Does the LED display industry really need 8K resolution?

As an important reference factor of LED display, high resolution determines whether the display is HD or SD.

Looking at the current LED display industry, under the background of industrial innovation, structural upgrading and scientific and technological revolution, the display technology has experienced several innovations and changes. LCD has replaced the CRT era and turned to LED as the important development direction of the industry focus. Digitization, networking and intelligence have been deeply developed and applied. In terms of consumption, people's endless pursuit of beauty, truth, details and what you want is also an important driving force for the development of the display industry. Do you know how much it costs to rent the led stage screen?

"In the process of previous display technology progress, 8K UHD is the most suitable for people's pursuit of real world visual experience, and the UHD display represented by 8K is a new round of major technological change after digitalization, intelligence and high-definition," said Hao Yabin, secretary-general of China Electronic Video Industry Association.

What can 8K bring?

As a new ecology, 8K is generally recognized by the industry as "larger and larger", "higher and higher resolution", "more and more clear display", etc. Wang Cheng, CEO of TCL Industrial Holding Co., Ltd., also said that the general trend of the display industry is to combine higher resolution and larger size to bring better experience to users, while driving the whole industry and even the whole society forward. "In 2013, 4K began to enter the industry, and gradually entered the family, and the TV size also reached 40 inches; in 2019, it is expected that the Chinese market display size will reach 51 inches, and 8K will gradually enter the family, and the overall size will further expand in the next five years. In this process, 8K will bring us a rapid increase in market penetration. It is believed that by 2025, the penetration of 8K products will reach 59%."

In addition to the size, 8K will also promote the upgrading of the display industry. "Including the display panel, the resolution of 8K is 4 times that of 4K and 16 times that of 2K. It will gradually turn 120Hz into the standard configuration of the product, including the transmission channel. At this time, 5G will also bring us new opportunities," said Wang Cheng, "This also includes the production of content, including artificial intelligence, 8K and many other new technologies, which will further enrich 8K content under the content production of multiple media such as film and television companies, thus forming a more complete industrial chain from content to the whole machine."

What is lacking in 8K?

As mentioned above, 8K's technology is not just coming alone. It brings a wave of new technology integration changes, bringing people more opportunities to move towards the era of full scene intelligence. So, what is lacking in 8K technology that can bring many possibilities at this stage?

"At present, 8K still faces many problems. The first is the problem of standards." Zuo Bo, general manager of the product center of TCL Industrial Holding Co., Ltd., mentioned that there is no complete 8K standard in the industry at present, so there is no complete set of standards for display, image quality processing, or content encoding, decoding, transmission and other channels. "So we see that there are a lot of products that may need to connect several HDR to display a complete 8K image, and even some products, even if connected, may not be able to achieve a real 8K display effect, but only a part of it." Zuo Bo hopes to promote the establishment of the entire industry standard of 8K through relevant industry associations and other organizations, and jointly pass the industry standards and specifications, To provide consumers with a product and service that can enjoy truly high-quality 8K images.

In addition to the urgent need to unify standards, the challenges faced by 8K also require attention to user experience. Liu Qian, Dean of the Digital Media School of Beijing Film Academy, mentioned that manufacturers are really pursuing perfection and limit in terms of product quality and precision, and the direction is really good. "But I think, should we pay more attention to user experience?" Because 8K is presented to the terminal by people. As the pixels get higher and smaller, the problem is that the best viewing distance is getting closer and closer. "Are we going to add pixels all the time now? I think it is enough for pixels to reach a certain limit, not to say that the smaller the better. Integrated circuits are not for people to see, but functional. Our display is ultimately to have user experience, so your 8K product design should be consistent with the viewing distance, and should be combined with the user's actual experience to promote innovation."

In addition, when referring to 8K, Liu Shuqing, chairman of Lerong Group, talked about the lack of content. "In 8K, the industry is generally faced with the reality that film sources are relatively scarce". In the face of new challenges in the field of content production, talent training has become an urgent matter. The action plan proposes to combine training and introduction, strengthen the construction of the talent team in the ultra-high definition video industry, and cultivate a number of high-end, composite leading talents. We will encourage industry university research cooperation, support colleges and universities to strengthen the construction of disciplines related to ultra-high definition video, and guide vocational schools to cultivate skilled talents urgently needed for industrial development. In this regard, Hao Yabin said that the China Electronic Video Industry Association and Beijing Film Academy jointly built an 8K digital content laboratory last April, which is an innovative attempt based on the consideration of training practical talents for the industry and enriching the industrial content framework.

Thank you for watching. I hope we can solve your problems. Sostron is a professional LED display manufacturer.

Animal Experience Station

Tells more about the research and development process of this project.

Project Description：

We inhabit the same world as animals, but humans all too often dominate their lives and impact their wellbeing immensely. Through daily observation as a city dweller, I noticed that there is far too much cruelty to animals surrounding us.

