"Zhang Yimou understands the romance of Chinese too well." Just after the opening ceremony, director Zhang Yimou rushed to the Weibo hot search list.
People were amazed – every frame of this opening ceremony was beautiful. Indeed, the opening ceremony stunned the world with atmospheric and beautiful pictures and clever creativity, showing a beautiful picture of China where humanities and science and technology blend.
Crystal clear ice and snow five rings, romantic and beautiful snowflake torch platform, dazzling digital light and shadow... These beautiful pictures that cannot be forgotten for a long time are not only due to the ingenuity of Chinese, but also to the strong technical support of Chinese technology companies in the field of display and Internet of Things.
Jingdong Convenience is one of the powerful "behind-the-scenes forces" of this magnificent and romantic opening ceremony. From the main torch platform that amazed the global audience, the world's largest 8K ultra-high-definition ground display system, to the 8K ultra-high-definition display screen and volunteer digital badges that could be seen everywhere during the entire event, BOE's display technology and Internet of Things technology were released on the global attention platform. "The opening ceremony is the most perfect, most direct and most extensive display of the Internet of Things strategy for our screen." BOE chairman Chen Yanshun said.
550,000 independently controllable LED lamp beads create a beautiful and romantic "snowflake" shaped torchbear
Ignition is the finishing touch at every opening ceremony. At the opening ceremony, the giant "snowflake" shaped main torch platform shone with a crystal clear light and slowly lifted off, accompanied by the ignition of the holy flame, and the atmosphere of the entire opening ceremony was also pushed to a climax.
So, how did this crystal clear "snowflake" come about? The author understands that IT is BOE, a leading enterprise in the global semiconductor display field, independently designed and realized the "snowflake" shaped main torch platform. This creative torch stand consists of 96 double-sided small snowflake screens and 6 double-sided olive branch screens, representing 96 participating countries, and the double-sided hollow LED special-shaped full-color display is composed of about 550,000 pixels.
Special-shaped design, independent programming of each lamp bead, the snow screen out of the light surface as narrow as possible... To realize the director's idea of "snowflake crystal clear, diamond-like brilliant effect", BOE needs to overcome a series of design and technical difficulties. After designing more than 500 drawings and making nearly 10 rounds of samples, the core R&D team of BOE finally succeeded in landing the creativity of the director group.
From a technical point of view, each of the 550,000 LED lamp beads has realized independent control by a single channel of the driver chip, and the width of the hollowed-out snowflake is controlled at 4.8mm, which also makes it the narrowest single-pixel controllable LED special-shaped display product in the industry, filling the gap in the industry.
If the hardware design of Snowflake Screen is very creative and innovative, then the software system reflects a high degree of reliability. When the sacred flame is lit, the snowflake screen radiates from the center to the surroundings, shining a wave-like layer of brilliant light, which involves the rapid transformation and instant synchronization of the display picture.
With the support of BOE's AIoT technology system and the self-developed same/asynchronous compatible information and distribution system, asynchronous centralized control can quickly deliver large-scale video content in a very short period of time, and synchronous centralized control ensures that 102 double-sided screens achieve millisecond response; in addition, the highly redundant control system backed up by "main road + loop" ensures the ultra-high reliability of the torch station broadcast control system. At the same time, by using the LoRa (long-range radio) low-latency control system with synchronous playback time correction technology, it further ensures that the instruction is issued foolproof and realizes the perfect coordination of video pictures.
The beauty in the director's heart is restored to the truth, so that hundreds of millions of viewers around the world can truly feel such beauty, which not only reflects the understanding of BOE, but also highlights the scientific and technological power of BOE.
The world's largest 8K ultra-high-definition terrestrial display system creates a dream digital stage with glittering colors
The grass revived, transformed into a huge dandelion, the little boy gently blew, the dandelion flew away from the ground; a little ink dripped, transformed into the rushing weather of "the water of the Yellow River from heaven", pouring down from the "bowl mouth" of the bird's nest, covering the whole field; roller skaters flew with the music, and the roller skaters under their feet pulled out the motto of "Faster, Higher, Stronger, and Together" on the ground display...
These beautiful scenes were staged repeatedly at the opening ceremony, and the stunning visual effects shocked the world. "We made the world's largest light and shadow screen this time, equivalent to 15 IMAX movie screens." Wang Zhiou, visual effects director of the opening ceremony, said proudly in an interview with the media.
