Problems solved by technology

Therefore, compared with the case of two-dimensional display, the resolution is reduced by at least half
In addition, the parallax barrier stereoscopic display has a large energy loss, resulting in a darker picture; while the cylindrical lens stereoscopic display cannot achieve high-resolution 2D / 3D bidirectional conversion

Embodiment 1

[0026] Structure of a stereoscopic display

[0027] figure 1 An overall structural diagram of the naked-eye stereoscopic display without resolution reduction of the embodiment is shown. figure 2 A block diagram of a circuit responsible for display control in the naked-eye stereoscopic display is shown. Such as figure 1 As shown, the naked-eye three-dimensional display includes: an image display unit 3 (which can be a liquid crystal display (LCD) panel, an organic light-emitting display (OLED) panel, a transparent organic light-emitting display (TOLED) panel, preferably a liquid crystal display panel), arranged on the image The optical element 2 on the back of the display unit 3 (can be a lens, a Fresnel lens, a linear Fresnel lens and their array, a cylindrical lens array, and the above-mentioned devices and arrays composed of liquid crystal or other materials with similar functions ), and the backlight module 1 arranged behind the optical element 2 . The backlight modu...

Embodiment 2

[0050] Next, the present invention will describe the naked-eye stereoscopic display of Embodiment 2. The same reference numerals are used for the same components in the autostereoscopic display according to Embodiment 1, and will not be described again.

[0051] In the above-mentioned embodiment 1, a binocular stereoscopic display is described as an example, but this embodiment 2 is applicable to the case of multi-view stereoscopic display. In the case of stereoscopic display with m viewing angles, the backlight part is subdivided into 2m small units, m small units are used as light sources for the left eye point of view, and m small units are used as light sources for the right eye point of view. Such as Figure 5B As shown, what is displayed is not only a three-dimensional display with three viewing angles, each backlight group in the backlight part is as follows Figure 5B As shown, it is subdivided into six small units, three small units are used as light sources for the...

Abstract

The invention discloses a rear naked-eye three-dimensional (3D) display and a display method. The rear naked-eye 3D display comprises an image display unit, an optical element and a backlight module, wherein the image display unit can provide a display panel of a fully-high-resolution parallax image; the optical element propagates backlight energy to different visual areas in space; and the backlight module is formed by combining a switch and small backlight units, and the brightness of each small backlight unit can be freely controlled. Light which is emitted by the backlight module passes through the optical element, penetrates through the image display unit and then is used for loading the parallax image, so different parallax images can be seen through eyes at different spatial positions, or different images can be seen at different viewpoints. Meanwhile, by controlling the specific brightness combination of the small backlight units in the backlight module, a high-resolution two-dimensional (2D) image can be played. By the invention, under the condition that 3D display is realized, adding of glasses is eliminated, the resolution of the display is prevented from being reduced, and 2D / 3D bidirectional switching without resolution reduction is realized.

Description

technical field [0001] The invention relates to a three-dimensional display, which belongs to the technical field of three-dimensional display, in particular to a three-dimensional display and a display method for obtaining naked-eye three-dimensional display through the cooperation of an optical element, a display unit and a backlight part. Background technique [0002] In the existing technology, there are stereoscopic display systems that can achieve stereoscopic vision with naked eyes without wearing auxiliary glasses, and autostereoscopic display technologies that use the parallax barrier method and the cylindrical lens method are applied in fields such as mobile phones and digital signage. [0003] The basic principle of autostereoscopic display technology: the parallax barrier (or cylindrical lens array) is set directly in front of the image display unit (such as a picture tube, flat panel display panel, etc.), and the synthesized image on the display unit needs to pas...
