Abstract

The invention relates to the technical field of thin-film display, and particularly relates to an anti-blue-ray optical thin-film applied to a displayer, a television display screen, a lamp box, an LED screen and a lamp, and an application thereof. In order to filer high-energy shortwave blue rays which are from the displayer and lighting equipment and damage eyes, the invention provides the anti-blue-ray optical thin-film and the application thereof. The optical thin-film comprises a functional layer, a base material layer and a protective coating layer. The base material layer is arranged between the functional layer and the protective coating layer. Anti-blue-ray additives are added in the functional layer and / or the protective coating layer. The anti-blue-ray additives are organic dyestuffs. The anti-blue-ray optical thin-film is applied to the displayer, the television display screen, the lamp box, the LED screen or the lamp so that a great anti-blue-ray effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of thin film display, in particular to an anti-blue optical film applied to displays, TV display screens, light boxes, LED screens and lamps and its application. Background technique [0002] With the popularization of electronic and digital products, people cannot do without mobile phones, computers, LCD TVs and other equipment every day. The screens of these devices will emit a large amount of high-energy short-wave blue light. These blue lights continue to irradiate our eyes and cause eye dysfunction. These extremely high-energy blue light can penetrate the lens directly to the retina, causing photochemical damage to the retina, directly or indirectly causing damage to cells in the macular area. [0003] In traditional digital products such as smartphones, monitors, and tablet computers, as well as lighting systems such as light boxes, flashlights, and lamps, the emitted light is not filtered. The emitted...
