Antireflection film, backlight module, display module and electronic equipment

Abstract

The invention provides an antireflection film. The antireflection film is composed of multiple layers of sub antireflection films including the first-part sub antireflection film, the second-part sub antireflection film and the third-part sub antireflection film; the first-part sub antireflection film is used for conducting antireflection on blue light with the wavelength ranging from the first wavelength lambda1 to the second wavelength lambda2, the second-part sub antireflection film is used for conducting antireflection on green light with the wavelength ranging from the third lambda3 to the fourth wavelength lambda4, and the third-part sub antireflection film is used for conducting antireflection on red light with the wavelength ranging from the fifth wavelength lambda5 to the sixth wavelength lambda6, wherein lambda1 is smaller than lambda2, lambda3 is smaller than lambda4, lambdaf5 is smaller than lambda6, lambda2 is smaller than or equal to lambda3 and / or lambda4 is smaller than or equal to lambda5, lambda4 is not equal to lambda5 when lambda2 is equal to lambda3, and lambda2 is not equal to lambda3 when lambda4 is equal to lambda5. According to the technical scheme, the sub antireflection films are arranged only for parts of red light wave bands, green light wave bands and blue light wave bands and not arranged on the wave bands where the blue light and the green light are overlapped and / or parts of the wave bands where the green light and the red light are overlapped, and therefore the thickness of the antireflection film can be effectively decreased.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to an anti-reflection film, a backlight module, a display module and an electronic device. Background technique [0002] With the increasing demand of users, the requirements for electronic equipment are also getting higher and higher. In addition to performance requirements, there are also requirements for product appearance. For example, there is an increasingly thinner requirement for the thickness of electronic equipment. Although manufacturers reduce the thickness of electronic equipment in various ways and from various aspects, there are still some components in electronic equipment that can still be further thinned. Contents of the invention [0003] The disclosure provides an anti-reflection film, a backlight module, a display module and electronic equipment to solve the deficiencies in the related technologies. [0004] According to the first aspect of the embo...
