What is LCM LCD?


LCM (LCD Module) is an LCD display module and a liquid crystal module. It refers to a component that assembles a liquid crystal display device, a connector, a peripheral circuit for controlling and driving, a PCB circuit board, a backlight, and a structural member.


Common terminology for the manufacturing process of liquid crystal modules (LCM)


TFT-----Thin Film Transistor: Thin Film Transistor


CF-------Color Filter: Color Filter


LCD-----Liquid Crystal Display: LCD


TAB-----Tape Automatic Bonding: Loaded Package IC


PCB-----Printed Circuit Board: Printed Circuit Board


ACF-----Anisotropic ConductiveFilm: anisotropic conductive film


B/L------Back Light: backlight module


Assy---Assembly: Assembly


B/Z------Bazel: iron frame


Bonding: Pressing


Three stages of "front, middle and back" manufactured by TFT-LCD


As shown in the above figure, the latter module process is mainly the integration of the driving IC of the liquid crystal substrate and the printed circuit board. This part can transmit the display signal received from the main control circuit to the driving IC to drive the liquid crystal molecules to rotate and display the image. In addition, the backlight portion is integrated with the liquid crystal substrate at this point, and the complete liquid crystal panel is completed.
