Display module and preparation method

A display module, comprising:

• a display component and an anti-dazzle component,
• wherein the anti-dazzle component comprises:
• an anti-dazzle module, a selective reflecting sheet and a first phase-difference film;
• the selective reflecting sheet is overlaid on a first surface of the display component, and the first phase-difference film is arranged between the anti-dazzle module and the selective reflecting sheet, wherein a first light-filtering sheet is overlaid on the first surface of the display component, the first light-filtering sheet is configured to convert a light emitted by the display component into a linearly-polarized light, the anti-dazzle module is configured to pass through a first polarized light or a second polarized light, a polarization vector of the first polarized light is located in a plane formed by an incident light and a corresponding reflected light thereof, and a polarization vector of the second polarized light is perpendicular to a plane formed by an incident light and a corresponding reflected light thereof;
• and
• a polarization direction of a light reflected by the selective reflecting sheet is the same as that of a light passing through the first phase-difference film, and a polarization direction of a light reflected by the selective reflecting sheet is opposite to that of a light passing through the selective reflecting sheet.
