Hi all...
I am working on a project which required 7"TFT screen. I found many types of tfts with parallel interface (16/8bit). and some TFT panels also. my question is

> if I am using a 3.3V display , is there any level translator is necessary to interface?
>>is there any available solution to plug the TFT panel directly to arduino?
>>>IS there any particular model to interface with SPI or standard UART?

anybody can suggest a best solution to getout of this riddle ? because my development time is very short.
 

If you use one of these 7" screens with the SSD1963 controller or similar, then you must use a CPU that runs on 3.3V. 5V will destroy the controller. You could perhaps use a level translator but it would be messy or slow. These 7" screens have 1MB of memory so you need a very fast CPU to update the display in a reasonable time. An Arduino at 16Mhz would be fast enough programmed in assembler but not in C. I have seen these boards designed to plug into the Arduino but they are relatively expensive. You won't see one with a serial interface as it would be to slow to be useful.
