Definitions
- Embodiments of the present invention relate to a cylindrical lens grating, a liquid crystal grating, and a display device. Background technique
- 3D display has become a major trend in the display industry.
- the current 3D display is based on "parallax" to create a three-dimensional effect, that is, through a certain facility or technology, the viewer can see different images in both eyes, the left eye only sees the left eye image, and the right eye only sees the right eye.
- the image, the left eye image and the right eye image are respectively taken from two different angles for an object, and are therefore also referred to as stereoscopic image pairs.
- the viewer's brain combines the two images seen by both eyes to produce a 3D effect.
- the way to obtain a 3D display through the 3D eyepiece requires the user to wear a 3D eyepiece, but this seriously affects the user experience, limits the user's freedom, and does not work well for myopia or farsighted users. Therefore, the eye 3D display is increasingly becoming a more popular choice for users.
- the eye 3D display technology can be divided into two main technologies: parallax barrier (also known as slit grating) and cylindrical lens lenticular lens.
- the parallax barrier is a baffle plate with a series of slit gratings arranged in front of the display screen so that the user can see different images separately.
- the baffle due to the presence of the baffle, it will inevitably block a portion of the light from the display. This not only fails to make full use of the light of the display screen, but also causes energy loss, and the light transmittance is limited, which also has a certain negative impact on the display effect. Therefore, although the technique of slit grating appears earlier, its popularity is not high.
- a cylindrical lens grating is a cylindrical lens (column lens that can be either a convex lens or a concave lens) placed in front of the display screen. Some sub-pixel units on the display show the left eye image, and the other part shows the right eye image. Because of the refraction of the lens on the cylindrical lens grating, the light emitted by the left and right eye sub-pixel units passes through the cylindrical lens grating, and the light propagation direction is deflected, so that the light emitted by the left-eye pixel is incident on the viewer's left eye, right eye. The light emitted by the pixel enters the viewer's right eye.
