The JE100 uses a transmissive LCD screen. For a LCD screen to be easily readable outside, it needs to be reflective (no backlight) or transflective (best of both worlds).

A transflective liquid crystal display is a liquid crystal display (LCD) that reflects and transmits light (transflective = transmissive + reflective). Under bright illumination (e.g. when exposed to daylight) the display acts mainly as a reflective display with the contrast being constant with illuminance. Only in dim and dark ambient situations an auxiliary transmissive backlight should be provided. When an illuminance sensor is added for control of the backlight, such a transflective LCD can be read over a wide range of illuminance levels. This is why that technique is often found in automotive instrumentation. In portable electronic devices the transflective mode of operation helps to save battery charge, since in bright environments no backlighting is required.
