NHD-320240WX-GTFH-V#I Application Field and Working Principle

The NHD-320240WX-GTFH-V#I is an intelligent STN display module that is designed as a cost-effective solution for monochromatic LCD graphic displays. This display module is most commonly used for handheld device applications such as electronic meters, handheld test or measuring equipment, and point-of-sale (POS) terminals. The display module is equipped with a STN panel with a resolution of 320 x 240 and a dot size of 0.53 x 0.53 mm.

The display module is comprised of three components: the LCD panel, the circuit board, and the backlight. The LCD panel is composed of a monochromatic LCD display covered by a glass shield to protect the display from dust and shock damage. The backlight is used to illuminate the display so that it is visible under bright lighting conditions. The circuit board includes an integrated controller and interfaces, such as the backlight power signal, the power signal, and the interface signals.

The NHD-320240WX-GTFH-V#I consists of an LCD driver IC and a STN controller IC. The STN controller IC provides the display with a triple row-column inversion capability which enables the display to display inverted colors without having to change the display driver IC. The STN controller IC is programmed to store and display display data in either text or graphic format. The display also has an 8KB RAM that can store up to 1024 bytes of display data. The backlight power is provided by a separate power source and can be adjusted in software.

The NHD-320240WX-GTFH-V#I supports a wide variety of display functions such as font size selection, font style selection, and inverting the display. The display functions are controlled by a microcontroller or a host CPU via an 8-pin connector. The connector supplies power and the control signals for the display through two 8-pin headers. The display can be operated in either 8-bit or 16-bit mode, depending on the application. The display module also features several built-in features such as a contrast function, a voltage regulator, a backlight dimmer, and a sleep feature.

The NHD-320240WX-GTFH-V#I display module is an ideal choice for those who require an economical and versatile display solution. It offers excellent readability and display capabilities while still providing a cost-effective solution. With its built-in features, the display can be used in a variety of applications, such as handheld device applications, medical instrumentation, and POS terminals.
