Problems solved by technology

[0002] With the advent of the information age, conventional cathode ray tube (CRT) displays have been replaced by flat panel displays. One of the most used flat panel displays is liquid crystal display (LCD). LCD has the characteristics of mature technology and low price, but Since LCDs are not self-illuminating, there are technical limitations in terms of contrast, viewing angles, flexible displays, and power consumption

Abstract

The invention relates to an OLED display panel. The OLED display panel comprises a first electrode and a second electrode which are oppositely arranged and a laminate arranged between the first electrode and the second electrode, wherein the laminate at least comprises a first auxiliary light emitting layer and a light emitting layer which are sequentially arranged from the first electrode; the first auxiliary light emitting layer selects a host-guest doped form, a radialene compound is doped in a host material, hole injection rate is improved by utilizing stronger hole injection capacity of the radialene compound, voltage of a device is reduced, further light emitting efficiency is improved, and a horizontal leakage current phenomenon is reduced.

Description

technical field [0001] The invention belongs to the field of organic electroluminescence, and in particular relates to an OLED display panel, a manufacturing method and electronic equipment containing the same. Background technique [0002] With the advent of the information age, conventional cathode ray tube (CRT) displays have been replaced by flat panel displays. One of the most used flat panel displays is liquid crystal display (LCD). LCD has the characteristics of mature technology and low price, but Since LCDs are not self-illuminating, there are technical limitations in terms of contrast, viewing angles, flexible displays, and power consumption. Organic light-emitting diodes (OLEDs) have the characteristics of self-illumination, wide viewing angle, short response time, high luminous efficiency, wide color gamut, low operating voltage, thin panels, and the ability to produce large-sized and flexible displays, so they have attracted much attention. [0003] An existing...
