摘要： The present disclosure provides a display device, a control method thereof, and a computer storage medium, relating to the technical field of displays. The display device includes a control component, and the control component is configured to control a display component to operate; and control, in response to receiving a first control instruction, at least one of a near-field communication component and the display component such that a signal-sending period of the near-field communication component falls within an image-holding period of the display component, wherein the near-field communication component is configured to send a signal during the signal-sending period. According to the method, the signal-sending period is caused to be within the image-holding period by controlling at least one component of the near-field communication component and the display component during a display of the display component, such that the near-field communication component is prevented from affecting the image refresh of the display component when sending the signal, and thus the poor display effect of the display device in the related art is solved, and a display effect of the display device is further improved.
