Embodiment Construction

[0020] The specific implementation manner of the present invention will be further described below in conjunction with the drawings and embodiments. The following examples are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0021] Such as figure 1 As shown, the embodiment of the present invention provides a light guiding structure, which specifically includes: a first dielectric layer 1 and a second dielectric layer 2 with different dielectric constants;

[0022] Metal nanoparticles 3 that enhance the light guiding function are provided between the interface of the first dielectric layer 1 and the second dielectric layer 2 . The dielectric constant of the first dielectric layer is set to be greater than the dielectric constant of the second dielectric layer.

[0023] When the metal nanoparticles 3 are placed in a homogeneous environment, the forward and back scattering of light by the metal nanoparticles 3 are almost symm...

Abstract

The invention relates to the field of display technology, in particular to a light guide structure, an OLED (Organic Light-Emitting Diode) display component and a display device. The light guide structure comprises a first medium layer and a second medium layer which have different dielectric constants; metal nanoparticles for enhancing the light guide effect are arranged between the interfaces of the first medium layer and the second medium layer. The light guide structure, the OLED display component and the display device which are provided by the invention have the advantage that because the metal nanoparticles are arranged between the two light guide layers, the luminous exitance can be increased to the max.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide structure, an OLED display device and a display device. Background technique [0002] OLED is a device that uses a multi-layer organic thin film structure to generate electroluminescence. It is simple to manufacture and only requires a low driving voltage. These main features of OLED are very prominent in the application of flat-panel displays. OLED display technology is very likely to become the next generation of mainstream flat-panel displays. However, like liquid crystal displays, the development of OLED displays also has many limiting factors, such as low light emission efficiency. After the light emitted by the OLED passes through various insulating layers and color filters, only part of the light can pass through the panel and be observed by the human eye. In order to enhance the competitiveness of OLED display technology and liquid crystal display technol...
