Abstract

The invention provides an organic light-emitting display device. The organic light-emitting device comprises a positive electrode layer, a negative electrode layer and an organic light-emitting dielectric layer, wherein the organic light-emitting dielectric layer is arranged between the positive electrode layer and the negative electrode layer and comprises a hole injection layer, a hole transmission layer, a first hybrid layer, a light-emitting layer, an electron transmission layer and an electron injection layer which are sequentially arranged, the first hybrid layer comprises a bipolar main body material and is doped with at least one of a material with an electron blocking function and a material with a hole control function, and the bipolar main body material has a function of simultaneously transmitting holes and electrons. By the organic light-emitting device, injection barriers of carriers of the holes and the electrons in the organic light-emitting device can be reduced, the injection rate of the carriers and the position of a carrier combination region are controlled, the carrier combination efficiency is improved, so that the organic light-emitting device with high efficiency and long lifetime is obtained.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting display device. Background technique [0002] Organic light-emitting display (Organic Light-emitting Display, OLED) technology is well known in the art, and has the characteristic of self-luminescence. Unlike liquid crystal display (Liquid Crystal Display, LCD) technology, OLED does not require an additional backlight source. In addition, OLED also has the advantages of thin thickness, light weight, low driving voltage and energy consumption, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, flexible display and large-area full-screen display. With many advantages such as color display, it is recognized by the industry as the display device with the most development potential. [0003] Organic light-emitting display devices are divided into two types: active...
