In addition, in the above embodiment, the odor controller 400 is implemented by using the atomizer 410, and in practical applications, the odor controller 400 may also be implemented by using other structures, such as:

in other embodiments, the odor controller 400 may also be controlled by air pressure, and the touch screen 200 is not provided with a piezoelectric plate for atomizing the essence solution, but is provided with an odor outlet. As shown, the odor controller 400 includes at least one air outlet disposed on the touch screen 200, which may be located on the same side of the touch screen 200 as the vibration driver 300, or not located on the same side as the vibration driver 300.

The number of the air outlet holes can be multiple, and one air outlet hole corresponds to one odor raw material; or, a plurality of ventholes correspond a smell raw materials for it is more even to give vent to anger. Wherein the duct of the air outlet is not connected to the touch screen 200.

The odor generation mode can be realized by the air flow of the odor raw material, and the air drives the odor small molecules to diffuse through the odor raw material.

In some embodiments, the interactive display device further comprises:

a processor, configured to control the vibration driver 300 to drive the touch screen 200 to vibrate at a predetermined resonant frequency and/or control the odor controller 400 to emit the odor when a predetermined instruction is received;

wherein the predetermined instruction comprises a marking touch gesture performed by the user on the touch screen 200.

In the above solution, the processor may be a main control board of the display device, and the main control board may control the vibration driver 300 and the odor controller 400 to operate when receiving a predetermined instruction.

The predetermined instruction may be a marked touch gesture performed on the touch screen 200 by the user according to the received touch information.

Furthermore, the interactive display device may further include: a sound module and other modules (not shown). The sound module can be connected with a circuit main control board of the interactive display device for control, and the sound module can be a loudspeaker for example.

The control flow of the interactive display device is described below with respect to the flowchart shown in fig. 9 as follows:

a user finger touches the touch screen 200;

the touch screen 200 sends a touch signal executed by a user on the touch screen 200 to the processor, wherein the touch signal comprises a touch position and the like;

when the display graphics of the display screen 100 include the special mark graphics, the processor analyzes the finger touch condition, and determines whether a first mark touch gesture exists, where the first mark touch gesture includes: the user touches a special mark graph and the like;

if yes, the processor generates a driving waveform signal matched with the special mark pattern, the vibration driver 300 drives the touch screen 200 to vibrate according to the driving waveform signal, and the odor controller 400 emits odor according to the driving waveform signal;

updating the display content and the sound content of the display screen 100 including the special mark graphics, continuously driving the touch screen 200 to vibrate by the vibration driver 300, and/or continuously emitting the odor by the odor controller 400;

the processor analyzes the finger touch condition, and determines whether a second marked touch gesture exists, where the second marked touch gesture includes: a finger passes through a special mark pattern and the like;

if yes, the processor controls the vibration driver 300 to stop driving the touch screen 200 to vibrate;

and controls the scent controller 400 to stop releasing the scent at a predetermined time point before the end of the display content and the sound content corresponding to the special mark pattern in the display content.

Taking the display content of the interactive display device as a fruit cutting game as an example, the specific flow is as follows:

in order to match the time of finger touch and the smell release time, a special fruit graphic is set in the display content. The special fruit pattern has a visible special mark pattern, when a user's finger cuts the special fruit pattern, that is, when the user's finger touches the special fruit pattern, the vibration driver 300 is controlled to drive the touch screen 200 to vibrate so as to transmit the touch feeling of cutting fruit, and simultaneously, an instruction is sent to the odor controller 400 to start emitting the odor of the corresponding fruit;

when the game is continuously executed, the picture display content and the sound content are updated, and a plurality of fruits same as the cut special fruit graphics are displayed on the picture, the same smell as the special fruit graphics is emitted, the special fruit graphics are maintained for a period of time, and meanwhile, the game fun and the smell feeling of the cut fruits are met;

pausing the game, jumping the picture to a video comprising the special fruit graph, wherein the video is an advertisement or other videos, for example, the special fruit graph cut by the user is a sweet orange, the special fruit graph cut by the user is a movie, and the special fruit graph is a smell emission, for example, an orange juice advertisement;

the game is paused, the smell is diffused, the picture only prompts to feel the smell, and the display picture has some light and shadow effects without contents.
