[0002] Traditional outdoor large-scale advertisements mostly adopt the method of fixing the advertisement screen on the wall, but the disadvantage is that the advertisement capacity is small and the content is single; in order to increase the advertisement capacity, the advertisement is wrapped on the roller, and the reciprocating cycle is driven by the forward and reverse motor , so that each advertisement picture has a chance to be displayed, so as to achieve the purpose of reducing the singleness and increasing the amount of advertisements; its shortcoming is that the most extreme advertisement is displayed last in the previous round, and immediately after the reversal, it will be the last in the next round First display, so that the time interval between two display of the same picture is too short, compared with other position ads, its effect will be affected
On the other hand, this form of advertisement may have an instinctive resistance to the audience because it is exposed when changing the screen.
There are also some popular forms of outdoor advertising in recent years, such as outdoor giant TV screens, outdoor LED advertisements, etc. These forms of advertising have a large amount of information and good dynamic performance, but they have defects such as high cost and short life.
