In order to meet the requirement of splicing display of display panels, the existing splicing technology focuses on reducing the frame of the display device so as to reduce the splicing side seam between the display devices as much as possible, so that the spliced display devices can have better and continuous display effects.
However, as long as the display device has a physical splicing seam, the display device must process the splicing seam when performing splicing display, and the processing procedure generally includes: clipping the image side seams aiming at the splicing side seams to ensure that the display picture can have continuous display effect at the splicing side seams; due to the clipping of the display screen, a part of the algorithm needs to be specially processed at the splicing position, for example, firstly, the image enhancement algorithm processing is performed on the display image containing the size of the splicing seam, and then the cutting of the display seam and the image joining are performed. In addition, on the premise that the display side seam is not cut, although the display mode of the spliced image can be simplified, an obvious image displacement effect is formed at the display side seam, and the displayed image has obvious discontinuity.
Therefore, when the existing display device performs the tiled display, besides increasing the difficulty of the display content processing and the actual operation of the image synergy algorithm, the corresponding processing is required to be performed each time the size of the tiled edge seam changes, so that the content of the display image can have better continuity at the display edge seam, but the loss of the image content cut at the display edge seam cannot be avoided.

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.
Example 1
Referring to fig. 1 and fig. 2a, the tiled display device according to the embodiment of the present invention mainly includes at least two sub-display units 10 tiled together and a first brightness compensation unit 21, the tiled display device has a sub-display area a corresponding to the display surface of each sub-display unit 10, a first non-display area B1 corresponding to the tiled joint between two adjacent sub-display units 10, and a first compensation area C1 disposed close to and parallel to the first non-display area B1 in the sub-display area a, in this embodiment, the first compensation area C1 is connected to the splicing seam, and the width of the first compensation area C1 is not less than the first non-display area B1, the splicing display device moves back and forth along the predetermined path of the display surface, and the first compensation area C1 is used for covering the dark area picture formed by the movement of the first non-display area B1 during the movement of the splicing display device. The first brightness compensation unit 21 is configured to control brightness enhancement of the first compensation region C1 when the first compensation region C1 covers a dark area picture formed by moving the first non-display region B1, and brightness of the dark area picture of the first non-display region B1 after compensation is consistent with brightness of the sub-display region a, so that a shadow generated during a fast moving process of the splicing seam region can be eliminated.
In addition to the first luminance compensation unit 21 for compensating the luminance of the first non-display area B1 corresponding to the joint line, the tiled display device further includes a second luminance compensation unit 22, and the sub-display area a further includes a second compensation area C2 close to the frame of the sub-display unit 10, in this embodiment, preferably, the second compensation area C2 is connected to the frame of the sub-display unit 10, the second compensation area C2 is used for covering the dark area picture formed by the frame movement of the sub-display unit 10 during the movement of the tiled display device, the second luminance compensation unit 22 is used for controlling the luminance enhancement of the second compensation area C2 when the second compensation area C2 covers the dark area picture formed by the frame movement of the sub-display unit 10, and the luminance of the dark area picture of the second non-display area B2 after compensation is consistent with the luminance of the sub-display area a, so as to compensate the luminance of the second non-display area B2 corresponding to the frame on the sub-display unit 10.
Because the brightness of the first compensation area C1 and the second compensation area C2 is higher than that of other areas, in the moving process of the tiled display device, the first compensation area C1 on the left side of the tiled seam compensates the adjacent first non-display area B1, and the second compensation area C2 of the sub-display unit 10 compensates the second non-display area B2, so that the influence of the tiled seam and the frame on the continuity of the display screen can be eliminated to a certain extent. The present embodiment has a first compensation zone C1 on only one side of the splice seam. In other embodiments, two first compensation regions C1 may be provided on each side of the splice seam, and two first compensation regions C1 compensate for the adjacent first non-display region B1 at the same time.
The present invention takes into account that when human eyes watch a rapidly moving image, the impression of the optic nerve on the watched image does not disappear immediately after the image disappears. Therefore, as shown in fig. 2a and fig. 2b, in this embodiment, all the sub-display units 10 of the tiled display device are preferably arranged linearly, and in the moving process, the corresponding pictures of each sub-display unit 10 are also designed to change from frame to frame along with the moving process, so that the frame picture currently displayed by the display unit and the previous frame picture are combined into a new display picture, and thus the tiled display device is continuously moved, the display area of the new display picture observed by the human eye is the combined area of the previous and next multi-frame pictures that cannot be perceived by the human eye, when persistence of vision needs to be realized, the tiled display device needs to be moved faster, and the image switching speed of each sub-display unit 10 is not less than 1/24 seconds per frame, so that the frame picture of persistence of vision and the current frame picture are perfectly combined. In the process of refreshing the picture, the first non-display area B1 corresponding to the joint seam between the sub-display units 10 is subjected to brightness compensation, so that the brightness of the first non-display area B1 is consistent with other areas, and the second non-display area B2 corresponding to the frame of each sub-display unit 10 is also subjected to brightness compensation, so that the brightness of the second non-display area B2 is also consistent with other areas, so that the whole image display area of the tiled display device seen by the viewer basically maintains consistent brightness.
