Description

Technical Field

[0001] The invention relates to the field of 3D virtual display screens, and in particular to an inner curved display screen with rotating imaging. Background Art

[0002] There are many ways to present virtual reality images. As a holographic display technology, the current main method is a rotating imaging plane similar to a rotating fan. When the imaging plane is large, the part of the image displayed away from the observer will be visually distorted to the observer. If the image is displayed in an arc with the observer as the center or approximately at the center, the observer's visual experience will be better than that of a flat screen. This is similar to the visual difference between the flat-panel displays and curved screen displays that we often use.

[0003] Therefore, the display technology that can produce a larger curved surface at a low cost is a technical problem that needs to be solved at present. Summary of the invention

[0023] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0024] like Figure 1-3 As shown, a rotating imaging inner arc display screen proposed by the present invention comprises a base 1, a rotating mechanism 3 and a light-emitting rotating arm;

[0025] A driving motor is provided inside the base 1 for driving the rotating mechanism 3 to rotate in a circle on a horizontal plane; the rotating mechanism 3 is connected to the light-emitting rotating arm;

[0026] One or more groups of luminous rotating arms are provided, and each luminous rotating arm is located in a different vertical plane; the luminous rotating arm comprises a rotating arm 5 and a light belt 6; the light belt 6 is provided on the inner peripheral side wall of the rotating arm 5, and the illumination direction of the light belt 6 is horizontally toward the central axis of the rotating center;

[0027] A control system is provided inside the base 1 for controlling the on / off, brightness change and color change of each LED lamp bead.

[0028] In an optional embodiment, the tops of one or more groups of light-emitting rotating arms are connected, and the connection is located on the central axis of rotation; a fixing part 4 is arranged on the rotating mechanism 3; a blind hole with a thread is arranged on the fixing part 4, and the bottom of the rotating arm 5 is installed on the fixing part 4 by bolts; the light strip 6 includes a plurality of LED lamp beads; a protective shell is arranged on the periphery of the base 1 and the rotating mechanism 3.

[0029] In an optional embodiment, the control system includes a control mainboard 21 and a control chip; the control chip controls the connection to the control mainboard 21; the control mainboard 21 is integrated with a power control circuit, a power wireless transmission circuit, a light strip display control circuit and a wireless data transmission circuit.

[0030] In the present invention, the illumination direction of multiple LED lamp beads is horizontally toward the central axis of the rotation center; the control system is used to control the on / off, brightness change and color change of each LED lamp bead. These changes will present a display picture effect similar to a curved screen to the observer's vision, forming an imaging effect of an inner arc display screen in human vision.

[0031] In the present invention, the main structure and image forming principle are similar to those of the existing flat display rotating display screen. The main difference lies in the form, structure and related processes of the rotating arm 5. In the present device, the rotating arm 5 is arc-shaped or semicircular, and the outer peripheral surfaces of multiple groups of rotating arms 5 are located on the same ellipsoidal surface or spherical surface. The multiple groups of rotating arms 5 are located in different vertical planes. Therefore, there will be no problem of blocking the line of sight, and the patternless vertical bars caused by the blocking problem of the luminous rotating arm itself are avoided, so as to avoid the visual feeling of the screen being divided in the human body.

[0032] It should be noted that the image seen by human eyes will be the display screen of the inner arc sphere of the rotating arm 5 and the light strip 6;

[0033] Therefore, the rotating arm 5 is designed to be a straight line at a certain distance from the rotation axis, and the light direction of the light strip still tends to be toward the rotation axis, and the picture seen by the human eye will be a display screen of the inner arc cylinder; wherein, the rotating arm 5 is designed to be a curve at a certain distance from the rotation axis, and the picture seen by the human eye will also be a display screen with different effects according to the style of the curve.

[0034] In summary, the present invention utilizes the visual delay of the human eye to the light changes of the light strip 6, uses fewer light strips 6 to cooperate with high-speed rotation and during the rotation of the light-emitting lamp, the control system controls the on / off, brightness change and color change of each LED lamp bead, thereby making the light strip 6 on the rotation trajectory constitute a large inner arc display screen with an effect similar to a curved display screen.

[0035] In an optional embodiment, a protective shell is provided on the periphery of the base 1 and the rotating mechanism 3, which has a good protective effect and is safe to use.

[0036] In an optional embodiment, a colorless and transparent protective cover is provided on the outside of the light strip 6, which makes it safer to use.

[0037] In an optional embodiment, the light strip 6 includes a flexible circuit that is signal- and electrically connected to the control system, and a plurality of LED lamp beads are electrically connected in parallel on the flexible circuit.

[0038] In an optional embodiment, the rotating mechanism 3 includes a rotating member 2; the driving motor power is connected to the rotating output shaft 10, and the rotating output shaft 10 is key-connected to the rotating member 2; the bottom of the light strip 6 and the bottom of the rotating arm 5 are both fixed to the rotating member 2 and the fixing member 4 by bolts; the control main board 21 is arranged at the bottom of the rotating member 2; a power wireless transmission control board 11, a wireless magnetic induction primary coil 12 and a spotlight-type light-emitting lamp 13 are arranged inside the base 1; the power wireless transmission control board 11 is installed above the base 1, and the power wireless transmission control board 11 is electrically connected to an external power supply; the wireless magnetic induction primary coil 12 and the spotlight-type light-emitting lamp 13 are both arranged on the power wireless transmission control board 11; a wireless magnetic induction secondary coil 22 is arranged below the control main board 21; the wireless magnetic induction secondary coil 22 is arranged corresponding to the wireless magnetic induction primary coil 12; a photosensitive sensor 23 is arranged below the control main board 21; the photosensitive sensor 23 is arranged corresponding to the spotlight-type light-emitting lamp 13; the control circuit of the spotlight-type light-emitting lamp 13 is electrically connected to the control main board 21 via a flexible wire.

[0039] It should be noted that, during operation, the drive motor is started by power supply from an external circuit or controlled by a switch, and the drive motor drives the rotating mechanism 3 to rotate at a high speed, and the rotating mechanism 3 further drives the rotating arm 5 to rotate.

[0040] At the same time, the wireless power transmission control circuit transmits power to the control mainboard 21. The control mainboard 21 receives external image or video data through the integrated wireless data transmission circuit, or reads the data stored in the control chip, and sends it to the display control circuit, which converts it into an electrical signal for controlling the display of the light strip. At the same time, the light sensor 23 is used to determine the rotation speed of the rotating arm 5 and the position of the light strip 6, so that each LED lamp bead on the light strip 6 displays the content according to the predetermined picture, so as to change the brightness and color of the LED lamp beads during rotation, so as to present a rotating dynamic imaging picture.

[0041] Since the light strip 6 is arranged on the inner side of the rotating arm 5, the light direction of the light strip 6 is horizontally toward the central axis of the rotating center, and the human eye is viewing from the outer side of the rotating arm 5, what the human eye sees is a large inner curved display screen similar to a computer curved display.

[0042] In an optional embodiment, a vertically downward cylinder is provided on the lower surface of the fixing member 4, and a threaded blind hole A is provided at the bottom of the cylinder from bottom to top along the axial direction; a through hole for the cylinder to pass through is provided on the bottom of the light strip 6 and the rotating arm 5; a through hole B is provided on the rotating member 2; a bolt passes through the through hole B and is screwed into the threaded blind hole A to fix the fixing member 4 on the rotating member 2; the bottom of the light strip 6 and the rotating arm 5 are clamped between the fixing member 4 and the rotating member 2.

[0043] It should be noted that the installation structure of the light strip 6 and the rotating arm 5 is stable and safe to use.
