Movie theaters have a history of more than 120 years. With the development of the times and the continuous improvement of technology, people's movie viewing experience is getting better and better. However, most movie theaters today still use early projectors. It stands to reason that, according to the current level of technology, it can be replaced by a full-color LED display, so why do movie theaters still use projectors and why not full-color LED displays?

  The first is the price does not allow. Since so many LED lamp beads need to be installed in a limited space, the process requirements are very high, and there are problems such as heat dissipation and circuit to be solved, which require a relatively large cost; and the current yield rate is low, which is also caused by At present, an important factor for the high price of small-pitch full-color LED display products. Even a standard display screen costs several million yuan. This price can build a standard movie theater, so this is the main reason for limiting the popularity of full-color LED displays.

  The second is maintenance difficulties. Although the life of LED lamp beads can reach more than 100,000 hours, due to its extremely high density, it is difficult to dissipate heat in a limited space, and local failures are prone to occur. Faced with such a behemoth, maintenance and repair alone is not a simple matter, and it requires a lot of manpower and material resources. In the event of some major failure, the full-color LED display cannot be used and needs to be replaced.

  Finally there is the installation problem. Not long ago, I saw a local tyrant bought a 100-inch TV, which could not get on the elevator at all, so he asked someone to use a crane to lift it up. The installation cost alone cost 20,000 yuan. It is conceivable that the cost of installing the screen in the cinema is even more expensive. It may be possible to use LCD splicing technology, but these technologies are also very expensive and labor-intensive.

  In addition to the above main reasons, there are also factors such as resolution, refresh rate, and visual comfort that restrict the current movie theaters from being unable to install full-color LED displays. However, with the future technological progress and production capacity growth, as well as the further improvement of the yield rate, I believe that the small-pitch full-color LED display will gradually enter the cinema and meet you.
