    Abstract: The present invention provides an OLED display device including a display panel, a data driver and a timing controller. The display panel has sub-pixels for displaying images. The data driver supplies a data signal to data lines of the sub-pixels. The timing controller supplies the data signal to the data driver and controls the data driver. The data driver outputs a stress prevention voltage for preventing application of stress to driving transistors included in the sub-pixels in response to a stress compensation signal output from the timing controller, and the stress prevention voltage is applied to M (M being an integer equal to or greater than 1) sub-pixels selected per frame.

    Abstract: According to embodiments of the present disclosure, there may be provided a controller, a display device and a driving method. In consideration of that a hysteresis by an image data voltage supplied to a subpixel during an active time may exert an influence on a real-time sensing process, by correcting a reference sensing driving data voltage on the basis of an offset voltage, it is possible to correct the influence of a hysteresis exerted on sensing of the characteristic value of a driving transistor.

    Abstract: A four-primary-color organic light emitting display comprises: a display panel where a plurality of first-color pixels, second-color pixels, third-color pixels, and fourth-color pixels are disposed; and a data drive circuit that has a single, digital-to-analog converter to generate first- to fourth-color data voltages and to apply the first-color data voltage to the first-color pixels, the second-color data voltage to the second-color pixels, the third-color data voltage to the third-color pixels, and the fourth-color data voltage to the fourth-color pixels. Herein, the maximum grayscale voltages for the first- to fourth-color data voltages are adjusted to be different on a single gamma graph defined as the input grayscale versus output voltage.

    Abstract: The present disclosure relates to a pixel sensing device and the organic light emitting display device including the same which reduce or minimize the influence of the panel noise and improve sensing accuracy and sensing reliability. The pixel sensing device includes a current integrator connected to a pixel through a sensing line of a display panel and integrating a pixel current flowing through the pixel to generate an integrator output voltage; a sample and hold unit sampling and holding the integrator output voltage; an analog to digital converter (ADC) converting the integrator output voltage output from the sample and hold unit into a digital signal; and a first capacitor serving to reduce or minimize a distortion degree of the integrator output voltage due to panel noise mixed to the pixel current.
