Problems solved by technology

[0004] At present, the optical composite film is mainly developed to replace the structure of the traditional brightness enhancement film and diffusion film with a composite film. Compared with two films, the thickness of a single composite film is often thinner, which makes the composite film easy to crush the light guide plate. In addition, there is also the problem of low impact resistance of falling balls, which leads to white spots on the frequently clicked positions on the screen during the use of the display device, which affects the use; The molding glue on the optical composite film also has a crucial impact on a series of properties of the optical composite film. Therefore, how to obtain the molding glue suitable for the optical composite film of this application and how to improve the performance of the above optical composite film has become the main research direction of this application.

The service life is prolonged.

Description

【Technical field】 [0001] The technical field of the optical film of the present invention, in particular relates to a molding glue and its application. 【Background technique】 [0002] Liquid crystal display panels have been widely used in the display screens of computers, mobile phones, televisions, navigators, digital cameras and some instruments. Since the liquid crystal panel itself does not emit light, the backlight module, as one of the key components of the liquid crystal display panel, plays a role in providing sufficient brightness and uniform light. [0003] The basic composition of the backlight module except the light source includes from bottom to top: reflective film, light guide plate, diffusion film and brightness enhancement film, etc. With the high-definition and ultra-high-definition requirements of the liquid crystal module and the thin design requirements, various optical The design of the film puts forward new requirements, and the composite design of v...
