Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0040] Figure 1a It is a structural schematic diagram of a cylindrical lens grating 3D display device, Figure 1b for Figure 1a The schematic diagram of the cross-sectional structure of the display device shown, Figure 1c for Figure 1a Schematic diagram of the planar structure of the center cylindrical lens grating. Such as Figure 1a , Figure 1b with Figure 1c As shown, a cylindrical lens grating 20 is disposed in front of the display panel 10 . A part of the sub-pixels of the display panel 10 displays the image for the left eye, and another part of the sub-pixels ...

Abstract

The invention discloses a cylindrical lens grating and a display device. The cylindrical lens grating includes a light incident surface and a light exit surface, the light incident surface includes a plurality of concave curved surfaces arranged in sequence, the light exit surface includes a plurality of convex curved surfaces arranged in sequence, and the concave curved surface has a first central axis , the convex curved surface has a second central axis, and the second central axis is inclined relative to the first central axis. The display device includes a display panel and the above-mentioned cylindrical lens grating arranged on the light-emitting side of the display panel, the light-incident surface of the cylindrical lens grating faces the light-emitting side of the display panel, and the light emitted by the display panel passes through the The light emitting surface of the cylindrical lens grating is emitted. The display device reduces the image crosstalk between the left eye and the right eye, avoids the image crosstalk between different viewpoints, improves the image quality of the naked-eye 3D display device, and avoids dizziness of viewers.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a cylindrical lens grating and a display device. Background technique [0002] With the advancement of digital image processing technology and equipment manufacturing level, 3D display has become a popular trend in the display industry. The basic principle of the existing 3D display is "parallax produces stereo", through certain facilities or technologies, the viewer can see different images in both eyes, that is, the left eye only sees the left eye image, and the right eye only sees the right eye image. The human brain will fuse the two pictures seen by the two eyes to produce a 3D effect. [0003] Because the method of obtaining 3D display effect through 3D glasses requires the user to wear 3D glasses, which seriously affects the user's somatosensory effect and the user's effect is not good, so naked-eye 3D display has become a more popular choice for users. Naked-eye 3D dis...
