My LA01 52mm wideband display is very poor in daylight.
The luminence is nice and bright when you 1st switch on the ignition then it dims.
No matter whether I shine light or cover the LDR (Light Dependant Resistor) is doesn't seem to get brighter or dimmer.

My old LD01 display (brick) used to change luminence when going under tree's or street lamps.
