Abstract

The present disclosure provides a display panel, a polymer organic light-emitting device and a preparation method thereof. The polymer organic light-emitting device includes: an organic light-emitting layer with opposite first and second surfaces; an electron transport part, stacked on the first surface of the organic light-emitting layer; and a hole transport part, stacked on the organic light-emitting layer The second surface of the light-emitting layer includes a hole injection layer and a hole transport layer that are stacked in sequence; the hole transport part also includes a median energy level layer; the energy level of the median energy level layer is between and adjacent to it. between the two membrane layers. The present disclosure can improve the current efficiency of a polymer organic light-emitting device.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to an organic light emitting device, a method for preparing the organic light emitting device, and a display panel including the organic light emitting device. Background technique [0002] With the rapid development of science and technology, people's requirements for display panels are also increasing day by day, which makes the display panels develop in the direction of being lighter, thinner, and more power-saving. Therefore, organic light-emitting diode display panels are produced. Compared with traditional liquid crystal display panels, organic light-emitting diode display panels are self-illuminating displays that do not require a backlight module that consumes a lot of energy, so they can be lighter, thinner, and more power-saving, so they have received more and more attention. . [0003] According to different organic light-emitting materials used, organic li...
