So i have this LCD screen: http://www.hantronix.com/down/700L-1.pdf and i'm wondering if i can use it with arduino to display something.
I'd also like to know how can i connect the connector to arduino.
I doubt it. That display needs constant refreshing, this is done with something like a graphics controller chip or a processor with a lot more memory and speed than the arduino.
It has a resolution of 800 X 480 and 6 bits per pixel for each of Red, green and blue, which means to cover this you need a memory of:-
800 * 480 * 6 * 3 / 8 = 843.75 K bytes of memory. Given that an arduino has 2K you can see it is nowhere going to fit.
Oh well, i try some other display then. Thanks for the answer!
