Description

Technical Field

[0001] The present invention relates to the field of naked-eye 3D display technology, and in particular to a low-resolution vertical and horizontal naked-eye 3D display method. Background Art

[0002] Smart wearable products have five basic characteristics: mobility, wearability, sustainability, simple operability, and interactivity. With the continuous development and innovative integration of mobile communications, imaging technology, artificial intelligence and other technologies, driven by global applications and experiential consumption, wearable devices have developed rapidly and have become one of the fastest growing high-tech markets in the world.

[0003] With the development of science and technology, people have higher and higher requirements for display imaging effects. People's ultimate expectation is to simulate reality and realize 3D display. Naked-eye 3D display technology does not require viewers to wear auxiliary equipment to watch 3D images, which will not cause inconvenience to viewers and will not cause harm to human eyes. Therefore, naked-eye 3D display technology has become a research hotspot in the field of display technology in the world.

[0004] As the wearable market matures, wearable product consumers are increasingly demanding low-resolution naked-eye 3D display technology, so low-resolution naked-eye 3D imaging effects have become the next outlet for wearable products. Currently, naked-eye 3D technology is mainly used in large horizontal screen display devices, such as TVs, outdoor displays, etc. Low-resolution naked-eye 3D display technology has not been effectively promoted and applied.

[0005] like Figure 2 and Figure 3 As shown, in the existing 3D display panel production process, it is necessary to calculate the distance (h) between the fence and the pixel based on the through-hole spacing (L) and the designed viewing distance (S), the screen PPI (to achieve the ability to observe a pixel through a single fence gap with one eye, P) and the length of the fence (C), and then produce the 3D display panel. However, the naked-eye 3D display screen has strict restrictions on the viewing position. Only by standing in the right position can the left and right eyes see the corresponding perspective of the picture content, and produce the spatial stereoscopic visual experience that can be felt when standing in the shooting position. Summary of the invention

[0006] To solve the above problems, the present invention discloses a low-resolution vertical screen horizontal naked-eye 3D display method, including a main control unit, an image processing unit, a display unit, an eye tracking unit, a liquid crystal control unit and a liquid crystal barrier unit.

[0007] The image processing unit processes the image into images received by the left and right eyes, and then plays it on the display unit through the main control unit. That is, the left and right eyes see images with different parallaxes, and the images will form depth information after being processed by the brain, realizing the naked eye 3D effect.

[0008] The eye tracking unit obtains the viewing angle and position of the left and right eyes, and sends the obtained data to the main control unit, and then generates a control instruction in combination with the information of the picture playback, and the control instruction is transmitted to the liquid crystal control unit to control the liquid crystal barrier unit. The liquid crystal barrier unit is provided with liquid crystal vertical bars, which are energized and opaque to achieve the effect of blocking the line of sight, that is, the left and right eyes can obtain different pictures.

[0009] The liquid crystal barrier unit is provided with multiple layers of liquid crystal vertical bars, and each layer of liquid crystal vertical bars is provided with multiple bars. In the conventional liquid crystal barrier unit, only one layer of liquid crystal vertical bars is provided. When the naked eye observes, the position of the eyeball changes, and the naked eye 3D effect is lost. Here, several layers of liquid crystal vertical bars are provided, so that the liquid crystal barrier unit has a 3D structure. When the eyeball position changes, the brightness of each layer of liquid crystal vertical bars can be controlled, thereby increasing the movable position of the eyeball. Preferably, the liquid crystal barrier unit comprises two front and rear substrates, a plurality of film layers and spacers are arranged between the two substrates, the film layers are provided with openings, and the vertical liquid crystal strips are located in the openings.

[0010] Preferably, the surfaces of the film layer and the spacer are printed with conductive circuits, and are electrically connected to the vertical liquid crystal bars, so as to realize the conductivity of the vertical liquid crystal bars, thereby controlling whether to block light.

[0011] Preferably, each of the vertical liquid crystal strips is independently controlled.

[0012] Preferably, the equidistant positions of the liquid crystal vertical stripes in each layer are grouped together. For example, if 1 to 10 stripes are provided in each layer, 1, 3, 5, 7, 9 and 2, 4, 6, 8, 10 can be respectively grouped together, or 1, 4, 7, 10 can be grouped together, 2, 5, 8 can be grouped together, and 3, 6, 9 can be grouped together for control.

