The invention discloses an antitheft alarm realization method of a display device. The method includes the following steps: starting an antitheft alarm mode of a display device, and emitting infrared rays outwardly; receiving reflected infrared rays reflected by a barrier; reading the signal intensity value of the reflected infrared rays, and determining whether the signal intensity value of the reflected infrared rays meets a preset condition; and sending antitheft alarm information to a client that is bound to the display device if the signal intensity value of the reflected infrared rays meets the preset condition. The invention also discloses a display device. The method can determine a barrier on the basis of infrared reflected signals, and timely notifies clients such as users and/or property management sectors. The intelligence and the safety of the display device are improved, and economic losses of users are effectively reduced.
