Display Modules - LCD, OLED, Graphic

The NHD-2.4-240320SF-CTXI#-T is a transflective, monochrome LCD display module with an epoxy coating. It is suitable for use in indoor, direct sunlight, and night viewing applications. The module utilizes an array of four columns and columns and four rows of LCD pixels that are spaced at 2.04 mm centers. The LCD pixels are transreflective and provide positive black on a transmissive yellow-green background. The display includes 2 lines of text and 16 characters. The characters are 5x7 dot matrix structure.

The NHD-2.4-240320SF-CTXI#-T uses Super Twisted Nematic (STN) technology to display the characters. STN technology requires the use of a backlight to provide sufficient illumination for a viewable picture. The module utilizes a three-layer laminate of the LCD pixels, an advanced micro-processor, and circuitry. It connects to the host computer via a 14-pin flat-flex cable. The module includes a 4-bit parallel interface and 2 power inputs.

Application

• Industrial operator control and machine display
• Instrumentation and control panels
• Medical and other analytical equipment
• Data acquisition and process control equipment
• Consumer electronics and appliances

Working Principle

The NHD-2.4-240320SF-CTXI#-T module works by applying voltage to the pixels in the LCD. When a voltage is applied, the charge in the pixel changes and a small current flows. This current vibrates the liquid in the pixel and allows light to pass through or reflect off the pixel according to the amount of current. This allows the user to see the image or text displayed by the LCD.

The module also utilizes a microprocessor to control the operation of the LCD. The microprocessor reads data from the memory and applies the appropriate voltage to each pixel. The module also includes an array of transistors and other components to enable the microprocessor to control the LCD. Additionally, the module includes an interface circuit to enable communication with the host computer.

Conclusion

The NHD-2.4-240320SF-CTXI#-T is a transflective, monochrome LCD display module with an epoxy coating. It utilizes Super Twisted Nematic (STN) technology, a three-layer laminate, an advanced micro-processor, and circuitry to display characters. The module is suitable for use in industrial operator control and machine display, instrumentation and control panels, medical and other analytical equipment, data acquisition and process control equipment, and consumer electronics and appliances.
