The difference between TFT module and lcd module

Understanding the various characteristics of the TFT Llcd module technology can better match the display and interface with the current application. As people are increasingly eager to have a more user-friendly graphical interface, more and more companies are asking engineers to design TFT modules and LCD module products into their own products.

In the process of selecting a display, consider whether you need a TFT module or an LCD module. The first thing to remember: color increases costs. You can save a lot of money by using the monochrome graphic LCD module to design. They are inexpensive, relatively easy to connect and control, and are readily available. Monochrome displays require less hardware overhead and complex software. The management of one color per pixel is easier than the management of three colors per pixel (red, green, blue).

According to different design criteria, LCD module panels may have many advantages over TFT module panels, such as outdoor brightness and overall color brightness. When deciding between the TFT module panel and the LCD module panel, don't forget the refresh speed and viewing angle. The TFT module can provide a viewing angle close to 180°, and although the LCD module is constantly improving, it generally only provides a viewing angle of 70° to 80°. In addition, the TFT module can display full motion video and graphics, while the lcd module will start to blur when the image moves faster than 8-15 frames per second (the number of frames depends on the manufacturer).

But don't give up choosing LCD module panel because of these factors. When looking for the perfect display, various options should be explored. For example, the current application may require an outdoor handheld system, which needs to have good readability in the sun. At this time, you may find that the small-size TFT Llcd module and LCD module work well in this application, but the TFT Llcd module may have a better viewing angle, and the color of the LCD module panel is better.

When choosing a TFT Llcd module , the first thing to consider is the size. For the LCD module, what needs to be measured is the length and width of the display, while the measurement of the TFT module panel is just like the measurement of the crt display: the measurement is the diagonal length.
