What are the advantages and disadvantages of LED display screen entering the film market?

LED display screen is self luminous, which is different from the traditional projector. Therefore, it is questioned by veteran filmmakers that it is only a "large TV screen". However, due to the short service life and energy consumption of the mainstream metal halogen bulbs for commercial projection, manufacturers also choose new light sources to challenge the mainstream digital projection technology. LED display screen is one of them.

From the perspective of picture update rate and resolution, LED display screen can improve the audio-visual feeling and achieve 3D like functions than traditional digital projection equipment, bringing different business opportunities for 3D naked eye technology. In terms of screen content, the peak brightness is as high as 146fl, ten times higher than 14fl of standard movie projector, which can better reduce the dizziness caused by low brightness.

Now, the global film market has reached US $40 billion. However, this market is increasingly eroded by home entertainment systems and services, such as giant TV screens, on-demand video and Dolby panoramic sound. For this market, the emergence of LED film screen is a remarkable innovation.

However, LED display technology still needs to be broken through, including heat dissipation, high power consumption, cross of bad points and other problems, which are challenges affecting the popularity of LED display screens. Therefore, in order to meet the needs of cinema maintenance and replacement, the display screen must also have the function of instant plug-in. In addition, the high technology and high cost of LED display screen is also a major obstacle to popularization.
