Now, 3-D display technology is mature and widely used in display technology, and the LED display screen as the mainstream screen in the future will certainly use this technology. 3D display technology adopts a professional 3D control system, without changing the existing structure of floor tile LED display screens, using ordinary floor tile led display screens, through the extension of interactive display technology and the production of specific effects can have an immersive 3D three-dimensional feeling, plus the characteristics of LED with ultra-high brightness so that the display effect of the display screen is better than that of the LCD screen, which becomes an inevitable development trend of the display screen in the future.
7） Blanking circuit technology
if the refresh rate is too high, it will speed up the change of frame frequency, resulting in the residual small current of the uplink tube, and then make the uplink LED light emitting diode appear dark bright phenomenon, seriously affecting the consistency of the whole screen, especially after long time use, it will affect the overall life of the screen body to appear dead lamp and other phenomena.
8） Technology of face cover with buckle position
Nowadays, the surface cover of the product is fixed with screws, the number of screws is too much, the production and maintenance are very time-consuming, and the uneven power of electric batches when playing screws makes the surface cover deformed, which affects the flatness of the whole product. The technology of buckle-type surface cover will be another development trend for LED large screens.

Technology implementation
Functional block diagram for realizing interactive LED display: special-processed playback video source, first through the LED display to control special playback software in the computer, DVI output, connected to the main controller of video signal processing through the DVI cable, and then through the optical fiber Or the network cable is connected to the signal distributor, and the distribution displays the full picture of playback.
When the display screen interacts with the audience, the position sensor on the display screen detects the interaction point of the interactive audience, and the positioning controller of the display screen transmits the position coordinate information of this interaction point back to the LED display control computer to control the computer After receiving the position coordinate information, the control software can pass back to the LED display control computer according to the received coordinate information. After the control computer receives the position coordinate information, the control software can call differently according to the received coordinate information The program files and video files are played, and the pictures displayed on the LED display have corresponding real-time changes to achieve the effect of real-time interaction.
According to the necessary conditions and principles of interactive LED display screen, it is different from traditional LED display screen:
The first is the difference in control software. The traditional LED display screen at the playback end only needs ordinary playback software to play the video source and does not need to receive other signals. The interactive LED display is different. It not only needs to be able to play but also to receive the coordinate information of the interactive point returned from the display. After receiving the position coordinate information, the control software can call it according to the received coordinate information Different program files and video files are played. This is the same as when we play games on a computer. The LED display is like a computer monitor, the interactive audience is like a mouse, and the interaction point is like the position of the mouse. Clicking the mouse at a different position calls different programs.
second, the direction of data transmission is different. the data of a traditional LED display screen is mainly transmitted from the control end to the display end, which is basically one-way, and the interactive LED display screen adds data return, which belongs to two-way transmission.
The third is the difference in the display end of the LED screen. The traditional LED display only plays the role of the display, and the interactive LED display also needs to sense, collect, and transmit the coordinate information of the interactive point location of the interactive audience to locate the interactive point. This is the most important and critical part of the interactive LED display.
Interactive LED floor tile screen is mainly used in indoor and outdoor stage floor tile background. Floor tile screen is the result of scientific research and development and represents the future development direction of LED products.
The current interactive LED screen, DJ screen, Rubik’s Cube screen, spherical screen, and other special-shaped screen display equipment beneficial supplement, has been widely used in stage rental, singing and dancing parties, various press conferences, exhibitions, stadiums, theatres, auditoriums, lecture halls and so on, in the domestic and foreign markets, are very concerned; It also provides a promising market direction for full-color LED display manufacturers.
