[0002] Holographic technology is a true three-dimensional display technology that uses the principle of interference recording, diffraction and reproduction, but it has not been widely used due to its technical complexity.

It suspends the image of an object in mid-air to create a strong sense of depth. The four planes of the tetrahedron project images of the object at four angles, and the object is deliberately rotated. This display method is a 2D display, but it can produce a 3D sense at certain angles, which is in line with the omnidirectional characteristics of holography.

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] A holographic screen structure, referring to Figure 1 , including a holographic screen body 10, in which a rolling component and a transmission bar 20 rollingly arranged on the rolling component are arranged, the rolling component rolls along the length direction of the holographic screen body 10, and the rolling component can drive the transmission bar 20 to roll along the length direction of the holographic screen body 10 from top to bottom, so that the image that should be displayed by the holographic screen body 10 corresponding to the row of pixels is displayed for each row passing through the holographic screen body 10, and then with the help of the human eye POV visual retention, a complete display image is formed, that is, the mobile phone display interface, so as to achieve the naked eye 3D display effect.

[0024] Further, refer to Figure 1 The transmission bar 20 is a holographic pixel bar. There are multiple transmission bars 20. The multiple transmission bars 20 are distributed along the length direction of the holographic screen body 10. The multiple transmission bars 20 roll from top to bottom along the length direction of the holographic screen body 10 to make the display effect of the holographic screen body 10 more delicate, and play the effect of constantly refreshing the display screen to achieve the naked-eye 3D effect.

[0025] Reference Figure 1 The rolling assembly includes two rolling wheels 30 and a rolling belt 40 sleeved between the two rolling wheels 30. The two rolling wheels 30 are respectively located near the upper and lower edges of the holographic screen body 10, and the distance between the two rolling wheels 30 is the length of the holographic screen body 10. There are two rolling belts 40, both of which are sleeved between the two rolling wheels 30, and the two rolling belts 40 are respectively sleeved at the two ends of the rolling wheels 30, and the two rolling belts 40 are arranged opposite to each other. The distance between the two rolling belts 40 is the length of the rolling wheels 30, that is, the width of the holographic screen body 10.

[0026] Reference Figure 1The transmission bar 20 is transmitted between the two rolling belts 40. The length of the transmission bar 20 is consistent with the length of the rolling wheel 30. The rolling of the rolling wheel 30 drives the rolling belt 40 to transmit from top to bottom along the length direction of the holographic screen body 10, so as to drive the transmission bar 20 between the two rolling belts 40 to move from top to bottom along the length direction of the holographic screen body 10. Driven by the two rolling belts 40, the multiple transmission bars 20 move from top to bottom along the length direction of the holographic screen body 10. In the process from top to bottom, each time a row of pixels of the holographic screen body 10 is passed, the picture corresponding to this row of pixels is displayed. Then, with the help of the human eye POV visual persistence, a complete display image is formed. When the user watches the displayed picture, a naked-eye 3D display effect is formed.

[0027] Further, refer to Figure 2 The rolling assembly is connected with a driving assembly 50 for driving the rolling wheel 30 to roll. There are two driving assemblies 50, which are respectively located at two outer sides of the rolling wheel 30. The two driving assemblies 50 are used to drive the two rolling wheels 30 respectively, so as to realize the transmission of the two rolling wheels 30 with the driving belt 40 and the driving transmission bar 20. The outer sides of the two driving assemblies 50 are both covered with a shell 60, and the shell 60 covers the rolling belt 40. The shell 60 is set in a rectangular shape to adapt to the shape of the holographic screen body 10.

[0028] Reference Figure 2 The holographic screen body 10 is provided with a protective shell 70 relative to the periphery of the rolling assembly. The protective shell 70 is located at the upper and lower sides of the holographic screen body 10 to protect the rolling wheels 30 located at the upper and lower sides of the holographic screen body 10. The protective shell 70 covers the periphery of the two rolling wheels 30. The two ends of the protective shell 70 are respectively connected to the two outer shells 60, thereby forming the outer shell 60 of the holographic screen body 10.

[0029] Reference Figure 1 The holographic screen structure has a rolling component and a plurality of holographic pixel strips. The plurality of holographic pixel strips roll from top to bottom along the length direction of the holographic screen body 10 as the rolling component rolls. Each holographic pixel strip displays the picture corresponding to a row of pixels when it passes through a row of pixels of the holographic screen body 10. With the help of human eye POV visual persistence, a complete display image is formed. When the user watches the displayed picture, a naked-eye 3D display effect is formed, which improves the user's viewing experience.
