Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The rotary spliced screen is mainly formed by splicing a plurality of display units, a splicing seam which cannot be displayed is formed between every two adjacent display units, the rotary spliced screen specifically comprises a central display unit in the middle and side display units positioned at two ends of the central display unit, the rotating center of the rotary spliced screen is positioned on the central display unit, the central display unit rotates along a preset direction to drive the side display units arranged on the first side and the second side opposite to the central display unit in a splicing mode to rotate, in the process of rapidly rotating the rotary spliced screen, display pictures in all the display units are changed in real time, different picture combinations displayed by the spliced screen at different rotating positions and different moments are combined, and therefore continuous display pictures are formed on a circular display surface formed by rotation.
The central display unit and/or each side display unit comprises at least one sub-display area used for performing brightness compensation on the splicing seams on the opposite side, and each splicing seam on one side of the rotation center is rotationally symmetrical with one sub-display area on the other side of the rotation center about the rotation center, so that each splicing seam has a corresponding sub-display area for performing brightness compensation on the splicing seams in the rotation process. Therefore, the rotation track of a certain sub-display area on one side of the rotation center coincides with the rotation track of the splicing seam on the other side of the rotation center, namely, the rotary splicing screens on the two opposite sides of the rotation center can realize complementation, so that the dark area which cannot be displayed on the splicing seam on each side can be subjected to brightness compensation through the display area on the opposite side, and image missing or discontinuity caused by overlapping of the dark areas on the two sides is avoided. The inventive idea is further explained below in several different embodiments to enable a person skilled in the art to better understand the invention.
Example 1
Referring to fig. 2 and 3, the rotary type tiled display screen of the present embodiment includes a central display unit 10 rotating along a predetermined direction and side display units (not shown) tiled on two opposite first sides (i.e. left side shown in fig. 2) and second sides (i.e. right side shown in fig. 2) of the central display unit 10, wherein a rotation center O of the rotary type tiled display screen is located on the central display unit 10; the splicing seams comprise a first splicing seam 100 positioned on the first side of the rotation center O and a second splicing seam 200 positioned on the second side of the rotation center O, the sub-display areas used for performing brightness compensation on the splicing seams on the opposite sides comprise a first display area D1 positioned on the first side of the rotation center O and a second display area D2 positioned on the second side of the rotation center O, and the rotation track of the second display area D2 in at least one display unit positioned on the second side of the rotation center O is superposed with the rotation track of the first splicing seam 100 positioned on the first side of the rotation center O; the rotational trajectory of the first display area D1 in the at least one display unit located on the first side of the rotational center O coincides with the rotational trajectory of the second splice seam 200 located on the second side of the rotational center O.
In this embodiment, the side display units are mainly the first display units 21, the first side and the second side of the central display unit 10 are respectively provided with one first display unit 21 in a splicing manner, and the central display unit 10 and the first display units 21 are arranged along a straight line. The first display unit 21 is preferably equal in width to the central display unit 10. Distances between the splicing seams located on the first side and the second side of the rotation center O and the rotation center O are different, that is, a distance a from the first splicing seam 100 to the rotation center O is not equal to a distance b from the second splicing seam 200 to the rotation center O, and fig. 3 shows a case where b > a, total lengths of the display units located on the first side and the second side of the rotation center O are preferably equal, that is, the length of the first display unit 21 located on the first side of the rotation center O is greater than that of the first display unit 21 on the opposite side, so that lengths of the display screens on both sides are symmetrical with respect to the rotation center O.
It is understood that, in other embodiments, the first side and the second side of the central display unit 10 may also be respectively provided with a plurality of first display units 21, and the central display unit 10 is aligned with all the first display units 21. The distance from any splicing seam between two adjacent display units positioned on the first side of the rotation center O to the rotation center O is unequal to the distance from any splicing seam between two adjacent display units positioned on the second side of the rotation center O to the rotation center O, so that no shadow overlapping area exists in the splicing seam areas on the two sides of the rotation center O in the rotating process, and the splicing seams on the first side and the second side are asymmetrically arranged relative to the rotation center O. Further preferably, the total lengths of the rotary spliced screens positioned on the first side and the second side of the rotation center O are also equal, so that the parts on the two sides of the rotation center O of the rotary spliced screen are stressed symmetrically in the rotation process, and the rotation is stable.
