LCD DISPLAY COMBINE WITH 7 SEGMENT

How to combine the LCD display with 7Segment using arduino mega?

Not sure if there is enough pins to mutiplex, but if not I suggest using IIC or SPI backpacks from adafruit or similar.

Up to nine digits of LED display of seven segments can be handled using the charlieplexing technique with nine Arduino pins. Anyway it is still a bummer to control the led by switching.
