LED full-color display screen system controlled through smart phone

Abstract

The invention discloses an LED full-color display screen system controlled through a smart phone. The system comprises an LED display screen, a smart phone client-side, a display control terminal and a communication module. The smart phone client-side is connected with and in communication with the display control terminal through the communication module. The display control terminal comprises a main controller, an FPGA display control unit, a memorizer unit and a power supply unit. The smart phone client-side obtains user configuration parameters through a parameter configuration module, obtains display material data specified by a user through a material management module, and transmits the user configuration parameters and the material data to the main controller through a network management module. The main controller controls the FPGA display control unit to configure display screen parameters according to the user configuration parameters, transmits the display material data to the FPGA at the same time, and outputs corresponding material data by controlling the LED display screen through the FPGA. The user can conduct parameter control, data transmission and display control on the LED full-color display screen through the portable smart phone device, an existing system and an existing wiring structure are greatly simplified, and system cost is reduced.

Description

technical field [0001] The invention relates to the technical field of data transmission control, in particular to a system for controlling an LED full-color display screen by using a smart phone, which can conveniently use the smart phone to transmit display content to the LED display screen. Background technique [0002] In recent years, with the reduction of the price of LED display screen, the improvement of LED display color and video effect, and with the free assembly form, LED display screen is more and more widely used in various occasions, satisfying the needs of people in various fields. Advertisement, party, information release and many other application fields. Among them, the LED full-color display uses red, green, and blue light-emitting tubes to combine colors. When the gray level reaches 256, it can be combined into 16.77 million colors, which truly restores the colors of nature and greatly improves the display quality. The effects and uses of indoor and out...

Problems solved by technology

[0003] When the LED full-color display screen displays video and images, the amount of data is huge. The original data processing method uses a desktop computer, and a dedicated playback computer and display card are used for control. The program cannot be separated from the computer when it is played. The performance requirements of the graphics card are high, and the requirements for long-term operation are high.
