It is ideal for industrial control applications such as robotics, automation, motion control systems and control panels. It can also be used in medical equipment, medical carts, vital signs monitoring systems, blood pressure monitoring. In consumer products such as home appliances, point of sale (POS) displays, personal entertainment systems, gaming machines, and toys.

Working Principle

The NHD-0224WH-ATDI-JT# works on the principle of LCD panel, LED backlight and I2C digital interface. The LCD panel is composed of a thin, transparent layer that is placed between two polarized filters. The LED backlight is a source of light that is used to illuminate the LCD panel. This backlight uses current to light up, and this current is supplied by the I2C digital interface. The I2C digital interface is a communication protocol which transmits data over two wires, the SDA and SCL, and allows the user to control the backlight and control the logic voltage levels of the LCD panel. The I2C digital interface is connected to a PIC microcontroller which stores the data and controls the logic voltage levels of the LCD panel. The data is then read from the PIC microcontroller and displayed on the LCD panel.

Advantages

• It consumes very low power.
• It has relatively low price.
• It provides a good contrast and viewing angle.
• It is easy to use, with a variety of interfaces.
• It is compatible with several operating voltage.
• It is reliable and durable.

Disadvantages

• It has a slow response time.
• It has limited resolution.
• The I2C bus requires extra material and power.
• It may be difficult to set up.
• It cannot handle complex graphics.

Conclusion

NHD-0224WH-ATDI-JT# is an LCD, OLED Character and Numeric Display Module used in a wide range of applications in industrial, medical, and consumer fields. It works on the principle of LCD panel, LED backlight and I2C digital interface. It provides excellent contrast ratio, viewing angle and low power consumption.
