Abstract
The projection screen includes signal lines, photosensitive sensors and a signal processor. The photosensitive sensor is configured to sense a light beam for determining a remote control region from a remote control terminal. The signal line is configured to transmit to the signal processor the sensing signal generated by the photosensitive sensor after sensing the light beam. The signal processor is configured to determine position information about a position irradiated by the light beam. The display device can determine the remote control region in accordance with the position information determined by the signal processor about the position irradiated by the light beam, and receive an operation command from a command key of the remote control terminal so as to perform a remote control operation.
