Introduction

NHD-3.5-320240MB-ASXN-CTP is a display module from Newhaven Display International (NHD), which has more than two decades of industry experience in cutting-edge display technologies. It is a 3.5” LCD display with a 320 x 240 resolution. The NHD-3.5-320240MB-ASXN-CTP has an industry-exclusive glass-eyed TFT that is built with active matrix technology and touch panel support. The touch panel support further improves user interaction and operation. It comes with a standard 40 pin RGB interface to connect to a wide range of microcontrollers.

Application Fields

The NHD-3.5-320240MB-ASXN-CTP is useful for a variety of applications. Its large size and higher resolution make it ideal for many types of small industrial and consumer grade products. Its features, such as the glass-based TFT, active matrix and touch panel, make it suitable for more sophisticated applications. Furthermore, its 40-pin RGB interface is compatible with many MCUs and controller boards, giving designers a great deal of freedom in application selection. Common examples include medical equipment and portable devices, as well as home appliance, POS and kiosk systems.

Working Principle

The NHD-3.5-320240MB-ASXN-CTP has a glass-based TFT (Thin Film Transistor) display. Each pixel in the display is composed of three transistors and three capacitors. The transistors act as a switch to turn each pixel on and off, while the capacitors control the voltage of each pixel. The touch panel support further enhances the operation of the NHD-3.5-320240MB-ASXN-CTP by allowing users to easily interact with the display. It works by detecting a user’s finger, or other capacitive materials, which then triggers an event based on the user’s input.

Conclusion

The NHD-3.5-320240MB-ASXN-CTP is an impressive display module from Newhaven Display International. Its features include a glass-based TFT, active matrix, touch panel and 40-pin RGB interface. It is suitable for a wide range of applications, from industrial to consumer, medical to home appliance. Its working principle is based on the use of transistors and capacitors, which act as switches and voltage controllers, respectively. Finally, the touch panel support enables users to interact with the display in a more efficient way.
