Abstract
The invention provides a 3D film and a display device. The 3D film comprises a transparent substrate layer and a micro structure layer. The micro structure layer comprises basic column lenses arranged on the transparent substrate layer and structural column lenses arranged among the basic column lenses, wherein the basic column lenses and the structural column lenses extend in the same direction, and the rise of the structural column lenses is larger than the rise of the basic column lenses. According to the 3D film, an enough safe distance is reserved between the 3D micro structure and a touch screen or between the 3D micro structure and a display screen, so that when the 3D film is compounded to the display device, a Newton ring or optical coupling phenomenon is prevented. Meanwhile, the 3D film can still keep the original 3D display function, and adverse influences on the display device are avoided. When the 3D film is compounded to the display device, a Newton ring prevention layer does not need to be additionally arranged between the 3D film and the touch screen, and a thinner display device is obtained conveniently.
Description
Technical field
The present invention relates to display technique field, in particular to a kind of 3D film and display device.
Background technology
Along with the development of bore hole 3D industry, increasing display device starts to integrate bore hole 3D display.At present, conventional bore hole 3D display mode has disparity barrier and lens pillar two kinds of modes.Conventional 3D display device generally includes display screen, fits in the bore hole 3D film in LCDs, and is covered in the touch-screen on bore hole 3D film.For not pursuing for lightening display product, the generation that enough safe distances come to avoid Newton ring or optically-coupled (wet-out) phenomenon can be reserved between touch-screen and the display screen posting bore hole 3D film.But, for pursuing lightening, integrated display product, need touch-screen to be close to bore hole 3D film with decreased distance, and because the column mirror grating line number of bore hole 3D film is higher and post mirror rise is smaller, Newton ring or wet-out phenomenon will be produced.
For simple non-bore hole 3D display device, usually adopt optical cement bonding with or Newton ring-preventing film two kinds of modes, reduce the gap between touch-screen and display screen and ensure not produce Newton ring.According to optical cement bonding, adhesion technique is relatively loaded down with trivial details, and easily produces bubble for large-sized display screen, thus causes harmful effect to display device.According to Newton ring-preventing film, generally mix fine-grained bonding agent by sandblasting or employing due to existing Newton ring-preventing film and form Newton ring preventing layer, when reality watches this display device, in Newton ring-preventing film, particulate can produce scattering process to light, thus beholder can be made to produce twinkling phenomenon; Simple is on the other hand increase for solving Newton ring the waste that thin film also result in space.
For the bore hole 3D display device adopting post mirror structure, reduce the gap of touch-screen and display screen if want, touch-screen need be close to post 3D film display screen on.Column mirror grating line number due to 3D film is higher and post mirror rise is smaller, will produce Newton ring or wet-out phenomenon after being affixed on by touch-screen on 3D film.If add one deck Newton ring preventing layer between 3D film and touch-screen again, then can increase the gap of touch-screen and display screen, and still may produce wet-out phenomenon between 3D film and Newton ring-preventing film.
