Embodiment 1

[0024] This embodiment provides a naked-eye three-dimensional image display method, which is an improvement on the existing lenticular 3D display technology, see below figure 2 ~ Figure 5 describes the method in detail.

[0025] 201. The control device makes the two-dimensional display screen display the left-eye image at the first moment, and simultaneously applies a first set of voltages to the liquid crystal lens above the two-dimensional display screen, so that the left-eye image passes through the The liquid crystal lens projects to the viewer's left eye.

[0026] Specifically, such as image 3 As shown, the liquid crystal lens can be an electrically controlled lens, which includes a first transparent electrode 31, a second transparent electrode 32, and a liquid crystal layer 33 sandwiched between the two transparent electrodes. A substrate 34 is attached. The liquid crystal lens utilizes the characteristic that the liquid crystal molecules 35 rotate around the rotati...

Embodiment 2

[0041] This embodiment provides a naked-eye three-dimensional image display device, which improves the existing lenticular 3D display, see below Figure 6 This device will be described in detail.

[0042] The naked-eye three-dimensional image display device includes: a two-dimensional display screen 61 for displaying two-dimensional images, a control device 62, and a liquid crystal lens 63 located on the light-emitting surface of the two-dimensional display screen. Those skilled in the art can understand that the light-emitting surface refers to the side of the two-dimensional display screen on which images are displayed.

[0043] Wherein, the control device 62 is used to make the two-dimensional display screen 61 display the left-eye image at the first moment, and apply a first set of voltages to the liquid crystal lens 63 synchronously, so that the left-eye image can be transmitted through The liquid crystal lens 63 is projected to the left eye of the observer; the control ...

Abstract

The invention discloses a naked-eye three-dimensional image display method and device, relates to the technical field of three-dimensional display, and solves the problem that the resolution of a lenticular 3D display prepared by the existing lenticular 3D display technology will decrease. In the embodiment of the present invention, since all the pixels on the two-dimensional display screen are used to display the left-eye image or the right-eye image at the same time, it is not necessary to use different pixels to display the images viewed by the left and right eyes, thus avoiding Reduced resolution of lenticular 3D displays.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display, in particular to a naked-eye three-dimensional image display method and device. Background technique [0002] With the wide application of three-dimensional (3D) display technology, electronic products such as televisions, mobile phones, and game consoles have begun to add 3D display functions. 3D display technology is mainly divided into two types, naked-eye 3D display technology and glasses-type 3D display technology. [0003] The glasses-type 3D display technology has the advantage of not reducing the resolution, but it needs to wear special glasses when watching the 3D effect of the image, which is costly and inconvenient. And the naked-eye 3D display technology can intuitively see the 3D effect of the image without wearing special glasses, which can significantly increase the convenience and user experience, so it is currently receiving widespread attention. [0004] Glas...
