I want a 6 inch graphic LCD that has a driver installed on it and has thin flat cable .because I want to connect it to hinge for rotating.
can you help me?
At exactly 6-inch (diagonal measurement), we have part numbers 2632-E60RA-I-MW560-N-ND (non-touch) and 2632-E60RA-I-MW480-C-ND (capacitive touch) which might work for you. The interface and controller type is listed on those product pages.
Use the datasheet links to learn more about the features for each product. I did see that a driver circuit is included in these, for example.
