I've 2.8" TFT SPI Module from mcuFriend, it is said that the TFT based on ILI9341 controller.
I've attached photo's for front, back and connection with arduino. I need help to get it work correctly.
1- What library should I use? and Do I have to change any parameters inside my code to get it work?
2- How do I verify the type of controller chip?
3- The connection as it appears on the photo, Is it correct?
What is the part number(s) printed on the integrated circuit?
Yes, it looks as if you can connect the signals like that. (when we know your i.c.)
You still need a 3.3V supply
I would feel a lot happier with a schematic. I have never seen a display like this.

Edit. Ah-ha. It might pick up power from the 3x2 header intended for the 16U2 on a Uno R3
This will be no good on a Chinese clone that uses a CH340.
I've attached screen shots for serial monitor outputs when running graphictest_kbv and LCD_ID_readreg examples from MCUFRIEND_kbv library
Those programs are for a Parallel ILI9341.
You should use Adafruit_ILI9341 Library or similar SPI library. The CD4050 will make it safe with a 5V Uno.
Use full fat constructor i.e. with the TFT_RST pin.
Let us know how you get on.
David.
