Abstract: An organic light emitting display and a method of compensating for a threshold voltage thereof are disclosed. The organic light emitting display includes a display panel including a plurality of pixels, a gate driving circuit generating first and second threshold voltage sensing gate pulses, a data driving circuit which supplies a threshold voltage sensing data voltage to the pixels in response to the first threshold voltage sensing gate pulse and detects a source voltage of a driving thin film transistor (TFT) of each pixel as a sensing voltage in response to the second threshold voltage sensing gate pulse, and a timing controller which modulates input digital video data for the image display based on a change in the sensing voltage and generates digital compensation data.

Abstract: A display device may include a display panel and a driver circuit. The display panel may include subpixels, data lines, and reference voltage lines. The driver circuit may drive the data lines. A first subpixel may be connected to a first data line and a first reference voltage line. A driving time of the first subpixel may include a first initialization time in which a reference voltage is applied to the first reference voltage line and a first tracking time in which a voltage of the first reference voltage line increases from the reference voltage. During the first tracking time, a first data signal transferred to the first subpixel through the first data line may be changed from a first voltage value to a reference driving voltage value. The first voltage value may be higher than the reference driving voltage value. The display device may reduce a sensing time.
