  • Patent number: 10141380
    Abstract: Discussed is an organic light emitting display device including a plurality of pixels, where red sub pixels and blue sub pixels of adjacent pixels are aligned in a first direction and are also aligned in a second direction, the second direction being a direction that intersects the first direction. Also, the green pixels of adjacent pixels are aligned in the first direction and are also aligned in the second direction. And the at least one green sub pixel of each pixel is disposed between the at least one red sub pixel and the at least one blue sub pixel of the each pixel, and the at least one green sub pixel is offset from the at least one red sub pixel and the at least one blue sub pixel in the first direction and the second direction in the each pixel.

  • Publication number: 20170193911
    Abstract: Various embodiments relate to an EM signal control circuit, an EM signal control method, and an organic light emitting display device. The EM signal control circuit according to an embodiment of the present invention includes additional elements (e.g., a transistor and a capacitor) configured to separate a set signal from a gate electrode of a transistor coupled to an output node and to stably keep turn-off of a transistor coupled to the output node. Voltage levels of a first emission power source and a first gate power source may be set differently from each other according to the present invention. Therefore, despite of a threshold voltage change of a transistor coupled to an output node, the transistor may remain turned off stably, thereby improving the reliability of the EM signal.
