Embodiment 1

[0033] An embodiment of the present invention provides an organic light emitting device, which is a white light OLED device, and has a mixed light emitting layer 100 for emitting white light.

[0034] like figure 1 As shown, the mixed light emitting layer 100 includes a first blue light layer 10 , a second blue light layer 20 , a yellow-green light layer 30 and an exciton recombination region 50 .

[0035] The second blue light layer 20 is disposed on the first blue light layer 10 , and the yellow-green light layer 30 is disposed side by side with the second blue light layer 20 on the first blue light layer 10 . The first blue light layer 10, the second blue light layer 20, and the yellow-green light layer 30 emit light at the same time according to the modulation ratio, and the first blue light layer 10 and the second blue light layer 20 are used to emit a blue light source, The yellow-green light layer 30 is used to emit a yellow-green light source, and a corresponding pro...

Embodiment 2

[0042] An embodiment of the present invention provides an organic light emitting device, which is a white light OLED device, and has a mixed light emitting layer 100 for generating a light source.

[0043] like figure 2 As shown, the mixed light emitting layer 100 includes a first blue light layer 10 , a second blue light layer 20 , a yellow-green light layer 30 , a red light layer 40 and an exciton recombination region 50 .

[0044] The second blue light layer 20 is disposed on the first blue light layer 10, the yellow-green light layer 30 and the second blue light layer 20 are disposed side by side on the first blue light layer 10, and the red light layer 40 is located on Between the yellow-green light layer 30 and the first blue light layer 10 . The first blue light layer 10, the second blue light layer 20, the yellow-green light layer 30 and the red light layer 40 emit light simultaneously according to the modulation ratio, and the first blue light layer 10 and the secon...

Abstract

The invention provides an organic light-emitting device, a display panel and a display device. The organic light-emitting device comprises a mixed light-emitting layer, the mixed light-emitting layercomprises a first blue light layer, a second blue light layer and a yellow-green light layer, and the second blue light layer and the yellow-green light layer are arranged on the first blue light layer in parallel.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to an organic light-emitting device, a display panel, and a display device. Background technique [0002] The active matrix flat panel display has many advantages such as thin body, power saving, and no radiation, and has been widely used. Among them, Organic Light-emitting Diode (OLED) display technology is a promising flat-panel display technology, which has very excellent display performance, especially self-illumination, simple structure, ultra-thin, fast response , wide viewing angle, low power consumption, and flexible display, it is known as a "dream display". In addition, its investment in production equipment is much smaller than that of thin-film transistor-type liquid crystal displays. It has been favored by major display manufacturers and has become a The main force of the third-generation display devices in the field of display technology. At present, OLED is on the e...
