The organic light emitting display may include a plurality of pixels for generating light components with predetermined brightness components while controlling the amount of current that flows from a first power source to a second power source via organic light emitting diodes (OLED), a first power source controller for extracting data of the highest gray level among input data items of one frame and for outputting a control value having voltage information corresponding to the highest gray level data, and a first power source generator for generating a controlled voltage value corresponding to the control value and outputting the controlled voltage value to the first power source.

Organic light emitting display and method of driving the same

An organic light emitting diode (OLED) display and a method of compensating for degradation are disclosed. One inventive aspect includes a panel assembly including a plurality of pixels. Luminance measuring units are formed along a perimeter of the panel assembly to measure luminance of light emitted from the pixels. A processing unit compares the measured luminance data so as to detect and also compensate for a degraded pixel.

Organic light emitting diode display and method for compensating for degradation of pixel luminance

An organic light emitting display includes a display unit including pixels coupled to scan lines, first control lines, second control lines, and data lines, a control line driver configured to supply a first control signal and a second control signal to the pixels through the first control lines and the second control lines, a first power source driver for applying a first power to the pixels of the display unit, and a second power source driver for applying a second power to the pixels of the display unit. At least one of the first power or the second power is applied to the pixels of the display unit as voltage values having different levels during one frame. The first and second control signals and the first and second powers are concurrently provided to all of the pixels of the display unit.

Organic light emitting display including power source drivers configured to supply a plurality of voltage levels

An organic light-emitting display device that increases long range uniformity (LRU). The organic light-emitting display device includes an image display unit including a plurality of pixels defined by a plurality of scan lines and a plurality of data lines, a plurality of film type connection devices electrically connected to the image display unit and at least one DC-DC converter arranged on the plurality of film type connection devices to supply driving voltages to the image display unit.
