[embodiment]

Below in conjunction with specific embodiment and Figure of description purpose of the present invention, technical scheme and advantage are described in detail.

The invention provides a kind of method of display device splicing, as shown in Figure 2, mainly may further comprise the steps:

The shear factor of step S101, calculating splicing back display apparatus:

Be that the spliced display device screen of hypothesis is continuous in the present invention, and in fact piece is arranged between the screen, therefore need cut off image Central Plains should be in the part of edge joint position demonstration.The width of image when shear factor x representative image is displayed on the piece position also promptly needs the width that cuts off.

Calculate total length and piece width that shear factor x at first measures display device splicing back screen, and detect the display resolution of each display device, and calculate the shear factor x of splicing back display device with this.

If screen is vertically splicing, then at first measures the overall height and the piece width of display device splicing back screen, and detect the height of the display resolution of each display device;

Calculate shear factor x according to following formula then:

x＝(h/(m₁h+h+m₂h))*H

Wherein, h represents the piece width, and H represents the overall height of display device splicing back screen, m₁H and m₂H represents the height of tiled display device resolution respectively.

If screen is the level splicing, then measures the overall width and the piece width of display device splicing back screen, and detect the width of the display resolution of each display device;

Calculate shear factor x according to following formula then:

x＝(h/m₁w+h+m₂w)＊W

Wherein, h represents the piece width, and W represents the overall width of display device splicing back screen, m₁W and m₂W represents the width of tiled display device resolution respectively.

Step S102, in the zone of each one times of described shear factor of the image closing line both sides parallel with piece, shear the zone of one times of described shear factor along centerline direction:

As shown in Figure 3, two display devices with vertical splicing are that example describes.As figure, be total in the zone of 2x at each one times of described shear factor of image closing line upper and lower sides, belong to the zone that can be sheared.The width of shearing is the length of one times of shear factor 1x, and the position of shearing is so long as get final product in the zone of above-mentioned 2x.The display device that splices on the horizontal direction in like manner.

Step S103, the image after above-mentioned both sides are sheared move the zone that is sheared with covering to described image closing line:

After the shearing, past image closing line place moves with the image of image closing line both sides, is sheared blank zone, back with covering and forms new image.How many images are each side cut off and just move distance how long to the image closing line, can fill up blank zone and can not overlap just like this.It should be noted that because the following image of image closing line is a display device by the below to show that the image after upside is sheared can not move to below the image closing line, otherwise the image that the display device of downside shows will be the image of " disconnected cutting ".In like manner, the image after downside is sheared can not move to more than the image closing line.

Because image can move to the image closing line after the image cut, will inevitably cause the image at image two ends to leave some space, as making full use of the viewing area of display device, can be when the construction drawing image source, with double the in advance length of shear factor of the image in the image source.

Step S104, the image after described move outputed in the display device of splicing and shows:

The present invention handles the image in the image source, cutting off image should be in the part of edge joint position demonstration, the effect that its image shows as shown in Figure 4, shown image is continuous for the spliced display device screen of spectators, just the image at edge joint position does not show, but its whole vision is continuous, has visual experience preferably.
