[0028] The embodiments of the present application provide a spliced display device and a vehicle, which will be described below in conjunction with the accompanying drawings Figures 1 to 4 The embodiments of the spliced display device and the vehicle will be described.

[0029] Please refer to Figures 1 to 2The embodiment of the present application provides a spliced display device, which comprises a spliced screen, a third panel 5, a connecting piece 3 and a convex lens 4.

[0030] The spliced display device comprises the spliced screen, the third panel 5, the connecting piece 3 and the convex lens 4, the third panel 5 at the target position is arranged below the interval between the first panel 1 and the second panel 2 of the spliced screen, and the light emitted by the third panel 5 at the target position can pass through the convex lens 4, so that the picture of the third panel 5 is enlarged through the convex lens 4 arranged in the interval between the first panel 1 and the second panel 2, that is, at the interval, the picture of the third panel 5 enlarged through the convex lens 4 can be seen by the human eye, and the picture of the third panel 5 enlarged through the convex lens 4 can be matched with the pictures displayed by the first panel 1 and the second panel 2, so that the spliced display device realizes seamless display between the first panel 1 and the second panel 2 through the convex lens 4 and the third panel 5, the display effect of the spliced display device is improved, the use experience of the user is improved, and the use performance of the spliced display device is improved.

[0031] According to actual needs, one or more first panels 1 and one or more second panels 2 can be arranged, and the convex lens 4 can be arranged corresponding to the interval between the at least one first panel 1 and the second panel 2.

[0032] In the embodiment, the target position refers to the position of the third panel 5 after the third panel 5 is adjusted according to the viewing position of the user. Further, when the third panel 5 is at the target position, the picture seen by the human eye from the side, away from the third panel 5, of the convex lens 4 is enlarged, the display at the interval between the first panel 1 and the second panel 2 is realized, and the display has no boundary feeling.

[0033] Optionally, the spliced display device further comprises the connecting piece 3, the connecting piece 3 is arranged in the interval between the first panel 1 and the second panel 2, and the connecting piece 3 is connected with the first panel 1 and the second panel 2 respectively; the connecting piece 3 comprises an opening, and the convex lens 4 is arranged in the opening. When a plurality of convex lenses 4 are arranged in an interval, a plurality of openings can be arranged on the connecting piece 3, and the plurality of convex lenses 4 are arranged in the plurality of openings one by one.

[0034] In the embodiment, the first panel 1 and the second panel 2 are fixedly connected through the connecting piece 3, the connecting piece 3 can be made of plastic, acrylic or the like, and in order to fix the convex lens 4, corresponding openings can be arranged on the connecting piece 3 to place the convex lens 4.

[0035] It can be understood that, in the embodiment, by adjusting the distance between the convex lens 4 and the third panel 5, the picture of the third panel 5 can be enlarged by the convex lens 4, that is, the picture seen by the human eye from the side of the convex lens 4 away from the third panel 5 is enlarged, and then the display at the interval between the first panel 1 and the second panel 2 is realized, so that the display has no border feeling.

[0036] Optionally, the first panel 1, the second panel 2 and the third panel 5 can be organic light-emitting diode (OLED) display panels, quantum dot light-emitting diodes (QLED) or micro flat display panels (Micro-OLED or Micro-LED) and the like.

[0037] The spliced display device provided by the embodiment of the application can be applied to a vehicle-mounted display, and can also be applied to any electronic product with a display function, including but not limited to the following categories: mobile phones, televisions, notebook computers, desktop displays, tablet computers, digital cameras, smart wristbands, smart glasses, medical devices, industrial control devices, touch interactive terminals and the like, and the embodiment of the application does not specially limit this.

[0038] It should be noted that, since the picture enlarged by the convex lens 4 is reversed relative to the display picture of the third panel 5, that is, the up and down and the left and right of the two pictures are opposite, in order to make the picture enlarged by the convex lens 4 match the pictures of the first panel 1 and the second panel 2, the display picture of the third panel 5 can be reversed relative to the pictures of the first panel 1 and the second panel 2, so that the picture enlarged by the convex lens 4 can have the same setting direction as the pictures of the first panel 1 and the second panel 2.

[0039] Considering that the picture enlarged by the convex lens 4 can match the pictures of the first panel 1 and the second panel 2, the matching means that, on the one hand, the picture enlarged by the convex lens 4 can match the specific content displayed by the pictures of the first panel 1 and the second panel 2, and on the other hand, the picture enlarged by the convex lens 4 can have the same resolution as the pictures of the first panel 1 and the second panel 2, therefore, in order to realize that the picture enlarged by the convex lens 4 has the same resolution as the pictures of the first panel 1 and the second panel 2, in some optional embodiments, the pixel density of the third panel 5 is greater than the pixel density of the first panel 1 and the second panel 2.

