The LCD-S401M16KF/W3 display module is a four-digit (4.5" wide) character display with LED backlight and white characters. The display area is 8 columns by 8 rows, with an active viewing area of 5.62" x 7.62". The display has a total of four lines, each line having a resolution of 40x20 pixels. The LCD display module comes in various colors including blue, green, yellow, black, and white.

The input signals for the LCD-S401M16KF/W3 display module include power source and control signals. The input signals are either single-ended (TTL) or differential (RS-422/RS-485) compatible. The input signals vary according to the control signal, with each line of the display module having its own input signal. The control signals are used to control the LCD display module, such as contrast, brightness, backlight on and off, contrast adjustment, etc.

The LCD-S401M16KF/W3 display module uses backlight with an LED system. The LED is connected to a constant current circuit and one AC power. The LED power is controlled by two transistors and the AC voltage, so that the required control signal can be sent to the control circuit for the brightness setting of the backlight. The power supply for the LCD display module is output at 3-5V and the input signal is 5V TTL or 4-20mA.

The LCD-S401M16KF/W3 display module is mainly used for industrial, navigation and navigation-related displays, such as GPS navigation displays, automotive navigation applications, point of sale displays, and marine navigation. The module also has a wide range of applications in telephone, audio, video and other consumer electronics products.

The working principle of the LCD-S401M16KF/W3 display module is based on the voltage control of the electrodes and liquid crystals in the display. Voltage is applied to the electrodes and the liquid crystals will be rotated by the force of the applied electric field. The angle at which the liquid crystals are rotated will determine the level of light intensity entering the display. The angle and intensity of light entering the display can be adjusted by varying the voltage applied to the electrodes. This principle is used to create digital and analog displays. For example, the display can be used to display numbers, symbols or pictures with pixels, and the voltage control can be used to control the brightness of each pixel.

The LCD-S401M16KF/W3 display module is a reliable, cost-effective and power efficient solution for a wide range of industrial and consumer applications. The module is easy to integrate into existing systems, and its visual quality makes it ideal for a variety of applications. With its wide range of applications, the module has become a popular choice for many industries.
