Problems solved by technology

[0004] Vehicle-mounted display panels are greatly affected by visible light in application scenarios, and the light-shielding part structure in the light control film with spaced light-transmitting parts and light-shielding parts has a high reflectance for visible light, generally 4-10. Therefore, cause poor display

Abstract

The embodiment of the invention discloses a light control film, a preparation method thereof and a display device. In one specific implementation mode, the light control film comprises a plurality of light shading parts arranged at intervals in the direction intersecting with the light incident side of the light control film and light transmitting parts arranged between the adjacent light shading parts, and diffuse reflection surfaces are formed on the end surface and / or the side wall surface, away from the light incident side of the light control film, of the light shading parts. According to the embodiment, the end surface and / or the side wall surface of the shading part are / is made into the uneven diffuse reflection surface, so that the reflectivity of the light control film to visible light is effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a light control film, a preparation method thereof, and a display device. Background technique [0002] At present, in the field of car driving, the light-emitting surface of the vehicle-mounted display panel installed in the car can usually be attached with a light control film, which can narrow the range of the light-emitting angle of the vehicle-mounted display panel, thereby avoiding driving at night. At this time, the outgoing light from the on-board display panel is reflected on the windshield, which interferes with the driver's line of sight and affects driving safety. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Vehicle-mounted display panels are greatly affected by visible light in application scenarios, and the light-shielding part structure in t...
