I have TFT 320QVT 9341 tuch screen but I haven't a Arduino display shield. Can't i connect directly touch screen to the Arduino mega 2560 ?
Touch screen - 16 bit
3.3V
No
I'm not sure what display you are referring to, but I can write images from and SD card to mine--
Here's what I have and a tutorial.

Well I am. It is one of these :-
Refer to my previous answer.
If a simple answer to a simple question is not clear enough, let's have a complicated answer then....
This standard 40 pin TFT module in common with most other 40 pin TFT modules is 3.3V, designed to run at 3.3V. The Mega is a 5V device, as such, voltage translation is required on almost all of the pins.
Can I connect this directly to my Mega? NO!

thank you for your answer.
I am trying 5V Arduino outs reduce to 3.3V using resistors (Voltage Dividers) but output voltage is 3.28V , Is this process method right?
If any method available for make sure my display work fine?
