LCD instead of LED, how?

bascom 7 segment 4511

Hi!
I came across a schematics which I would like to build, but the original design uses LED displays (3 pcs - 7-segment, 13mm), not LCD what I would prefer. So, my question is: how can I alter the circuit so it can drive the LCD display (3½ or 2½ 7-segment digits). Thanx!
Here's the drawing:

4511 is a CMOS 7-segment driver, so it drives 7-segment displays... With this circuit is hard to do what you want to do, cause you would have to add lots of logic to drive your LCD... I suggest you to take a microcontroller and make new LCD drive... You can find lots about it on google

if you want to use 16x2 lcd then you have to use microcontroller.

You may use 8051 microcontroller.

you can use atmega 16 or 32 and download bascom compiler , there it's easy to use , contact me if you want to know more.

There are 7-segment LCDs available, but u need to use different driver IC for it like 4055B / 4066B