Referring to fig. 2b, in this embodiment, the moving direction of the tiled display apparatus is parallel to the long side of the sub-display unit 10, which is referred to as transverse translation, at different times t0, t1, t2, t0 < t1 < t2, the content of the image displayed by each sub-display unit 10 is different from that of the image of the previous frame, for example, when a triangle pattern is displayed, for example, at t0, the current display frame shows the complete left half of the triangle, but a part of the width at the rightmost side of the triangle is not displayed; during the fast rightward movement of the tiled display apparatus, the image displayed on each sub-display unit 10 by the triangle shifts to the left, that is, the undisplayed width on the left side of the triangle gradually increases, and the undisplayed width on the right side of the triangle gradually decreases, for example, at t1, the current display frame shows the middle part of the triangle, and a part of the widths on the left side and the right side of the triangle are not completely displayed, at this time, the undisplayed width on the left side of the triangle is increased compared with t0, and the undisplayed width on the right side of the triangle is decreased compared with t 0; the tiled display device continues to move rapidly to the right, and at t2, the current display frame shows the complete right half of the triangle, but the width not shown on the left side of the triangle reaches the maximum; when the tiled display device reversely returns, the compensation principle is similar, and in other embodiments, the tiled display device can also quickly and reversely return by using the non-display time period during the picture switching, so that the tiled display device cannot be observed by human eyes and the display effect is not influenced. Here, the positions of the tiled display devices corresponding to the times t0 and t2 are extreme positions of the leftmost side and the rightmost side, respectively, the overlapping width of the boundary compensation region formed by the lateral reciprocating movement of the middle first compensation region C1 is D1, the overlapping width of the boundary compensation region formed by the lateral reciprocating movement of the two side second compensation regions C2 is D2, the interval between t0 and t2 is very short, a complete triangle formed by overlapping a plurality of incomplete pictures can be observed by human eyes, and the picture width observed by the human eyes is the overlapping width of the display surface width and the unidirectional movement displacement of the tiled display device.
In the display device in which the sub-display units 10 are linearly arranged, the most significant influence on the brightness of the display screen is the boundary/splice joint perpendicular to the moving direction of the sub-display units 10 on each sub-display unit 10, and the shapes and widths of the compensation regions C1 and C2 of the first and second brightness compensation units 21 and 22 are respectively matched with the shapes and widths of the splice joint and the boundary between the sub-display units 10, that is, the widths of the compensation regions C1 and C2 of each brightness compensation unit are at least greater than or equal to the widths of the adjacent first and second non-display regions B1 and B2, and the widths are usually in units of the widths of the sub-pixels.
As shown in fig. 2B, the sub-display units 10 of this embodiment are spliced in the length (long side) direction, the moving direction of the sub-display unit 10 is parallel to the length direction, the compensation areas of the first brightness compensation unit 21 and the second brightness compensation unit 22 are both strip-shaped areas extending along the width direction of the sub-display unit 10, the displacement length of the sub-display unit 10 moving along the same direction (i.e. one-way) is not less than the width of a single splicing seam (i.e. the width of the first non-display area B1), so that it can be ensured that the splicing seam can perform brightness compensation better, the picture width that can be observed by human eyes of the spliced display device is the sum of the physical length of the spliced display device and the maximum one-way displacement of the spliced display device, and the height of the image display area is the display width of the single sub-display unit 10. During the movement of the display device, the images displayed in the sub-display units 10 are switched in real time, so that the currently displayed image and the image of the previous frame with persistence of vision can form a display image with continuous and natural transition boundaries.
As shown in fig. 2c, the present invention further provides a display method of the above tiled display device, including:
s01, moving the spliced display device back and forth along a preset path;
s02, switching the display frames of the sub-display units 10 in real time, and compensating the brightness of the display area corresponding to the joint seam between every two adjacent sub-display units 10 during the movement of each sub-display unit 10, and compensating the brightness of the display area corresponding to the boundary on the sub-display unit 10 intersecting the movement direction thereof, wherein the displacement length of the sub-display unit 10 moving along the same direction is not less than the width of a single joint seam. Particularly, when the first compensation region C1 of the sub display unit 10 covers a dark area screen formed by moving the first non-display region B1 between two adjacent sub display units 10, the luminance enhancement of the first compensation region C1 is controlled.
In the process of moving the sub-display units 10, the picture displayed by each sub-display unit 10 changes, so that the frame picture currently displayed by the display unit and the previous frame picture are combined into a new display picture, the tiled display device is moved continuously, the display area of the new display picture observed by human eyes is the combined area of the front and rear multi-frame pictures which cannot be perceived by human eyes, the image switching speed of each sub-display unit 10 is not less than 1/24 seconds per frame, and the frame picture which is kept in the persistence of vision and the current frame picture are perfectly combined.
Example 2
As shown in fig. 3a and 3b, unlike embodiment 1, the moving direction of the sub display unit 10 of the present embodiment is parallel to the short side of the sub display unit 10.