When the rotary spliced screen rotates around the rotation center O rapidly, the pictures displayed in the center display unit 10 and the first display unit 21 change correspondingly, the first dark area formed in the rotation process of the first side splicing seam and the second dark area formed by the second side splicing seam are unequal in distance from the rotation position of the center, so that an overlapped dark area cannot be formed, image display can be performed through the display area of the display dark area by means of other rotations, the brightness compensation is performed, the display brightness of the dark area is consistent with the whole brightness after the rotation, and the purpose of displaying image content in the circular display area completely is achieved.
Example 2
As shown in fig. 4, different from embodiment 1, the side display unit of this embodiment further includes a plurality of second display units 22, and in embodiment 1, every two adjacent display units are further simultaneously connected to one second display unit 22, that is, the center display unit 10 and the first display unit 21 are simultaneously connected to one second display unit 22, and every two first display units 21 are simultaneously connected to one second display unit 22, as shown in fig. 4, the first display unit 21 and the center display unit 10 are connected in the length direction of the display units (e.g., left and right directions in fig. 4), and the second display unit 22 is connected to the center display unit 10 and the first display unit 21 in the width direction of the display units (e.g., up and down directions in fig. 4). It is understood that there may be a plurality of first display units 21 on both sides of the rotation center O, and the first display units 21 may be spliced with the first display units 21 in the length direction of the display units.
Because the second display unit 22 is spliced and arranged beside the splicing seams between the central display unit 10 and the first display unit 21 and between the first display unit 21 and the first display unit 21, when the rotary spliced screen rotates around the rotation center O rapidly, the second display unit 22 can perform brightness compensation on the splicing seams, the distances from the splicing seams on the two sides of the central display unit 10 to the rotation center O can be set to be equal or unequal, and the phenomenon of shadow overlapping can not occur.
In other embodiments, the second display units 22 on both sides of the rotation center O may be further disposed not to be rotationally symmetric about the rotation center O nor symmetric about the symmetry axis of the center display unit 10, and a distance from each second display unit 22 located on a first side of the rotation center O to the rotation center O is different from a distance from each second display unit 22 located on a second side of the rotation center O to the rotation center O. On one hand, the sub-display regions on the first side and the second side of the rotation center O respectively perform brightness compensation on the splicing seams on the opposite sides in the process of rotating around the rotation center O, and on the other hand, the second display units 22 on the first side and the second side of the rotation center O also respectively perform brightness compensation on the splicing seams on the opposite sides in the process of rotating around the rotation center O, so that the compensation effect can be ensured.
Further, the second display units 22 located at the first and second sides of the rotation center O are asymmetrically disposed. For example, as shown in fig. 4, the second display units 22 located at the first side and the second side of the rotation center O are respectively located at two different sides of the rotation direction of the rotary type spliced screen (one of the second display units 22 is located above the first side, and one of the second display units 22 is located below the second side); alternatively, the second display units 22 located at the first side and the second side of the rotation center O are alternately tiled at two different sides (upper and lower sides of fig. 4) in the width direction of the first display unit 21, that is, the arrangement of the second display units 22 is in an arrangement of "… up-down-up-down …" with respect to the rotation center O, so that the uniformity of the image brightness is better during the rotation of the rotary tiled screen around the rotation center O.
The tracks of the splicing seams formed by the display units at the two ends of the rotary splicing screen are not overlapped in the rotating process, so that an overlapped dark area cannot be formed, and the brightness compensation can be performed by using other non-splicing seam areas of the display units, so that the display brightness of the dark area is consistent with the integral brightness after rotation, and the complete display of the image content in the circular display area is realized.
The foregoing is directed to embodiments of the present application and it is noted that numerous modifications and adaptations may be made by those skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
