China's Big Screen Billboards

These “Big Screen Billboards” in China are astonishing. OK, the scale of digital display surfaces is truly enormous. However, they also employ perception-tricks to achieve the persuasive effect that objects are leaving the screen.

Look closely. They often start with clearly defined border projected around the subject image. It is a shock when the lion (for example) reaches out across that false-border into the "real world." Initially unilluminated areas of the billboard allow the object being displayed inside the false-border to escape it and expand onto the full extent of the billboard screen area. Thus, they appear to be in the real world.

Great technology and great display psychology! Great fun.
