Problems solved by technology

[0003] At present, OLEDs generally have the problem of low light extraction efficiency. This is because the anode or cathode in OLEDs is generally made of transparent conductive oxides with a refractive index close to 2, such as indium tin oxide (ITO, IndiumTinOxides) with a refractive index of 1.92. There is a large refractive index difference between the ITO film and the glass substrate. When the incident light passes through the ITO film and then hits the glass substrate, part of the incident light will undergo total reflection. In this way, the light emitted from the glass substrate has Loss, resulting in low light extraction efficiency of OLED

Abstract

The invention discloses an array substrate, display panel and display device. The array substrate includes a lining substrate, a plurality of organic electroluminescent structures located on the lining substrate and a plurality of antireflection structures in one-to-one correspondence with each organic electroluminescent structure, each antireflection structure is located at one side the corresponding organic electroluminescent structure which is close to a light emergence side of the array substrate, each antireflection structure includes at least two layers of antireflection films, the antireflection films can enable light emitted by the corresponding organic electroluminescent structures to be weakened in light intensity after interference of two beams of reflected light which are reflected on two surfaces of the antireflection films, thus, transmission light interference reinforcement is realized through reflected light interference weakening when light emitted by each organic electroluminescent structure passes the corresponding antireflection structure, i.e., the intensity of transmission light is correspondingly increased through reduction of light energy lost due to reflection, and thus the luminous efficiency of an organic electroluminescent display panel can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] Among the existing flat panel display panels, organic electroluminescent display panels (Organic Electroluminescent Display, OLED) have gradually become the mainstream in the display field due to their characteristics of low power consumption, high color saturation, and wide viewing angle. OLED is a self-luminous display panel. Its light-emitting principle is that under the action of an external electric field, electrons are injected into the light-emitting layer from the cathode, and holes are injected into the light-emitting layer from the anode. The electrons and holes migrate, recombine, and decay in the light-emitting layer to emit light. [0003] At present, OLEDs generally have the problem of low light extraction efficiency. This is because the anode or cathode in OLEDs is gene...
