@viveknaththulasi, Hi,
welcome to the forum! Please read How to get the best out of this forum, if you haven't done yet.
I am used to get riddles as questions by first time posters. Sometimes I can guess, but I can't guess all.
From your picture I know what e-paper you use, but it would help all readers if you post a link.
You tell that you send commands and data to the display, but you don't tell what you send.
Do you use a library, and if yes, which library? Else it comes as no surprise you only get garbage.
Did your display refresh, e.g. flicker and update the noise display?

You can do without RST (pull-up high), as long as you don't use deep sleep of the display.
You can do without BUSY, if you wait long enough for commands such as refresh or power-on to terminate.
