Abstract
Description
Technical Field
[0001] This application relates to the field of glasses-free 3D display technology, specifically to a glasses-free 3D display device with grating distortion correction. Background Technology
[0002] Glasses-free 3D display technology refers to a technology that allows viewers to see stereoscopic images without wearing special glasses. This technology uses a combination of lenticular glass and a display screen to convert two-dimensional images into three-dimensional images, enabling viewers to experience depth and realism. Glasses-free 3D display technology is widely used in entertainment, education, medical, and industrial fields, and has broad application prospects.
[0003] Existing glasses-free 3D modules typically use a method of bonding glass and grating together. The fabricated grating glass is then attached to the display screen using double-sided adhesive, ensuring that the distance between the grating and the display screen is exactly equal to the focal length of the grating. However, during use, the double-sided adhesive bonding method cannot adjust the distance between the grating and the display screen. When the focal length changes, it cannot be adjusted, affecting the 3D visual effect. Summary of the Invention

[0031] The adjustment mechanism includes a threaded rod 11 and a slider 12. The threaded rod 11 is rotatably connected inside the sliding groove 8, and the slider 12 is slidably connected inside the sliding groove 8. The slider 12 is threadedly connected to the threaded rod 11, and the grating glass 6 is disposed on the slider 12. Rotating the threaded rod 11 causes the slider 12 to slide back and forth inside the sliding groove 8 along the opening direction of the sliding groove 8, thereby adjusting the positional distance between the grating glass 6 and the display screen 13, which is used to correct the grating distortion of the display unit.
[0032] In some embodiments, one end of the threaded rod 11 passes through one side of the mounting base 1 and is provided with a rotating mechanism for driving the threaded rod 11 to rotate.
[0033] In some embodiments, the rotation locking mechanism includes a rotation knob 9 and a fixed sleeve 10. The fixed sleeve 10 is fixedly installed on one side of the mounting base 1. A bearing 14 is provided inside the fixed sleeve 10. The threaded rod 11 is sleeved inside the bearing 14. A limit block 16 is provided at the end of the threaded rod 11.
[0034] In some embodiments, the rotating knob 9 is movably sleeved on the fixed sleeve 10, the rotating knob 9 is provided with a locking block 15, the limiting block 16 is provided with a locking groove 17, the locking block 15 and the locking groove 17 are correspondingly provided, and the locking block 15 and the locking groove 17 are adapted to each other.

[0036] In some embodiments, a telescopic mechanism is provided between the fixed frame 2 and the adjusting frame 3 for telescopic adjustment according to the adjustment distance between the fixed frame 2 and the adjusting frame 3.
[0037] In some embodiments, the telescopic mechanism includes a first sealing cover 4 and a second sealing cover 5, which are slidably disposed on the mounting base 1. A groove 41 is provided on one side of the first sealing cover 4, and the second sealing cover 5 is slidably connected inside the groove 41.

The rotation of the threaded rod 11 causes the slider 12 to slide back and forth inside the sliding groove 8 along the opening direction of the sliding groove 8.

The display screen 13 is turned on, and the naked-eye 3D display effect is observed through the grating glass 6 to ensure that the grating distortion is effectively corrected. After the correction is completed, the rotation knob 9 is pushed to disengage the locking block 15 from the locking slot 17 to prevent the threaded rod 11 from rotating due to accidental contact by the staff, which would cause the distance between the adjustment frame 3 and the grating glass 6 to change and affect the display effect.
