What is the difference between a 14-pin 20x4 LCD and a 16-pin 20x4 LCD? If I want to use only 14 pins on a 16-pin 20x4 LCD, can I ignore the extra 2 pins on the 16-pin 20x4 LCD?

PS: Sorry it sounds abit confuse

Normally the two extra pins are for backlight. You can use the LCD without backlight if you choose.

For the 16-pin 20x4 LCD display diagram as below, which is pin 1? Start from the left hand side OR right hand side?

I have a 16x4 similar to your picture and pin 1 is on the left as you look at it.To be sure,follow the tracks from the backlight back to the connectors ,they will be 15&16 .
