The LK162A-4T-USB-FGW Display Module is a versatile, low-power and cost-effective display solution that can be used for a wide range of applications. It is a four-line character and numeric LCD module that can be interfaced with USB, TTL, and RS-232 interface. The module provides superior contrast and wider viewing angle than conventional LCDs, allowing for clear text display and excellent results even in bright environments. It is available in 13x43x7mm and a wide range of panel sizes.

The LK162A-4T-USB-FGW character and numeric display modules utilize a unique low-power technology to reduce power consumption and extend battery life. It can operate as low as 0.15 mW and can be powered directly by a USB bus or a 5V DC supply. This module is also available in versions that are compatible with 5V, 3V, and 2.23V operation.

The key features of the LK162A-4T-USB-FGW character and numeric display module include its low consumption, bright backlight, wide viewing angles, wide operating temperature range, and high contrast. It also provides a wide range of options for display modes and characters, and is easy to use with a built-in controller.

The working principle of the LK162A-4T-USB-FGW display module centers around the use of a Liquid Crystal Display (LCD). An LCD is a simple device that consists of two pieces of polarized material, usually made of glass or plastic, sandwiched together and held together by a sealing material. Between the two pieces is a liquid crystal material, which changes its optical properties when a voltage is applied. By varying the voltage, the display’s contents can be controlled.

In a Focused Grid Wiring (FGW) arrangement, the LK162A-4T-USB-FGW display module is composed of two glass substrates sandwiched together with a tiny gap between them. The two inner surfaces of the sandwich contain a pattern of electrode segments which form the LCD matrix. When a voltage is applied to one segment, the adjacent segment is either switched off or on, depending upon the voltage value. By varying the voltage, the contrast and brightness of the display can be varied.

In addition to the FGW structure, the LK162A-4T-USB-FGW display module also uses an integrated controller. This controller is responsible for controlling the display on/off, screen brightness, and other display parameters. The controller reads the data from the USB, TTL, or RS-232 interface and produces the necessary control signals for the LCD. This eliminates the need for a separate driver or controller when connecting the display module to a microcontroller.

The LK162A-4T-USB-FGW display module is used in a variety of applications such as data logging, menu navigation, instrument readouts, process control, digital signage, and embedded system control panels. Its low power consumption and wide range of features make it an ideal choice for a wide range of applications. The module is available in a range of colors and sizes, and is an excellent choice for those looking for an easy to use, low-power display solution.
