lcd module (LCD) English called Liquid Crystal Display, TFT LCD is to use TFT (Thin Film Transistor) liquid crystal display manufacturing. TFT is a thin film transistor active matrix liquid crystal display device. TFT LCD Display is designed at each pixel of a FET switch, so it is easy to achieve true color, high-resolution liquid crystal display device. LCD flat panel displays, particularly TFT-LCD, is at this stage only comprehensive catch up and surpass CRT display device in brightness, contrast, power, life, size and weight overall performance, its excellent performance, good mass production characteristics high degree of automation, low raw material costs, broad space for development, the new century will quickly become a mainstream product, it is a bright spot in the 21st century, global economic growth.
Access to information mainly through display and interactive interface with the electronic technology and electronics integrated rapid development of LCD modules in the smart instrumentation to achieve a mix of graphics and text display, man-machine dialogue to achieve the on-screen menu operation thus graphic LCD module with its small size, low power consumption, the development cycle is short, safe, reliable, flexible, etc., in the smart meter has been more widely used.
