On April 25, Hisense Medical released the world's first 55-inch Mini-LED medical endoscopic display, which effectively solves the pain points of doctors with black and poor layering in the dark field under the surgical scene with excellent sense of field of field and stereoscopic sense. It is reported that this product of Hisense Medical has undergone 8 years of technology accumulation and 10 months of research and development.
As an indispensable device for minimally invasive surgery, the endoscopic display is known as the "jewel in the crown" and has the highest technical difficulty among the many categories of medical displays. The quality of the endoscopic display directly affects the operational efficiency of the surgical operation and even affects the surgeon's judgment of the lesion. With the release of this 55-inch Mini-LED medical endoscopic display, Hisense Medical has taken the lead in opening a new era of high-dynamic endoscopic display in the industry.
On the same day, Hisense Medical also released the fifth generation of "perioperative full business process management" intelligent surgical department overall solution.

Hisense Medical released 55 inches
Medical endoscopic displays
According to reports, hisense medical's endoscopic display uses Hisense's self-developed Mini-LED backlight module, which has achieved breakthroughs in contrast, color gamut, detail display, etc.: its contrast ratio is as high as 200,000:1, especially in the small and narrow cavity, presenting more in-depth organizational details, greatly improving the sense of screen layering, and effectively assisting doctors in identifying lesions and surrounding environments.
The product color gamut coverage rate of up to 85%, red color gamut 100% coverage BT2020 standard is the highest in the industry, perfectly present a variety of red needs in the voyeuristic environment, can effectively solve the doctor in the surgical scene, darkfield bleeding point is black and poor sense of hierarchy of surgical pain points, reducing the risk of surgery; in addition, its a variety of color independent adjustment, image enhancement function also improves the detailed performance of the display.
Dong Xuan, president of the Affiliated Hospital of Qingdao University, said: "The listing of hisense Mini-LED medical endoscopic displays has greatly improved the visibility of a large number of bleeding points and nervous system under surgical conditions, enabling the internal tissues of the cavity to be truly restored, achieving the same effect as the actual open clinical surgery, which can effectively reduce the visual fatigue of the doctor's surgical process and improve the efficiency of the operation." ”
It is worth mentioning that on the same day, Hisense Medical also released the fifth generation of "perioperative full business process management" intelligent surgical department overall solution. It is understood that the program has undergone many iterations and upgrades, integrated five major systems around the business process of the surgical department, covering 23 functions, and took the lead in the industry to achieve the intelligent integration platform management of the intelligent surgical department, ensuring safety while achieving the improvement of surgical efficiency.
So, what kind of opportunities and original intentions is Hisense Medical based on to develop this medical endoscopic display? In the process of product research and development, what kind of technological breakthroughs have been made? In this regard, Hisense Medical said that the release of the world's first 55-inch Mini-LED medical endoscopic display is not accidental, but its years of technology accumulation and deep demand insights are doomed.

Choose the new Mini-LED display technology
Resolve surgical pain points
In fact, Hisense Medical began to invest in the research and development of medical displays in 2014, and in 2016, the first generation of 26-inch 2K products, the first launch of 32-inch 4K products in 2019, and the launch of 55-inch 4K multi-partition backlight control endoscopic display products in 2021, gradually becoming a domestic first-line brand in the field of endoscopic displays.
However, after communicating with multiple doctors and following dozens of surgeries, Hisense Medical also found a new pain point, that is, in the surgical scene, the endoscopic display will have the problem of darkfield bleeding points being black and poor layering.
"It's like when a tunnel is lit, the light at the mouth of the tunnel is very bright, but the light in the tunnel is very dark, so there will be a difference from the actual situation." The same is true of the surgical process, which requires a sense of field and a sense of three-dimensionality. In the view of Hong Shengfeng, director of the Hisense Medical Medical Display Institute, the endoscopic display is displayed in a plane, but the existing technology is difficult to change, and it is necessary to choose an updated display technology to solve.
What technology is best suited? Thanks to hisense group's rich technology accumulation in the field of display, Hong Shengfeng and colleagues finally determined mini-LED as the solution of a new generation of endoscopic displays after comparing the characteristics of many display technologies such as OLED, stacked screen, Mini-LED and so on.
It is reported that Mini-LED, as a new display technology with high maturity, can be used to achieve high contrast, high dynamic range and color gamut coverage; more importantly, Mini-LED module backlight technology can solve the problem of depth of field.
It is worth mentioning that at present, the modules in the industry are purchased, and they do not have the ability to self-develop the Backlight of the Mini-LED module. Hisense chose a window that has not been opened in the industry, and thus broke out a different path from the industry, in July 2021, Hisense Medical officially began the research and development of 55-inch Mini-LED medical endoscopic displays.

