Recently, the reporter interviewed a number of auto parts enterprises at home and abroad on the development trend of auto display screen. They have said that high-definition large screen, integration and intelligence are the development trend of automobile display in the future, and with the deepening integration of Internet technology and automobile technology, automobile display will bring more and more convenient functions and experiences to drivers and passengers.

　　The era of HD large screen integration is coming

　　"First, the screen size becomes larger, reaching 10 inches or more, and more HD (1080p) At the same time, OLED electromechanical laser display, touch screen, curved screen and other new screens will appear in cars one after another; second, multi screen integration, which mainly refers to the function of internal host integration; third, in addition to the optimization of display, the functions are more comprehensive, such as real-time online; fourth, new display technologies such as naked eye 3D and real scene enhancement will be applied. "Recently, Zhu Guangwei, vice president of Bosch Automotive multimedia division in China, introduced the development trend of automotive display screen to the reporter of China Automotive News.

　　At present, some high-end cars use oversized display screens, such as the second generation Volvo XC90 and Tesla Model s. Zhu Guangwei believes that in the era of automatic driving, there will indeed be a demand for larger display screens. It is certain that large HD screens are the development trend in the future. However, from the current user experience, the large screen is not a good thing. The screen is the presentation carrier of HMI (man-machine interface). The size of the screen should match the displayed content and functions. We can't blindly pursue the large screen for cool. Duan Yongzheng, deputy general manager of Desai Xiwei, also believes that the Tesla large screen is actually very abrupt in terms of aesthetic modeling, and the size needs to match the interior modeling of the whole vehicle.

　　Zhu Guangwei believes that the central control screen will integrate more control functions, and human-computer interaction can be realized in a variety of ways, including gesture, touch, vision and hearing. In the future, many ways will be combined with each other, and in this process, the on-board display will play an important role. In addition, the integration of on-board display also has many advantages. First, it integrates practical functions such as entertainment, social networking, information and navigation, which not only improves driving fun, but also provides convenience. In fact, it also indirectly improves safety; Second, cost reduction; Third, it brings the possibility of various design styles.

　　For the application of new technology in reality, Zhu Guangwei told reporters: "at present, the popularity of touch screen is very high, and the probability of front installation is also very high; HUD (head up display) In the rapid promotion period, the advantage of this technology is that the information is displayed in front of the driver, the driver's line of sight can not leave the driving direction, and the safety can be greatly improved; for human-computer interaction, different enterprises adopt different implementation methods, such as gesture, voice interaction, iris recognition, etc. "

　　"Strategist's important place" for Vehicle Enterprises

　　Duan Yongzheng said that in addition to display, the on-board display also takes into account the control function. In the future, there will be more and more electronic devices for the whole vehicle, and there will be more and more requirements for display, reminder, networking and control. It can be said that the on-board display screen will become the "battleground" of vehicle enterprises and gradually become the standard configuration.

　　At present, global auto companies are competing for the auto display market. Europe and the United States mainly focus on control systems. The vehicle touch screen market is controlled by automobile console component manufacturers such as mainland China, Bosch, Ford and Johnson Controls. The Asia Pacific region is a game of vehicle touch screen, mainly provided by Panasonic, alpai and other enterprises. IHS, a market research institution, pointed out that the overall output value of global automotive displays is expected to rise sharply from more than US $9 billion in 2015 to US $18.6 billion in 2021, more than double. Among them, the central control screen accounts for nearly half of the proportion, and the output value of HUD has the strongest growth.

　　Chen Jianhai, general manager of Anhui jinhaida Automotive Electronics Co., Ltd., believes that the future market space is mainly reflected in the instrument and central control system, entertainment and communication office system. However, the key technologies are controlled by foreign investors such as Bosch and the mainland, and there are still problems in the reliability of LCD technology in China.

　　"Intelligent automobile is imperative, and the first sign of intelligent automobile is to configure the automobile with a liquid crystal display, just like the transformation of mobile phone from function machine to intelligent machine." Duan Yongzheng told reporters that in the initial stage, technical difficulty and cost will be an obstacle, but with the increase of assembly volume, the cost will also decline. In fact, the central control screen has been gradually assembled on medium and low-grade vehicles. I believe that in another 2-3 years, the central control screen will be fully popularized, but the popularization of full virtual instrument screen will be later.

　　Will the central control panel and instrument panel merge into one?

　　2015 Audi TT abandons the central control display and displays all information on the instrument screen. Many people suspect that the central control panel and instrument panel will merge into one?

　　Zhu Guangwei told reporters that if the vehicle enterprise must combine the instrument panel with the center console, it can be realized technically. However, it still depends on the definition of vehicle design and style by the vehicle manufacturer.

　　Chen Jianhai believes that the central control panel is an auxiliary role relative to the instrument panel. The instrument has a lot of vehicle driving information to display, involving many safety factors and regulations, which is essential and has high reliability requirements; The central control screen displays entertainment and driving comfort information, which is neither necessary nor mandatory by laws and regulations, and has low reliability requirements. However, as a personalized selection and function realization, all functions of central control can be realized on the instrument panel.

　　Duan Yongzheng also said that the two sides have their own division of labor. The area where the instrument panel is located is more convenient for the driver to watch while driving, but it cannot be seen by other members in the vehicle; The location of the central control is suitable for information sharing, so multimedia information is suitable to be displayed here.

　　From the perspective of operation, the instrument screen cannot support touch operation (separated by the steering wheel in the middle), and can only be operated simply through the steering wheel button; The central control screen can do complex operations through touch (or even proximity sensing). At present, the two can exchange and share information and cannot replace each other for the time being. However, if the real driverless era comes, the function and position of the display screen in the car will be reconstructed, and a new product form will appear at that time.
