MCU in LED Display Board

Most of the ones I saw used the 89C51 or 89S51 or PIC16F72 or PIC16F877.
But, why are you asking about the most popular one?
If you're going to make one, you can use a microcontroller of your choice if it just has enough IO pins.
So, you can make one with PIC16, PIC18, 8051, AVR, etc.
 

I am already using 16F72, but confused that whether it is a good choice for production of LED Display Board at large scale.
 

I agree with what Tahmid says.

I think it would depend on your company's negotiating power with its suppliers. Given similar levels of functionality and reliability, what you need to do is minimise cost. Any small MCU is simple enough to develop with, so development costs should be no different and it boils down to finding the cheapest available parts from a supplier in your region.

Answer on this question is not easy, and depends on many things.

Phrase "Most popular MCU" is questionable, also as "professionals".

All depends what kind of LED Display project is included, maybe you need lots of pins on uC.
What is price of uC ? What generation and manufacturing status is for that particular uC? ....

I think PIC16F877 is old and unduly expensive as PIC16F84, better look in PIC18F45K22 direction and other newer uC.