In this embodiment, the sub-display units 10 are spliced in the width (short side) direction, and the moving direction of the spliced display device is parallel to the width direction, which is referred to as longitudinal translation here, the compensation regions C1 and C2 of the first brightness compensation unit 21 and the second brightness compensation unit 22 are both strip-shaped regions extending along the length direction of the sub-display unit 10, the displacement length of the spliced display device moving along the same direction is not less than the width of a single splicing seam, so that the splicing seam can be ensured to perform brightness compensation better, the width of the whole image display region of the spliced display device is the display width of the sub-single display unit 10, and the picture height that can be observed by human eyes of the spliced display device is the sum of the physical width of the spliced display device and the maximum unidirectional displacement of the spliced display device.
Still taking the example of displaying a triangle pattern, at t0, the current display frame shows the entire upper half of the triangle, but a portion of the width at the lowermost end of the triangle is not shown; during the downward fast movement of the tiled display device, the image displayed on each sub-display unit 10 by the triangle shifts upward, that is, the undisplayed height at the upper end of the triangle gradually increases, and the undisplayed height at the lower end of the triangle gradually decreases, for example, at t1, the current display frame displays the middle part of the triangle, and a part of the heights at the upper end and the lower end of the triangle are not completely displayed, at this time, the undisplayed height at the upper end of the triangle is increased compared with t0, and the undisplayed height at the lower end of the triangle is decreased compared with t 0; the tiled display device continues to move rapidly downward, at t2, the current display frame shows the full lower half of the triangle, but the undisplayed height at the upper end of the triangle is maximized. Here, the positions of the tiled display device corresponding to the times t0 and t2 are the extreme positions of the uppermost end and the lowermost end, respectively, the stacking height of the boundary compensation region formed by the longitudinal reciprocating movement of the middle first compensation region C1 is D1 ', the stacking height of the boundary compensation region formed by the longitudinal reciprocating movement of the two end second compensation regions C2 is D2', and the intervals between t0 and t2 are very short, so that a complete triangle formed by stacking a plurality of incomplete pictures can be observed by human eyes, and the picture height observed by human eyes is the stacking height of the display surface of the tiled display device and the unidirectional movement displacement.
Example 3
In addition, the moving direction of the tiled display device may also form an acute angle with the long side or the short side of the sub-display unit 10, in this case, the luminance compensation area of the first luminance compensation unit 21 may be unchanged, while the luminance compensation area of the second luminance compensation unit 22 needs to compensate the boundary intersecting the moving direction of the sub-display unit 10 (i.e. the boundary in the length direction and the boundary in the width direction of the sub-display unit 10) at the same time, and the compensation principle will be described below with reference to the drawings.
As shown in fig. 4a, the tiled display device of this embodiment still has a first compensation region C1 adjacent to/parallel to the first non-display region B1, and unlike embodiments 1 and 2, the second non-display region B2 requiring luminance compensation is all the frame regions of the tiled display device, the second compensation region C2 includes a first sub-compensation region C21 parallel to the long side of the sub-display unit 10 and a second sub-compensation region C22 parallel to the short side of the sub-display unit 10, the first compensation region C1 is preferably adjacent to the first non-display region B1, two sides of the first non-display region B1 are respectively provided with a first compensation region C1, and the first sub-compensation region C21 and the second sub-compensation region C22 are preferably adjacent to the corresponding frame of the sub-display unit 10. During the display process, the first compensation area C1 compensates the first non-display area B1, and the first sub compensation area C21 and the second sub compensation area C22 compensate the bezel area of the sub-display unit 10.
As shown in fig. 4B, taking the linear motion of the tiled display device towards the upper right and lower left as an example, during the time period t0-t2, the tiled display device is translated towards the upper right, during which the luminance of the first compensation region C1 beside the first non-display region B1 is greater than that of the other regions of the sub-display region a, so as to compensate the luminance of the adjacent first non-display region B1 during the movement of the tiled display device, and the first sub-compensation region C21 and the second sub-compensation region C22 inside the second non-display region B2 compensate the luminance of the long-side and short-side regions of the second non-display region B2 respectively. More preferably, during the translation process of the tiled display device to the upper right, at time t1, the first sub-compensation region C21 located at the left side of the first non-display region B1 sweeps a dark region formed by the first non-display region B1, the first sub-compensation region C21 located at the upper end sweeps a dark region formed by a long-side frame at the top, and the second sub-compensation region C22 located at the right end sweeps a dark region formed by a short-side frame at the right end, so as to compensate for the corresponding dark regions, and further, the corresponding dark regions cannot be observed by human eyes through the persistence of vision.
The display device is formed by splicing a plurality of sub-display units, the sub-display units rapidly reciprocate along a preset path parallel to the display surface direction of the display device, and the brightness of the areas corresponding to the splicing seams in the display picture is consistent with that of other areas by performing brightness compensation on the areas corresponding to the splicing seams, so that dark zone areas on the picture caused by the movement of the splicing seam areas can be eliminated; meanwhile, the brightness compensation is carried out on the boundary on the sub-display unit, so that a dark band area on the picture caused by the movement of the black edge of the frame can be further eliminated, and the picture continuity of the splicing type display device 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.
