The display has the following pcb outline: 85,6mm width, 60,5mm height.

I tested it on my labbench power supply and with a UNI-T UT139C multimeter, 5V DC, and got the following results:
WITHOUT Raspberry attached
- Backlight 002% --> 169mA
Backlight 030% --> 227mA
Backlight 050% --> 269mA
Backlight 080% --> 341mA
Backlight 100% --> 391mA
- Backlight 002% --> 245mA
Backlight 030% --> 304mA
Backlight 050% --> 347mA
Backlight 080% --> 416mA
Backlight 100% --> 467mA
Are there any members who have a similar screen and can measure the power consumption?
Does the composite or DPI displays consume a similar amount of power?
