Problems solved by technology

[0003] But at present, most of the existing giant liquid crystal display films are of one-piece structure, which needs to be repaired or even replaced as a whole after damage, which leads to high cost. Secondly, when splicing multiple liquid crystal display films, the inside of the film The connection between the conductive layers is not tight enough, which easily affects the use of the film

Embodiment approach 1

[0029] The present invention provides such as Figure 1-2A low-cost giant liquid crystal display film is shown, including the first light guide film 1, which has the characteristics of ultra-thin, uniform light emission, and multi-color changes. The point light source of LED can be converted into a surface light source through the color light guide film , with high refractive index and light transmittance, the upper surface of the first light guide film 1 is sequentially provided with a first horizontal polarizer 2, a first conductive layer lower film 3, a first cholesteric liquid crystal layer 4, a first conductive The film 5 on the layer, the first vertical polarizer 6 and the first insulating film 7, the first horizontal polarizer 2 and the first vertical polarizer 6 are polarizers, which are made according to the polarization principle of light, and have the function of effectively eliminating glare. Special function, the imaging of liquid crystal display must rely on pola...

Embodiment approach 2

[0035] The present invention provides such as Figure 3-5 A low-cost giant liquid crystal display film shown includes a second light guide film 9 and a third light guide film 91, and the upper surface of the second light guide film 9 is provided with a second horizontal polarizer 10 and a second conductive layer in sequence. The lower film 11, the second cholesteric liquid crystal layer 12, the upper film 13 of the second conductive layer, the second vertical polarizer 14 and the second insulating film 15, the second light guide film 9, the second horizontal polarizer 10, the second The sides of the lower film 11 of the conductive layer, the second cholesteric liquid crystal layer 12, the upper film 13 of the second conductive layer, the second vertical polarizer 14 and the second insulating film 15 are all connected by OCA optical glue. , the second light guide film 9, the second horizontal polarizer 10, the lower film 11 of the second conductive layer, the second cholesteric...

Abstract

The invention discloses a low-cost giant liquid crystal display film which comprises a first light guide film, and a first horizontal polaroid, a first conducting layer lower film, a first cholesteric liquid crystal layer, a first conducting layer upper film, a first vertical polaroid and a first insulating film are sequentially arranged on the upper surface of the first light guide film. The side faces, close to each other, of the first light guide film, the first horizontal polaroid, the first conducting layer lower film, the first cholesteric liquid crystal layer, the first conducting layer upper film, the first vertical polaroid and the first insulating film are connected in an adhesive mode through OCA optical cement. The invention also discloses a preparation process of the low-cost giant liquid crystal display film, the preparation process comprises two splicing modes, each splicing mode comprises two steps, and by setting two implementation modes, films with the same internal structure and films with different internal structures can be spliced respectively, so that the maintenance and replacement cost is reduced. According to the invention, the electrical connection between the films can be ensured to be tighter, and an open circuit is not easy to occur.

Description

technical field [0001] The invention relates to the technical field of liquid crystal films, in particular to a low-cost giant liquid crystal display film and a preparation process thereof. Background technique [0002] Liquid crystal film was first used to protect mobile phone screens, and then developed to protect LCD screens such as notebook screens. It is a protective film that can be used to protect mobile phone screens, LCD screens and other display devices. According to the principle of film adsorption, it can be divided into: Adhesive film, electrostatic film and so on. LCD protective film is not limited to protecting LCD screens. With the entry of fashion IT brand protective films into the market, more fashionable and practical factors have been added, such as frosted film, mirror film, anti-peeping film, AR film protective film, etc. . [0003] But at present, most of the existing giant liquid crystal display films are of one-piece structure, which needs to be re...
