Abstract
A wide and narrow viewing angle-switchable display device and a control method are provided. The control method includes: acquiring action information of a user; comparing the action information with a stored action; and when the action information is matched with the stored action, sending a wide and narrow viewing angle switching signal, and controlling switching between wide and narrow viewing angle modes. The action information of the user is acquired and compared with the stored action, then the wide and narrow viewing angle switching signal is sent according to the comparison result, and the switching between the wide and narrow viewing angle modes is controlled; in this way, a sensor, such as an infrared sensor, an ultrasonic sensor, and an image sensor, can be directly arranged to acquire the action information of the user.
