no. 1 Embodiment approach

[0083] [constitute]

[0084] First, refer to figure 1 and figure 2 The structure of the adhesive coating apparatus 1 (henceforth this apparatus) of this embodiment is demonstrated. The workpiece|work S used as a bonding object is made into the workpiece|work S which comprises a display apparatus. For example, a liquid crystal module and a cover panel constituting a liquid crystal display device can be used as the workpiece S. As shown in FIG.

[0085] The workpiece S on the adhesive coating device 1 is supported on the support part J with the coating surface directed upward. The support unit J has a stage K on which the workpiece S is placed. The stage K is provided so as to be able to reciprocate in the horizontal direction by a drive mechanism M. As shown in FIG. As the driving mechanism M, for example, a ball screw rotated by a driving source is considered. However, any device may be used as long as it can reciprocate the workpiece S in the horizontal direction. The...

no. 2 Embodiment approach

[0143] Except as stated Figure 1 to Figure 5 In addition, refer to Figure 6 ~ Figure 10 This embodiment will be described.

[0144] [artifact]

[0145] This embodiment is an apparatus for manufacturing a member for a display device that manufactures a laminate of members for a display device. Members for display devices include not only members having a display function, such as members formed by laminating a display panel and a cover panel, but also those that do not have a display function, such as members formed by laminating a cover panel and a touch panel. Functional components. That is, workpieces to be laminated include various workpieces such as display panels, touch panels, cover panels, backlights, or light guide plates thereof. Together, they constitute a member for a display device.

[0146] There are various types of display panels, such as liquid crystal panels and organic EL panels, and their shapes are also various. Here, we will use it as an example. ...

Abstract

The present invention provides an adhesive coating device and a coating method thereof, and a manufacturing device and a manufacturing method of a member for a display device, which can suppress a partial change in the temporarily hardened state of an adhesive coated on a workpiece, Thereby, deterioration of bonding quality can be prevented. An adhesive coating device (1) that applies an adhesive (R) hardened by irradiation with UV light to a work (S) that is a cover panel constituting a display device, and has: an application unit (10), Coating the adhesive (R) on the workpiece (S) while moving relative to the workpiece (S); , UV light is irradiated so that the irradiation amount per unit area of ​​the adhesive (R) coated on the workpiece (S) becomes constant.

Description

technical field [0001] The present invention relates to an adhesive coating technology and a manufacturing technology of a member for a display device which are improvements in the technology of applying an adhesive to a pair of workpieces constituting a display device, for example, in order to bond them together technology. Background technique [0002] Generally speaking, a flat panel display device (flat panel display) represented by a liquid crystal display or an organic electroluminescence (EL) display is formed by combining a display module and a touch panel for operation. , and a protective panel (cover panel) for protecting the surface, etc. are laminated and constituted. These display modules, touch panels, cover panels, and the like (hereinafter referred to as work) are incorporated into the frame of the flat panel display. The display module includes a plurality of members such as a display panel including a polarizing plate, a drive circuit, and a printed circu...
