The invention discloses an organic light emitting display panel, a color temperature adjustment method thereof and a display device. The organic light emitting display panel comprises a substrate and multiple light emitting units arranged on the substrate, wherein each light emitting unit comprises a first electrode, a first light emitting layer, a second electrode, a second light emitting and a third electrode arranged sequentially on the substrate along a light outgoing direction of the organic light emitting display panel; the emitted light wavelength of the first light emitting layer is larger than that of the second light emitting layer; and the first electrode, the second electrode and the third electrode are connected onto different voltage signal ends respectively. According to color temperature requirements of the organic light emitting display panel, through adjusting potential of the first electrode, the second electrode and the third electrode, voltage applied to two ends of the first light emitting layer and the second light emitting layer is controlled respectively, the emitted light intensities of the first light emitting layer and the second light emitting layer are thus controlled respectively, and the color temperature changes of the organic light emitting display panel are thus realized.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel, a method for adjusting its color temperature, and a display device. Background technique [0002] With the rapid development of display technology, users have higher and higher requirements on the color display effect of display devices. Compared with liquid crystal display devices, Organic Light Emitting Diode (OLED) display devices have excellent characteristics such as self-illumination, high contrast, fast response speed, and wide viewing angle, and are increasingly valued by the industry. [0003] Currently, OLED display panels display colors in the following ways. One is the color mode that utilizes the sub-pixels of each color to emit light independently. The color mode needs to arrange the three primary colors through the evaporation of a fine metal mask. In addition to the high cost, the alignment of the pixel and the mask and t...
