Nowadays,car LCD screens are used more and more in our lives.Do you know what are the requirements for car LCD screens? The followings are the detailed introductions:
①Why should the car LCD screen be resistant to high and low temperatures?
First of all,the working environment of the car is relatively complicated.Cars are required to work, morning and evening,spring,summer,fall and winter,in different regions around the world.
Cars are often exposed to the sun in summer,and the temperatures in the cabin can reach more than 60°C.The electronic components in the car must be able to work normally with the car.
In some northern regions,the winter is very cold,and ordinary LCD screens cannot work.
At these times,a liquid crystal display screen that is resistant to high and low temperatures is needed to display driving information for car drivers and escort them.
②International Safety Testing Standards
According to the rigid regulations of the national standard, all parts of the car need to be tested for 10 days, which can completely detect the performance of the test device.
Among them,for vehicle-mounted LCD screens, the LCD screen test standards in ISO automotive electronics reliability testing and related standards are as follows:
High temperature storage test temperature: 70°C, 80°C, 85°C, 300 hours
Low temperature storage test temperature: -20°C, -30°C, -40°C,300 hours
High temperature and high humidity test operation: 40℃/90%R.H. (no condensation), 300 hours
High temperature operation test temperature: 50°C, 60°C, 80°C, 85°C, 300 hours
Low temperature operation test temperature: 0°C, -20°C, -30°C, 300 hours
Temperature cycle test: -20°C (1H) ← R.T. (10 min) → 60°C (1H), cycle five times
It can be seen from this that the requirements for automotive LCD screens are very high. It must work well for more than 300 hours under extreme conditions from -40°C to 85°C.
③Prospects for the Development of Automotive LCD Screens
While the high-brightness LCD screen can work normally in extreme temperature environments, it also needs to be visible and waterproof under ultra-bright direct sunlight.
Moreover, the GPU and the display screen of the liquid crystal display module will generate heat during use, and the higher the resolution of the liquid crystal display,the greater the heat generation.
Therefore,it is also a major technical problem to develop a set of hardware products that meet the conditions of vehicles.
For these reasons,compared with the resolution of LCD screens such as mobile phones, computers,and TVs,car display screens are relatively conservative.
Now the LCD screen technology has become more and more mature,and the application of vehicle LCD screens is also increasing.The LCD screen can fully meet the changing working environment and work requirements of the car.
The application of LCD screens in automobiles has undergone a great transformation.With the development of science and technology,the development momentum of vehicle-mounted LCD screens will also be very rapid.
