Embodiment Construction
[0066] In the following detailed description, only certain exemplary embodiments of the present invention are shown and described, simply by way of illustration. The drawings and specification are to be regarded as illustrative in nature rather than restrictive, and like reference numerals refer to like elements throughout the specification.
[0067] In this specification and the appended claims, when it is described that an element is "coupled" or "connected" to another element, the element may be "directly coupled" to the other element or "electrically coupled" through a third element to that other element. Additionally, unless expressly stated to the contrary, the word "comprise" and variations thereof should be understood to imply the inclusion of the listed elements, but not the exclusion of any other elements.

Abstract
An organic light emitting diode display includes: a display unit (130) including: a plurality of scan lines (S1, ..., Sn); a plurality of light emission control lines (GC1, ..., GCn); a plurality of data lines (D1, ..., Dm); and a plurality of pixels (140), each of the pixels (140) being coupled to a corresponding scan line (S1, ..., Sn) among the scan lines (S1, ..., Sn), a corresponding light emission control line (GC1, ..., GCn) among the light emission control lines (GC1, ..., GCn), and a corresponding data line (D1, ..., Dm) among the data lines (D1, ..., Dm); a scan driver (110) configured to transmit a plurality of scan signals (Scan(n-1), Scan(n)) to the scan lines (S1, ..., Sn); a light emission driver (160) configured to transmit a plurality of light emission control signals (GC(t)) to the light emission control lines (GC1, ..., GCn); a data driver (120) configured to transmit a plurality of data signals (Data(t)) to the data lines (D1, ..., Dm); and a power source driver (170) configured to apply a plurality of power source voltages having different levels to the pixels (140) during one frame period.
Description
technical field [0001] Embodiments of the present invention relate to an organic light emitting diode (OLED) display and a driving method thereof. Background technique [0002] Various types of flat panel display devices capable of alleviating disadvantages of a cathode ray tube (CRT), such as heavy weight and large size, have been developed in recent years. Such flat panel display devices include liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), and organic light emitting diode (OLED) displays. [0003] Among the above flat panel displays, OLED displays use organic light emitting diodes (OLEDs) that generate light through recombination of electrons and holes to display images, OLED displays have a fast response speed, are driven with low power consumption, and have excellent luminous efficiency , brightness and viewing angle, and thus has become the focus of attention. [0004] Generally, an organic light emitting diode (OLED) d...
