to make the display device meet the requirement of people according to the distance between people and the display device, as shown in fig. 4, the display device further includes a distance measuring mechanism 5, the distance measuring mechanism 5 is disposed on the supporting mechanism, the distance measuring mechanism 5 is connected to the control mechanism 6, a distance threshold is preset in the control mechanism 6, the distance measuring mechanism 5 is used for detecting the distance information between the human body and the supporting mechanism and transmitting the distance information to the control mechanism 6, when the distance is greater than the distance threshold, the control mechanism 6 controls the transparent display 2 to enlarge and play the video, and the control mechanism 6 controls the polymer dispersed liquid crystal film 3 to close, when the distance is less than the distance threshold, the control mechanism 6 controls the transparent display 2 to reduce and play the video, and the control mechanism 6 controls the polymer dispersed liquid crystal film 3 to open.
The distance measuring mechanism 5 can be a distance measuring sensor or an intelligent floor tile.
When people are far away from the display device, namely, the distance between people and the display device is larger than a distance threshold value, the control mechanism 6 controls the transparent display screen 2 to amplify a played video, and meanwhile, the control mechanism 6 controls the polymer dispersed liquid crystal film 3 to be closed, so that people can clearly watch notification videos and know commodities of merchants at a far distance.
, in order to make people control the display device according to the requirement, so that people can see the goods in the cabinet 7 clearly by manually controlling the display device in front of the counter, the display device provided by this embodiment further includes a switch, the switch is disposed outside the supporting mechanism and connected with the supporting mechanism, the switch is connected with the control mechanism 6, the control mechanism 6 is used to control the transparent display screen 2 to zoom out and play the video, and the control mechanism 6 controls the polymer dispersed liquid crystal film 3 to open.
When people are far away from the display device, the transparent display screen 2 plays the video in an amplifying mode, the polymer dispersed liquid crystal film 3 is closed, and people can clearly watch the video at the far distance to know the commodities of the merchant.
When people are close to the display device, namely people stand in front of the cabinet body 7 and want to watch commodities in the cabinet body 7, in order to avoid that played on the transparent display screen 2 affects the watching of the commodities in the cabinet body 7, people can press the switch to enable the control mechanism 6 to control the transparent display screen 2 to reduce the played video and control the opening of the polymer dispersed liquid crystal film 3, so that the people can clearly watch the commodities in the cabinet body 7 through the display device, the effect of watching solid commodities by the people when the video is amplified and played is avoided, and people can also watch informed videos when people lift up.
, in order to meet the demand of more people, the display device of this embodiment has a preset display time in the control mechanism 6, and when the display time is elapsed after the transparent display screen 2 reduces the display video, the control mechanism 6 controls the transparent display screen 2 to enlarge the display video, and the control mechanism 6 controls the polymer dispersed liquid crystal film 3 to close.
When someone reduces the broadcast video through switch control transparent display screen 2, polymer dispersed liquid crystal film 3 opens the back simultaneously, after the time is long after the predetermined demonstration, control mechanism 6 control transparent display screen 2 enlargies the broadcast video, and polymer dispersed liquid crystal film 3 closes simultaneously, can avoid people to have watched that plays on transparent display screen 2 behind the cabinet body 7 and report the unable automatically magnification of video and satisfy masses 'demand's problem.
So design, in time when someone is in apart from the threshold value within range, that plays on the transparent display screen 2 notice the video and also can enlarge automatically, avoid someone to stand in apart from the threshold value within range directly, influence other people and watch and report the problem of video.
By the design, the requirement that people watch the physical commodity can be met, and the requirement that other people watch notice can also be met.
, in order to make it possible for the user to transmit the video content to be played to the control mechanism 6 according to the requirement, the control mechanism 6 includes a storage module for connecting with an external device so that the external device can transmit notification information to the storage module.
The user may transmit different notification messages into the storage module as needed to cause the display device to play a product notification that the user wants to push .
