Interactive LED Creative display is an innovative display technology that achieves a unique display effect by combining interactivity and LED technology. The classification of this display is mainly based on its function. The following will introduce several common categories of interactive creative displays and their functional implementation.

First, the classification of interactive LED creative display

1. Touch interaction
Capacitive touch LED screen: touch operation through the current induction of the human body. It has the characteristics of fast response speed and precise multi-touch control. It is suitable for the occasions that require high interactive operation, such as commercial display, education and teaching. For example, in the exhibition of the museum, the audience can get detailed information about the exhibits and multimedia display by touching the LED display.

Infrared touch LED screen: Use the occlusion of infrared light to detect the touch position. The cost is relatively low and the stability is good. Widely used in a variety of indoor and outdoor display occasions, such as shopping malls advertising screens, conference room displays, etc. For example, on the shopping guide screen in the mall, customers can query the store location and promotional activities through infrared touch operation.

2. Somatosensory interaction
Camera-based motion-sensing interactive LED screen: capture human movements through the camera, and use image recognition and analysis technology to achieve interaction. It can provide a more natural and intuitive interactive experience, which is suitable for game entertainment, advertising and other fields. For example, in the arcade, players can play interactive games with the interactive LED display through body movements.

Sensor-based motion sensing interactive LED display: The use of various sensors (such as acceleration sensors, gyroscopes, etc.) to detect the movement and posture of the human body to achieve interaction. This type of display is often used in conjunction with a wearable or handheld device to enhance the fun and engagement of the interaction. For example, in some theme park interactive experience projects, visitors wear sensor devices, interact with interactive creative displays, and feel immersive virtual scenes.


3. Voice recognition
This kind of display can recognize the user's voice commands through the built-in sound sensor. Users can interact with the display via voice to trigger specific functions and effects. For example, users can speak a specified password to start a specific display, or voice control creative display to play, pause, and other operations. Voice recognition interactive LED creative display is often used in showrooms, conference rooms, smart homes and other fields, providing a more convenient and natural way for human-computer interaction.

Second, the realization of interactive creative screen functions

1. Hardware components
LED display: A display unit composed of multiple LED modules, responsible for the display of images and videos. The quality of the LED module determines the display brightness, color restoration degree, contrast and other display effects.

Touch sensors or motion-sensing sensors: Depending on the type of interaction, install the appropriate sensor. The touch sensor is used to detect the user's touch operation, and the somatosensory sensor is used to capture the human body's movement and posture. The accuracy and response speed of the sensor directly affect the effect of the interaction.

Controller: responsible for processing the signal from the sensor, controlling the display content of the LED display, and communicating with external devices. The performance of the controller determines the interactive response speed, stability and functional scalability of the display.

Communication module: used for data transmission with external devices, such as receiving control instructions, uploading interactive data, etc. The communication module can support wired network (such as Ethernet), wireless network (such as Wi-Fi, Bluetooth) and other communication modes.

Power module: Provides stable power supply for the display. The quality and stability of the power module directly affect the normal running of the display.


2. Software system
Operating system: Provides basic operating environment and management functions for interactive LED display, such as task scheduling, memory management, device drivers, etc. Common operating systems include Android and Windows.

Interactive software: to achieve specific interactive functions, such as touch operation response, motion sensing interactive algorithm, projection fusion, etc. Interactive software is usually customized by developers according to different application scenarios, which can provide rich interactive effects and user experience.

Content management system: used to manage the display content on the display screen, such as pictures, videos, text, etc. The content management system can easily update and publish content to meet different display needs.

3. Data processing and transmission
Data acquisition: The sensor collects the user's operational data or environmental data, such as touch position, movement posture, projected images, etc. These data are preprocessed and transmitted to the controller for further processing.

Data processing: The controller analyzes and processes the collected data and generates corresponding responses according to preset algorithms and logic. For example, in touch interaction, the controller determines the user's operation intention according to the touch location, and then performs the corresponding operation; In the motion-sensing interaction, the controller recognizes the user's movement and posture by analyzing the data of the motion-sensing sensor, and gives corresponding feedback.

Data transmission: If the interactive display requires data interaction with external devices, such as data synchronization with the server, receiving remote control instructions, etc., data transmission is required through the communication module. Data transmission can be wired or wireless network mode, according to the actual needs to choose the appropriate transmission protocol and technology.
