Description

  The present invention provides an information display for displaying information such as an image by moving a display medium configured as a particle group sealed in a plurality of cells partitioned by a partition wall between two substrates, at least one of which is transparent. A particle group serving as a display medium is arranged in a display area corresponding to an information display panel provided on a mother substrate for manufacturing a display panel through a mask having an opening having a size corresponding to the display area. The present invention relates to an information display panel manufacturing apparatus and a manufacturing method used for the purpose.

  As an information display device that replaces a liquid crystal display device (LCD), a plurality of cells partitioned by a partition wall are formed between at least one transparent substrate, and particles having optical reflectivity are included in the cells. An information display panel that encloses a particle group as a display medium and displays information such as an image by moving the display medium is known. In addition, charged particles, conductive particles, charge injection particles, and the like have been proposed as the particles constituting the particle group serving as the display medium. Among these, an information display panel that performs display by a method of moving charged particles has a display memory property, and thus is expected as electronic paper.

  As a method for manufacturing the above-described information display panel, a method using a mask has been proposed (for example, see Patent Document 1). In this method, on the substrate constituting the information display panel, a conductive mask is provided as a dummy on a portion of the particle group constituting the display medium that is not required to be disposed (a portion other than the partition forming portion when the partition is formed). By disposing a group of particles as a display medium from a nozzle disposed above the substrate and the mask with a spacer in between, a predetermined amount of the particle group is separated from the substrate (if a partition is formed, the partition is partitioned by the partition Placed in the cell).

The mother board 32 carried into the board 31 is arranged in the mother board lifting / lowering part 45. Further, a guide 46 is provided on the side facing the stage 36 around the mask alignment hole 40 in order to make the mask alignment pin 41 enter smoothly.

  The setting of the mother substrate 32 and the mask 33 on the stage 36 in the method for manufacturing the information display panel of the present invention will be described below in accordance with the example shown in FIGS.

  First, as shown in FIG. 7A, the mother substrate alignment pin 38 and the mother substrate lifting part 45 are set to the stage 36 so as to protrude from the stage 36 to a predetermined height. In this state, the mother substrate 32 aligned outside the tank 31 is disposed on the mother substrate lifting / lowering part 45. Next, as shown in FIG. 7B, the mother substrate raising / lowering portion 45 is lowered, and the mother substrate 32 is placed in the tapered tip portions 37 of the two mother substrate alignment pins 38 protruding from the stage 36. The mother substrate 32 is positioned on the stage 36 by lowering the mother substrate alignment pin 38 below the surface of the stage 36, and the mother substrate 32 is placed on the stage 36 by the mother substrate suction portion 44. Adsorb and fix to. At this time, the mother substrate 32 is self-aligned by the tapered tip portions 37 of the two mother substrate alignment pins 38, and the mother substrate 32 can be disposed at a predetermined position of the stage 36.

  Next, as shown in FIG. 7C, the mask alignment pin 41 is set in a state of protruding from the stage 36 to a predetermined height. In this state, the mask 33 is mounted on the mask alignment pin 41 by inserting the mask alignment pin 41 into the mask alignment hole 40 of the mask 33 via the guide 46. Next, as shown in FIG. 7D, the mask alignment pin 41 is lowered to position the mask 33 on the mother substrate 32, and the mask 33 is moved to the frame portion 42 of the stage 36 by the mask suction portion 43. The mask 33 is brought into contact with the mother substrate 32 while being fixed by suction. In the state shown in FIG. 7D, the particle group as the display medium is arranged in the display area 34 of the information display panel on the mother substrate 32. At this time, the mask alignment pin 41 can be easily attached to the mask alignment hole 40 by the action of the tapered tip portion 39 of the mask alignment pin 41 and the guide 46, and the mask alignment pin 41 is attached to the mask alignment hole 40. The insertion of the mask 33 with respect to the stage 36 and the mother substrate 32 can be achieved.

  In the example shown in FIGS. 7A to 7D, the mother substrate 32 can be positioned and set with respect to the stage 36 by the action of the mother substrate lifting portion 45 and the tapered tip of the mother substrate alignment pin 38. The mask 33 can be positioned and set with respect to the stage 36 by the action of the mask alignment pin 41 and the mask alignment hole 40. As a result, the positioning of the opening 35 of the mask 33 with respect to the display area 34 of the information display panel on the mother substrate 32 can be easily achieved.

  FIGS. 8A and 8B are views for explaining the relationship between the mother substrate and the mask, the mother substrate alignment pin and the mask alignment pin, and the action of the tapered tip portion of the mother substrate alignment pin, respectively. In the present invention described above, the reason why each of the tip portion 37 of the mother substrate alignment pin 38 and the tip portion 39 of the mask alignment pin 41 is tapered is as follows. That is, when the tip portion 37 of the mother substrate alignment pin 38 and the tip portion 39 of the mask alignment pin 41 are not tapered, the mother substrate 32 and the mask 33 are displaced as shown in FIG. In some cases, the mother substrate 32 and the mask 33 may not be correctly mounted on the substrate alignment pins 38 and the mask alignment pins 41. On the other hand, when the tip 37 of the mother board alignment pin 38 has a tapered shape, as shown in an example of FIG. Can do. The tapered tip portion 39 of the mask alignment pin 41 has the same function. Therefore, there is an advantage that accuracy is not so required for carrying in the mother substrate 32 and the mask 33.

  In the present invention, the number of the mother substrate alignment pins 38 is set to at least two. The mother substrate 32 is supported by the mother substrate lifting and lowering portion 45, and the mother substrate alignment pin 38 is simply the mother substrate 32. In this positioning, since it is only necessary to eliminate the final misalignment of the mother substrate 32 that is carried in after being aligned from the outside and positioned to some extent, it is sufficient to have at least two. It is. The number of the mask alignment pins 41 is at least two because the mask 33 is supported and positioned by inserting the mask alignment pins 41 into the mask alignment holes 40 of the mask 33. This is because two is sufficient.

  As described above, after the particle group as the display medium is arranged using the mask 33 in the display area 34 of the information display panel on the mother substrate 32, the suction by the mask suction unit 43 is released, and the mask 33 And the contact with the mother board 32 are released. Next, after the mask alignment pin 41 is raised and the mask 33 is retracted above the mother substrate 32, the suction by the mother substrate suction portion 44 is released. Thereafter, the mother substrate raising / lowering unit 45 is raised to raise the mother substrate 32, and the mother substrate 32 is carried out of the tank 31 by a loading / unloading means such as a magic hand (not shown) to form a display medium. The arrangement process is completed.

  When using a cleaning mechanism for removing particles deposited on the surface of the mask 33, it is preferable to provide the mask alignment hole 40 in an area that does not interfere with the cleaning mechanism. Further, when an alignment mechanism such as the mother substrate alignment pin 38 and the mask alignment pin 41 is installed in the cleaning region, it is preferable to lower each alignment pin during cleaning. Further, the mask 33 is preferably fixed with a movement allowance of 0 to 10 mm in the vertical and horizontal directions so as not to disturb the mask alignment.
