Description

Display manufacturing device {DEVICE FOR MANUFACTURING DISPLAY}

The present invention relates to a display manufacturing apparatus, and relates to a display manufacturing apparatus capable of automatically cutting a display panel in which FSA and FSM are laminated or bonded according to a size to be applied.

Organic Light-Emitting Diode (OLED), which has recently been in the limelight as a display device for various purposes, has a much faster reaction speed than a thin film transistor liquid crystal display (TFT LCD), and can emit light by itself without a separate backlight unit, so it has a thickness and weight compared to conventional LCDs. can be reduced by one-third, and it is positioned as a next-generation display boasting a wide viewing angle and low power consumption structure.

These OLEDs are divided into AM method (active) and PM method (passive). Compared to OLED, PMOLED has a lower manufacturing cost and has limitations in power consumption, lifespan, and resolution. Since OLED has a TFT and a capacitor for each pixel and is excellent in terms of power consumption, lifespan, and resolution, active development and mass production attempts in each field are currently continuing, overcoming the disadvantage that manufacturing cost increases due to the production of TFT.

In particular, the strength of OLED is its picture quality competitiveness, which is 30% higher in color reproduction rate and 20 times better in contrast ratio than LCD. In addition, the biggest weakness of LCD, the afterimage of video, cannot be found in OLED. This is because LCD displays a rather complex screen by passing an indirect light source called a backlight unit through liquid crystal and color filters, while OLED directly reproduces a natural color screen by organic materials emitting light. Moreover, OLED has a very advantageous advantage in terms of manufacturing period and unit cost because its structure is simpler than that of LCD and there are fewer parts.

Due to the advantages described above, OLEDs have recently been employed as display elements in various fields, and a representative field among them is a small display field such as a smartphone. In particular, the smartphone sector has a very bright business prospect as new products are released every year and user demand for replacement is active.

However, in order to secure the performance and lifespan of OLED devices, a technology capable of blocking moisture is required. To this end, FSA (Face Seal Adhesive) and FSM (Face Seal Metal), which can realize moisture absorbent, element stiffness and heat dissipation at the same time, are used in point-and-adhesive technology, followed by press and etching processes, followed by bonding. The bonded panel has a problem in that quality defects increase due to an increase in design tolerance due to a process margin in the process of bonding FSA and FSM.

In addition, when the FSA and the FSM are respectively cut or etched and bonded, the number of processes increases, which causes an increase in cost.

In addition, due to the characteristics of the etching process, the edge of the processed FSM increases in taper and protrudes finely, so there is a limit to overcoming damage caused by stamping during bonding.

The present invention is to solve this problem, and more specifically, by supplying FSA and FSM in a roll-to-sheet manner so that they are laminated or bonded, respectively, so that the bonded panels can be cut at the same time. Therefore, an object of the present invention is to provide a display manufacturing apparatus capable of fundamentally preventing quality defects from occurring.

In addition, a plurality of laser cutting units are provided to cut the supplied panels with constant and precise quality, and a detachable division chuck is provided on the table so that display panels can be easily cut by size, so that the display panel can be cut into desired sizes. Another object is to provide a display manufacturing apparatus that can do this.

In the present invention, a division chuck is provided in the middle to cut the size of the display panel by set sizes on the first table and the second table, and by separating or attaching the division chuck, the cutting table of the display panel according to the set size is It provides a display manufacturing apparatus that can be implemented as much as possible.

According to the display manufacturing apparatus according to the present invention,

First, compared to the process of cutting or etching FSA and FSM, respectively, and then laminating or bonding, precise cutting is possible because FSA and FSM are supplied as one display panel in a roll-to-sheet method and cut through the laser cutting unit, has the effect of reducing the number of

Second, compared to the method of manufacturing FSA and FSM in separate processes, precise cutting is possible, so quality defects can be significantly reduced.

Third, the cutting process according to the various sizes of the display panel can be adjusted to the set cutting size of the display panel by detaching the split chuck from one structure,

Fourth, there is an effect of easily adjusting the set cutting size of the display panel through the attachment and detachment of the dividing chuck and the adjustment of the second table.
