  • Display device and method of controlling a gate driving circuit having two shift modes
    Patent number: 9251735
    Abstract: A display device and a method of controlling a gate driving circuit thereof are discussed. The display device includes a display panel, first and second gate driving circuits which are respectively disposed on both sides of the display panel, and a timing controller. The timing controller controls the first and second gate driving circuits in conformity with a first shift mode, compares carry signals received from the first and second gate driving circuits, and controls the first and second gate driving circuits in conformity with a second shift mode when a time interval between the carry signals is greater than a previously determined reference value.

  • Optical compensation method and driving method for organic light emitting display device
    Patent number: 9087482
    Abstract: An optical compensation method for an organic light emitting display device comprises: setting initial gain values of RGB subpixels; making each of the RGB subpixels converge on target luminance; selecting subpixels to emit light with the W subpixel from the RGB subpixels, and setting an initial gain value of the W subpixel; measuring color coordinates and luminance of the W subpixel to which the initial gain value is applied; calculating the luminance ratio of the W subpixel and the selected subpixels; adjusting maximum gains of the W subpixel and the selected subpixels; measuring maximum color coordinates and luminance ratio of the W subpixel and the selected subpixels; and making the W subpixel and the selected subpixels converge on target color coordinates and luminance.
