An electrical device, an audio frequency spectrum display circuit and a control method thereof

Abstract

The invention discloses an electrical equipment, an audio frequency spectrum display circuit and a control method thereof, wherein the audio frequency spectrum display circuit is interfaced with the main board of the electrical equipment, and the audio frequency spectrum display circuit comprises a control module, a driving module and an array of cold light sheets The control module receives the control signal output by the main board interface and transmits it to the driving module to control the working state of the driving module; the driving module outputs the driving signal to the EL array according to the audio signal output by the main board interface when it is turned on, and controls the When the corresponding area of ​​the EL array is turned on or off, the audio spectrum is intuitively reflected by the EL, and rhythms with the change of the audio spectrum to achieve colorful sound and light effects and enhance the aesthetic and technological sense of electrical equipment.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to an electrical device, an audio frequency spectrum display circuit and a control method thereof. Background technique [0002] The functions of the current television equipment are becoming more and more diversified, but during audio playback, the audio signal cannot be directly reflected in a dynamic form; although there are audio frequency spectrum display devices on the market, their structure is more complicated , There is no general implementation method, which limits the development of the audio frequency spectrum display industry. [0003] Therefore, the existing technology needs to be improved and improved. Summary of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an electrical equipment, an audio frequency spectrum display circuit and a control method thereof, which use a cold light film to...
