The birth of a Huawei smart screen
TV is a window for many post-80s and post-90s generations to know the world. Sitting together after dinner to watch the news and watch TV shows is an unforgettable childhood memory for many people. Today, the TV still firmly occupies the C position in the living room, but it has changed from black and white to color, from thick to thin, from a “small window” to a large screen.
From “TV” to “Smart Screen”
However, no matter how it changes, “TV” has always been its unified title. Until 2019, Huawei released a large-screen product and named it “Huawei Smart Screen”. This product is not only the first time that the name has changed from ordinary TVs, but also that it is separated from ordinary TVs in terms of function and positioning.
Huawei Smart Screen has the functions of an ordinary TV, and is a home smart interactive terminal driven by emerging technologies such as AI and IoT, providing users with a richer, smarter, and more personalized experience. As soon as the product was launched, it was well received by consumers, and it attracted a number of traditional home appliance brands to quickly follow up, launching smart screen products one after another, forming a new trend in the market.
In just a few years, Huawei’s smart screen products have released X, V, S, SE and other series, which are positioned as top technology, cinema audio and video, and young trends. Huawei has created a new category of smart screens, which has become synonymous with smart screens to a certain extent.
The story behind the screen
So why can Huawei Smart Screen compete with some established TV manufacturers? Obviously, the cameras added on the smart screen are not enough to answer all the questions. Let’s walk into the Huawei Smart Screen Lab together to explore the story behind the Huawei Smart Screen.
The screen is the facade of TV products, and it is also the biggest selling point of TV products. It can be said that the display effect of the screen directly determines the sales volume of the product. All TV manufacturers will spend their best efforts on screen display technology, and Huawei is of course no exception. Take Huawei’s latest Huawei Vision Smart Screen 86, for example, the Honghu image quality engine is a collection of Huawei’s achievements in screen display technology. It integrates the Quick Clear and Smooth Technology (MEMC) to improve the smoothness of moving pictures, and cooperates with 120Hz high refresh rate. The screen, for the 24-frame/30-frame film source with a relatively high proportion on the Internet, can solve the jitter phenomenon in the picture through intelligent frame insertion, making the picture more stable and smooth, especially when watching action movies, whether it is a speeding car. The chasing picture or the martial arts effect will be clearer.
The Huawei Vision Smart Screen Z e-sports version, which is designed for game lovers, takes the picture quality display technology to a higher level and fully adapts to the DCI-P3 color gamut specification, which can reach 92% DCI-P3 film-level wide color. It can better match all the color requirements that can be displayed in film and television works and game pictures, and bring consumers an accurate and restored picture quality experience. Combined with the clear light control technology, it can bring up to a million-level ultra-high contrast ratio, and supports up to 900nit HDR peak brightness, presenting vivid and bright details. In addition to color calibration, the factory-made smart screens are also color calibrated one by one, and the color accuracy is adjusted to DeltaE ≤ 2. The color of film and television works is not only rich, but also more accurate.
In addition to hardware guaranteeing the picture quality experience, Huawei has also applied many “black technologies” to improve picture quality on the upcoming new generation of smart screen V series. “Honghu computing picture quality” is one of them. With the super AI computing power of the network processor (NPU), Honghu computing image quality analyzes the objects in the picture in real time, performs intelligent perception and dynamic optimization of the pictures you see, and intelligently reshapes the texture details of low-resolution pictures and repairs objects. And the edge outline of the text, so that the contrast between the light and dark of the SDR content is stronger, the color is richer, and the color transition is smoother.
Such display technology looks very cool, and it is also very attractive in the introduction of the product. However, how can ordinary consumers confirm that the products they buy use these technologies, and how can they confirm that the display effects of these technologies are consistent with the publicity?
It turns out that there is a huge dark room in Huawei’s smart screen laboratory. On the screen of a smart screen product, various detection images such as solid color pictures of different grayscales, color scale transition pictures, and window pictures are displayed. On the opposite side are three One optical lens, one of which is a face shot lens, is mainly used for the rapid test of large-scale uniformity performance, which can improve the test efficiency; the other is responsible for testing optical content, such as brightness, color gamut, viewing angle, etc. up to more than 20 indicators , to ensure the optical parameter effect of the smart screen; the last one is responsible for testing the response time and flicker indicators.
