LED ice screens have appeared many times on the stage of the 9th Beijing International Film Festival

On the evening of April 13, 2019, the 9th Beijing International Film Festival was grandly opened at the National China Film Digital Production Base in Huairou, Beijing. Xiang Shengju.

The star-studded stage is naturally indispensable with the help of LED displays. It is reported that this event was designed by Mr. Han Lixun, the chief designer of the Beijing Olympic Games. The main stage is designed with a 270-degree surround screen theater.

A total of seven matt ice screens are used on the two floors in front of the main screen, and real movie projectors are placed in the auditorium, which gives filmmakers a sense of belonging home and makes the main stage performance area more immersive sensory experience.

Many friends here should have noticed that the familiar ” LED Ice Screen” appeared again on the stage of this Beijing International Film Festival. Since the “Beijing Eight Minutes” at the closing ceremony of the Pyeongchang Winter Olympics, the ice screen has become popular.

After one hand, the popularity of the ice screen in the field of stage art seems to have been on a continuous heating trend, and it has become a “frequent visitor” of stage art. What charm is the ice screen uniquely favored by stage designers?

Breaking the limitations of conventional screens, LED ice screens present surreal stage beauty

The ice screen is still essentially a transparent LED display, which can be regarded as the “pure desire ceiling” in the transparent display. As a high-end transparent LED display, what is the realization principle of the transparent LED display ice screen? It looks like a high-transparency louver from the outside. Its design greatly reduces the obstruction of the line of sight of structural components, and the transmission rate can reach more than 90%, which maximizes the perspective effect, which is clear at present.

The display device with the highest resolution and the best perspective effect. The transparent LED display has a novel and unique display effect. When the audience is watching from an ideal distance, the picture is like floating on the glass, and it does not affect the original lighting function of the glass.

The transparent LED ice screens does not cause visual obstacles to the stage space at all. When the stage needs it, it can be colorful, and when it is not needed, it can be invisible. This feature of the ice screen enables it to perfectly restore the creative design of the stage. The LED transparent ice screen uses the common screen display skills and the transparent characteristics of the screen body to form a three-dimensional realistic and virtual aspirational space. Multi-screen co-display makes the image of the space move and the stage function enhances the sense of hierarchy and movement.

It will greatly improve the performance of the program, make the LED screen seamless with the real scene, and compare with the two-dimensional scene effect of the traditional LED display. The three-dimensional sense and reality of the three-dimensional space appear, the visual effect is shocking, and the audience continues to be visually presented. Bringing new ideas together allows the audience to empathize, so that the stage conforms to the traditional aesthetic concept, and it is very real from the near and far view, and it has a perfect stage effect.

To seize the market, screen companies must first lay out patents

Up to now, there are 223 related patent applications filed in China, mainly related to improving the transparency of the transparent screen (such as reducing the width of the light bar, changing the installation method of the light source), and enhancing the stability of the transparent screen (such as improving the welding process, Speed ​​up the heat dissipation of the screen, improve the waterproof performance of the display), simplify the splicing and installation of transparent screens, provide flexible transparent screens, and expand the application methods of transparent screens. In terms of application types, the largest number of patent applications are utility model patent applications.

This shows that the LED industry has a relatively fast technology update, so companies are more inclined to submit applications for utility model patents that have been authorized quickly. It is worth noting that in addition to LED display companies, there are also many cross-field companies that are also committed to the research and development of transparent displays. Google filed a patent application in March 2016. The application relates to a miniature LED transparent screen, which can be set on wearable devices such as glasses. The micro LED screen can also switch between transparent mode and opaque mode to present AR or VR effects.

As the saying goes, “People have no long-term worries, there must be immediate worries.” This sentence is also applicable to enterprises. At present, the application of LED transparent screens has not yet been fully popularized. The number of display companies engaged in transparent screen production in the industry is currently relatively small, and companies with transparent screen related patents are even rarer.

The market prospects of LED transparent screens are very impressive. Some organizations predict that the market output value of transparent displays will be about 87.2 billion U.S. dollars by 2025, and more and more companies will participate in it in the future.

Therefore, for related companies in this field, they must take precautions, combine their own strengths, find a suitable entry point from the trend of future technological development, invest in research and development in advance, and protect the intellectual property rights of the research and development results as soon as possible to achieve “product Untouched, patents go first” in order to win the first opportunity in the fierce competition.

The wonderful appearance of “ice screen” in the field of stage art and even more other fields has allowed more people in the industry to see the wonderful display of the unique advantages of LED transparent ice screens and the broad market prospects. However, due to many in the industry Enterprises have not done enough research and development on LED transparent ice screens, so this part of the market has not developed as expected.

However, this has also inspired screen companies. If they want to compete for the tens of billions of transparent display market, they must begin to pay attention to the scientific and technological innovation and research and development of transparent displays.

Although the LED transparent ice screen display technology has not attracted everyone’s attention at this stage, it is believed that in the near future, when the LED transparent display technology has been further improved, the LED transparent ice screen will definitely be able to pass the test, in a broader field Show off your style.
