Embodiment Construction

[0031] Such as figure 1 As shown in the figure, it is a flow chart of the method for controlling the LED dot matrix display screen based on the mobile terminal. The mobile terminal-based LED dot matrix display control method is used for controlling the display screen through the mobile terminal in a display screen control system including the mobile terminal and the LED dot matrix display.

[0032] The mobile terminal is generally a mobile phone. In this embodiment, the mobile terminal can convert text, picture, video and other files into information with a specific format, and then transmit the information to the display screen through the communication module of the mobile phone, so that the display screen displays these contents. Wherein, the communication module of the mobile terminal refers to wireless transmission protocols similar to bluetooth, 3G network, WIFI and the like.

[0033] The display screen is generally an LED display screen, and in this embodiment, a cont...

Abstract

The invention discloses a light emitting diode (LED) dot matrix display screen control method based on a mobile terminal. The method is used for controlling an LED dot matrix display screen through the mobile terminal in a display screen control system comprising the mobile terminal and the LED dot matrix display screen. A marking code is preset on the display screen; and the display screen control method comprises the following steps that: the display screen communicates with the mobile terminal; the mobile terminal sends the marking code and an identification code for requesting to control the display screen to the display screen; when the marking code of the display screen is the same as that sent by the mobile terminal, the display screen receives the identification code sent by the mobile terminal and checks whether a corresponding control relation exists between the mobile terminal and the display screen according to the identification code; and if so, the display screen receives display control of the mobile terminal, otherwise, the display screen refuses the display control of the mobile terminal. The LED dot matrix display screen control method based on the mobile terminal, which is easy to operate and facilitates management of the mobile terminal, is implemented. Furthermore, the invention also provides an LED dot matrix display screen control system based on the mobile terminal.

Description

technical field [0001] The invention relates to a display screen control method, in particular to a mobile terminal-based LED dot matrix display control method and system. Background technique [0002] In today's society, large-scale LED dot-matrix displays are widely used, such as the display screens used to broadcast advertisements on high-rise buildings, the display screens used to introduce products in shopping malls, and other display screens used to play files. The playback display of the LED dot matrix display is controlled by the LED control card. The traditional control methods for the playback content mostly edit the content to be played in advance, and then transfer it to the LED through the computer serial port, U disk or SD card. In the memory of the control card, it is read by the LED control card and played repeatedly. Therefore, the traditional control method is not convenient for changing the playing content of the LED dot-matrix display, and it is also not...
