Wherein the splicing area is rectangular.
As a preferable example of the present embodiment, the width and height of each single screen are the same. When the individual screens are spliced with each other by their widths, it is regarded as a lateral splice, where the width of the spliced area=the width of the individual screens, the number of individual screens, and the height=the width of the individual screens. The display screen after transverse splicing is shown in figure 2. When the individual screens are spliced with each other by their height, they are regarded as vertical splicing, where the width of the splicing area=the width of the individual screen, and the height=the width of the individual screen. The vertically spliced display screen is shown in fig. 3.
It should be noted that, in order to improve the display effect, the display screen spliced by each single screen is a 55 inch high definition display screen.
