Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As technology advances, the dot pitch of pixels becomes smaller and smaller. High resolution, pixel pitch of 1.0 mm or less, tiled screens have been used in the commercial fields of stage, outdoor large screen displays, and the like. Common LED display screens are formed by splicing a plurality of display units. As the pixel pitch decreases, the requirement for a seam between display units increases. In the traditional technology, the display units with large dot pitch are often adopted for splicing, the requirement on splicing is not high, and the defects are not easy to feel when the display picture is subjectively seen. However, as the pixel pitch is smaller, the demand for the joint between the display units is higher, and if the joint is too large, the screen is broken, and if the joint is too small, the screen is misaligned. Therefore, in a high-resolution and small-pitch display device, it is necessary to adjust the joint between two display units so as to ensure the quality of the display screen.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present disclosure. The display device 100 includes a first display unit 1 and a second display unit 2, and the first display unit 1 is disposed adjacent to the second display unit 2. It can be understood that when the two display units are spliced, the two display units are inevitably connected to each other to generate a gap and a gap due to a manufacturing error or an assembly error. Referring to fig. 2, fig. 2 is a schematic diagram of a first display unit and a second display unit in an embodiment of the present application. The first display unit 1 and the second display unit 2 are arranged along a first direction X in which a gap exists between the first display unit 1 and the second display unit 2; the second direction Y is perpendicular to the first direction X, the third direction Z is perpendicular to both the first direction X and the second direction Y, and a break exists between the first display unit 1 and the second display unit 2 in the second direction Y and the third direction Z, and the break can be understood as a misalignment between the first display unit 1 and the second display unit 2. That is, in the second direction Y, the edges of the first display unit 1 and the second display unit 2 are not flush; in the third direction Z, the display surface of the first display unit 1 is not flush with the display surface of the second display unit 2. The gap in the first direction X, the offset in the second direction Y and the third direction Z all need to fall within preset ranges.
Referring to fig. 3 and 4, fig. 3 is a schematic structural view of the display device in fig. 1 from another angle, and fig. 4 is a schematic cross-sectional view of a position adjustment member, a connecting rod, and a first display unit according to an embodiment of the present disclosure.

The first display unit 1 is provided with a first connection hole 1a, the connection rod 4 comprises a first end portion 41 and a second end portion 42 which are oppositely arranged, the first end portion 41 is arranged through the first connection hole 1a, and the second end portion 42 is connected with the second display unit 2. The position adjusting member 5 is disposed between the first end portion 41 and the first display unit 1, the position adjusting member 5 abuts against the first end portion 41, the position adjusting member 5 abuts against the first display unit 1, and the position adjusting member 5 is rotatable about the connecting rod 4 so that the position of the first display unit 1 can be changed relative to the second display unit 2.
It can be understood that the first end portion 41 of the connecting rod 4 has a gap with the first connection hole 1a, and the position adjuster 5 is disposed between the connecting rod 4 and the first display unit 1. The connecting rod 4 is connected with the second display unit 2, and the second display unit 2 and the connecting rod 4 can be regarded as a 'fixed end'. When the position adjusting member 5 moves around the connecting rod 4, the position of the first display unit 1 in the second direction Y and the third direction Z can be changed, that is, the first display unit 1 rotates around the connecting rod 4 in a small range, so as to adjust the difference between the first display unit 1 and the second display unit 2.
Illustratively, the position adjusting member 5 may be a ball disposed in the first connection hole 1a and received between the first display unit 1 and the connection rod 4. It will be appreciated that the ball slides in the gap between the first display unit 1 and the connecting rod 4, and the position of the ball in the gap is different, so that the displacement of the first display unit 1 in the second direction Y and the third direction Z is different, and the position of the first display unit 1 relative to the second display unit 2 is different. The ball is movable in a plane formed by the second direction Y and the third direction Z to cause a radial displacement of the first display unit 1 along the axis of the connecting rod 4.
