The Connection Type of LCD can be mainly divided into Conductive Rubber Strip Connection, Metal Pin Connection, and Zebra Connection.
1. Conductive Rubber Strip Connection
It is flexible, can be assembled and disassembled rapidly, and needs no welding. Besides, it has a better shock resistance.
2. Metal PIN Connection
Metal PIN connection can be soldered directly on the printed circuit board.
PIN is the most commonly used connection for LCD. I am often asked to answer one question. Can we make the pitch between two PINs 1.0 mm? Of course, we can as long as you pay for the extra cost. There are 4 common used types of pitches: 1.27 mm, 1.5 mm, 2.0 mm and 2.54 mm. The widths of PIN are 0.635 mm, 0.75 m,1.0 mm and 1.27 mm. If you can order 50 thousand each buy, we can make the custom PIN (even bent PIN) and the custom pitch for you and there is no extra cost.
3. Zebra Connection
A printed circuit board and an LCD are connected by flexible zebra paper, which adopts heat sealing processing or soldering processing and can be used in all kinds of harsh environments.
4. The comparison of three connections
|Connection type||Connected with LCD screen||Connected with PCB||Pitch gap|
|Conductive strip connection||Conductive strip connected with isolated rubber||Mechanical pressure||Min 0.3 mm|
|Metal PIN connection||Metal PINs are soldered in the LCD steps||Soldering||1.27, 1.5, 2.0, 2.54 mm|
|Zebra connection||Conductive thin film||Heat seal, soldering or mechanical pressure||Heat seal: min 0.4 soldering type: min 0.8|
