What is the distance between the pins of the LCD screen?

LCD LCD is one of the most common LCD screens in our lives, today RINA TECH to introduce is about the distance between its pins and glass, let's take a brief look at it.

  The first point, segment LCD pin location if close to the most corners, according to the tension, the tip of the pin is the smallest, if the size of the board and the pin at a very tight match, the engineer will have to put the LCD LCD into the PCB will be very capacious to cause collapse, or the process of welding due to high temperature solder heating will also cause the phenomenon of collapse.

  The second point, the glass in fact, and other items like thermal expansion and contraction at different temperatures, if the pin is at the most edge of the position, it will cause strain, although generally not visible, but the pin and the glass will certainly produce loosening between the conductive adhesive conductive area will be reduced, resulting in a larger resistance.

  In the case of unchanged voltage, the resistance will cause the current to pull, but the circuit can provide a limited current, it will cause the stroke we know the word light, or cause a lack of painting phenomenon occurs.

  LCD LCD pins and glass if not maintain a certain distance between the consequences of the above
