Description

Dispensing apparatus for bending of flexible OLED module [0001]

The present invention relates to a dispensing apparatus for bending a flexible OLED module, and more particularly, to a flexible OLED module for bending a portion of a flexible OLED module to prevent breakage or disconnection of components of a display when a bezel is minimized, And a dispensing device for bending the module.

In general, a flat panel display (FPD) refers to a video display device that is thinner and lighter than a television or a monitor using a cathode ray tube. Examples of such a flat panel display include a liquid crystal display (LCD), a plasma display (PDP), a field emission display (FED), and an organic light emitting diode (OLED) have been developed and used.

Dual organic light emitting diode (OLED) is a display made by using self-luminous phenomenon that emits light when current flows in a fluorescent organic compound. It is faster than a liquid crystal display (LCD) in which image quality reaction speed is widely used, It has the advantage of thinness.

However, at the edges except for the screen area of the flat panel display, a circuit device mounted for driving or controlling the display is attached, and a bezel is formed to cover the circuit device.

Particularly, in the case of a portable terminal, a technique for reducing the size of the bezel by reducing the size of the circuit device or changing the position of the bezel is being developed because the size of the bezel is reduced and the screen area is enlarged to increase portability.

Recently, flexible organic light emitting diodes (OLEDs) have been developed as encapsulated plastic film and TFT film on top and bottom of organic layer instead of glass, which is advantageous for light weight and bending.

Since the flexible organic light emitting diode is formed as a film and can be folded or twisted, the circuit device is connected to the TFT film, and then the TFT film is bent at 180 degrees to position the circuit device under the lower region to minimize the bezel area do.

However, there is a problem that the organic layer of the organic light emitting diode and the encap film are separated from the TFT film or the circuit device is separated from the TFT film by the stress generated when the flexible organic light emitting diode is bent.

However, the conventional technique as described above has a problem in that when the liquid crystal display is manufactured, since the gap is maintained and the paste is vertically applied to prevent the liquid crystal from leaking to the outside, it is still vulnerable to the stress generated during bending.

As described above, according to the dispensing apparatus for bending the flexible OLED module according to the present invention, when the circuit device of the flexible OLED module is bent to the bottom of the screen area to minimize the bezel area, each component is dispensed, When the dispensing solution is injected into the flexible OLED module, the flexible OLED module can be tilted according to the position of each component to widen the contact area between the dispensing solution and the component. When the flexible OLED module is mounted, The fencing position is automatically detected and dispensed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken as a limitation of the scope of the present invention. Or modify it. The scope of the invention should, therefore, be construed in light of the claims set forth to cover many of such variations.
