Abstract

Provided are an organic light emitting display device, the display device including: a substrate defined into a display area and a non-display area; sub-pixels formed on the display area of the substrate; and dummy sub-pixels formed on the non-display area of the substrate, the dummy sub-pixels have a different shape for each position of the non-display area.

Claims (13)

1. An organic light emitting display device, comprising:

a substrate defined into a display area and a non-display area;

sub-pixels formed on the display area of the substrate; and

dummy sub-pixels formed on the non-display area of the substrate,

wherein the dummy sub-pixels corresponding to different positions of the non-display area comprise one or more first dummy sub-pixels including both an organic light emitting diode (OLED) part and a thin film transistor (TFT) part of the sub-pixels, one or more second dummy sub-pixels including the OLED part of the sub-pixels without the TFT part of the sub-pixels, and one or more third dummy sub-pixels including the TFT part of the sub-pixels without the OLED part of the sub-pixels.

2. The organic light emitting display device of claim 1 , wherein the first, the second, and the third dummy sub-pixels are disposed so that the second and third dummy sub-pixels are alternated with each other.

3. The organic light emitting display device of claim 1 , wherein a number of the dummy sub-pixels is different for each position of the non-display area.

4. The organic light emitting display device of claim 1 , wherein upper dummy sub-pixels formed on an upper portion of the non-display area have a same arrangement structure as lower dummy sub-pixels formed on a lower portion of the non-display area, and right dummy sub-pixels formed on a right side of the non-display area have a same arrangement structure as left dummy sub-pixels formed on a left side of the non-display area.

5. The organic light emitting display device of claim 1 , wherein upper dummy sub-pixels formed on an upper portion of the display area have a different arrangement structure from lower dummy sub-pixels formed on a lower portion of the display area, and right dummy sub-pixels formed on a right side of the display area have a different arrangement structure from left dummy sub-pixels formed on a left side of the display area.

6. The organic light emitting display device of claim 1 , wherein upper dummy sub-pixels formed on an upper portion of the display area have a same arrangement structure as lower dummy sub-pixels formed on a lower portion of the display area, and right dummy sub-pixels formed on a right side of the display area have a different arrangement structure from left dummy sub-pixels formed on a left side of the display area.

7. The organic light emitting display device of claim 1 , wherein upper dummy sub-pixels formed on an upper portion of the display area have a different arrangement structure from lower dummy sub-pixels formed on a lower portion of the display area, and right dummy sub-pixels formed on a right side of the display area have a same arrangement structure as left dummy sub-pixels formed on a left side of the display area.

8. The organic light emitting display device of claim 1 , wherein the first, the second, and the third dummy sub-pixels are defined into a single dummy pixel.

9. The organic light emitting display device of claim 1 , wherein four of the dummy sub-pixels are defined into a single dummy pixel.
