Description

TECHNICAL FIELD

[0001] The present application relates to an adhesive layer forming apparatus and a display device manufacturing system including the same, and more particularly, to an adhesive layer forming apparatus capable of manufacturing a display device and a display device manufacturing system including the same. BACKGROUND

[0002] With the development of display technology, various types of display devices have been developed. Display devices are classified into liquid crystal displays (LCDs), organic light emitting diode displays (OLEDs), plasma display panels (PDPs), micro LED displays, etc. according to a light emitting method.

[0003] Display devices are composed of different functional panels, and are attached by interposing an adhesive layer between the panels. The adhesive layer is classified into an optical clear adhesive (OCA) and an optical clear resin (OCR) which is formed by applying and curing a liquid adhesive according to the type.

[0004] Many processes are performed on the manufacturing process of a display device, and each process is sequentially performed in a series of order. In the process equipment of a display device, as a method of improving product yield, a scheme of constituting a production line performing the same function in two lines (dual line) or more, or a scheme of configuring a series of interlocking production lines such as a pretreatment process and a main process as an integrated production line in each equipment is applied.

[0005] The problem of the existing display device manufacturing system is that different processes are performed separately, and it is necessary to move between process areas, and the discontinuous process reduces process efficiency.

[0006] In addition, the existing display device manufacturing system includes an adhesive layer forming part consisting of one head and one UV curing machine to spray and form an adhesive layer in a single process, and thus when an adhesive layer of a desired shape is formed, the adhesive layer forming process and the UV curing process must be separately performed in one adhesive layer forming part, and since the waiting time thereof causes the adhesive layer forming process of other panels to be delayed, there is a problem of inhibiting productivity and increasing manufacturing costs.

More specifically, the control portion 40 can control to generate a first image for forming a first adhesive layer R1 on the first panel P1, and then generate a second image so that a second adhesive layer R2 is formed on the first panel P1. It can be controlled to sequentially generate a third image so that a third adhesive layer R3 is formed on the first panel P1.
