Abstract

The invention discloses a multifunctional LED dot matrix display screen, relates to the technical field of LED dot matrix display screens, and solves the technical problem that an LED display screen in the prior art can only present a single static picture. The multifunctional LED dot matrix display screen comprises a control plate, a mounting frame, a LED dot matrix screen and a MCU, wherein theMCU is mounted on the control plate; the control plate is fixed in the mounting frame; the LED dot matrix screen is mounted on the mounting frame through bolts; and the control plate is integrated with an audio spectrum data acquiring circuit which is connected with the MCU through an AD (analog-digital) conversion interface. According to the multifunctional LED dot matrix display screen, the LEDdot matrix screen is used as a carrier, when music is played, the audio spectrum data acquiring circuit on the control panel acquires an audio signals, the MCU performs fast Fourier transform (FFT) processing on the audio signals, calculates the spectrum of audio and sends the spectrum to the LED dot matrix screen for display, so that the picture of the spectrum jumps along with the rhythm of themusic, and a user can experience the impact caused by the music audibly and visually.

Description

technical field [0001] The invention relates to the technical field of LED dot-matrix display screens, in particular to a multifunctional LED dot-matrix display screen. Background technique [0002] The LED electronic display screen is a display screen composed of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels evenly arranged. It uses different materials to manufacture LED pixels of different colors. With the development of society and the improvement of people's material and cultural level, the decoration of homes, entertainment places and public places has become an indispensable part of people's life, and people's requirements for hearing and vision in the living environment are also getting higher and higher. [0003] LED display screens in the prior art often have a single function, and the displayed picture is a single static picture, which can only display static text information, resulting in poor entertainment and interactivi...