I hope that this project enables young urbal dwellers to experience the world of animals on a more intuitive level and through doing so create a new form of empathetic emotional bond with them. Whether one is the participant, or merely an onlooker, the project seeks to reduce the sense of 'otherness' that people often place on animals, as well as initiating re-consider the relation between human and animal, continuing a discourse within the field of non-anthropocentric design.

Process video https://youtu.be/tyBySdBgzs0

Inspiration：

I once saw chefs in restaurants making live octopus into dishes in front of diners and even let the diners ‘torture’ the live octopus and eat it. This restaurant in Shanghai is also very famous for this feature.

But this actually reminds me more of the performance death of animals.Humans and animals share this earth, but often treat them like this. :(

Due to this, I do some research on animal performance death in China. The truth is, this kind of news can be seen everywhere, such as hitting a sheep to death in front of diners, or eating live seafood live on a video app.

Though these news，I still remember that once I saw a live fish used as a video material in a shooting scene and was left and ‘tortured’ to death by people.

Also，I drew inspiration of two documentary. ‘Dominion’ By Chris Delforce

‘Racing Extinction’ By Louie Psihoyos

These two documentaries are very real about the harm that humans have caused to farmed animals and endangered animal. The ‘Racing Exhibition’ even predicted that ‘In the next 100 years, 50% of species will disappear. The biggest reason is because of human behavior.’

It leded me to think if we swap the position what will we feel? In that cases ,will we have a better understanding of them and emphasis with them？

In addition to second-hand research, I also conducted some first-hand research. I asked others if they would be able to empathize with animals, and the results showed that people are more inclined to empathize with pets or animals that are close in daily life (pigs/sheep). This instead reminds me of those wild animals, those animals that we rarely come into contact with.

Then，I went to Shanghai Wild Animal Zoo, where people can interact with wild animals and feed them. Now days a lot of urban residents will go here.

However， through observation, I found that as a urbal dwellers, I can only interact with these animals through cages and glass. This phenomenon gave me a deeper thinking about the relationship between urban residents and wild animals.

I also want to use this project to let people know the status of these animals.

Due to this thinking, I decide to do more research about the relationship between human and animal that I want to discuss.

Research

‘Tiger Penis Project’ By Kuang-Yi Ku

https://www.tigerpenisproject.com

I truly think this artist brought tradition Chinese views into the speculative design scene and proposed the use of emerging biotechnology to make artificial animal parts for traditional Chinese medicine. This new hybrid medicine combines Chinese and Western medicine with technology, prevents further destruction of animals and traditional culture, and provides more possibilities for the coexistence of human society and the natural environment.

‘I want delivery a dolphin’ By Ai Hasegawa

https://www.dezeen.com/2013/11/18/i-wanna-deliver-a-dolphin-synthetic-biology-concept-humans-giving-birth-to-food-by-ai-hasegawa/

‘This project approaches the problem of human reproduction in an age of overcrowding, overdevelopment and environmental crisis,’ Hasegawa said. "With potential food shortages and a population of nearly seven billion people, would a woman consider incubating and giving birth to an endangered species such as a shark, tuna or dolphin?"

This speculative and experimental design gives me a deeper thinking about the relationship between humans and animals. I also want to create a special experience to connect humans and animals. This is also about the field of non-anthropocentric design.

‘The School of Looking’ By Denis Connolly and Anne Cleary

http://www.connolly-cleary.com/Home/helmets.html

I was inspired by these artists, who mixed machine, human and animal experience together through a series of helmet designs, not only providing participant with an experience but also creating an interesting experience for on lookers.

Drawing upon this, I imagined a way of bringing people into the world of animals with a playful focus.

Through ‘Design events: on explorations of a nonanthropocentric framework in desig‘ By Li Jönsson, I found the helmet is a special form of speculative design，It's also a form of combining design and audience closer.

‘Song of the Machine’ By SuperfIux

https://superflux.in/index.php/work/song-of-the-machine/#

SuperfIux created a new type of retinal prosthesis, helping the blind to reconnect with the world. The device, in conjunction with an optogenetic retinal process, enables blind people to gain light sensitivity and therefore gain a field of vision.

My design proposal was influenced further through this work. I intend to design a wearable device that could alter our field of vision and create optical experiences which allow people to see the world through the eyes of animals.

‘Simulation is an important mechanism for empathy. Simulation is an ancient function of the human nervous system, which is of great significance in social life and individual development.’

From ‘Embodied simulation phenomena and neural mechanisms in empathy’, Chinese Journal of Clinical Psychology, Sun Yabin, Wang Jinyan, Luo Fei.

The above quote led me to consider whether simulation could be a design tool to connect humans and animals.

Additionally, a TED talk titled ‘How Virtual Reality Can Create the Ultimate Empathy Machine’ By Chris Milk made me reflect on the use of VR as a 'machine' to create simulation and change people's perspectives.

https://www.ted.com/talks/chris_milk_how_virtual_reality_can_create_the_ultimate_empathy_machine

Sorry for the unclear picture quality:(((((

Through this research, I decided to create a simulation visual experience for my audience to help them observe the world of animals and create a connection, with the aim of generating a deeper sense of empathy among humans for the lives on animals.

