TFT LCM is a TFT LCD module, TFT means Thin Film Transistor, color display, is currently the most popular and widely used display technology. TFT LCM structure is TFT LCD glass with polarizer, FOG components and LED backlight, frame together. Techopedia Explains Thin Film Transistor Liquid Crystal Displays (TFT LCD).
Thin-film transistor liquid crystal display technology uses “field-effect” transistors, which are constructed by laminating thin films (color filters) on a glass substrate, hence the name. This technique is often used to create microprocessors. TFTs in LCDs control individual pixels in the display by setting the electric field levels across three liquid crystal capacitors in the pixel (one for each subpixel for red, green, and blue) to control the polarization of the liquid crystal display. Crystal material. The amount of polarization in the crystal determines the amount of light that reaches the color filter from the backlight. Due to this ability to directly and quickly control each pixel, TFT is also known as active matrix LCD technology.
