We know that Samsung is a well-deserved leader in the field of LED theaters. On February 4, 2018, Samsung and Wanda Group held China's first Samsung small-pitch LED display theater opening celebration at the Wanda Plaza store in Wujiaochang, Shanghai. All of a sudden, discussions such as 'movie projector farewell to historyBut is this really the case? Comparison of the effects of traditional projectors and LED movie screens According to the People’s Daily report, as of March 2017, the total number of screens in my country reached 44,489, surpassing the entire North American region and becoming the world’s largest movie market in terms of market capacity. my country is the first in the world to fully realize digital projection, of which 38,377 3D screens, accounting for 86.26% of the total number of screens, the total number of giant screens (IMAX and Chinese giant screens) has reached 616, its scale is the world's largest. In the cinema line, the small-pitch LED display has an absolute advantage, conforms to the DCI-P3 color gamut standard, and has a brightness of 146fl, which is 10 times that of the traditional digital cinema. Coupled with active light emission, it naturally has high anti-light interference characteristics, which can bring more Good movie viewing experience. However, 4K projectors can only achieve high-definition picture quality in the center area of u200bu200bthe screen, and there is usually a problem of defocusing at the edges. However, at present, the fare of the LED theater is almost twice that of the IMAX hall, which is a flaw. The low brightness value is also one of the reasons that the projection has been criticized. Too low brightness can easily cause dizziness, dizziness, and pain in the eyes of users watching for a long time. The LED display factory can ensure that the LED display achieves different brightness by selecting the appropriate lamp beads, driver IC and controller, and designing a reasonable circuit. At the same time, the LED display is actively luminous, and the surface mask adopts a diffuse reflection design to ensure that the screen is exposed evenly and the display effect is consistent. The high cost and high technology configuration are currently an important obstacle to the entry of LED displays into the cinema market. This is a problem that LED display companies must consider; for the audience, the most intolerable thing for viewing LED displays is: black screen or no display. In the signal area, most of the cases are due to the failure of the switching power supply. Compared with projectors, the failure rate of LED displays is higher than that of projectors due to the size of the system. Therefore, if you want to really push LED displays to the cinema market, the improvement of reliability is an important system project in the industry. It must be mentioned that the cinema is a crowd-intensive place, and there is a certain burning risk for the LED display to heat up. Therefore, the selection of flame-retardant or non-combustible materials is the basic requirement for the LED display to enter the cinema line. Due to the limited space of the theater, the impact of thermal radiation and electromagnetic radiation on the human body must be fully considered. From a long-term perspective, it is not impossible for the small-pitch LED display to replace the traditional projection. This vision will also lead the display device to a better direction.
