Simplest solution > TFT screen or seven segment?

I need to display around 24 numbers on a display with a single Arduino board.
The conditions are:

  • cheaper
  • the font size to be 20% of the screen height.

Which is the simplest solution, a 10" TFT screen, or is there a solution for 7-segments?

The largest 7-segment I have seen are 4" tall. $40(?) for 2 digits.

You are not very clear about what you want. You want to display display 24 numbers side by side? Will they fit.

There are libraries for TFT displays but not for every size, using 7 segment displays is easy.

I've been confusing.

I have 24 digits to display, but not all on the same line, of course.

The board I'm using has few pins available (10-15).
So what are my options?
Use a tft screen, are there any modules which simplify working with many 7-segment modules, or I would need to add another board in scheme?

Use 3 MAX7219 and drive 8 digits with each one? Only need 3 control pins.
Use an I2C or Serial or SPI interfaced display, just 2 or 3 pins needed.

Thanks, that’s a good solution.

What if I have 3 digits? I need to display percentage 0-100.
What would be an efficient solution?

MAX7219 can be set to drive just digits also.
That link is blocked for me, is it a 3-digit common cathode display?

That was a 8-digit cathode display module which includes the digits and max7219 too.

Probably I can remove one on the two digit blocks, right?

They do appear to be socketed.
