OLED vs LCD screen physical size comparison:

I am certain I will need a new brain to use OLED but I'm loving the yellow.

The OLED has no color, just black background and one foreground color. What I find love about this OLED is how black the background is, and how fast it works in cold weather, unlike the LCD type which gets sluggish in cold weather. The OLED is rated for -40C or -40F.

The screen is now 4 lines by 20 characters, comparing to the LCD which was 2 lines by 16 characters. Maybe in 7-10 days I'll be ready to sell OLED options, I'm just busy at the moment fulfilling orders to 3SX.

Okay let me know when you're ready.

By the way do you have any more screenshots of how the information is presented on the 4x20 display?

Sorry, I didn't take any other screen shots. I've combined screens into 4 lines where I could. I haven't modified the main menu to 4 lines yet -- I plan to display external sensor data on there, as I think that is what people would want.

More information per screen so there is less need for scrolling would be awesome. Like both front and rear trims on the same screen and all 4 senors on another screen.

Exactly, and by the way, what you've suggested I've already combined also.

That sounds great!

Would it be possible to replace the power regulator in older units with at beefier one to avoid having a separate power cable for the OLED display?

The good news is the linear voltage regulator inside your LCDBC unit can provide the necessary power, it's just a question whether or not the heat sink is adequate.

[Unlogic]

Is this the dual regulator version that supports the OLED display or should I be looking for a bigger heat sink?

[BlackStealth]

Your purple boxed LCDBC shows 1 voltage regulator with a heatsink, and 1 power transistor for boost solenoid.

I already have a solution for older LCDBC units. Because the OLED requires an adapter to convert 20 pins to a 4 pin wire harness, this is a good place to include a low profile voltage regulator -- problem solved.
