Abstract

The invention discloses a collimation membrane, a collimation backlight module, a display module and a display device, and relates to the technical field of the collimation membrane. The collimation membrane is designed for solving the problem that that the collimation membrane in the prior art can cause the brightness loss. The collimation membrane comprises a collimation membrane body and multiple transmitting lattice points; multiple transmitting lattice points are dispersed at one side surface of the collimation membrane body; the transmitting lattice points have a first surface, and in the first section of the transmitting lattice points, the included angle between the tangent line of each point on the first surface and the bottom surface of the transmitting lattice points is an acuteangle, and the first section is the section parallel to a height direction of the transmitting lattice points and intersected with the first surface. The collimation membrane disclosed by the invention can be used for collimating the 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 ...
