Applications & Markets

Character Dot Matrix LCD modules offer a simple and clear method of displaying numerical information. The industry standard formats are well accepted across all market sectors.

Design engineers will normally choose the most appropriate product for the application by selecting the number of characters required for the parameters being measured by the end instrument. 
Within the Avnet Embedded standard range the preferred options are 16x1, 16x2, 20x2, 16x4, 20x4, 40x2 most of these layouts are offered with different Characters heights. Other formats are available by special request. 
If no standard option is suitable then a custom module can easily be tooled with a low NRE cost, this offers designers the choice to have the exact layout and size for the application and additional circuitry can be included.
