Description
Technical Field
The invention relates to the technical field of screen splicing, in particular to a spliced LED display screen and an installation method.
Background
Application number: CN202110785009.8 discloses a monitor screen splicing system and a splicing method. One embodiment of the system comprises: user control end, screen concatenation equipment, decoder, screen projection source, wherein: the screen projection source is configured to send the coded video set included in the screen projection source to the screen splicing device and the user control end; the user control end is configured to determine screen splicing scheme information according to the received coded video set; the user control end is configured to send the screen splicing scheme information to the screen splicing equipment; the screen splicing device is configured to send the screen splicing scheme information and the coded video set to the decoder; the decoder is configured to perform monitor screen splicing according to the received screen splicing scheme information and the coded video set to obtain a screen splicing result. The embodiment can reduce network fault points and improve decoding efficiency. In addition, the display screen may accommodate higher and higher video resolutions.
Application number: CN200610157801.4 discloses a multi-screen display splice controller, which aims to improve the anti-interference capability and stability of the controller, so that the image content is not damaged and no image noise point is added. The multi-screen display splicing controller comprises a high-definition video signal source and a decoder, wherein signals output by the decoder are transmitted to a display split-screen image data generating circuit; the display split-screen image data generating circuit includes: the display sub-screen comprises a phase-locked loop, a synchronous signal generator, a buffer controller, a buffer and a display sub-screen internal circuit. Compared with the prior art, the main circuit is based on the design of the programmable logic device FPGA and the embedded system, has the advantages of high anti-interference capability and high stability in digital circuit processing, does not damage the image content by taking a single pixel as a processing unit, does not add any image noise point, completely meets the high-definition display requirement, can be separated from a computer to independently run, can work normally when being started, and has high speed.
At present, since the edge of each piece of LED screen is provided with a frame to protect a screen substrate main body, a distance exists between the spliced screen and the screen, and when the content is displayed, a picture video and characters can be split, a split sense is generated, so that the viewing sense is poor, and the existing spliced screen solution has two types:
the first is a monitor group, and the liquid crystal monitors are stacked to form a large monitoring wall, which is mainly applied to security monitoring projects. Since the monitor has a frame, for example, a single 21 inch LCD screen frame typically has 6-10mm and the splice seam has 12-22mm. The 46-inch liquid crystal monitor group has the greatest advantage of replacing the early heavy CRT television wall, and the display effect is greatly improved. Because the single monitors are stacked, the joint is huge, and an integral logic screen is difficult to form, and the essential difference exists between the single monitors and the true high-resolution digital display spliced wall
The other is to splice the ultra-narrow side liquid crystal screen, the early-stage splice is 22mm, and the competition advantage is not great compared with the monitor group. The ultra-narrow side liquid crystal spliced screen with the seam of 7.3mm is provided by later-stage manufacturers to become a mark product entering a large-screen spliced display product series, and the narrower seam is more conducive to forming a large screen with ultra-high resolution by a single spliced unit, so that the functions of whole-screen display, window display, picture roaming, movement and the like are realized.
In summary, due to the limitation of the prior art, the problem of the splicing gap cannot be avoided basically in the common screen, and unless a projector, an edge fusion device and a splicer are adopted or a new processing module, a new controller and the like are developed, the real seamless splicing can be realized theoretically, as shown in application numbers CN200610157801.4 and CN202110785009.8, but the cost of the methods is high, so that the spliced LED display screen and the installation method are provided.
