It is an 176x220 screen with an ILI9225 controller that uses a SPI interface.
The pin-out is designed to fit on the Power and Analog headers of a Uno. CS on A4 and VCC on 5V.
RS just means Register-Select. Some people call it DC for Data-Command. Occasionally you will see it called A0.
There are libraries out there for driving your display when plugged into the Arduino A0-A4 pins.
They bit-bang SPI. The U2 buffer chip does the level-shifting from your 5V Uno/Mega.
Unfortunately the board does not provide a MISO line. So you can not read the display.
Of course you could ignore the convenient pluggability and hand-wire everything with jumper cables. e.g. to use the 3x2 hardware SPI header.
These boards have various controllers fitted. If you have a 1.8" display it is likely to be 160x128 pixels with a ST7735 controller (I have one of those with an identical PCB as in the posted image).
The 2.2" variant tends to be a 200x176 with a ILI9225.
The board should work with the built in IDE TFT library if you wire the display up as follows (this assumes you are using an UNO):
VCC => UNO 5V
GNC => UNO GND (aka 0V)
CLK => UNO pin 13
SDA => UNO pin 11
RS (also known as DC) => UNO pin 9
RST => UNO pin 8
CS => UNO pin 10
NC means "No connect" so those pins do not need to be wired up as they do nothing! It might look like one PCB track goes to an NC pin but the track path takes it to another adjacent pin.
The good news is that you do not need a logic level converter for that display, so it was a good choice.
These connections should work with any TFT Arduino example, such as Examples > TFT > Arduino > TFTDisplayText
If the examples do not work or there are some display problems the post back.
If the examples do work then post back anyway so that other forum readers know too.

can you give me the code
i was trying evry code its still didn't work
Seriously? john917 posted two years ago and never since. Additionally you are asking for something, offering nothing. After reading the how to use this forum post at the top, please start a new thread, show us what you have and what you are trying to do and you will get some help.
