COG is an LCM module manufacturing process adapted to the times
Because the structure of COG module is relatively simple, stable and durable, with the gradual development of society, more and more people begin to use cog LCD.
LCM (liquid crystal display module) is a component that assembles LCD devices, IC, connectors, control driving circuit, backlight, PCB circuit board and structural parts. LCD devices, especially dot matrix LCD devices, have many and dense leads, which is very inconvenient for users to use. In order to improve the integration of LCD devices, LCD manufacturers generally make dot matrix LCD devices and drivers into LCM modules for sale, which not only improves the added value of products. Therefore, the continuous improvement and perfection of the manufacturing technology and manufacturing process of LCM module has become a powerful means for manufacturers to explore the LCD display market. The connection method of the external lead on the LCM module (i.e. the conductive electrode lead on the LCD screen) can be classified as follows according to the connection mode between the LCD electrode and the driving circuit:
(1) Metal pin connection;
(2) Conductive rubber connection;
(3) Direct integrated connection (COG);
(4) Hot pressed adhesive strip connection.
Cog's product structure is very simple, that is, IC and lead are added to an LCD display screen, and then ACF (an anisotropic conductive adhesive) is used to bond the IC directly to the LCD screen through hot pressing. The whole module after bonding needs to be connected with the PCB board through FPC (flexible printed circuit board) or metal pins. LCD, ACF and driver IC are the three key components of COG screen.