[0013] Preferably, each layer of the vertical liquid crystal strips is independently controlled.

[0014] The beneficial effects of the present invention are as follows: By changing the structure of the liquid crystal barrier unit, that is, setting multiple layers of liquid crystal vertical strips, the liquid crystal barrier unit can have a 3D shading effect. When the position of the eyeball changes, each layer of liquid crystal vertical strips can be controlled to perform shading, thereby increasing the visible range and improving the naked eye 3D viewing effect.

DETAILED DESCRIPTION

[0017] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figures 1 to 5 As shown, a low-resolution vertical screen horizontal naked eye 3D display method includes a main control unit 2, an image processing unit 1, a display unit 6, an eye tracking unit 4, a liquid crystal control unit 3 and a liquid crystal barrier unit 5. The main control unit 2 is used to process calculation data, the image processing unit 1 is used to process the played image, the display unit 6 is used to play the image, the eye tracking unit 4 obtains the real-time position of the eyeball, and the liquid crystal control unit 3 controls the liquid crystal barrier unit 5 to block the light, so that the left and right eyes can obtain different pictures.

[0019] The image processing unit 1 processes the image into images received by the left and right eyes, and then plays it on the display unit 6 through the main control unit 2. The images viewed by the left and right eyes are arranged on the display unit 6 in an alternate manner. For example, if the horizontal pixel coordinates of the left eye's image are 12345, and the horizontal pixel coordinates of the right eye's image are abcdf, then the arrangement on the display unit 6 is 1a2b3c4d5f, or 12ab34cd.

[0020] The eye tracking unit 4 obtains the viewing angles and positions of the left and right eyes, and sends the obtained data to the main control unit 2, and then generates a control instruction in combination with the information of the picture playback, and the control instruction is transmitted to the liquid crystal control unit 3 to control the liquid crystal barrier unit 5. Under the obstruction of the liquid crystal barrier unit 5, the left eye can only obtain pixel coordinates 12345 from the display unit 6, and the right eye can only obtain pixel coordinates abcdf from the display unit 6.

[0021] The liquid crystal barrier unit 5 is provided with multiple layers of liquid crystal vertical bars 54, and each layer of liquid crystal vertical bars 54 is provided with multiple bars. The liquid crystal barrier unit 5 has a 3D structure, and the change of the front and rear position of the eyeball can maintain the effect of naked eye 3D by controlling each layer of liquid crystal vertical bars 54, that is, the visual range of naked eye 3D is increased, and the viewing effect is improved.

[0022] The liquid crystal barrier unit 5 comprises two front and rear substrates 51 , and a plurality of film layers 52 and spacers 53 are arranged between the two substrates 51 . The film layers 52 are provided with openings, and the liquid crystal vertical stripes 54 are located in the openings.

[0023] Conductive circuits are printed on the surfaces of the film layer 52 and the spacer layer 53, and are electrically connected to the liquid crystal vertical stripes 54. The liquid crystal vertical stripes 54 are energized to block light.

[0024] Under the control of the liquid crystal control unit 3, the liquid crystal barrier unit 5 has the following operation modes: 1. Each liquid crystal vertical strip 54 is independently controlled; 2. Each layer of liquid crystal vertical strips 54 is located at an equidistant position as a group. For example, each layer is provided with 1 to 10 strips, and 1, 3, 5, 7, 9 and 2, 4, 6, 8, 10 can be controlled as a group, or 1, 4, 7, 10 can be controlled as a group, 2, 5, 8 can be controlled as a group, and 3, 6, 9 can be controlled as a group; 3. Each layer of liquid crystal vertical strips 54 is independently controlled. The more the number of independent controls mentioned above, the greater the control requirements for the liquid crystal control unit 3.

[0025] When the human eye is at the eyeball observation position 8, the vertical liquid crystal strip 54 completely blocks the viewing angle range 7. Figure 2 As shown, when the liquid crystal vertical strip 54 is not fully opened, the viewing angle range 7 can be Figure 3 As shown. Note that Figure 2 and Figure 3 Only a portion of the viewing angle range 7 of the eyeball is shown.

[0026] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
