Abstract

The invention provides a display system and a display device. The display system includes a display screen and a lens array, the lens array is arranged on the display side of the display screen, and is used to convert the two-dimensional image displayed on the display screen into a three-dimensional image, and also includes a light modulation structure, the light modulation structure is fixedly arranged on the display screen and Between the lens arrays, there are at least two types of modulations for the lengths of the optical paths that are used to make the display light emitted by the display screen incident on the lens arrays. Compared with the existing technology of increasing the depth of field of stereoscopic display by dynamically adjusting the position of the sub-lens in the lens array, the display system will not reduce the resolution of the three-dimensional image, and can avoid the noise caused by the position change of the sub-lens from affecting the image display; Compared with the existing technology of setting the sub-lenses in the lens array with different focal lengths and apertures to increase the depth of field of the stereoscopic display, it is not necessary to design differently for the sub-lenses in the lens array, which reduces the difficulty and difficulty of processing the entire display system. cost.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a display system and a display device. Background technique

[0002] At present, in an integrated imaging display system, a lens array is usually arranged on the display side of the display screen for displaying two-dimensional images to realize three-dimensional image display on the display screen. That is, the lens array can make the image displayed on the display screen present a three-dimensional effect.

[0003] The object distance and lens focal length of the integrated imaging display system determine the image distance of the displayed image. The image distance of the displayed image of the display system refers to the distance between the three-dimensional image and the optical center of the lens. The image distance represents the central depth plane of the three-dimensional stereoscopic imaging. Location. The central depth planes of three-dimensional stereosc...
