Abstract

The invention discloses a collimation film, a collimation backlight module, a display module and a display device, relates to the field of collimation film technology, and is invented to solve the problem that the collimation film in the prior art can cause brightness loss. The collimating film includes a collimating film body and a plurality of light-transmitting dots, a plurality of light-transmitting dots are dispersedly arranged on one side surface of the collimating film body, the light-transmitting dots have a first surface, and the first light-transmitting dots In the cross-section, the angle between the tangent of each point on the first surface and the bottom surface of the light-transmitting dots is an acute angle, and the first cross-section is a cross-section parallel to the height direction of the light-transmitting dots and intersecting the first surface. The invention can be used for collimation of backlight.

Description

technical field [0001] The invention relates to the technical field of collimating films, in particular to a collimating film, a collimating backlight module, a display module and a display device. Background technique [0002] With the rapid development of display technology, its display range and application scenarios are constantly expanding, and the application scenarios of anti-peep display have emerged as the times require. The content on the display screen is clearly displayed, and the people who display the two screens cannot see the content on the display screen, thereby providing observers with a sufficiently private viewing experience. [0003] The core of anti-peep display technology is the collimation of light, that is, the backlight provided by the backlight of the display panel can be emitted in a specific direction, so that it can enter the eyes of the user facing the display screen, and the collimation film It is a diaphragm that can make the light emitted ...
