Raspiblitz: screen burning?

[cedricwalter]

Did you notice any screen burning? my PI is synchronizing since 2 days now. Is there a way to stop the screen and only make it react when touched?

Thanks

I also would like to have some "suspend mode", which toggles on/off the screen on demand.

I havent seen a screen burning yet - but could be a long run problem.

If anybody likes to invest time into the control if touchscreen element of the LCD we could add some "screensaver waking up on touchscreen" or "toggle on/off on touch" feature - that would be great.

But personally I would like to invest my dev time into the switch to a ePaper Display after version 1.0 anyway - like this one: https://www.waveshare.com/wiki/2.7inch_e-Paper_HAT_(B) No problems with screen burning or having a light emtting device anymore. Driving down energy consumption and finally some buttons for basic interaction directly with device.

+1 for the ePaper Display

e-paper solution is an good idea, but actually I prefer the touch screen.

Due to the fact that any touch feature works only under arbitrary condition in text mode I think one of the first issues should be an X-Server. You can run a console in graphic mode then after startup.

If you have an x-Server the needed steps to achieve touch features and screensavers are quite low.

also a web gui was easy to implement and software like ZAP desktop can be activated locally! I think that is the much more sustainable solution which offers by far more options for the raspiblitz (e.g. as a standalone POS for both smaller and bigger biz and also as an built-in piece of hardware for vending machines and others.

The idea is to make both possible - run the RaspiBlitz with the LCD or an ePaper. To make the ePaper possible there will be some changes in the future - introducting an display.service or something like that. Once this is there - anybody is free to extend the LCD from no-touch/ASCII to a touchscreen/Graphics mode from there on.

I will close this ticket for now - feel free to reopen it later on.
