Abstract: There are provided a source driver integrated circuit, a controller, an organic light emitting display panel, an organic light emitting display device, and a method for driving the organic light emitting display device. Thus, it is possible to provide a structure in which different sensing components configured to sense sub-pixel characteristics can sense characteristics of the same sub-pixel together, and the structure enables more accurate recognition of a sensing difference between the sensing components on the basis of sensing values obtained from the respective sensing components and the sensing difference to be corrected using the recognized sensing difference. Thus, an image quality can be improved.

Abstract: A display device includes a switching circuit; a sub-pixel having a driving transistor and an organic light emitting diode (OLED) with an anode connected to the driving transistor; a driving voltage supply line to supply a driving voltage to the OLED through the driving transistor; a base voltage supply line connected to a cathode of the OLED through the switching circuit; a ground line to supply a ground voltage to the switching circuit; a first capacitor between the driving voltage supply line and the ground line; and a second capacitor between the base voltage supply line and the ground line. The switching circuit selectively supplies one of a first level voltage and a second level voltage as the base voltage, and the second level voltage is higher than the first level voltage at the ground voltage.
