The advantage of small space LED screen in the display market is a well-known concept: brightness, specific illumination and color. In these three dimensions, most LED displays can surpass the “best projectors”. Because, after all, projectors rely on reflective imaging, which can not prevent the interference of ambient light. Therefore, even if the film projection system with several million yuan wants to get a good experience, it still needs the form of “small black house”.
Of course, the small black house form of cinema also has its very good “reaction”. For example, it doesn’t need to be meaningless for a couple to be close to each other, for example, to be frightened or have mixed feelings, because at least the people around them can’t see it（ However, dapingjun should also kindly remind the audience that there is night vision monitoring in the cinema projection hall From this point of view, if the large LED screen can be used to turn on the lights, the “mystery” of the cinema will be lost, and it is unknown whether part of the audience will be lost.
However, before the small spacing LED screens enter the cinema, people are more concerned about the technical feasibility than the change of operational value
First, whether the visual warmth of small space LED can be successfully dealt with. In practice, video display on LED screen is not a new function – outdoor advertising, indoor digital Notice, which one is not a video based scene? The problem is that the film needs a kind of “beautiful” experience, not the “simple communication” of traditional advertising screen. Moreover, although the projection Hall of the digital cinema is large, compared with the advertising screen, the viewing interval is much closer, and the continuous viewing time is more than tens of times – which puts forward a high request for the warmth of the picture quality.
Second, as far as display technology is concerned, resolution is a fundamental factor. This is also the reason why the LED display industry has not thought of seizing the digital film screening market in decades of history. Now, due to the small space LED screen and the mature high-resolution LED display system, Samsung is excited to compete in the digital projector market. The maturity of small spacing LED technology can be described as follows: seven or eight years ago, it was also regarded as a 2.0 spacing product of “off-site” technology, and once became a market Chinese cabbage with the innovation of many domestic manufacturers; P1.5, P1.2, P1.0 and p0.8 products all entered the large screen display market.
However, pixel centered resolution is not a simple “game of quantity”, but an important concept of quality. Why do more than 95% of the digital cinemas in the world use DLP technology projectors? Dapingjun must point out that the DMD light valve chip of DLP projection technology center has more than 90% opening rate, and the “grainless feeling” of the finished picture is the key factor. In this regard, the traditional small spacing LED screen may fail.
