Embodiment Construction

[0024] The present invention provides a light guide film and a display device. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The light guide film provided by the present invention can at least be used in side-type backlight modules, such as figure 1 As shown, it includes: PET light guide layer 100 (specifically, PET with a certain thickness is used as the light guide layer, and PET reflective layer 200 is the same) and PET reflective layer 200. The PET reflective layer 200 is used for reflective side entry At least a part of the light emitted by the light source in the backlight module, and the reflected light can pass through the PET ligh...

Abstract

The invention discloses a light guide film and a display device. The light guide film is used for a lateral-entry type backlight module and comprises a PET light guide layer and a PET light reflectionlayer, wherein the PET light reflection layer is used for reflecting at least a part of light emitted by a light source in the lateral-entry type backlight module, and the reflected light can be emitted through the PET light guide layer. A light guide plate and a reflector plate in the prior art can be at least replaced by the light guide film provided by the invention, and when the light guide film and the light guide plate are compared, the material cost is lower, and the cost of the lateral-entry backlight module is reduced.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a light guide film and a display device. Background technique [0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then high-tech materials with high reflectivity and non-absorbing light are used to engrave the bottom surface of the optical-grade acrylic sheet with laser, V-shaped cross grid engraving, UV screen printing technology prints light guide points. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit light evenly. The purpose of the reflector is to reflect ...
