The present invention relates to an aging apparatus for an active organic light emitting diode module integrated with a mounting table, a control unit, and a power supply unit, and more particularly, has a compact structure to reduce the volume so that the aging treatment of the AM OLED module can be simultaneously processed in large quantities. In addition, the present invention relates to a control unit of an active organic light emitting diode module which minimizes signal attenuation between lines and an integrated aging device of a rack.

Organic Light Emitting Diodes (OLEDs) use organic materials as light emitting layers and are called organic light emitting diodes because their electrical characteristics are similar to those of diodes. It is a display using a principle of forming a layer of an organic material layer between the anode and the cathode, applying a voltage to the anode and the cathode layer, and injecting electrons and holes from the cathode and the anode to recombine the organic material layer to generate light. Currently, OLEDs are mainly used for small display devices, and their range is very diverse, such as mobile phones, car stereos, display windows of digital cameras, portable game consoles, and displays of watches or shavers.

OLEDs can be divided into passive matrix and active matrix depending on the driving method. The passive type has a simple structure in which an organic layer is inserted between the anode wiring and the cathode wiring. In the active type, TFT (Thin Film Transistor) is attached to each pixel so that power consumption is low and image quality such as resolution is excellent. .

These active organic light emitting diodes (AM OLEDs) use fluorescent materials in the manufacturing process, so they cannot be guaranteed by simple functional tests (short time drive). Therefore, they must be tested for performance and function after aging for a certain period of time. Product reliability can be guaranteed. Accordingly, the AM OLED module aging equipment is an equipment for performing electrical aging by repeatedly outputting display patterns to a plurality of modules for quality control of a product module having a driving IC attached to an AM OLED manufactured in a production line.

And since most of them have their own power cables, the line connection for power supply and signal transmission to the AM OLED module 1 mounted in the chamber 10 is essential. In this case, the lines such as power supply and signal transmission of each device are long, and the noise is mixed in the power supply level, which causes a problem in that the aging test of the AM OLED module 1 occurs. In addition, since the lengths of the cables are different from each other, they are cluttered on the rear of the chamber 10 and the control main body 20, so that they do not look aesthetically and there are problems such as cable damage due to external exposure.

Therefore, the present invention for solving this problem is to simplify the structure of the AM OLED module is formed by integrally forming the product stack and the control unit and the power supply unit of the aging device of the AM OLED module to overcome the area of the narrow production plant The purpose is to provide an aging device.
