Nowadays, TFT display is the mainstream display technology, and tft industrial displays can be seen in various application scenarios in different countries. For example, we use mobile phones, smart watches, household appliances and automation equipment in our daily life. However, when it comes to industrial tft display, temperature range, humidity control, dust and waterproof rating, shock and vibration resistance and other factors need to be considered to ensure that the equipment works reliably and has a sufficient service life in the environment in which it is used. Therefore, it is very important to understand the requirements and design accordingly.
So as tft display need to have what characteristics?
1.Reliability
Unlike consumer displays, some industrial applications may exist corrosive chemicals, display module housing and touch surface materials have good corrosion resistance to prevent material deterioration after long-term exposure. In addition, the use of industrial applications display modules for a long time, often up to 10 years or longer, with greater stability.
2. Mechanical Testing
Mechanical testing is the process of evaluating the performance and reliability of a device or component under mechanical stress, environmental stress, and actual conditions of use. In the field of tft industrial displays, mechanical testing is used to verify that a product can work stably for a long period of time in a specific operating environment. There are various types of mechanical tests covering strength, durability, impact resistance, water resistance, etc. Industrial equipment is designed to have a long service life, so the corresponding requirements for mechanical testing such as waterproof, long standby time, outdoor high temperature, vibration and drop are also very high.
3.Brightness
In industrial applications, the brightness of the tft industrial displays is a very important indicator, which affects the readability of the device and the applicable scenarios, industrial applications need to be able to be viewed clearly and accurately in a variety of ambient light conditions. . Outdoors, high brightness industrial displays are important, and of course their brightness will be higher. Normal tft displays have a brightness of 250 to 320 cd/m2, however, outdoor displays should have a brightness of at least 1000 cd/m2 or higher.
4.Working temperature
The operating temperature of industrial displays ranges from -40°C to 85°C. However, it is common for them to operate from -20°C to 70°C. This operating temperature is sufficient for general displays, such as most indoor displays, and everyday industrial automation equipment. For equipment used in harsh environments, industrial displays can operate from -40°C to 85°C or higher. For example, heavy industrial scenarios such as steelmaking and petrochemical plants.
