Thanks for the explanation!! Only half of the back like on the first row is turning on, what should I do?

[nguyenhongnhan]

Thank you very much. This is all my need

[ssskbslj]

Once connect, the first row of the LCD is visible as black square blocks. May I know how to check the second row of the LCD, pls.

How does this differ for a 14pin LED Board? I'm assuming to use the same first 3 and last 2 pins and will be testing this out later. Thank you and take care

سلام علیرضا. به ال سی دی که دارم درایور لحیم شده. برق رو با درایور بهش دادم و یه منفی هم به پایه وی او. درست کار میکنه. ولی وقتی از میکرو بهش دیتا میدم فقط ال ای دی نور روشن میشه. اگر از منفی میکرو به وی او یه جامپر بزنم تکست رو برای یه لحظه نشون میده ولی بعدش کل بلاک روشن میشه. مشکل از درایوره؟