[0040] It can be understood that the pixel density difference between the pixel density of the third panel 5 and the pixel density of the first panel 1 and the second panel 2 needs to be matched with the magnification of the convex lens 4, for example, when the magnification of the convex lens 4 is 2 times, the pixel density of the third panel 5 needs to be greater than the pixel density of the first panel 1 and the second panel 2, so that the pixel density of the picture magnified by the convex lens 4 can be consistent with the pixel density of the first panel 1 and the second panel 2, so as to eliminate the difference between the picture magnified by the convex lens 4 and the picture of the first panel 1 and the second panel 2, and improve the display effect.

[0041] Optionally, the pixel density of the first panel 1 and the pixel density of the second panel 2 are the same, so as to avoid the difference between the picture of the first panel 1 and the picture of the second panel 2, and improve the display effect.

[0042] Please refer to Figure 1 and Figure 3 In some optional embodiments, the spliced display device further comprises a rotating member 6, the rotating member 6 is connected with the third panel 5, so as to adjust the included angle between the light exit surface of the third panel 5 and the light exit surface of the first panel 1.

[0043] Considering that the user may view the spliced display device from different positions, that is, the viewing angle of the user relative to the spliced display device is different, and the picture magnified by the convex lens 4 seen by the user is also different, in the embodiment, the position of the third panel 5 can be adjusted according to the viewing angle of the user, that is, the third panel 5 is driven by the rotating member 6 to rotate relative to the first panel 1 and the second panel 2, so as to adjust the included angle between the light exit surface of the third panel 5 and the light exit surface of the first panel 1 and the second panel 2, as shown in Figure 3 , so as to adjust the picture magnified by the convex lens 4, so that the first panel 1 and the second panel 2 are seamlessly displayed under the viewing angle of the user.

[0044] In the embodiment, the rotating member 6 can adopt a rotating shaft or the like, and the extension direction of the rotating member 6 can be the same as the extension direction of the interval between the first panel 1 and the second panel 2, so that the third panel 5 can be rotated towards the direction close to or away from the first panel 1 (or the second panel 2).

[0045] In some optional embodiments, the spliced display device further comprises a moving member 7, the moving member 7 is connected with the third panel 5, so as to drive the third panel 5 to move along the thickness direction of the spliced display device and / or the direction perpendicular to the thickness direction of the spliced display device.

[0046] It should be noted that by setting the moving piece 7 to drive the third panel 5 to move in the horizontal direction and / or the vertical direction, on the one hand, the enlarged picture of the convex lens 4 can be adjusted, and on the other hand, since the convex lens 4 has a condensing effect, in order to prevent damage to the third panel 5 caused by external light, when the third panel 5 is not in use, the third panel 5 can be moved away by the moving piece 7, so that the light emitted by the convex lens 4 does not irradiate the third panel 5, thereby improving the service life of the tiled display device.

[0047] Optionally, the moving piece 7 includes a sliding rail 71 and a fixing piece 72 moving along the sliding rail 71, the third panel 5 is connected with the fixing piece 72, and the sliding rail 71 extends along the horizontal plane. The third panel 5 moves along the rail in the horizontal plane through the fixing piece 72. Of course, according to actual needs, the sliding rail 71 can also extend along the thickness direction of the tiled display device, and there is no special limitation.

[0048] Optionally, the moving piece 7 is connected with the rotating piece 6 to drive the rotating piece 6 to move together, so as to facilitate the stable connection between the rotating piece 6 and the third panel 5.

[0049] Please refer to Figure 3 In some optional embodiments, the tiled display device further includes an anti-reflection layer 9, which is arranged on the surface of the convex lens 4 away from the third panel 5.

[0050] It can be understood that by arranging the anti-reflection layer 9, the anti-reflection layer 9 can be used to reduce the light transmission of the convex lens 4, increase the reflected light, and thereby reduce the amount of light irradiated to the third panel 5 by external light, avoid damage to the third panel 5 by the light converging by the convex lens 4, and improve the reliability and service life of the tiled display device.

[0051] Specifically, the anti-reflection layer 9 can be a kind of surface coating film, which can increase the reflectivity of optical devices, that is, the ability of light reflection. The working principle of the anti-reflection layer 9 is also based on the interference phenomenon, that is, by adding an appropriate medium in the path of light propagation, the interference between adjacent light waves is formed, thereby enhancing the ability of reflection.

