Some questions about displays

I would like to make a display to read some important values of my Home Assistent system. I succeeded to show some values on a tiny 0.96 inch oled screen. I have used an esp32 board and esphome.

Now I have a few questions before I will buy a display.

I have seen two displays on AliExpress:

A tft one:
[TFT](Ik heb net dit geweldige item op AliExpress gevonden. Bekijk het nu! €7,50 32%OFF | 4 Inch Tft Kleur Touch Lcd Display Module 800*480 Ips Scherm Kan Direct Worden Ingevoegd In Arduino Mega2560 Ontwikkeling Board https://a.aliexpress.com/_EJ5dtEN)

And an e-ink version:
[E-ink](Ik heb net dit geweldige item op AliExpress gevonden. Bekijk het nu! €29,44 40%OFF | Waveshare 4.2 Inch E-Ink Display Module Voor Raspberry Pi 4 B E-Papier Module https://a.aliexpress.com/_EzAOCWh)

I have a few questions.

0
Am I right that I can use both displays with esphome, connected to an esp32 board?

1
Are there specific reasons to choose one display type over the other (tft vs e-ink) or is this a matter of personal opinion?

2
Is it possible with each of those displays to create several pages to display values of different sensors?

3
If yes, is it possible to change pages with a button connected to the esp32 board?

4
Is it a problem if those displays are turned on whole day?

5
Is it possible or advisable to turn the display automatically off after some time and turn it on by for example a proximity sensor, connected to the same esp32 board?

You might want to some research on e-ink.

Pros:

  • Literary consumes nothing at rest. Only when refreshing is any power consumed.
  • Paper-like clarity

Cons:

  • Extremely slow to refresh (4s / frame for the one you mention)
  • Usually max 3 colors (white / black / red). The one you mention is monochrome.

Thank you! That is interesting info!
I was not aware of the refresh time.

But if I have values which are not changing that fast, it may be an idea to update the display only a few times an hour, so it is not a big deal if refreshing takes a few seconds.
And if I take a bare esp32 chip, so without developer board and I let it go into deep sleep, I even may consider powering it by battery?

On the other hand, a tft display seems the cheaper and perhaps easier way?
It is not a very big deal for me to add 230V power…

Other pro’s and contra’s fir tft and e-ink?

And what about if it’s a problem if the tft display is on whole the time?

I have the display working! For now, it is a test with several dummy values.

I only noticed very poor colors, yellow is for example more like faded out brown.

I assume it is the low quality of the cheap displays or is there some setting in esphome to enhance the colors a bit?
