Abstract
Provided are a method and apparatus for controlling display screen statuses. The method includes the following. A detection signal is transmitted by a signal emitter. A proximity light reflection signal of the detection signal reflected by an external object is received by a first signal receiver and a distant light reflection signal of the detection signal reflected by the external object is received by a second signal receiver. Intensity of the reflection signal received by the first signal receiver is compared with a first threshold to obtain a first comparison result. Intensity of the reflection signal received by the second signal receiver is compared with a second threshold to obtain a second comparison result. Control statuses of the display screen according to the first comparison result and the second comparison result.