[0052] According to actual needs, the anti-reflection layer 9 can include one or more optical film layers, which can be designed according to actual needs, and there is no special limitation.

[0053] In some optional embodiments, a plurality of convex lenses 4 are arranged along the extension direction of the interval.

[0054] It should be noted that, since the convex lens 4 is generally in a circular or oval shape, and the specific shape of the convex lens 4 will also affect the enlarged picture, in order to facilitate the adjustment of the enlarged picture and ensure that the enlarged picture meets the requirements, a plurality of convex lenses 4 can be arranged in the interval between the first panel 1 and the second panel 2, the convex lenses 4 do not interfere with each other, and the pictures of the third panel 5 at different positions can be enlarged, that is, a plurality of picture areas can be correspondingly arranged on the third panel 5, and correspond to different convex lenses 4.

[0055] It should be noted that the number of convex lenses 4 and the specific size of the convex lens 4 can be selected according to the actual interval size between the first panel 1 and the second panel 2, as long as the display at the interval between the first panel 1 and the second panel 2 is ensured, and the display has no border feeling.

[0056] Optionally, along the extension direction of the interval, the distance between adjacent convex lenses 4 is equal.

[0057] It can be understood that, by setting the distance between adjacent convex lenses 4 to be equal, the uniformity of the display picture at the interval between the first panel 1 and the second panel 2 is improved, the display effect is improved, and the convex lens 4 is also convenient to set. The distance between adjacent convex lenses 4 should not be too large, otherwise it may cause a gap between the pictures displayed by adjacent convex lenses 4, affecting the display effect.

[0058] In some optional embodiments, the spliced display device further comprises an eye movement recognition member 8 arranged on the first panel 1 and / or the second panel 2. The eye movement recognition member 8 is configured to obtain the relative position relationship between the human eye and the first panel 1 or the second panel 2, so as to control the third panel 5 to rotate or move relative to the first panel 1 according to the relative position relationship, for example, the third panel 5 can be controlled to rotate or move to the above-mentioned target position.

[0059] In the present embodiment, on the one hand, the eye movement recognition member 8 can identify the distance between the human eye and the first panel 1 or the second panel 2, and on the other hand, the eye movement recognition member 8 can also identify the relative direction between the human eye and the first panel 1 or the second panel 2, for example, it can be judged that the user looks at the spliced display device from the left side, the middle or the right side of the first panel 1 or the second panel 2, so as to control the third panel 5 to rotate or move relative to the first panel 1 through a controller (such as a chip) and the like Control element, so that the user at different positions can also watch the seamless spliced display device, and ensure the user experience.

[0060] It should be noted that the eye movement recognition technology detects a person's eyeball in real time and tracks what they are looking at. The technology converts the eyeball movement into a data stream, which contains information such as pupil position, gaze direction of each eye, and gaze focus. In essence, the technology detects the eyeball and replaces the traditional input signal (such as manual input, voice, motion recognition, etc.) with the corresponding signal. In the present embodiment, the eye movement recognition device 8 can be used to control the spliced display device. For example, in a vehicle, the driver's command can be recognized, and the spliced display device can be controlled to turn on or off according to the movement of the user's eyeball.

[0061] In some optional embodiments, the color of the connecting piece 3 is the same as the screen-off color of the first panel 1 and the second panel 2, that is, the connecting piece 3 can be made of black material, so that the first panel 1 and the second panel 2 are clearly visible when the screen is on, and the first panel 1 and the second panel 2 are integrated with the connecting piece 3 when the screen is off, without color difference, to achieve an integrated black effect and improve the user's experience.

[0062] Optionally, the spacing between the third panel 5 and the first panel 1 and the second panel 2 in the thickness direction of the spliced display device is overlapped, so that the size of the third panel 5 is greater than or equal to the size of the spacing between the first panel 1 and the second panel 2. In order to facilitate the focusing and magnification of the convex lens 4 on the picture of the third panel 5, the size of the third panel 5 can be set to be relatively large.

[0063] The embodiment of the present application also provides a vehicle comprising the spliced display device in any of the above embodiments.

[0064] The vehicle provided by the embodiment of the present application can be internally provided with a spliced display device to meet the display requirements.

[0065] The vehicle provided by the embodiment of the present application has the technical effects of the technical solutions of the spliced display device in any of the above embodiments, and the same or corresponding structures and explanations of the terms are not repeated here.

[0066] The above is only a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-described system, module and unit can refer to the corresponding process in the foregoing method embodiments, which will not be described here. It should be understood that the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application.
