Comment contrôler le contraste du module ?

En général, le contraste est contrôlé par la tension. La source d'alimentation a VDD, GND, VO, VEE et VO est la tension essentielle qui contrôle le contraste. Nous recommandons généralement à nos clients d'utiliser un VR de 20K et de le placer entre VDD et GND, ou entre VDD et VEE (comme indiqué dans la figure ci-dessous). Vo est la tension différentielle.

 
Vo est la tension différentielle entre VDD et GND. Lorsque vous utilisez VEE, VO est la tension différentielle entre VDD et VEE.
