Problems solved by technology

[0003] However, as long as there is a physical seam in the display device, when the display device performs splicing display, it must process the seam. There can be a continuous display effect; due to the above-mentioned clipping of the display screen, some algorithms will need to perform special processing at the splicing point. Seam cutting and image splicing, although this processing method can improve the continuity of the displayed image, it cannot effectively avoid the loss of the image content that is cut at the edge of the display
In addition, on the premise of not performing cropping processing on the display edge seam, although the display mode of the spliced ​​image can be simplified, it will form an obvious image displacement effect at the display edge seam, resulting in obvious discontinuity in the displayed image
[0004] Therefore, in addition to increasing the difficulty of display content processing and the actual operation of the image enhancement algorithm when performing spliced ​​display on the existing display device, corresponding processing needs to be done each time the size of the spliced ​​edge seam changes. The content of the displayed image can have better continuity at the display edge seam, but it cannot avoid the loss of the cropped image content at the display edge seam

Embodiment 1

[0031] refer to figure 1 and Figure 2a The spliced ​​display device according to the embodiment of the present invention mainly includes at least two spliced ​​sub-display units 10 and a first brightness compensation unit 21. The spliced ​​display device has a sub-display area A corresponding to the display surface of each sub-display unit 10, In the first non-display area B1 corresponding to the seam between two adjacent sub-display units 10, the sub-display area A has a first compensation area C1 close to and parallel to the first non-display area B1. In this embodiment Preferably, the first compensation area C1 is in contact with the splicing seam, and the width of the first compensation area C1 is not smaller than the first non-display area B1. The compensation area C1 is used to cover the dark image formed by the movement of the first non-display area B1 during the movement of the connected display device. Wherein, the first brightness compensation unit 21 is used to c...

Embodiment 2

[0043] Figure 3a , 3b As shown, different from Embodiment 1, the moving direction of the sub-display unit 10 in this embodiment is parallel to the short side of the sub-display unit 10 .

[0044] 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 its width direction, which is referred to as vertical translation here. The first brightness compensation unit 21, the second brightness compensation unit 22 The respective compensation areas C1 and C2 are strip-shaped areas extending along the length direction of the sub-display unit 10, and the displacement length of the splicing display device moving in the same direction is not less than the width of a single splicing seam, so that the splicing can be guaranteed The slit can better perform brightness compensation. The width of the entire image display area of ​​the splicing display device is the display width of t...

Embodiment 3

[0047] In addition, the moving direction of the spliced ​​display device may form an acute angle with the long side or short side of the sub-display unit 10. At this time, the brightness compensation area of ​​the first brightness compensation unit 21 may remain unchanged, while the second brightness compensation The brightness compensation area of ​​the unit 22 needs to compensate the boundary intersecting the moving direction of the sub-display unit 10 (that is, the boundary in the length direction and the boundary in the width direction of the sub-display unit 10 ). The compensation principle will be described below with reference to the accompanying drawings.

[0048] Such as Figure 4a As shown, the mosaic display device of this embodiment still has the first compensation region C1 adjacent to / parallel to the first non-display region B1, and the difference from the above-mentioned embodiments 1 and 2 is that the second non-display region C1 that needs brightness compensati...

Abstract

The invention discloses a spliced display device and a display method thereof, the display device includes a sub-display area corresponding to the sub-display unit, a first non-display area corresponding to the splice seam and a first brightness compensation unit, wherein the sub-display area includes a first compensation area close to and arranged in parallel with the first non-display area, thewidth of the first compensation area is not smaller than the first non-display area, and the splice display device reciprocates along a predetermined path parallel to the display surface; The first compensation area is used for covering the dark area picture formed by the movement of the first non-display area during the movement of the mosaic display device, and the first brightness compensationunit is used for controlling the brightness enhancement of the first compensation area when the first compensation area covers the dark area picture formed by the first non-display area, and the second compensation unit is used for controlling the brightness enhancement of the first compensation area when the first compensation area covers the dark area picture formed by the first non-display area. The invention eliminates the dark band area on the picture caused by the movement of the splicing joint area by compensating the brightness of the area corresponding to the splicing joint in the display picture, and is helpful to realize the picture continuity of the splicing display device.

Description

technical field [0001] The present invention relates to the technical field of spliced ​​display, in particular to a spliced ​​display device and a display method thereof. Background technique [0002] In order to meet the needs of display panel splicing, the existing splicing technology focuses on reducing the frame of the display device, so as to minimize the splicing edge seam between the display devices, so that the spliced ​​display device can have a relatively good and continuous display. Effect. [0003] However, as long as there is a physical seam in the display device, when the display device performs splicing display, it must process the seam. There can be a continuous display effect; due to the above-mentioned clipping of the display screen, some algorithms will need to perform special processing at the splicing point. Seam cutting and image splicing, although the continuity of the displayed image can be improved in this processing method, but it cannot effectiv...
