Embodiment Construction

[0026] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] As described in the background technology section, in order to achieve lamination between films, optical films in the prior art either insert the ridges of the brightness-enhancing film prisms into the adhesive layer, or change the shape of the prism ridges to match other optical films Bonding, in short, sacrifices the ridge of the prism, that is, sacrifices a certain brightness enhancement effect to achieve the purpose of bonding.

[0028] In the optical film provided by the present invention, by changing the design of the prism structure of the brightness enhancing film and the arrangement of the adhesive layer, it avoids sacrificing the prism ridge when laminating it with other optica...

Abstract

The invention provides an optical film. The optical film comprises a first optical film and a second optical film, wherein the first optical film comprises a substrate layer, a prism layer and an adhesive layer. The optical film is characterized in that the prism layer comprises multiple prism structures, at least one of the prism structures has a first peak ridge and a second peak ridge, the first peak ridge and the second peak ridge form a groove, the adhesive layer is filled into the groove, and the first optical film is bonded with the second optical film through the adhesive layer. According to the optical film, the double-peak structure is arranged on the prism structure to form the groove which is filled with the adhesive layer, a tip structure of the prism structure of the first optical film can be prevented from being sacrificed, and brightness of the optical film is improved.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to an optical composite film. Background technique [0002] As display technology continues to advance, liquid crystal displays (LCDs) are increasingly used in handheld computing devices ranging from personal digital assistants (PDAs) to video game consoles, as well as in larger devices such as laptop computers , LCD monitors and TV screens. The LCD panel itself does not emit light, so the backlight module as the source of brightness is an important component of the LCD display function. The brightness enhancement film is very important for improving the brightness of the LCD display. The core of the brightness enhancement film to achieve the brightness enhancement function is the prism structure. With the market's demand for thinner display devices, more and more manufacturers are trying to combine the brightness enhancement film with other functional films to reduce the thi...
