What low cost LCD can I use in minus -30°C?
A number of your  photos are of OLED displays, which do not have the low temperature problem. For example this Vishay display specifies -40° operation.
Generally wide temperature range LCDs (such as for automotive applications) use a different liquid crystal formulation that requires a negative bias voltage. And they still may be quite pokey at very low temperatures.
So you may be better off with an OLED display if the disadvantages of that kind of display are not deal killers (such as aging and burn-in).
