling amount) is 300 pl, and the amount Q per droplet of the droplet is 40 pl.

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

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

Therefore, by applying the color material by using the ink jet nozzle 52 (selective ejection state) of a combination of 495 or less (for example, a combination of 50 groups), uneven coating can be dispersed, and uneven coating can be performed. Not obvious.
