Abstract

A manufacturing method of an organic light emitting diode (OLED) display includes: supplying a circuit film on the pad area of the display panel and bonding a first end portion of the circuit film to the pad area; vertically standing and inserting the display panel in a bonding device; holding a portion of the circuit film including a second end portion to be horizontal by using a rotating device including a vacuum absorbing portion; supplying a flexible printed circuit (FPC) into a space under the second end portion of the circuit film, and attaching the flexible printed circuit to the second end portion of the circuit film; and operating the rotating device to move the second end portion to a vertical position, and separating the circuit film from the vacuum absorbing portion.

Claims (7)

1. An organic light emitting diode (OLED) display device, comprising:

a display panel including a substrate having a display area and a pad area, and an encapsulation member covering the display area;

a flexible printed circuit (FPC) disposed on the encapsulation member, the flexible printed circuit not directly connected to the pad area; and

a circuit film including a first end portion formed with a first bonding surface that is attached to the pad area and a second end portion formed with a second bonding surface that is attached to the flexible printed circuit, the circuit film maintaining a flatness from the first end portion to the second end portion, the first bonding surface and the second bonding surface positioned facing the substrate.

2. The organic light emitting diode display device of claim 1 , further comprising a gate driver, gate wires, a data driver, data wires, and a plurality of pixels, the display panel including the plurality of pixels being positioned on the display area, the display panel including the gate wires and the data wires being positioned on both the display area and the pad area.

3. The organic light emitting diode display device of claim 2 , wherein at least one of the gate driver and the data driver is installed to the circuit film to drive the display panel, and the circuit film is made of a chip on film or a tape carrier package.

4. The organic light emitting diode display device of claim 2 , wherein the gate driver and the data driver are positioned on the pad area as a chip on glass, and the circuit film is made of a flexible printed circuit film.
