You could use a BCD decoder/driver chip such as the MX7219 or HCF4511 chip* or write the decoding algorythm yourself by consulting the table posted above by xfpd. The number/letter combinations indicate which segments light up for the combination of pins 1-4 and common pins COM1 to COM4 (pins 5-8).

*Sorry, those are for LED displays not LCD.

what else can you suggest that is similar to this screen but easier to use

This device operates the same as any 2-digit, 7seg LED.

I can't find 2 digit versions of this, but this should be easier to use. There is an Arduino library for it.
