In which industries are 6.5-inch LCD screens used?
6.5-inch LCD screens are widely used in four major fields: industrial and outdoor, transportation, medical and commercial equipment, as well as some consumer and intelligent terminals, due to their moderate size and ease of integration.
Different application scenarios have different requirements for screen brightness, resolution, interface, and reliability. The following table summarizes the main application directions and corresponding screen characteristics:
Application industry/scenario | Specific application examples | Core requirements and typical specifications for screens |
Industrial Control and Outdoor | Industrial control panels, outdoor testing equipment, power/telecommunications equipment | High brightness (above 700-800 cd/m ²), wide temperature range (-20~70 ℃ or even wider), high reliability, anti vibration |
Transportation | Car display, intelligent instrument panel, navigation/GPS | Wide temperature operation, high brightness (to cope with strong light), anti vibration, long lifespan. |
Medical and commercial equipment | Portable medical equipment, monitoring instruments | High reliability, wide temperature adaptability, and frequent need for touch control. Moderate resolution (such as 640x480 or 800x600). |
Consumer and Intelligent Terminals | Smartphones/communication devices, smart home interfaces, facial recognition gateways | High resolution/full screen display (e.g. 1080x2400), modern interface (e.g. MIPI), integrated touch (e.g. In Cell). |
Technical differences and selection points
The fundamental reason for the huge differences in applications of the same 6.5-inch screen lies in its different technical specifications, mainly based on the following points:
1. Interface type: determines the connection method with the main control system.
LVDS: a traditional mainstream interface in the industrial and automotive fields, stable and reliable.
MIPI: The mainstream interface for modern mobile devices (such as smartphones) and highly integrated devices, with high speed and few pins.
VGA: Some traditional industrial control devices are still in use.
2. Brightness and operating temperature: the key to distinguishing between "ordinary screens" and "industrial/outdoor screens".
The brightness of ordinary consumer screens is usually between 300-500 cd/m ², and the operating temperature range is relatively narrow.
The brightness of industrial/outdoor screens is generally above 700 cd/m ², or even higher, to ensure visibility in sunlight. Wide working temperature range (such as -30~80 ℃), suitable for harsh environments.
3. Resolution and appearance: determine the display effect and integrated form.
The standard resolution of 4:3 ratio is commonly used in industrial scenes (such as 640x480, 800x600).
Consumer and new commercial devices tend to have narrower bezels and higher resolution full screen displays (such as 20:9 ratio, 1080x2400).
How to choose
You can determine your needs based on the following directions:
If a 6.5-inch LCD screen is used for industrial control, outdoor equipment, or vehicle systems, special attention should be paid to industrial grade screens, with a primary focus on high brightness and wide temperature performance. The interface is usually selected as LVDS. For example, AUO's G065VN01 V221 series is a typical representative.
If a 6.5-inch LCD screen is used for smart terminals and commercial interactive devices (such as turnstiles and POS machines), you can pay attention to the high-resolution full screen and confirm whether touch functionality (such as In Cell capacitive screens) needs to be integrated. The interface may be primarily based on MIPI.
If a 6.5-inch LCD screen is used for portable medical or testing instruments: on the basis of ensuring reliability and wide temperature adaptability, select the appropriate resolution according to the complexity of the displayed information, and consider the convenience of touch screen operation.
If you can share the specific application scenarios of the 6.5-inch LCD screen (such as whether it is used for outdoor car navigation or factory machine control), I can provide you with more targeted analysis.
