PWM multiple 7-segment LEDs

You should also look at HT16K33 , that can read in switches and buttons too
ditto for
tm1637 and 1638

Alibaba is a game-changer for little people like me.

I'm talking with a supplier for 15 inch displays 4K UHD 3840X2160; just the screen and the controller board (I'm using Acer 19 inch displays at only 1366x768 myself).

I already resized all my gauges to make sure they can fit in the space. I end up with high quality graphics, low weight, lower cost, and a LOT less work.




That's all the gauges practically identical to the game, and this screen runs on VGA or HDMI. I just hope it's better quality than the ones I already got from AliExpress.

Impressive isn't it?

This is why I went with the 7-segment display route. I had bought 2 LCDs from AliExpress and was really disappointed by the quality. The viewing angle was just too narrow, and the backlight was overly bright, even with setting turned down to zero (my decade-old Acer x183H in the background is still better).




This pic is from the manufacturer using my image, on her PC in the back, and the display in the front.




It's not a photoshop; she also sent me video. They sell these to laptop manufacturers.

Using 7-segment displays brings its own challenges; more complicated, lots of parts for solder, lots of circuits to install. I didn't get a final price on the 15" display, but it's most likely going to be a justified expense. And it's going to look freaking awesome once assembled.

There's another advantage; the next plane on my list is the Cessna 172 and it uses 2 displays side-by-side:

I haven't done any tests yet, but I should be able to place both of those on the 15" screen.

Definitely the LCD is the way to go!

I would not bother with any LEDs display. Maybe only for the buttons or pots. Or is this possible to be done with touch displays too?

It's always possible to do touch, but I like the feel of mechanical devices. 🙂

Me too!
