Shenzhou-13 was successfully launched in October 2021 and returned in April 2022, after 183 days.

Looking back on these 183 days, a series of events including the continuation of the epidemic, the Russia Ukraine war, plane crashes, and China's great rise caught us off guard.

Three astronauts far away in space, carrying the dream of our motherland's space exploration, exploring the mysteries of the sky!

Fortunately, the development of technology has made outer space fully connected to Earth, allowing them to experience things on Earth together with us through "space lectures" and various information display boards inside the cabin.

Using a display screen as a medium, open space teaching through the display screen

On December 9, 2021, the first lesson of "Tiangong Classroom" officially began. Using the display screen as a medium, "Space Teaching" has been launched.

Space teachers Zhai Zhigang, Wang Yaping, and Ye Guangfu brought a wonderful space science popularization class to young people on the Chinese space station.

Due to the distance between heaven and earth, this "Tiangong Classroom" will be conducted through "online classes". Both astronauts and students on the ground, as well as spectators, will need to use various information display boards inside the cabin
Multimedia device interaction.

On the Tianhe core module of the "Classroom" this time, 7 sets of equipment including intelligent displays, display screen components, keyboards, power accessories, etc. frequently appeared, which are the basis of "Tiangong Classroom" and "barrier free communication"
Basic hardware support.

Saishida Technology specializes in researching display equipment products suitable for the aerospace field, with the ultimate requirements for screens in various information display boards inside the spacecraft

The various information display boards inside the spacecraft have extreme requirements for the screen, firstly stability, secondly good signal, to ensure clear and stable images, and the display equipment itself must also withstand the test of space
Various tests. Saishida Technology is the first in the industry to develop and promote a series of technologies including high-efficiency backlight module design, ultra-thin backlight module technology, high color gamut display technology, quantum dot display technology, etc
The technical plan aims to promote continuous innovation in terminal display products in terms of light efficiency, color gamut, dynamic contrast, energy conservation and environmental protection, and appearance design. The research and development of quantum dot technology and optical enhancement film materials are also being utilized,
Enable the Saishida display module to have stable and bright images, specifically designed for exploring outer space in the aerospace field.

The biggest challenge faced by displays used in space is the severe vibrations and impacts generated during spacecraft launches, followed by the vacuum environment of space and large-scale temperature changes; Additionally, in space
There is strong spatial radiation, which is a continuous accumulation process. Even if the core cabin blocks most of the radiation, the chips of ordinary electronic devices will be damaged by a small amount of radiation; Finally, in this regard
Taking the Tianhe core module of the course as an example, this module needs to reside in the universe for a long time, and the research and development equipment has a lifespan of at least 15 years in orbit. This also puts forward requirements for the power consumption and endurance of the equipment, and various factors make the display
Screens must have special considerations in terms of design and materials. Saishida Technology is committed to developing efficient, energy-saving, low-carbon and environmentally friendly LCD display modules, which can save about 10% energy under the same parameters, making it a leader in the aerospace industry
Domain provides the most practical products and advanced technical services.

LCD screens were used in the Tiangong-2 laboratory and the Shenzhou manned spacecraft that docked with it as early as 2016, but at that time, the display devices were all mechanical buttons, making pressing operations extremely inconvenient.
As is well known, the spacecraft is located in the outer sky, and the environment is completely different from that on Earth. In the weightless environment of the spacecraft, all items inside are in a floating state, so all items are in compliance with regulations
The ranking is good.

For this reason, the display screen inside the spacecraft adopts an LCD screen instead of the traditional button based display control panel, which facilitates the daily operations of the three astronauts in the spacecraft. Simplified display device operation
Clean and efficient, the 7 sets of LCD instrument displays, information commands and other control equipment provided for the Tianhe core module this time have a new generation of space station human-machine interaction system, equipped with input devices such as keyboard and mouse
Standard and voice input modules, especially the first use of touch screens in aerospace, can achieve high-definition display while completing corresponding commands in a "hand swipe" manner; Meanwhile, the intelligent display
The display also has voice interaction function, allowing astronauts to switch display pages and communicate with the ground through voice. Saishida Technology focuses on developing "hand swipe" and touch display
Module to better adapt to human exploration and exploration of space!

Compared to the traditional button control of the International Space Station, the human-machine interaction experience of smart displays has made a qualitative leap, and astronauts can operate like smartphones, swiping back and forth.

In addition, as long as the core module is in orbit, the intelligent display becomes a computer. By searching for network resources, one can watch movies, short videos, information, listen to online songs

The Chinese nation is a nation that is brave in innovation. Our exploration of the universe has not stopped, and our development of aerospace products will accompany the footsteps of astronauts towards deep space. Saishida Technology will continue to develop lunar technology
Display equipment products related to ball exploration and Mars exploration human-machine interaction systems.
