Description

Technical Field

[0001] The present invention relates to the technical field of 3D glasses, in particular to a pair of naked-eye 3D parallel glasses. Background Art

[0002] 3D glasses generally include chromatic aberration, time-division, polarized light, and flicker-free types.

[0003] Chromatic aberration, also known as color separation stereo imaging technology, uses two images taken from different viewing angles to print them in two different colors on the same screen. If viewed with the naked eye, it will appear as a blurry double image. The stereo effect can only be seen through the corresponding red and blue stereo glasses, which is to filter the red and blue colors. The red image passes through the red lens and the blue passes through the blue lens. The different images seen by the two eyes overlap in the brain to present a 3D stereo effect.

[0004] Time-division 3D glasses are also called active shutter 3D glasses. Shutter 3D technology can provide high-quality 3D display effects for home users. The implementation of this technology requires a pair of active LCD shutter glasses, which alternate the images seen by the left eye and the right eye so that the brain merges the two images into one, thereby producing a 3D depth sense of a single image.

[0005] Polarized 3D technology is now widely used in commercial cinemas and other high-end applications. The technology is the same as the shutter type, but the difference is that it is passively received, so it is also called passive 3D technology. The cost of auxiliary equipment is low, but the requirements for output equipment are high, so it is very suitable for commercial cinemas and other places that require a large number of audiences.

[0006] The flicker-free method separates the left and right images through the TV and sends them to the glasses at the same time. The separated left and right images are filtered by the glasses and sent to each eye. The brain then combines the two images to give people a 3D sense.

[0007] Naked-eye 3D is a general term for technologies that achieve stereoscopic visual effects without the help of external tools such as polarized glasses. From a technical point of view, naked-eye 3D can be divided into three types: light barrier type, cylindrical lens technology and directional light source. Generally, high-tech display equipment is required to achieve this.

[0008] The realization of the 3D effect of the above 3D glasses requires special lenses and display devices to cooperate with each other, while the visual effect of naked-eye 3D requires high-tech display devices. These tools are expensive and are generally used in the commercial field. For ordinary people, it is difficult to achieve the 3D effect when watching TV series on mobile phones in daily life. There are currently no 3D glasses for mobile phone videos on the market.

[0009] The principle of binocular imaging is that when a normal eye looks far or near, it can see a clear image. This is because the lens itself is an elastic body, and the muscles around it can adjust the curvature of its surface according to the distance of the object, thereby changing the focal length of the eye and allowing the object to be imaged on the retina. Due to the difference in normal pupil distance and gaze angle, there is a certain degree of horizontal difference in the image of the left and right eye retinas. When observing stereoscopic sight marks, the two eyes are about 60mm apart, so they will observe from different angles. This tiny horizontal image difference in the image of the binocular retina is called stereoscopic parallax, and after being synthesized by the brain, there is a sense of three-dimensionality. Parallel eye 3D uses the principle of left and right eye parallax imaging to simulate the way the left and right eyes observe the same object from different angles, display two pictures, and then use the eyes to watch the pictures on both sides respectively, the left eye looks at the picture on the left, and the right eye looks at the picture on the right. In this way, the imaging effect of the human eye looking at three-dimensional objects is achieved, and even facing the mobile phone screen, you can experience the visual effect of naked eye 3D.

[0010] Therefore, we propose a naked-eye 3D parallel glasses to solve the above-mentioned problems.

[0045] Two groups of lens barrels 7 are symmetrically arranged on the left and right sides of the partition 6, and the lens barrel 7 is rotatably connected to the head-mounted frame 2 through an upper rotating shaft 10 and a lower rotating shaft 11, and the upper rotating shaft 10 and the lower rotating shaft 11 are both perpendicular to the central axis of the lens barrel 7.

[0046] The spacing adjustment mechanism is used to adjust the spacing between the two sets of lens barrels 7. The lens barrels 7 are slowly gathered together through the spacing adjustment mechanism, and after the brain synthesizes a picture, there is a three-dimensional sense, realizing a 3D visual effect.

[0047] The clamping plate 24 is slidably installed in the rear cavity 5 through a sliding assembly. The clamping plate 24 is used to fix the mobile phone and is suitable for different mobile phone models. The clamping plate 24 refers to the mobile phone clamping device in the prior art, such as the bedside mobile phone clamping bracket.

[0048] The distance adjustment mechanism is used to adjust the distance between the clamping plate 24 and the lens barrel 7. Adjusting the distance between the clamping plate 24 and the lens barrel 7, that is, adjusting the distance between the mobile phone and the lens barrel 7, is used to meet different viewing distance requirements.

[0050] In another embodiment of the present invention, see Figure 2 , Figure 5 , Figure 6 The spacing adjustment mechanism includes a rotating rod 12, which is rotatably connected to a fixed block 14 at the bottom of the main housing 1 through a stopper 13 in the middle to ensure that the position of the rotating rod 12 does not change and only rotates in the original position. The rotating rod 12 is symmetrically provided with a first threaded portion 16 and a second threaded portion 17, which are positive and negative threads.

There is a certain friction between the connecting rod 23 and the connecting sleeve 25, and human power is required to rotate, and it will not rotate by itself.

[0054] In another embodiment of the present invention, see Figure 7-Figure 9 The distance adjustment mechanism includes a screw rod 26 rotatably mounted on the bottom wall of the rear cavity 5 through a mounting plate 27, a second movable block 29 is threadedly connected to the screw rod 26, and the sliding mounting blocks 22 are connected to both sides of the second movable block 29 through a linkage rod 30.

[0055] During specific implementation, by rotating the second knob 28, the screw rod 26 rotates, driving the second movable block 29 to move on the screw rod 26, thereby driving the sliding mounting block 22 and the clamping plate 24 to move through the linkage rod 30, the second movable block 29 moves forward along the guide rail 31, and the sliding mounting block 22 moves forward along the slide rail 21, thereby adjusting the distance between the mobile phone and the lens barrel 7.

[0056] Working principle: When using the naked-eye 3D parallel glasses, first, the user fixes the mobile phone on the clamping plate 24, then rotates the clamping plate 24 around the connecting rod 23 to face inward, and then closes the rear cover 3. Wear the head-mounted frame 2 through the fixing strap 9, align the eyes with the two lens barrels 7, and adjust the tightness through the adjustment buckle 901.
