DT028ATFT - Current consumption @ 3V3

I am looking for more electrical current specification for TFT. In current datasheet only the current consumption of backlight LED's are specified! In our application the display is supplied with 3.3 VDC. Anyone any manufacturer specification for this parameter?

The backlight LEDs are going consume the most power. See page 231 of ILI9341 specification. The max current consumption for standby is 100 uA.
I have measured the values for our similar 1.8" display. Awake (no backlight) is 1.68 mA. Sleeping (no backlight) is 57 uA.
