Technical Field

[0001] The utility model relates to the technical field of liquid crystal screens, in particular to a picture compensation device for a liquid crystal splicing screen. Background Art

[0002] The LCD splicing screen can be used as a display alone or spliced ​​into a super large screen. According to different usage requirements, it can realize the function of a large screen that can be enlarged or reduced. At present, when the LCD splicing screen is in use, it is necessary to use a picture compensation device, that is, a video compensator. When the video signal is attenuated during long-distance transmission using a coaxial cable, the received video signal can be restored through this device, so that the attenuated image signal can be almost restored after being processed by the video compensator.

[0003] The existing picture compensation device is generally placed directly between multiple LCD screens when in use. It has no fixing effect and is easily dropped or shaken due to external factors during use. It is also very easy to be disconnected from the connecting wire, which will affect its normal use. Therefore, we introduce a new picture compensation device for LCD splicing screen. Utility Model Content
