Abstract: The present invention relates to the technical field of display devices, and discloses an organic electroluminescent display device. The display device comprises a cathode, a Q+ quantum dot layer, a light emitting layer, a Q? quantum dot layer, and an anode stacked together. The display device further comprises a capacitor, two electrode plates of which are connected with the Q+ quantum dot layer and the Q? quantum dot layer respectively, wherein the Q+ quantum dot layer and the Q? quantum dot layer are used for emitting light waves having the same wavelength as those of the light emitting layer, and wherein the capacitor charges when a control device for controlling the light emission of the light emitting layer is switched on and starts to discharge when the control device is switched off.

Abstract: The present disclosure relates to a display substrate and a driving method thereof as well as a display device. The display substrate includes: a plurality of pixels, each pixel including a plurality of sub-pixels; and a plurality of voltage control units, each voltage control unit being configured to selectively provide a same voltage or different voltages to the sub-pixels of respective ones of the plurality of pixels.

Abstract: A display panel and its driving method and driving device are provided for selectively reducing display resolution of a display panel, thereby decreasing display power consumption.

Abstract: A display driving method and device and a display device are disclosed. The method includes: receiving an image signal to be displayed; converting the image signal to be displayed into a virtual pixel array formed by virtual sub-pixels of three colors, and determining the gray scale of each virtual sub-pixel; dividing three successive sub-pixels in a row direction into a pixel unit, and arranging a sampling area at a corresponding position of each pixel unit in the virtual pixel array; and determining the gray scale of the sub-pixel of each color in the pixel unit according to the gray scale of the virtual sub-pixel of each color covered by the sampling area.
