With the advancement of the wave of electrification and intelligence in automobiles, digital cockpit has become the core track of automobile competition, and the TFT display screen in the car center control, as the "interactive core" of the digital cockpit, directly determines the driving experience and driving safety. Currently, the TFT display screens for in car central control are rapidly iterating towards three directions: high brightness, wide viewing angle, and high reliability. However, the industry is generally facing a pain point: how to simultaneously meet these three core requirements and avoid "neglecting one and losing the other"? ESEN has been deeply involved in the field of in car displays for many years, focusing on the research and supply of in car central control TFT display screens. With profound insights into in car scenarios, mature technological accumulation, and practical experience, combined with current trends and technical standards in the in car display industry, this article will comprehensively dismantle the three core trends of in car central control TFT display screens, helping car companies and in car terminal manufacturers accurately grasp trends and select suitable in car central control TFT display screen products.
1、 The three core trends of TFT display screens in car central control: why have they become mandatory?
Unlike consumer electronics and industrial control scenarios, in car central control TFT displays need to cope with complex environments such as strong light exposure, multi view viewing, high and low temperature fluctuations, vibration impacts, etc. for a long time, while also considering smooth interaction and driving safety. This also determines that high brightness, wide viewing angle, and reliability have become the core development trends of current in car central control TFT displays, and are also the core considerations for car manufacturers in their selection. Based on data from the in car display industry and practical experience with ESEN, the specific manifestations of the necessity of the three major trends are as follows:
1. Highlighting: Dealing with strong light in the car to ensure driving safety. The TFT display screen of the car's central control needs to be adapted to outdoor strong light environments (such as exposure to sunlight at noon). If the brightness is insufficient, problems such as screen reflection, unclear navigation, and operational failure may occur, seriously affecting driving safety. According to the industry standards for in car displays, the brightness of the current in car central control TFT display screen has been increased from the traditional 500nit to 800-1500nit, making high brightness a must-have - this is also one of the core optimization directions for ESEN in car central control TFT display screens.
2. Wide viewing angle: Suitable for multi scene viewing, enhancing driving experience. The viewers of the in car central control screen not only include the driver, but also the co pilot and rear passengers. The viewing angles from different positions vary greatly. If the viewing angle is too narrow, problems such as color cast, dimming, and unclear visibility may occur, which cannot meet the interactive needs of multiple passengers. Based on industry trends, the current high-quality TFT display screen for car infotainment needs to achieve 170 °+full angle display, ensuring clear and uniform images from any angle. This is also one of the core differences between car displays and ordinary consumer electronics displays.
3. High reliability: Suitable for complex environments in vehicles, extending service life. During the driving process of a car, the TFT display screen in the car's central control needs to withstand complex environments such as high and low temperature fluctuations (-30 ℃~+80 ℃), vibration, dust, and humidity. At the same time, it must support long-term stable operation for 7 × 24 hours. If the reliability is insufficient, problems such as black screen, lagging, and damage may occur, affecting the driving experience and increasing after-sales costs. Therefore, industrial grade reliability has become the core hard indicator of TFT display screens in vehicle control systems, which must comply with relevant IEC industry standards.
ESEN Reminder: In the current TFT display industry for car infotainment, most products can only cater to 1-2 trends, making it difficult to achieve synergy among the three - for example, high brightness products often have high power consumption and insufficient reliability, wide viewing angle products are prone to brightness loss, and high reliability products are difficult to balance display effects. ESEN has achieved synchronous implementation of high brightness, wide viewing angle, and reliability of the TFT display screen in the car center control through technological optimization and process upgrading, perfectly adapting to the high-end needs of the car's digital cockpit.