In this experiment, like a tireless inspector, the display effect of each smart screen will be evaluated to see if it meets the design requirements. According to the relevant person in charge of the laboratory, this is a rare optical automatic test equipment in the industry that can cover the range of 30-110 inches. Engineers measure the brightness, uniformity, color gamut, viewing angle and other indicators that affect the user experience of the smart screen.
Audio Immersion Experience
Sound performance is another experience that TV products attach great importance to. Many of Huawei’s high-end smart screen products have even adopted joint tuning with the well-known audio manufacturer Divale for sound effects, in order to bring consumers an immersive home. Cinema feel. On the latest Huawei Vision Smart Screen Z gaming version, Huawei adopts an integrated SoundBar design with 6 built-in speaker units, 2 full-range units, 2 high-frequency units, and 2 woofers, and is designed for three frequencies. With a special acoustic design, it can bring a music experience with a wider frequency range and less distortion.
The audio laboratory of Huawei’s smart screen laboratory consists of a large wedge-type full anechoic chamber and a reverberation laboratory. The former can support the acoustic test of the smart screen electro-acoustic device and the whole machine, and is used for speakers, microphones, and complete machines. and other basic acoustic performance; the latter supports the objective test of the intelligent voice wake-up rate and false wake-up rate of the whole smart screen. Through technical cooperation with professors from top acoustic schools in the industry, Huawei has determined subjective and objective evaluation indicators related to immersion, and benchmarked production line test results with anechoic chamber results to ensure the sound field immersion experience of smart screen products.
“Reliable quality, thousands of hammers dig deep mountains”
“Bang dang! Bang dang”, before entering the reliability laboratory, he heard a loud noise from inside. After entering the office, the first thing that catches the eye is the smart screen products that are ready to be tested, just like soldiers waiting to be reviewed. Not far away, a large robotic arm is holding a packaged smart screen and smashing it on the steel platform. This is the source of the clanging sound. This scene is also shocking.
According to the person in charge of the laboratory, this is the indispensable reliability test area of Huawei’s smart screen laboratory, and the behavior of “beating” the smart screen is carried out hundreds of times every day. Because the smart screen must go through a series of processes such as warehousing, transportation, handling, and installation from the factory to the user’s home. The multi-layer stacking of smart screens in warehouses, bumps and bumps during long-distance logistics and transportation, and inevitable drops during turnover and handling all pose a challenge to packaging.
The packaging static press can simulate the ability of the large screen to withstand stacking in the warehouse storage process. Through the pressure test of multiple layers of stacking in the market, it is evaluated that the packaging is safe and reliable in major warehouses and partner warehouses across the country; large screen vibration, shock and collision The test platform can simulate the impact of the vibration of vehicles passing through speed bumps, potholes and long-distance transportation on the packaging during transportation; the packaging drop machine simulates the reliability of the whole machine during abnormal drops during the large-screen turnover and handling process. The drop height is adjusted according to size and weight, covering various abnormal scenarios.
In the other room, there is a huge environmental box that is more common in other electronic product laboratories, which can simulate the high temperature and high humidity environment that products may encounter in different regions, or salt spray corrosion in coastal areas, dry areas. The dust is a severe test for the quality indicators such as the sealing of the product.
Every smart screen product will go through a long testing process from the beginning of its design to the final launch, which can be called “a thousand hammers and ten thousand hammers.” Only in this way can this kind of large consumer goods with an average use of more than 5 years have reliable quality throughout the life cycle.
“Seeing is believing” in the laboratory returned to its original meaning. Because every brand invests a lot of money and manpower and material resources to build laboratories and purchase expensive equipment not for inspections or external visits, but to ensure the quality of products is the original intention.
Although, ordinary consumers do not often see the stories behind these products. However, the quality of the product is believed to be perceived by consumers in the process of using it. Those products older than their own age are not uncommon in life. The quality made in China also makes consumers more aware of domestic brand products. confidence. Huawei’s smart screen products have passed rigorous experimental testing and obtained guarantees for product technology and quality. On major consumer platforms, Huawei’s smart screen sales and consumer praise are the best compliments.
During this year’s Double Eleven, Huawei’s new annual Smart Screen Vision Smart Screen Z e-sports version also launched a large number of discounts. Excellent quality domestic products, may wish to consider adding to the shopping cart.
