Problems solved by technology

However, the quality and stability of polarizers prepared by these methods are poor, and it is not easy to install on other components
Further, due to the need for additional correction materials to solve its technical problems, the cost of existing polarizers is high and expensive
Furthermore, during the use of the polarizer, part of the incident light will be reflected and cannot pass through the polarizer, and the incident light cannot be fully utilized, resulting in weak intensity of the light emitted from the polarizer, and its application is limited

Embodiment Construction

[0010] refer to figure 1 , The first embodiment of the present invention provides a polarizer 10 , which includes: a transparent layer 100 , and the transparent layer 100 includes a first surface 110 and a plurality of parallel and equally spaced convex strips 120 . The shape of the cross-section of each of the plurality of ridges 120 perpendicular to its length direction is triangular. Each of the protrusions 120 includes a light reflecting surface 130 . A hypotenuse of the triangle is located in the light reflecting surface 130 . Each of the plurality of light reflection surfaces 130 forms an angle of 45 degrees with the first surface 110 . That is, the triangle is an isosceles right triangle.

[0011] The transparent layer 100 has light transmittance within the wavelength range of the wire grid polarizer 10 . Translucency means that light can be transmitted, and the wavelength range of use is 400 nm to 800 nm. Preferably, the light-transmitting layer has an average lig...

Abstract

The invention belongs to the field of polarizers and solves the technical problem that the intensity of light emitted from the polarizers is relatively weak. The present invention relates to a polarizer for polarizing incident light, which includes: a first transparent layer, which includes a first surface, and further includes a plurality of parallel and equally spaced light reflection surfaces, the plurality of Each of the light reflecting surfaces forms an angle θ with the first surface of the first transparent layer, and the range of the angle θ is greater than 0° and less than 90°. The light intensity of the transmitted light of the polarizer provided by the invention is relatively large.

Description

technical field [0001] The invention relates to an optical device, in particular to a polarizer. Background technique [0002] Polarizers are widely used in flat panel displays to improve display quality. There are many methods for preparing these polarizers in the prior art, such as mechanical stretching, chemical etching and so on. However, the quality and stability of polarizers prepared by these methods are poor, and it is not easy to install on other components. Furthermore, because additional correction materials are needed to solve the technical problems, the cost of the existing polarizers is high and expensive. Furthermore, during the use of the polarizer, part of the incident light will be reflected and cannot pass through the polarizer, and the incident light cannot be fully utilized, resulting in weak intensity of light emitted from the polarizer, and its application is limited. Contents of the invention [0003] In view of this, it is indeed necessary to pr...
