Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.

Drum for roll-to-roll deposition, roll-to-roll deposition apparatus and film roll

A roll to roll fabrication apparatus includes: a vacuum chamber having an installation chamber and a process chamber; a preprocessing unit in the installation chamber to process a surface of a film which is transferred to enhance a film characteristic in a subsequent CVD process; a process drum in the process chamber to wind the film thereon; a process treatment unit in the process chamber to form a layer by performing a CVD process on the film wound on the process drum; and a plurality of heaters in the installation chamber and the process chamber to gradually increase a temperature of the film wound on the process drum to prevent application of a thermal impact to the film due to the high-temperature process drum.

Roll to roll fabrication apparatus for preventing thermal impact

A roll to roll fabrication apparatus includes an injection plate for injecting a chemical treatment liquid on a film transferred from a supplying roll to a collecting roll; and liquid blocking rolls disposed between the supplying roll and the collecting roll, and configured to prevent the chemical treatment liquid injected from the injection plate from being introduced to another process region.

Roll to roll fabrication apparatus

A method for manufacturing an organic light emitting display device includes forming a substrate insulating film an upper surface, a lower surface, and at least one of two side surfaces of a substrate and forming an organic light emitting diode (OLED) on the substrate on which the substrate insulating film is formed. An organic light emitting display device includes a substrate having a first surface, a second surface opposite to the first surface, and side surfaces that extend between the first surface and the second surface, a substrate insulating film disposed on the first surface, the second surface, and at least one of the side surfaces of the substrate, and an OLED disposed on one of the first surface or the second surface of the substrate including the substrate insulating film.

Organic light emitting display device and manufacturing method thereof

An OLED display device having a touch sensor is provided. The touch sensor includes a base layer; a plurality of first touch electrodes arranged in a first direction on a first surface of the base layer; a plurality of second touch electrodes arranged in a second direction crossing the first direction on a second surface of the base layer; a plurality of first routing wires connected to the first touch electrodes on the first surface of the base layer, respectively; a plurality of second routing wires separated from the plurality of first routing wires and formed on the first surface of the base layer; and a plurality of third routing wires connected to the second routing wires respectively via holes, and formed on the second surface of the base layer. The base layer is one of a barrier layer, an anti-scratch layer, and a circular polarization layer.

OLED display device having touch sensor and method of manufacturing the same

A touch screen panel for a display device includes layers of polymer formed on both sides of a substrate for forming driving electrodes and sensing electrodes. The substrate may be made of materials such as polyethylene terephthalate (PET). Instead of bonding a window cover made of a heavy material, layers or polymer are formed on both sides of the substrate to afford rigidity to the touch screen panel. By removing the window cover, the weight and thickness of the touch screen panel can be reduced.
