Display screen structure with grating film

By setting the grating film body and capacitive screen in the display structure, and sealing and bonding with edge sealing glue, the grating film body is reversed to reduce the focal length, the problem of small field angle of view in traditional 3D display screens is solved, achieving a larger field angle and a better 3D display effect.

AI Technical Summary

Technical Problem

The traditional naked-eye 3D display screen has a large curvature and a small field of view angle due to the smooth surface of the columnar grating film being directly pasted with the LCD screen, which limits the user's viewing experience.

Method used

A display screen structure is designed with a grating film. By setting a grating film body on one side of the liquid crystal display screen and a capacitance screen on the other side of the liquid crystal display screen, sealing and bonding between the three with edge sealing glue, and bending the grating film body backward to reduce the focal length between the grating and the liquid crystal display screen, reducing the curvature of the grating film, and increasing the field of view.

Benefits of technology

By shortening the focal length between the grating and the LCD screen, reducing the curvature of the grating film, increasing the field of view angle, and improving the display effect and user experience of the naked-eye 3D display, the range of 3D effects can be displayed is larger.

Abstract

The utility model relates to the technical field of integrated imaging display, in particular to a display screen structure with a grating film, which comprises a liquid crystal display screen. A grating film body is arranged on one side of the liquid crystal display screen, and a capacitive screen is arranged on the other side of the grating film body; edge sealing glue is arranged among the capacitive screen, the liquid crystal display screen and the outer side of the grating film body. The grating film body further comprises a grating film smooth surface layer and a grating film rough surface layer, and the grating film smooth surface layer is arranged on the side, close to the capacitive screen, of the grating film body. According to the utility model, the focal length of each small grating in the liquid crystal display screen and the grating film body can be reduced through the mounting mode of reversely buckling the grating film body, so that the focal length is shortened, the actual curvature of the grating film body is reduced, the long angle of the grating film body is enlarged, namely, the field angle is enlarged, and the range capable of displaying the D effect is larger; therefore, the display effect and the use experience of the naked eye D display screen are improved.
