The screen flickering was due to input by keyboard. We have disabled the laptop keyboard during splash using the following method:

sudo nano /etc/default/grub

Replaced

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

with

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nokbd"

and updated the grub using the following command

sudo update-grub 

After reboot the display problem solved.
