[0032] The features of the roller device according to the present embodiment include that the length of the region in which the vacuum suction force is applied can be varied according to the specifications of the film-like member to be attached. To this end, as shown in FIG. 2, the drum 100 according to the present embodiment includes: an adsorption drum 110; a vacuum pipe 120; a connecting member 130; a vacuum section regulator 140;

[0033] As shown in FIG. 3, the adsorption roller 110 has a large-diameter cylindrical structure whose circumference is larger than the long side of the conventional largest membrane member. The entire surface of the adsorption roller 110 is punched with a plurality of adsorption holes 112 . Specifically, a plurality of suction holes 112 are uniformly punched on the cylinder having a predetermined thickness to allow the membrane member to be attached to the outer peripheral surface of the cylinder by suction. In this case, it is preferable that ...

Abstract

The present invention discloses a roll device used for adhering a membrane part to any surface of a flat panel display equipment unit. The roll device is characterized in that, the length of an area to be applied a vacuum adsorptive power is capable of changing according to the specification of the membrane part to be adhered.

Description

technical field [0001] The present invention relates to a roller device for use in the operation of attaching a membrane member to any surface of a flat panel display device unit. Background technique [0002] Recently, as the modern society shifts toward informatization, the importance of information display devices has remarkably increased. Examples of information display devices mainly employed are liquid crystal displays (LCDs), plasma display panels (PDPs), organic light emitting devices (OLEDs), and the like. Among the above-mentioned information display devices, the importance of liquid crystal displays is gradually increasing nowadays. In particular, liquid crystal displays are attracting high attention as a substitute capable of overcoming problems with cathode ray tubes (CRTs), relying on various advantages such as small size, light weight, and low power consumption. Correspondingly, liquid crystal displays are gradually expanding in their fields of use. [0003...
