Description
BACKGROUND OF THE
Due to the popularization of smartphones and tablet PCs, the demand for touch-enabled display panels is surging. In general, a touchable display, that is, a touch panel is manufactured by bonding a touch assembly, which is a panel to which a touch function is added, to a general display panel such as an LCD.
As shown in FIG. 1, the bonding of the display panel and the touch assembly is conventionally clear adhesive (OCA) along an edge portion of which a bezel is placed on the upper surface of the display panel DP. The tape TA is attached and the touch assembly TA is attached thereto. However, when the panel DP and the touch assembly TA are bonded together using the OCA tape TA as described above, the thickness of the OCA tape TA is thick and the overall thickness of the display device is, of course, the OCA tape. An air gap is formed on the center side without (TA), resulting in poor image quality, such as reduced sharpness and narrower viewing angle.
Recently, as shown in FIG. 2, various types of OCR (Optically Clear Resin) adhesives (AD), including Loctite® LOCA (Loctite Liquid Optically Clear Adhesives), are evenly applied to the entire upper surface of the panel (DP). By bonding the touch assembly TA thereon, the overall thickness of the display device is prevented from being thickened and image quality is prevented from being deteriorated.
However, although conventionally, a variety of bonding devices are introduced through Korean Patent No. 10-0994718, Korean Patent No. 10-1048696, and Korean Patent No. 10-1057038, etc., OCR adhesives such as Loctite® LOCA ( In the application and bonding of AD), an apparatus for automatically carrying out the entire process including supplying the panel DP and the touch assembly TA and curing the adhesive AD has not been provided in one apparatus.
In addition, even when applying a liquid adhesive material (AD), such as OCR adhesive material (AD) to the panel (DP) after bonding the touch assembly (TA) thereon, there is a problem that an air gap in the form of air bubbles on the bonding surface Of course, there is a problem in that the coating thickness of the adhesive material (AD) is not uniform because it is different from each other, the adhesive material (AD) flows outward during the bonding, the side surface of the bonding panel is contaminated and the adhesive strength is lowered.

For reference, the bonding process of the display panel and the touch assembly described above with reference to FIG. 21 is schematically shown. Referring to Figure 21 summarizes the entire bonding process sequence as follows. First, the operator manually supplies the panel to load the panel in the panel loading unit (A) (S1). The panel loaded on the panel loading unit A is coated with adhesive on the surface using a slot die and a stencil mask in the adhesive coating unit B (S2), and the used stencil mask is cleaned in the mask cleaner (S3). Then, the panel coated with the adhesive is picked up by the panel transfer part D and transferred (S4) to the lower side of the UV curing part C, where an edge curing process is performed (S5). The panel is then moved to the lower side of the second bonding chamber by the first bonding chamber of the vacuum bonding portion E. FIG. The operator manually loads the touch assembly into the second bonding chamber (S6), and after the vision alignment (S7) of the touch assembly placed in the first bonding chamber and the second bonding chamber, the first bonding chamber and the second bonding The panel is docked with the panel and the touch assembly is bonded under vacuum (S8). After the bonding is completed, the bonding panel is transferred to the UV panel transfer part D again by the first bonding chamber, where the temporary curing process S9 is performed. After the temporary curing process is completed, the panel is picked up by the panel transfer part D and then unloaded by the unloading conveyor G (S10).
