LED ice screens have repeatedly shown their talents 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.

What are the technologies in the LED display lamp beads?

The application of LED display is very wide, and besides the control system, power supply and other accessories, the most important thing is still the LED lamp beads. This is like a computer without a display, even if the host is in a powerful way, it will not play any role. of. So today we will talk about LED lamp beads. At present, the luminous color and luminous efficiency of LED lamp beads are related to the materials and processes used to make LEDs. Different materials used to make LEDs can generate photons with different energies, thereby controlling the wavelength of the light emitted by the LED, that is, the spectrum or color. The currently known technologies mainly include the following: 1. Transparent substrate technology InGaAlP LEDs are usually prepared by epitaxially growing InGaAlP light-emitting areas and GaP window areas on a GaAs substrate. Compared with InGaAlP, GaAs material has

What problems may be faced by LED display screens produced by inferior LED display manufacturers?

With the rapid development of the automobile market in recent years, more and more green-brand cars can be seen on the road. These green-brand pure electric cars are jokingly called “electric fathers” by netizens. The reason for this title is that the car is originally an improved product that improves the convenience of our lives. It can liberate our legs and go anywhere anytime; However, due to the limitation of cruising range and imperfect charging facilities, electric vehicles have brought huge inconvenience to the daily use of car owners. Aside from the inconvenience of daily charging, even the necessary cold and warm air conditioning in winter and summer must be considered as car owners. Use it to give priority to ensuring the supply and guarantee of limited electric energy for driving mileage. As a travel tool, car owners cannot enjoy a convenient and comfortable driving experience. Like electric vehicles, LED

P0.7 or P0.9 small-pitch LED display which is more popular with people

Small-pitch LED display have been available for many years. As the most potential competitor in large-screen displays, small-pitch LEDs have replaced some of the DLP and LCD markets, and more and more are widely used in various industries. middle. With the development of science and technology, the small pitch of commercial applications has been promoted step by step from P2.5 to P1.0 to P0.7, and companies have launched small pitch products with the smallest known performance at P0.4mm. SMD and COB must be a topic that cannot be avoided when it comes to the technology update of small pitch. As we all know, in the small-pitch LED display industry, the SMD label market is relatively mature, and the COB small-pitch can only be said to be a rising star for various reasons. With 0.7mm pitch, it can display 2K resolution images on a 61-inch area. Such a display effect is

The advantages and disadvantages of COB packaged LED display and its development difficulties

COB packaging is a major advancement in LED displays in recent years. Thanks to the development of COB packaging technology, the dot pitch of displays is getting smaller and smaller. At present, high-end LED manufacturers have achieved 0.4mm dot pitch, but The problem is also very obvious. After all, there are some technical barriers, so the price is still relatively high. COB packaging integrates upstream chip technology, midstream packaging technology and downstream display technology. Therefore, COB packaging requires close cooperation between upstream, midstream and downstream companies to promote the large-scale application of COB LED displays. As shown in the figure above, it is a COB integrated packaged LED display module. The front side is composed of LED lamp modules to form pixels, and the bottom side is an IC driving element. Finally, each COB display module is spliced ​​into a design-sized LED display. The theoretical advantages of COB: 1. Design
