With the development of technology, vehicle multimedia becomes more and more diversified, and LCD screens are used more and more in automobiles. From the centralized multimedia navigation system to the rear entertainment system, even now the dashboard and rearview mirror are beginning to be replaced by LCD. What is the difference between a car screen and a mobile phone or computer screen? The car LCD screen can work in extreme temperature.
Why should the car screen withstand high and low temperatures?
First, the working environment of vehicles is relatively complex. Sooner or later, spring, summer, autumn, winter, whether in different parts of the world, or when we need a car to work. The car will be sunburned in summer, the temperature is very high, the car's electronic components must be able to work with the car, not a problem. In some northern areas, the winter is very cold, and ordinary LCD screens can not work. At that time, we need high and low temperature LCD screen to display the driving information and escort the car owners.
Now LCD screen technology has become more and more mature. More and more automobile LCD screen applications today, LCD screen has been able to fully meet the changing working environment and working requirements of automobiles. The LCD screen has made a great change in the application of automobile. When technology products enter the manufacturing industry, but finding direction, the speed of development will be quite rapid.
International safety test
According to the national standard, all parts of the automobile need to be tested for 10 days, which can completely detect the performance of the test device.
For LCD screen, ISO automotive electronic reliability test and related standards of LCD screen test standards have relevant provisions. It can be seen that the requirements of LCD panels are very high. Under extreme conditions from minus 40 degrees to 105 degrees, you must work well for more than 300 hours.
Difficulty
High-brightness LCD screen in extreme temperatures to achieve normal work at the same time, but also in the ultra-bright direct sunlight visible, waterproof. And the LCD module's GPU, display screen and so on will be heated during the use. The higher the resolution of LCD, the greater the calorific value. So finding or developing suitable hardware products for the use of the vehicle environment, matching a set of hardware environment to meet the requirements of vehicle use, is also a technical difficulty for the research and development team. Because of these reasons, so compared with mobile phones, television and other display resolution, car display screen to do more conservative.
Now LCD screen technology has become more and more mature. More and more automobile LCD screen applications today, LCD screen has been able to fully meet the changing working environment and working requirements of automobiles. The LCD screen has made a great change in the application of automobile. When technology products enter the manufacturing industry, but finding direction, the speed of development will be quite rapid.
