Douyin is a very popular short video APP. It has a very interesting feature, that is, three screens often appear in some videos. The so-called three screens mean that three different pictures are displayed on one screen at the same time. This form of picture allows the audience to see more different information at once, thus better attracting their attention.

In many cases, the three-screen display method of Douyin also has some specific meanings. For example, in music-related videos, many people use three screens to display lyrics, MVs, and their own dances. This kind of picture format can better demonstrate the perfect combination of music and dance, and attract more people to try dancing to the music.

In addition to these entertainment purposes, Douyin’s three-screen display method is also very common in some commercial fields. For example, in a product promotion video, the three-screen approach allows people to see multiple information such as the product's appearance, usage scenarios, and user feedback at once, allowing them to better understand the features and advantages of the product. Such usage can help companies better market their products and increase sales.
