Embodiment
Embodiment 1
As Figure 1-5, a kind of liquid crystal-spliced screen for supporting ultra high-definition long-distance transmissions, including liquid crystal display 1, liquid crystal display 1
At least more than one is provided with, is stitched together between screen and screen by splicing support, liquid crystal display 1 includes screen 2, frame 3, set
Put circuit board 4, video frequency compensator 5 and image processor 6 internally, video frequency compensator 5 and image processor 6 are and circuit board
4 connections, video frequency compensator 5 includes video input interface 7, video output interface 8, video signal compensating circuit 9 and Signal averaging
Device 10, video input interface 7, video signal compensating circuit 9, Signal averaging device 10, video output interface 8, image processor 6 according to
Secondary connection, video signal compensating circuit 9 is used to detect video input signals, and when dropout occurs for video input signals,
Thermal compensation signal is obtained, the compensation that Signal averaging device 10 is used to generate the vision signal of input and video signal compensating circuit 9 is believed
Number it is superimposed, video output interface 8 exports the vision signal that Signal averaging device 10 is treated to image processor 6, figure
As processor 6 feeds back to liquid crystal display 1 again, it is shown on liquid crystal display 1, the bottom both sides of video frequency compensator 5 are extended with stator 11, Gu
The bottom of stator 11 is provided with buckling piece 12, and liquid crystal display 1 is internally provided with mounting groove 13, mounting groove 13 and is provided with and buckling piece 12
The catching groove 14 of cooperation, video frequency compensator 5 is arranged on mounting groove 13 by the cooperation of buckling piece 12 and catching groove 14.
The stability of image is mainly obtained by synchronizing signal, and color is mainly reduced by colour burst signal, color
Synchronous frequency PAL-system is 4.43MHz, therefore video standard signal is after long-distance transmissions, synchronizing signal and colour burst signal
It will decay, the high frequency in vision signal can also decay, so that cause gradation of image grade to decline, definition reduction, coloured image
Become black white image, image level is obscured, resolution ratio reduction, picture signal is dim, so as to not reach the design requirement of system.
After picture signal after decay is compensated through video frequency compensator, picture signal is set to be reduced into video standard signal, can be after compensation
Black-and-white signal is reduced into colour signal, makes image level clearly demarcated, reaches the image effect before decay.
