The connection methods of the monochrome liquid crystal display module include: conductive tape, zebra paper, metal needle, TAB, COG, etc. The following is a brief introduction:
1. Conductive adhesive strip is the most economical connection method, but its stability and conductivity are poor, and it is easy to move. It needs to be fixed with a plastic frame or an iron frame.
2. Zebra paper, the price and performance are similar to those of conductive adhesive strips. Zebra paper is also easy to short circuit, and poor or loose contact will cause the LCD screen to fail to display.
3. Metal pins, the price is more expensive, but the stability is good, the fixation is also very firm, not easy to loose, directly welded on the circuit board, the process is simple, and the use time is long.
4. TAB LCD module is more expensive and is connected by FPC flexible cable. Now few people use this method to connect, because there is a better and cheaper alternative, which is COG. TAB means to press the IC On top of the soft board.
5. COG liquid crystal module: The price is the most expensive, but in the current connection method, it is also the most advanced connection method at present, which can realize many processes that could not be realized before. COG means IC pressed on glass.
The above are the 5 connection methods of the monochrome LCD screen module introduced for you. The most common are metal pins, conductive tape, and COG. According to customer cost and product structure, choose the appropriate connection method.
