Dear all,
I need some suggestion on selecting display and Arduino based development board for my application. I am planning to make product which uses graphical display with key
Key operation:
Increment
Decrements
Menu selection
STOP operation
Control output:
Relay
Stepper motor 2 nos
Heater coils
Sensor:
temperature sensor
Limit sensors
Display :
Should be display all parameter
kindly let me know do above thing which development board hold good.

Incoherent, but it does sound like the sort of thing as Mega can do. It rather depends on the size of the display.
Just a suggestion: Fix your subject line in your first post.
It's serious. If you appear not to be able to type, people may be less disposed to help you - since typing accurately is an absolute prerequisite for computer coding. 
ENCODER MENU
could this would be one way ?

the generic way to start is for you to make a few lists.
#1) list every digital input
#2) list every digital output
#3) list every analog input
#4) list every analog output
then, get a data sheet for every I/O point and make sure you have all the correct power and voltages, etc.
in some cases, you need only 1 pin for many sensors, for example the DS18B20 temperature sensor.
get this started and as you get an exact pin count and voltages, the correct microcontroller almost picks itself.
