What are the parameters that need to be met by touch displays used in aerospace?
As an important display and interaction technology, touch displays have a wide range of applications in many harsh industrial environments. Whether it is used in ships, aircraft, vehicles, or used in communications equipment, radar systems, aerospace and other fields, the touch display needs to meet a series of specific parameters to ensure that it can work stably and reliably in complex, harsh environments.
The following are some of the important parameters that need to be met by the touch display:
1, High reliability
Touch display needs to have a high degree of reliability, can be in harsh climatic conditions, high temperature, low temperature, high humidity, low humidity and other environments in normal operation. In the aviation field, the LCD screen may face severe vibration, shock, electromagnetic interference and other environments, so its components and structure need to be rigorously designed and tested to ensure its anti-vibration, anti-shock, anti-interference and other properties.
2, High brightness and high contrast
LCD screen needs to be able to clearly display information in a variety of light conditions in aviation applications. Therefore, the touch screen needs to have high brightness and high contrast to ensure that in the glare, low light and other complex environments can clearly display images and text to meet the needs of pilots operating aircraft.
3, Wide temperature range
Touch screen needs to be able to work in a wide range of temperatures in aerospace applications, including extreme high and low temperature environment. In high temperature environments, the LCD screen needs to have better thermal stability to avoid display degradation, circuit failure and other issues; in low temperature environments, the LCD screen needs to have a better low-temperature start-up performance to ensure that under low temperature conditions can be normal boot.
4, Fast response
Touch screen needs to have a fast response characteristics to meet the real-time requirements. In aerospace applications, the LCD screen may need to display high-speed movement of the target, complex images and video and other content, so it needs to have a high response speed to ensure that the picture is smooth and stable.
5, High resolution and wide viewing angle
Touch screen needs to have high resolution and wide viewing angle characteristics. High resolution can provide a clearer, more detailed images and text display, which helps the operator to more accurately obtain information; wide viewing angle to ensure that different viewing angles can see clear images, to adapt to the complexity of aviation, multi-angle use of the scene.
6, Anti-reflective and anti-glare
In aerospace applications, the touch screen may face strong sunlight and other light sources of interference, so it needs to have anti-reflective and anti-glare characteristics to ensure that in the bright light environment can also be a clear display of images and text, to avoid reflections and glare on the operator caused by the trouble.
7, Anti-pollution and corrosion resistance
In aerospace applications, the touch screen may face a variety of pollution and corrosive substances, such as dust, oil, beverages, etc., so it needs to have anti-pollution and corrosion resistance to ensure that the long-term stable operation of the LCD screen and display effect.
8, Low power consumption and high maintainability
Touch screen needs to have the characteristics of low power consumption to save power and extend battery life. In addition, the LCD screen should also have high maintainability, easy to repair and replace to ensure reliability and stability in the aerospace panel.
