LCD Module's Interfaces & Selection
Topway TFT LCD module and graphic LCD display module come with different interfaces and screen sizes, are suitable for diverse types of applications.
Topway’s Smart TFT LCD module is designed for industry use, incorporated with RS232/RS485 interface. Smart LCD module can co-operate with external system, work as “slave” or “master”. The use of Smart TFT LCD module greatly reduces demand from main board. Thus shrinks hardware cost and technical barrier. Because all display objects are pre-stored in Smart TFT LCD, screen can be quickly updated and refreshed.
Normally, a compact device or simplified main board provides only MCU bus to external system. We recommend Topway LCD Module with MCU interface. Engineers can pick either 8 bits or 16 bits bus for their products.
In industry field, a device’s screen and control board could be far apart, because of different reasons. Topway’s LVDS/EDP TFT LCD modules are designed for this. It enables protecting main board yet showing display from a distant.
When using PC as industry control device, VGA or HDMI is the default interface. Joining force with Topway VGA/HDMI LCD module, this solution provides satisfactory display result and improved product reliability & flexibility.
Newer generation MCU has embedded TFT controller. When device main broad and display module is relatively closed. Using Topway LCD module with RGB interface(or TTL)，can achieve cost saving and satisfy industry application’s requirement.
Bandwidth Matters
Display components stretch the limitations of bandwidth. For perspective, below is a typical 7" TFT LCD display's calculation.
Conclusion
Choosing the right display for your application requires more than knowing what it needs to look like and what the optical environment is.
Important factors:
Knowing how to connect the display to the electronic system
Choosing the right interface to the display
Key parameters:
The amount of data
The refresh rate
The number of colors of the GUI
Don't forget to future proof the interface when your marketing department wants a new GUI for the next software update.
