In one embodiment, the ambient light sensor may have a photosensitive surface facing the light outlet 213 of the light guide 210 to improve the photosensitive effect or accuracy of the ambient light sensor. For example, the light-sensing surface may face the light outlet 213. The external ambient light can enter from the light outlet 213, and is transmitted to the light outlet 213 through the light guide path of the light guide 210 and enters the photosensitive surface, so as to be sensed by the ambient light sensor.

In some embodiments, in order to allow the ambient light sensor to be flexibly arranged inside the housing, a reflective structure may also be arranged or mounted inside the housing, for example, the reflective structure may be arranged between the light outlet 213 and the ambient light sensor. The reflective structure is disposed between the light inlet 212 and the ambient light sensor, so that the ambient light entering from the light inlet 212 is reflected by the light guide path, the light outlet 213, and the reflective structure in sequence and then enters the ambient light sensor.

In some embodiments, in order to allow the ambient light sensor to be flexibly arranged inside the housing, a reflective structure may also be arranged or mounted inside the housing, for example, the reflective structure may be arranged between the light outlet 213 and the ambient light sensor. The reflective structure is disposed between the light inlet 212 and the ambient light sensor, so that the ambient light entering from the light inlet 212 is reflected by the light guide path, the light outlet 213, and the reflective structure in sequence and then enters the ambient light sensor. For example, the ambient light sensor may be disposed near the bottom of the housing and reflected from the light outlet 213 to the ambient light sensor via the reflective structure, and at this time, the ambient light sensor near the bottom of the housing may sense the ambient light. The reflecting structure may include a mirror having a light reflecting function, such as a reflective mirror.
