Example Embodiment

[0018] In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and the word "embodiment" used in the specification of the present invention is meant to be used as an example, example or illustration, and is not intended to limit the present invention. In addition, in the accompanying drawings, elements with similar or identical structures and functions are represented by the same element numbers.

[0019] The present invention provides a polarized light structure, which can be widely used in various types of displays. This polarized light structure has the effect of reducing the transmittance of low-band blue light (low-band blue and violet visible light), for example, the wavelength ran...

Abstract

The invention provides a display panel. The display panel is provided with a first polarized layer, a second polarized layer and a half-wave plate arranged between the first polarized layer and the second polarized layer, the half-wave plate can deflect the polarization direction of visible light of which the wave length is larger than a specific wave length by 90 degrees, the deflection angle of the polarization direction of the visible light of which the wave length is smaller than the specific wave length is smaller than 90 degrees, and the specific wave length is the blue or purple visible light wave length. For example, the half-wave plate can effectively change the polarization direction of the light with the wave band ranging from 430 nm to 780 nm and inefficiently change the polarization direction of the light with a low wave band ranging from 380 nm to 430 nm, the second polarized layer can effectively block permeation of the light with the low wave band ranging from 380 nm to 430 nm, and a harmful blue light wave band is successfully blocked. The display panel has the advantages of being low in blue light, healthy and capable of protecting eyes.

Description

technical field [0001] The invention relates to a display technology, in particular to a display panel and a polarizer. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for displays. In addition to the picture quality and performance of the display, people are also paying more and more attention to the harm of display products to human eyes. As far as the blue light emitted by the display screen is concerned, its energy is second only to ultraviolet rays. It can easily penetrate the eyeball and reach the retina, causing damage to the macula, which dominates vision and color recognition. Therefore, consumers' demand for display products with eye protection function is also increasing. [0003] At present, the existing display products with eye protection function are improved from their backlight sources, using long-wavelength blue light as the light source, which has low energy and dim brightnes...
