Abstract

The invention discloses a seamless video display spliced wall. The seamless video display spliced wall is formed by splicing a plurality of displays; and a plurality of light emitting diodes (LEDs), the brightness and the color of which are matched with the display image conditions of the adjacent displays, are arranged in the spliced seams of the displays. The LEDs are connected with a main control computer through control wires. The main control computer sends corresponding data to each LED according to the actual image displayed by the video display spliced wall, and independently adjusts the LEDs so that the LEDs display the brightness and the color matched with the images displayed by the adjacent displays. Therefore, the purpose of eliminating and reducing the spliced seams between the displays is fulfilled. Or, each LED can be connected with an independent optical detector. The optical detector detects the image information of the adjacent display and transmits the image information to the LED connected with the optical detector, and the LED displays the brightness and the color matched with the image displayed by the adjacent display. The original spliced seams of the video display spliced wall are greatly faded, and an integral effect of seamless splicing is achieved.

Description

Each display can be a kind of of all display techniques, includes but not limited to LCD and plasma display.LCD LCD and plasma display PDP have a physics frame, and all there is splicing slit in various degree in all video display splicing walls at present, can't reach perfect visual effect.
A kind of more detailed technical scheme of the present invention:
Said LED is connected with the master control computer through independent control line.Said master control computer sends to corresponding data on each LED according to the real image that video display splicing wall shows, regulates LED and makes LED demonstrate brightness and the color that matees with the proximity displays display image.
Each said LED further comprises a plurality of LED that Width is arranged along video display splicing wall splicing seams slot footpath again.Laterally different according to erecting of splicing seams itself; Be preferably; Two LED about each said LED further comprises again or up and down; Said master control computer sends to corresponding data on each LED according to the real image that video display splicing wall shows, regulates LED and makes LED demonstrate brightness and the color that matees with the proximity displays display image.
Comprise the light spacer assembly between each said LED, make the light of adjacent LED not crosstalk.
Each said LED top comprises a slice diffusion sheet; Optical property through the design diffusion sheet; Make the luminous of LED, not only showing approaching, and also approaching aspect the visual angle with its neighbour aspect color and the brightness with LCD display; The obvious originally slit that exists of desalination reaches seamless spliced whole structure greatly.
The more detailed technical scheme of another kind of the present invention:
Each said LED connects an independently photo-detector.Said photo-detector detects neighbour's display image information and sends the LED that is attached thereto to, and LED demonstrates brightness and the color with proximity displays display image coupling.
Each said LED further comprises a plurality of LED that Width is arranged along video display splicing wall splicing seams slot footpath again.Perpendicular laterally different according to splicing seams are preferably, two LED about each said LED further comprises again or up and down, and said each left side LED shows the information of left side neighbour's pixel, said each the right LED shows the information of the right neighborhood pixels.
Comprise the light spacer assembly between each said LED, make the light of adjacent LED not crosstalk.
Each said LED top comprises a slice diffusion sheet; Optical property through the design diffusion sheet; Make the luminous of LED, not only showing approaching, and also approaching aspect the visual angle with its neighbour aspect color and the brightness with LCD display; The obvious originally slit that exists of desalination reaches seamless spliced whole structure greatly.
Advantage of the present invention is: the present invention utilizes the light emitting array of LED, and LED is placed in the splicing slit, and the brightness and color of each LED changes with its proximity displays image pixel, and the obvious originally slit that exists of desalination reaches seamless spliced whole structure greatly.
