Problems solved by technology

[0005] In order to reduce the impact of moiré interference on the visual effect of stereoscopic images, the current design method is to design the grating stripes of the parallax separation grating into a structure that is inclined relative to the column direction of the display screen pixels. Using this design method, the parallax separation grating While balancing the loss of resolution in the horizontal and vertical directions of the display, it reduces the impact of moiré interference on the subjective visual effect. crosstalk between sub-images of disparity, which causes ghosting of the viewed stereoscopic image and reduces the stereoscopic effect
Therefore, the use of existing inclined gratings can only slightly improve the impact of moiré interference on visual effects, but cannot fundamentally eliminate moiré, and the existing technology reduces the impact of moiré interference on vision while reducing the three-dimensional Image viewing effect

Embodiment 1

[0027] figure 2 A schematic structural view of the autostereoscopic display provided by the first embodiment of the present invention is shown, image 3 The light path diagram of the light passing through the light guide unit provided by the first embodiment of the present invention is shown, and for the convenience of description, only the parts related to this embodiment are shown.

[0028] In order to completely eliminate the moiré interference of the front grating autostereoscopic display, it is necessary to eliminate the periodic light-shielding stripes existing in the pixel array of the display screen. A pixel array 1, and a light guide array 2 arranged at the light output end of the pixel array 1. Wherein, the pixel 11 mainly includes a light-emitting area 111 and light-shielding stripes 112, and the light-emitting area 111 mainly includes a color filter film of a liquid crystal modulation layer. The light guide array 2 includes a plurality of closely connected light...

Embodiment 2

[0035] In the embodiment of the present invention, on the premise of ensuring the seamless connection between the light-emitting surfaces 211 of each light guide unit, the side walls 213 of adjacent light guide units may also be seamlessly connected, so that the entrance of each light guide unit The light surface 212 can completely cover the pixel light-emitting area 111 and the light-shielding stripes 112 .

[0036] further combined with figure 2 , in the embodiment of the present invention, on the premise of ensuring the seamless connection between the light-emitting surfaces 211 of each light-guiding unit, there may be a wedge-shaped gap between the side walls 213 of adjacent light-guiding units, so that the entrance of adjacent light-guiding units A gap of a certain width is left between the light surfaces 213, and the width of the gap may be greater than or equal to the width of the corresponding light-shielding stripe 112. At this time, the light incident surface 212 of...

Embodiment 3

[0039] In the embodiment of the present invention, the light guide array 2 may be a hollow structure whose side is coated with an optical reflective film or polished to form a reflective surface.

Abstract

The invention is suitable for the field of 3D (three-dimensional) display, and provides a free three-dimensional display free from Moire pattern interference. The free three-dimensional display comprises a pixel array consisting of a plurality of pixels, wherein each pixel comprises a light emitting region and horizontal and vertical light shielding strips positioned around the light emitting region. The free three-dimensional display is characterized in that: the light emitting end of the pixel array is provided with a light guide array consisting of a plurality of light guide units; the light emitting surfaces of adjacent light guide units are in seamless connection; and the light emitting surfaces of the light guide units completely cover corresponding pixels. The light emitting end of the pixel array is provided with the light guide array, and the light emitting surface of each light guide unit completely covers corresponding pixels, so that the light guide surface of each light guide unit becomes a new pixel light emitting surface free from light shielding strips, Moire pattern interference in a front grating type free three-dimensional display is effectively eliminated, and the viewing effect of three-dimensional display images is improved.

Description

technical field [0001] The invention belongs to the field of stereoscopic display, in particular to a free stereoscopic display without moiré interference. Background technique [0002] Glasses-free stereoscopic display technology is the ultimate development direction of 3D display technology, and grating autostereoscopic display technology is a relatively mature and feasible technical means to realize naked-eye stereoscopic display. The basic composition of the grating free stereoscopic display is a flat display and a parallax separation grating, and most of the flat displays now use liquid crystal displays or plasma displays. The parallax separation grating is divided into slit grating and lenticular lens grating. The placement position of the parallax separation grating is divided into front grating type and rear grating type. side. [0003] For flat-panel displays, whether it is a liquid crystal display or a plasma display, the primary color pixels are arranged at equa...
