Abstract
An ambient light adjustment (ALA) apparatus, a method and a system therewith are proposed. The ALA apparatus includes a main body having a plurality of edges, one or more light sources, a light blocking layer and a controller. The light source is mounted on at least one edge of the ALA apparatus. The main body comprises at least one light guide plate. The light blocking layer is disposed over a surface of the main body. The controller is coupled to the light source and the light blocking layer. The ALA apparatus further comprises at least one sensor coupled to the controller. The controller controls the light characteristics of the light source and/or the light blockage levels of the light blocking layer to adjust ambient light characteristics, according to a sensed result by the sensor or sensors.
