Integrated imaging three-dimensional display system

Abstract

The invention discloses an integrated imaging three-dimensional display system, and relates to the field of three-dimensional display. The system comprises an illumination unit, a lens unit and a display screen; the lens unit is arranged between the illumination unit and the display screen; the illumination unit is used for providing brightness for the element image loaded by the display screen; the lens unit comprises a Fresnel lens and a lens array; the Fresnel lens is arranged between the illumination unit and the lens array, and the Fresnel lens is used for converting light emitted by theillumination unit into parallel light; and the lens array is used for changing the transmission direction of the parallel light. According to the integrated imaging three-dimensional display system provided by the invention, the thickness of the display system can be reduced while the display brightness of the display system is improved.

Description

technical field [0001] The invention relates to the field of three-dimensional display, in particular to an integrated imaging three-dimensional display system. Background technique [0002] The existing integrated imaging 3D display system uses the backlight unit of the traditional LCD, so the overall light intensity is limited, and the brightness is very low when watching 3D images, which affects the viewing experience. At the same time, the traditional way is to place the lens array on the front of the LCD display, so the gap between the different unit lenses in the lens array will seriously interfere with the imaging effect, so it needs to be supplemented by other equipment to reduce the interference of light such as the lens array, but the auxiliary equipment usually The distance from the LCD display is far away, which not only further reduces the intensity of effective light, but also greatly increases the thickness of the device, which seriously affects the overall th...