Though 134 questionnaires, I discovered that people were intensely interested in entering the world of animals. Also，after screening my survey results, I decided on the octopus, eagle, and snake as the animals I wanted to simulate the field of vision of, not only because people are curious about their vision, but also because these three animals represent the species that often be hunted from the ocean, land and the sky.

In addition，these three animals are also suffering some harm caused by humans. For example, in China we will regard snakes as important and drink liquor that made by snake. We do eat octopus raw and treat it as a pleasure. We did have some news about eagles being hunted and killed and they are on the verge of extinction.

‘RGB’ By Carnovsky

https://www.carnovsky.com/RGB.htm

The designer allows visitors to see different graphics through different colors of lighting, thus creating a visual space with a strong sense of experience.The space and the lighting have enhanced the experience.It also led me to think that use different color to change the audience visual experience.

Concept

Through all the research, I have finalized my concept. I am going to build a experience station that contain a series of wearable devices and enviroment to simulate the animal experience. Aiming to allow young urban residents to re-consider the relationship between human and animal, and pay attention to the current state of animals, finally empathize with them through a mixed experience.

Process of Helmets

The octopus can change the shape of its pupil to receive different colors of light.Theoretical source: https://octolab.tv/octopus- vision/

In the beginning, I did not deliberately decide on the shape of the helmet. I pay more attention to how to realize the conversion of visual functions, and I hope I can improve it later.

I even want people to simulate the living conditions of these animals before wearing my helmet, but later I hope that people will wear helmets to communicate and walk in this city in an playful way，I think the project seeks to reduce the sense of 'otherness' that people often place on animals, as well as initiating re-consider the relation between human and animal.

Lenses material：The lens is laser cut and spray-painted on the basis of colored acrylic to simulate the shape and color of the octopus pupil.

The angle of view of the eagle can focus and magnify a very small object with a light red color. Theoretical source:’Vision In Birds’ By Graham R Martin and Daniel Osorio

I tested the effects of magnifying glasses with different magnifications, and I finally chose a 15x magnifying glass, which does not make people feel dizzy but has a magnifying effect.

Lenses material: magnifying glass and translucent paper.

Snakes have very weak eyesight, but they can simulate images through heat sensing and through sensitive other senses.Theoretical source: ‘The Infrared ’Vision’ of Snakes’ By Eric A. Newman and Peter Hartline

Lenses material：At the beginning, I used simple graphics to experience the effects of VR, and the colors were generated according to the visual effects of thermal induction. Finally there will be a dynamic image of a snake in the VR glasses.

User Feedback

I tested these three helmets and got feedback from users and observers.

From the observers point of view, these helmets lack the feeling of three animals, and I need to add some texture and color to them.

From the user’s point of view, the helmet should be more ergonomic, and the use of lenses and helmets will not give people a sufficient sense of experience.

Because the visual effects of these three animals are quite special, I need some other products or environments to watch them in order to provide a better experience. Finally, I decided to make a series of posters.

Process of Poster and Logo

When designing the posters, I used the three primary colors of light (Red/Green/Blue) as the basis and designed patterns based on the visual characteristics of the three animals.

I also left short words on the poster in the form of a diary. For example, when visitors wear the octopus helmet, they can see different words by changing different lenses.

When visitors wear the eagle helmet, they need to use a magnifying glass to see the smaller words.

The snake poster itself has no information. But when visitors put on the snake's helmet, they can see a dynamic video with VR

Video link:https://youtu.be/tBUssmG6YjA

My helmet is mainly based on visual functions and has a role of changing perspectives. So the logo is based on the elements of ’eye’ and ’transition’.

I do some sketches and confirmed the final effect of logo

Second Prototype

Since the materials used in the previous helmet were not stiff enough, I remade it with corrugated paper.

Due to the limitation of the material, I used a better colored spray paint to decorate the helmet, but the finished product was not refined enough, so this became the second model. I pair these prototypes with posters to test the user experience, which will help me when I make the final outcome.

Process of final outcome

I re-adjusted the structure and decoration, using the three primary colors to redesign the color and pattern of the helmet. The pattern is processed in the simplest way according to the lines on the animal body, and the final outcome is performed by laser cutting.

User feedback:

1. The helmet is not easy for the user to wear with its current structure, so it needs to be considered more. 2. It would be interesting to get people to interact with each other when they have a helmet on, and it could be good to develop this into a performance and walk out onto the street to get more feedback. 3. More interactive devices can be designed, not just visuals, but other senses could also be incorporated. Currently, the experience of the animal is not strong enough.

Self-refIection:

1. The experience space could be set outdoors, allowing the audience to experience the animals' preferred habitats. 2. AR/VR and other technologies can be used to enhance the visual experience of different animals. So as to give the experiencer a more real experience. 3. Considering the scope and effect of communication, a visual branding system can be designed to integrate the helmet with the packaging and website.
