preparation example Construction

[0066] It can be known from the above steps of the preparation method that the method of the present invention adopts the method of laminating the retardation film and the polarizing film to form a 3D polarizing film. Only one die-cutting is carried out, and the complex operations brought about by the traditional patchwork lamination are avoided through sheet lamination, which greatly improves the production and lamination efficiency;

[0067] At the same time, since there is no need to splice different polarizing films, at least half of the splicing error can be reduced.

[0068] Further, the present invention provides a method for preparing a low-reflectivity polarized LED, which method includes the steps and step seven of the method for preparing a low-reflectivity 3D polarizing film,

[0069] Step 7. Dispensing glue on the patterned AG anti-glare glass, polarizer or LED module of the 3D polarizing film, and aligning and bonding the 3D polarizing film and the LED module to ...

Abstract

A low-reflectivity 3D polarizing film, a low-reflectivity polarizing LED, and a preparation method thereof. The present invention solves the problems of large accumulative seam errors and large crosstalk intervals in traditional polarizing film manufacturing methods, and poor flatness and high reflectivity of the manufactured products. The preparation method of the low-reflectivity 3D polarizing film of the present invention comprises: making patterned AG anti-glare glass; 1 / 2 wavelength retardation compensation film attached to the non-AG surface of the AG anti-glare glass layer; cutting to form a patterned structure ; Peel off the invalid area; fill to form a planarization layer; align the polarizer with the planarization layer or the black light-shielding layer of AG anti-glare glass to prepare a 3D polarizing film with low reflectivity. Further, glue is applied to the patterned AG anti-glare glass of the 3D polarizing film, the polarizer or the LED module, and the 3D polarizing film is aligned with the LED module to prepare a polarized LED with low reflectivity.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to the preparation technology of a 3D polarizing film and a polarizing LED. Background technique [0002] Polarized stereoscopic display is a 3D display method that uses the principle of "vibration direction" of light to realize the decomposition of the original image and stereoscopic imaging. It mainly uses left-handed and right-handed polarizing films on adjacent rows of the display device. In this way, two images with different polarization directions are sent to the viewer. When the images pass through the polarized glasses, since each lens of the polarized glasses can only accept images with one polarization direction, the left and right eyes of the person can receive two sets of images. The screen is then synthesized into a three-dimensional image by the brain. [0003] At present, the polarizing film installed on the traditional polarizing LED three-...
