Application fields

NHD-320240WG-DTMI-VZ# display modules are mainly used in automotive and medical applications, such as vehicle device displays and point-of-care medical device displays. NHD-320240WG-DTMI-VZ# modules are also suitable for industrial and consumer applications, including portable electronic devices such as handheld testers, equipment controllers, thermometers, and weight scales.

Technical Overview

The NHD-320240WG-DTMI-VZ# module is composed of an active TFT LCD panel, a driver IC, and an interface board. The active TFT LCD panel features 320-by-240 resolution, a maximum contrast ratio of 500:1, a minimum brightness of 200 cd/m2, a response time of 6ms, and a wide viewing angle of up to 160°. The driver IC supports both 3.3V and 5V operation, and provides two-pixel data signals, two-line control signals, two-for-one address signals, and two-for-one idle signals. The interface board provides two sets of FPC (flat cable) connectors, which enables easy connection to external systems.

Working Principle

The working principle of the NHD-320240WG-DTMI-VZ# display module is based on the TFT LCD technology. When an electrical signal is applied to the gate circuit of the active layer, it will create a transverse electric field across the active layer, allowing the charged particles on the active layer to move freely. This movement creates a voltage difference in the horizontal and vertical directions, generating a localized electric field. When the electric field is combined with the electric field generated by the gate circuit, the color of the pixels will appear on the display.

Conclusion

NHD-320240WG-DTMI-VZ# display modules are a type of LCD, OLED or Graphic module, specifically, a TFT Thin Film Transistor type of LCD module. These modules are characterized by their low power consumption, wide viewing angle and high resolution. They are widely used in vehicle device displays, point-of-care medical devices, and portable electronic devices, and they work by creating an electric field across the active layer, allowing the charged particles on the active layer to move freely in order to generate a voltage difference in the horizontal and vertical directions.
