Method and apparatus for controlling display screen statuses

An apparatus for controlling display screen statuses, being applicable to a terminal comprising a display screen, a control circuit, a first signal emitter, a second signal emitter, a first signal receiver, a second signal receiver, a first ambient brightness sensor, a second ambient brightness sensor, a first light through-hole, and a second light through-hole, wherein a distance between the second signal receiver and the first signal emitter is that between the first signal receiver and the first signal emitter, a distance between the second signal receiver and the second signal emitter is different from that between the first signal receiver and the second signal emitter, wherein the first light through-hole is used by the first signal emitter, the first signal receiver, and the first ambient brightness sensor, wherein the second light through-hole is used by the second signal emitter, the second signal receiver, and the second ambient brightness sensor, the control circuit is configured to detect whether the first signal emitter is able to emit a detection signal, the apparatus comprising:

• a first control module, configured to control the first signal emitter to emit the detection signal when the control circuit detects that the first signal emitter is able to emit the detection signal and configured to control the second signal emitter to emit the detection signal when the control circuit detects that the first signal emitter is unable to emit the detection signal;
• a second control module, configured to control the first signal receiver to receive a proximity light reflection signal of the detection signal reflected by an external object and to control the second signal receiver to receive a distant light reflection signal of the detection signal reflected by the external object;
• a first determining module, configured to compare intensity of the reflection signal received by the first signal receiver with a first threshold to obtain a first comparison result;
• a second determining module, configured to compare intensity of the reflection signal received by the second signal receiver with a second threshold to obtain a second comparison result;
• and
• a third control module, configured to control statuses of the display screen according to the first comparison result and the second comparison result.