Combined with the reference lighting algorithm
Industry-leading color accuracy
Whether it is a TV set or other products, picture quality debugging is like internal power, while the picture quality of medical display products requires a deeper foundation in display technology to achieve almost harsh tuning requirements.
Dong Jie, a picture quality design engineer at Hisense Medical Company, said that the complexity of picture quality debugging lies in the fact that the display effects of blood vessels, fats, tissues and so on in surgery need to be adjusted for picture quality, and it is necessary to comprehensively consider adapting to different surgical scenarios, and also adapting to the display effects and interface adaptability of different endoscopic manufacturers.
Although the Mini-LED endoscopic display has the highest BT2020 color gamut coverage of the industry's highest 85%, if the debugging is not accurate enough, it will have side effects, especially the red inside the cavity, and even the wider the color gamut coverage, the greater the deviation.
In the process of image quality adjustment, Hisense Medical uses the world-recognized high-end 24 color cards to compare one by one, combined with Hisense's reference light source algorithm scheme, so that the endoscopic display achieves the industry's leading color accuracy. However, it is not enough to achieve accurate color in the laboratory, but also to adjust the display effect and interface adaptability of different endoscopic manufacturers.
To this end, Hisense Medical tested in more than a dozen manufacturers across the country, and finally dismantled 40 machines to look at the differences one by one to see the difference, repeated verification, found the root cause of the problem and determined the appropriate program, the current hisense medical display can be adapted to different manufacturers of endoscopic products.

The R&D process encountered several challenges
Finally solve one by one to pick up the crown jewels
In terms of hardware, because the Mini-LED endoscopic display does not have a template that the industry can learn from, everything is starting from scratch, and Hisense Medical has also encountered multiple problems in the research and development process. However, after 10 months of research and development, hisense medical team successfully solved all the problems and finally took off this crown jewel.
Backlit module
According to reports, because Hisense Medical uses its self-developed Mini-LED backlight module, the distribution of energy, the uniformity of the product and the color gamut and other issues, every detail needs to be constantly polished.
In order to find a screen material that can meet the requirements of the color gamut and overcome the attenuation caused by high brightness, the R&D team repeatedly verified, discussed and found several times to communicate with the supplier before determining the appropriate solution.
Shield from static electricity
Unlike the simple use environment of ordinary televisions, there are many devices in the operating room, such as cutting electric knives, orthopedic chainsaws, and the use environment of endoscopic displays is more complex, and the use process is often affected by static electricity.
For household products, 8000V electrostatic test experimental products are not bad and acceptable, but in medical products, 8000V tests, there can be no image abnormalities, can not flash, and can not be black screen. This is also a huge challenge for the Hisense medical team, which is making a Mini-LED endoscopic display for the first time.
"When we first hit 8000V, the image was always black, and we began to check, from the signal source to the cable to the display, one by one to check the cause." In more than a month, after dozens of tests, rectifications, retests, and continuous optimization, the static test of the endoscopic display finally reached the standard requirements.
Electric knife interference
The electric knife is an important device for surgery, but it can also cause great electromagnetic interference to the endoscopic display.
Since there is no unified standard for anti-electric knife interference, the team has carried out a strengthened anti-interference design at the board level in accordance with the most stringent international standards to achieve multiple shielding designs. The wire of the electric knife is also wound around the display or module, and it is close to the display to simulate the interference problem to the maximum.
Finally, after two months of testing, Hisense endoscopic display can resist 8000V contact discharge and 15000V air discharge in terms of anti-interference, ensuring that the image will not be abnormal in the case of interference, and Hisense Medical has also taken the lead in the industry to master the design technology of Mini-LED anti-interference.
In addition to anti-interference, Mini-LED medical endoscopic display adopts a dual power supply structure, any power board suddenly has a problem, and the other power board seamlessly backs up and switches to ensure that there will be no abnormal performance during the operation, and there will be no downtime, reaching the stable and reliable requirements for the endoscopic display in the surgical environment.
