LF-3011VK Application Field and Working Principle

LF-3011VK is a type of LED (Light Emitting Diode) character and numeric display modules, which is designed to offer reliable performance and a high brightness. It is usually used in high traffic, low-lighting areas or where high visibility is needed. The module itself is versatile and can be used in a variety of applications such as digital signage, message boards and other applications requiring a display.

The LF-3011VK consists of four display rows with a height of 20.3mm and a width of 46mm. Each row contains 12 character boxes and each character box has a height of 16mm and a width of 4.5mm. It can display up to 48 characters total, which allows for a wide range of messages to be created. The format of the display is the same for each of the four rows and can be set to either lower case, upper case, numbers or symbols. The module also features a built-in controller that controls the display and allows for easy programming and operation.

When it comes to the working principle of the LF-3011VK, all of the components used in the module are designed to share and amplify current. The power supply used in the module is a low voltage AC or DC supply, which is connected to a set of microprocessor-based logic circuits. These logic circuits are responsible for sending and receiving the required signals from the character display module.

The character display module consists of several parts, including an LED array, an LCD (Liquid Crystal Display) panel, and a controller board. The LED array is composed of several individual red and green LEDs, which are arranged in a specified pattern, such as a single line, a full display, or a series of symbols. The LCD panel acts as the background for the display and is responsible for displaying the colours, symbols and characters chosen. The controller board is responsible for managing the display and controlling it, and it is equipped with a set of instructions that direct it in sending and receiving the signals required to carry and display the data.

When power is applied to the module, the controller board sends a signal to the LED array, which is responsible for illuminating the LED units. The illumination from the LED units is then reflected off the LCD panel, which is responsible for displaying the chosen colours, patterns, symbols and characters. The signals sent to the LED array are controlled by the supplied logic circuits, which provide the necessary instructions for displaying the data chosen.

LF-3011VK is a great example of a reliable, versatile and high brightness LED character and numeric display module for a variety of applications. Thanks to its built-in controller, it is easily programmed and operated, allowing for quick and efficient message boards, digital signage and other applications.
