Abstract

The present invention discloses an organic light -emitting display panel, its color temperature regulation method and display device, including: substrate substrate, multiple emitting units set on the substrate substrate;The first electrode, the first light layer, the second electrode, the second light layer, and the third electrode set on the substrate substrate;, The second electrode and the third electrode are connected to different voltage signals respectively.According to the color temperature requirements of the organic luminous display panel, by adjusting the potential of the first electrode, the second electrode, and the third electrode, the voltage at both ends of the first light layer and the second light layer can be controlled to control the first luminous layer respectivelyThe transmission strength of the second light layer realizes the color temperature changes of the organic light display panel.

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...
