Embodiment Construction

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, a display system and a display device provided by the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0037] In order to solve the technical problems of low display image resolution, high implementation difficulty, high cost and impact on display image quality existing in the existing technical solutions for increasing the stereoscopic display depth of field of the display system, Embodiment 1 of the present invention provides a display system ,like image 3 and Figure 4 As shown, it includes a display screen 1 and a lens array 2. The lens array 2 is arranged on the display side of the display screen 1, and is used to convert the two-dimensional image displayed on the display screen 1 into a three-dimensional image. The display system also includes a light modulation structure 3, and the...

Abstract

The invention provides a display system and a display device. The display system comprises a display screen and a lens array, wherein the lens array is arranged on the display side of the display screen and is used for converting a two-dimensional image displayed by the display screen into a three-dimensional image; the display system further comprises a light modulation structure; and the light modulation structure is fixedly arranged between the display screen and the lens array and is used for modulating the length of an optical path, through which the display light sent by the display screen is irradiated into the lens array into two types. Compared with the existing technology of increasing the stereo display depth of field through dynamically adjusting the positions of sub-lenses inthe lens array, the display system does not reduce the resolution ratio of the three-dimensional image and is capable of avoiding the positions of the sub-lenses from generating noise to influence theimage display; and compared with the existing technology of increasing the stereo display depth of field through setting the sub-lenses in the lens array into different focal lengths and calibers, the display system does not need to carry out different designs on the sub-lenses in the lens array, thereby reducing the processing difficulty and cost of the whole display system.

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...
