Abstract
In a method of controlling display screen statuses and an apparatus, the method includes a signal emitter emitting a detection signal, and a first signal receiver and a second signal receiver receiving a reflection signal of the detection signal by an object. Intensity of the reflection signal received by the first signal receiver is compared with a first threshold for obtaining a first magnitude determination result. Intensity of the reflection signal received by the second signal receiver is compared with a second threshold for obtaining a second magnitude determination result. The display screen statuses are controlled based on the first magnitude determination result and the second magnitude determination result.
