Abstract
An organic light-emitting diode display panel is disclosed. By using four display panels sequentially disposed in a stack arrangement from top to bottom, light emitted in a same direction from each of the display panels, and subpixels of the four display panels not overlapping one another, a screen resolution of the organic light-emitting diode display panel can increase by three times without increasing pixel density of masks or density of array layers.
