what is type of this RoHS LCD ( Any datasheet)?
The datasheet indicates that this display -- like most small LCD character displays -- implements an interface compatible with the Hitachi HD44780 controller. There are two extra pins on this part (17 and 18), but they can both be safely left disconnected.

This interface is implemented by the Arduino LiquidCrystal library.

Note that RoHS is not a brand name -- it's an inspection mark, indicating that the board (probably) meets the European Restriction of Hazardous Substances directive by not containing any lead, mercury, cadmium, or certain other toxins.
