The power circuit 11 receives an external power source to provide a normal electrical signal to drive the display 1G to operate. External data signals and control signals, such as audio signals, timing signals, video signals, etc., are transmitted from the signal input terminal 12 to the display 10. The signal control circuit 13 is connected to the signal input terminal 12 for receiving the control signal, and the other end is connected to the display module 14 and the built-in audio. The nickname control circuit 13 converts the data signal and the control signal input from the signal input terminal 12 to the built-in speaker 15 of the display module 14. The signal control circuit 13 includes an audio signal processing circuit ι31, a video signal processing circuit 132, and a timing control module 133. The audio signal processing circuit 131 performs audio effect control on the audio signal, and is outputted by 200828208. The audio 15 restores the sound. The video signal processing circuit I% - performs circuit conversion control on the video signal and transmits it to the display module μ. • realizes image display. The material control block 133 performs circuit conversion on the sequence signal. The sound is synchronized to the built-in audio 15 and the display module 。, and the sound image is synchronized. The built-in audio 15 is added to the display to realize the synchronous output of the image and the sound, thereby avoiding the use of the external connector sound. The inconvenience caused by the use of the user is satisfied that the user can enjoy both the face and the music. However, the order control module 133 can only control the audio signal and the video signal to synchronize the output, and the audio cannot be controlled. The signal and the video signal are separately separated, so that the built-in audio 15 of the display 10 cannot be separated from the display module 14 so as to be used separately from each other. When the user needs the audio signal output without the need for the image output, the display mode & 14 and the built-in audio day are in the working state, so the display can be used in the display mode. The audio signal or the video signal k is selectively outputted, which brings inconvenience to the user. [Invention content] ^ In view of the above, it is necessary to provide a display having a sound function in the shutdown mode and being convenient to use. _ —~ The TM includes a power supply circuit, a signal control circuit, a non-plate control circuit, and a display screen, wherein the signal control circuit includes a video signal processing circuit and an audio signal processing circuit, and the power supply is powered by the display device. The display mode control circuit is connected to the signal control and the display screen, and controls the signal output of the video signal processing circuit and the processing circuit of the audio signal No. 200828208. _ Compared with the prior art, adding a display to the display And the display mode control circuit is capable of separating the audio output from the video output in different rounds of the mode In the non-working state, the output of the audio signal can also be guaranteed. Use:: According to your preference, there are multiple selection modes to control the work of the display: root § when the image is not needed, the display can also be used as a sound, the user Gentleman. Another 'When no image display is required, the display screen = non-working evil, greatly saving energy.
