  • Publication number: 20130063330
    Abstract: An organic light-emitting display device which may widen a swing range of a green sub-pixel. In the organic light-emitting display device, from among red, green, and blue sub-pixels, an overlapping area of material layers forming a thin film transistor, a boost capacitor and/or a storage capacitor of the green sub-pixel is greater than an overlapping area of the same material layers forming a thin film transistor, a boost capacitor and/or a storage capacitor of the red and blue sub-pixels. Accordingly, since a swing range of the green sub-pixel having relatively high light-emitting efficiency is widened, more accurate gradation may be displayed, a reliable product may be realized, a brightness variation of the organic light-emitting display device may be reduced, and the risk of poor image quality may be reduced.

  • Publication number: 20130052902
    Abstract: In a method of repairing a display panel, only a defective portion of the display panel is lighted. Heat generated from the lighted defective portion is detected to obtain a position of a defect in the defective portion. A laser is irradiated onto the defective portion to repair the defective portion. The heat generated from the lighted shorted portion is detected using infrared light to obtain an accurate position of the defect in the shorted portion. Thus, an invisible minute defect such as a tiny short can be accurately repaired, so that a yield of the display panel is improved.
