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 [0001] The invention relates to the field of display technology, in particular to a 3D film and a display device. Background technique [0002] With the development of the glasses-free 3D industry, more and more display devices begin to integrate glasses-free 3D displays. At present, the commonly used glasses-free 3D display methods include parallax barrier and lenticular lens. Commonly used 3D display devices usually include a display screen, a glass-free 3D film attached to the liquid crystal display, and a touch screen covered on the glass-free 3D film. For display products that do not pursue thinning, a sufficient safety distance can be left between the touch screen and the display screen with the naked-eye 3D film to avoid the occurrence of Newton's rings or optical coupling (wet-out). However, for the pursuit of thinner and integrated display products, it is necessary to close the touch screen to the naked-eye 3D film to reduce the distance, and becau...
