Problems solved by technology
In addition, in some specific technical fields, such as in the field of LED, the shape of existing LED chips is mostly cuboid or cylinder, and the light emitted by such light-emitting diodes is non-polarized light. When it is used in LCD displays When used as a backlight source, it is necessary to set polarizers on both sides of the liquid crystal to control the light output. This method will increase the thickness of the display, and the light beam will be controlled by the polarizer twice, which will greatly reduce its energy efficiency.

The invention relates to the field of preparation of elliptical nanorods, in particular to an elliptical nanorod, a preparation method of a light-emitting diode and a display device. The preparation method of the elliptical nanorod comprises the following steps: providing a first substrate; forming a layer to be patterned on the surface of the first substrate, wherein the layer to be patterned is of a single-layer structure or a multi-layer structure; arranging at least one nano structure on the surface of the layer to be patterned, wherein at least one section of the nano structure is elliptical; and etching the layer to be patterned by taking the nanostructure as a first mask to obtain the elliptical nanorod. According to the preparation method of the elliptical nanorod provided by the invention, the elliptical nanorod can be prepared only by preparing the to-be-patterned layer under the existing process, arranging the nanostructure on the surface of the to-be-patterned layer and using the nanostructure as the mask, and the preparation method of the elliptical nanorod has the advantages that the steps are simple, the implementation is easy, and the preparation method can be widely applied to production practice.
Description
technical field [0001] The invention relates to the field of preparation of elliptical nanorods, in particular to a preparation method of elliptical nanorods, a light emitting diode and a display device. Background technique [0002] In the existing technology, the preparation of cylindrical nanorods is relatively common, but there are few related technologies for the preparation of elliptical nanorods. Therefore, how to realize the rapid and efficient preparation of elliptical nanorods is an urgent problem to be solved. In addition, in some specific technical fields, such as in the field of LED, the shape of existing LED chips is mostly cuboid or cylinder, and the light emitted by such light-emitting diodes is non-polarized light. When it is used in LCD displays When it is used as a backlight source, it is necessary to set polarizers on both sides of the liquid crystal to control the light output. This method will increase the thickness of the display, and the light beam w...
