NHD-0420CW-AG3 is an LCD display module containing an integral backlight driver and a VGA controller board. This type of display module is an especially advantageous tool in digital circuits, and is extensively used in many industrial, consumer, commercial and medical applications. This product is small and light, with a display dimension of only 4.2" inches and a weight of less than 52 grams, making it ideal for use in devices requiring limited space and weight. As a member of NHD\'s 4.2 series, it is designed for applications requiring high display resolution. This product also offers superior image quality, starting from 176(RGB) x 220 resolution up to 640 x 480 resolution.

NHD-0420CW-AG3 belongs to the category of display modules - LCDs, OLED characters and numeric. It is a passive type display with a reflective liquid crystal, other visuals and an active backlight system driven with an AC adapter. The baseline voltage for the LCD is 3.3V, and it can support optional voltages of 5V, 12V and 24V. This product features a white LED backlight, adjustable backlight brightness and thermally-robust materials. This makes the NHD-0420CW-AG3 especially suitable for use in a wide range of applications.

The working principle behind this product is a basic matrix type liquid crystal drive. This involves one row of pixels in each column and one column of pixels in each row. The voltage on one row of the LCD matrix is selected through a row address register, while the voltage on the column of the LCD matrix is selected through the column address register. The specific pixels are driven through the row and column voltage combination applied. Then, the voltage from the backlight inverter amplifies the reaction of the LCD matrix and makes the display visible.

The NHD-0420CW-AG3 is designed for a variety of application fields. Its small size and light weight makes it suitable for applications such as portable data access systems, kitchen appliances, medical dials, industrial measuring and control equipment and wearable electronics. Its adjustable backlight brightness and wide temperature operating range makes it perfect for uses in vehicles and buses. Its superior image quality also makes it popular for applications like portable game consoles, PDAs and wireless communication devices.

NHD-0420CW-AG3 offers unparalleled performance and reliability as a display module. Its superior display resolution, small form factor and wide temperature operating range has made it one of the most widely used LCD display modules in the market. By alternating the voltage on the row and column of the LCD matrix, the NHD-0420CW-AG3 is able to get the desired display resolution and make it visible through the reaction of the LCD matrix and the voltage on the backlight inverter. This display module is capable of providing clear and sharp display to devices with limited space and weight, and is an excellent choice for applications like portable data access systems, medical dials and more.
