LCD to LED Display?

Hello.

Here is a nice one for you guys to chew on. I have some TC820 chips from Microchip. It is a Voltage meter/Frequency meter chip and has a built-in 3 3/4 digit LCD driver. I discovered that 7-segment LCD displays are expensive and hard to find. LED displays, on the other hand, are cheap and common. My question is this: Does anyone know how to drive an LED display using an LCD driver? If it is possible, what additional circutry is required? Thanks in advance to all who help.
 

LCD to LED Display?

wht is the need of LCD driver for some 7segment display. Use 7segment display with its driver(7447,46).

Re: LCD to LED Display?

I want to use the TC820 chip (which has a built-in LCD driver) to drive an LED display instead of an LCD.

i think tht chip have parallel I/O pins, you just use them.

It does not, otherwise I would not be writing this post. (Unless you see something in the datasheet that I do not.)
 

Re: LCD to LED Display?

i always thought to drive a LED, one would use current source... LCD, voltage source....

Electronicus, Thanks for your help. That looks like it may help, but there is one small problem: I only speak english. Is there an English version of that page?

Added after 9 minutes:

Here is the datasheet for the TC820. Maybe it will help.
