LK204-25-V-E Application Field and Working Principle

The LK204-25-V-E is a display module that largely falls under the umbrella of LCD, OLED Character, and Numeric displays. It utilizes a Character Display, otherwise known as a "VFD" or Vacuum Fluorescent Display, with a size of 2 lines, 20 characters per line and a character size of 2 x 5 dots. This type of display is semi-transparent and is able to display alphanumeric characters and special symbols, as well as graphics. Additionally, the display is capable of displaying international language characters such as English, French, German, Italian and Spanish. The module operates using a single power input system and can be used in several temperature ranges due to its temperature protection technology. The LK204-25-V-E display module also features 24 different control functions, as well as 9 bright display levels, allowing for greater control of the display over traditional LCD and OLED displays.The main application fields of the LK204-25-V-E display module include automotive displays, home appliances, industrial computers, and digital signage products. The display module is particularly suited for use in instrument clusters, headsets, and video game systems that require the ability to display multilingual characters. In terms of its working principle, the LK204-25-V-E display module utilizes a technology known as Vacuum Fluorescent Display (VFD). The VFD technology involves the use of a “cold cathode” to create a vacuum in a closed space. A phosphor coating (which lights up) is then added to the interior of the vacuum. When an electron beam strikes the phosphor, the phosphor emits light, thus creating a bright and visible display on the LCD and OLED displays. In addition to the phosphor, the display module also comprises of a discharge and resistor assembly, anodes, electrodes, and control regulation.Ultimately, the LK204-25-V-E display module is an efficient and reliable choice for a variety of applications. It is capable of displaying international language characters and offering great control to users. Furthermore, its temperature protection technology and range of control functions make it an ideal choice for many different types of devices.
