Power consumption of 1.3 OLED vs new 1.3 TFT LCD?

by alanc98 on Tue Aug 13, 2019 8:33 am

I have a battery powered project that uses the Adafruit 1.3 OLED breakout board:

The new 1.3 TFT LCD is a very tempting upgrade, especially at a lower price!

Does anyone know the relative power consumption of the two?
I would probably stick with the OLED screen if the TFT used significantly more power.

Thanks!

The LCD itself uses very little. But the backlight is fairly power hungry. You can save power by turning the backlight off.

The power consumption of the OLED depends on how many pixels are lit. With the screen blanked, consumption is very low. But at full-white, it will pull more than the LCD with backlight on. In typical usage, it is probably the same or lower consumption than the LCD.

Very interesting! I'll have to check out one of these TFT displays soon!
Thanks,