As Wang Zhiou said, such a huge light and shadow screen is actually a complicated digital innovation project, which requires scientific and technological aesthetics and technical means to complete it. The author understands that such a large-scale ground display system, including ultra-high-definition display, big data processing, low-latency transmission synchronization, security and reliability, etc., also comes from BOE.
This display system is very "big". It is understood that the overall display system has an overall area of more than 10,000 square meters, consisting of 40,000 LED screens, and the total length of ground cables exceeds 20 kilometers.
8K Ultra HD is the highlight of this large-area display system. BOE adopts a number of 8K+ resolution picture fusion technology, through the ultra-large-scale optical correction algorithm, can be pixel-by-pixel level light correction of the display screen, and finally reach 100000:1 ultra-high contrast ratio, 3840Hz ultra-high refresh rate, and 29900x15096 ultra-high resolution.
At the same time, the display system also shows a high degree of synchronization and fluency. Relying on the ultra-large-scale display module control and synchronization system independently developed by BOE, the transmission delay of the overall link signal from the source to the display terminal is less than 2 frames, which achieves the effect of no delay in visual and shooting. At the same time, the system has GenLock physical synchronization clock mechanism technology, which can realize frame-by-frame synchronous transmission between the signals at the playback end, avoiding delay problems such as frame skipping, stuttering, flickering, and jitter, and maximizing the creative effect of visual materials.
In terms of reliability, BOE has done its homework in both software and hardware. In terms of hardware, it can withstand more than 5,000 high-intensity pedaling and can withstand the extreme low temperature of minus 30 degrees Celsius; in terms of software, independent AB two-way dual systems are designed on power supply, signal, drive and display components to ensure that nothing is lost.
As a leading display panel enterprise, although the display system has always been the strength of BOE, but to create the world's largest 8K ultra-high-definition ground display system, to create a glittering dream digital stage, such a super cutting-edge technology integration ability and innovation landing ability will still be amazing, BOE thus also to the world perfectly show the style of China's technology leaders.
With the blessing of Internet of Things technology, volunteer badges have realized intelligent digital "generational" innovation
The power of science and technology is not only displayed in the beautiful picture of the opening ceremony, but also hidden in many details of the event service.
Volunteer service is an important guarantee for the smooth progress of the event. It is reported that at present, all 758 sites of urban volunteers have "opened their doors to welcome guests", and more than 40,000 urban volunteers have taken up their posts to serve. As the badge of volunteer identity, with the help of BOE display technology and Internet of Things technology, "generation-oriented" innovation has been realized.
Whether the traditional badge is made of paper or plastic printing, it cannot change the content and cannot be used twice, which is not in line with the trend of low-carbon environmental protection. The author noted that the volunteer badge adopted the smart digital badge customized by BOE, which very well explained the concept of science and technology and green.
Specifically, this digital badge has three major features:
The first is to be greener and healthier. It adopts a 3.7-inch electronic ink display to achieve extremely low strobe, the greatest care for the health of the eyes; cancels the built-in battery, does not need wiring to charge, and uses the NFC function of the mobile phone to communicate and take power; the fuselage adopts medical antibacterial materials and can be washed with water.
The second is to be both personalized and artistic. With the support of BOE's self-developed AI algorithm, it is possible to edit and quickly refresh the combination of graphics and text through the exclusive App. At the same time, it has a strong picture processing ability, can convert photos into vector maps, users can personalize settings according to image granularity, clarity, etc., and can automatically cut out portrait pictures. In addition, unlike ordinary electronic ink screens that can only present black and white, this digital badge can achieve black, white and red displays, which can highlight the artistry of the graphic picture.
Third, the production is simple and convenient. With the NFC function of the mobile phone, the transfer of edited content can be completed by simply touching the badge and the mobile phone, and it takes only 10 seconds from card making, card swipe to card collection, and can be recycled and reused.
In fact, the volunteer digital badge is only the "tip of the iceberg" of BOE's IoT technology innovation. In fact, in many application scenarios such as office, supermarket, travel, etc., BOE has created a soft and hard fusion solution based on paper-like eye protection display many years ago, becoming a market and technology leader in the field of electronic price tags and signage. In addition, in the field of Internet of Things such as smart finance and smart retail, BOE has also created an overall solution and become a world-leading Internet of Things technology company.
An excellent director who understands romance, an excellent enterprise that understands science and technology, their efforts and achievements, under the illumination of the holy flame, have become the best performance of self-improvement, self-confidence and self-reliance in contemporary China.
