Nowadays, the rise of video streaming platforms urges the film and television market to develop vigorously. Film producers pursue breakthroughs in shooting quality, speed and cost. The filmmaking technologies become innovative in response to the market demand, and so is the virtual production. The film production applied green screens as shooting background in the past; however, the virtual production adopts LED displays. For shooting, the advantages of LED displays provide real light effect and delicate color performance, bringing the best pictures to audiences. For filmmaking, LED displays can increase production efficiency and reduce total cost. Industry insider is really optimistic that LED displays will replace green screens in the near future.

Traditional green screens are replaced by LED displays

Despite many benefits of LED displays, there are still challenges of using LED displays as backdrops in virtual production, like color shift, Moiré, signal delay and so on. These challenges may be solved through post-production, but it may be costly and time consuming. The challenges can be overcome through the use of specific LED display modules.

There are two kinds of LED display modules, one is COB (Chip On Board) LED display and the other is SMD (Surface Mounted Devices) LED display. It is expected that COB LED displays are more suitable for the backdrop of virtual production than SMD LED displays in terms of “image quality” and “resistance in harsh conditions”. Please refer to the following:

• 1. Image quality: The high fill factor optical design of COB LED displays empowers display units turning from a point source to a surface source, so that the image performance is more uniform and without facula. Moreover, the coating technology of COB LED displays significantly enhances contrast, mitigates Moiré and reduces glare, greatly improving visual comfort. Furthermore, COB LED displays also decrease the situation of color shift; therefore, it is more flexible for filmmakers to film.
• 2. Resistance in harsh conditions: COB LED displays are highly stable and easy to maintain. Their features include anti-collision, compressive strength, moisture-proof, dust-protected, oil-proof, anti-oxidation, antistatic and so on, so that they can be applied in various film production environments.
