On October 21, the shuttle is replacing the processing of page circuit conversion, video amplification, image mode control, etc., and the clock signal processing circuit 443 filters the received clock signal. The X-axis control circuit 45 includes a timing control module 451, an audio signal wheel output interface 452, and a video signal output interface 453. The display mode control circuit 45 outputs video signals and audio signals from the signal control circuit 44. And the output mode of the timing signal is controlled. The timing control module 451 generates a timing control signal to control the output of the video signal and the audio signal. The timing control module 451 can issue a control signal to synchronize the video φ signal and the audio signal; and can also send a control signal to enable the The video signal stops outputting, and the audio signal is kept output; the control signal can also be sent to output the video signal to stop the output of the audio signal. The audio signal output interface 452 and the video signal output interface 453 respectively output audio signals and video signals controlled by the timing control module 451. [0016] The display screen 46 is used to display an image, which may be a liquid crystal display, a plasma display or a cathode ray tube display. The display 46 further includes a #cut/open the display 46. The power switch 461 is disposed outside the display screen 46. [0017] The built-in speaker 47 is configured to restore the sound of the audio signal processed by the signal control circuit 44 to release the sound effect. The operating principle of the display 40 is that the power supply circuit 41 provides various normal operating voltages. The audio signal and the clock signal input from the outside are transmitted to the signal control circuit 44 via the low frequency signal input terminal 42 while the video is input from the outside. The signal is transmitted to the signal control terminal through the video signal wheel terminal 43 to the digital control unit 1003391762-0 095149717. Form number A0101 page 7/15 pages 100 years. October 21st, by the replacement circuit 44, the signal control circuit 44 receives The audio signal is a video signal and a 4-clock signal. The audio signal processing circuit 441 performs a frequency effect control on the audio signal. The video signal processing circuit 442 controls an image mode of the video signal.

The display mode control circuit 45 receives the audio signal and the video signal processed by the signal control circuit 44, and performs output control thereof according to actual output requirements. The timing control module 451 sends a timing control signal to respectively control whether the audio signal and the output of the video signal are output; The display screen 46 is connected to the video signal output interface 453 and receives the video signal controlled by the display mode control circuit 45. The built-in audio 47 is connected to the audio signal output interface 452 and received by the display mode control circuit 45. Audio signal. [0019] Specifically, the display mode control circuit 45 has the following three output modes for the signal output: [0020] The first type, that is, the display screen 46 receives the video signal for image display, and the built-in sound 47 receives the audio signal. Performing a sound restoration; [0021] Second, the built-in audio 47 receives the audio signal for sound restoration, and the display screen 46 has no image display; [0022] Third, when the timing control module 451 outputs timing Controlling the message only when the video signal is output, the display 46 receives the video signal for image display, and the built-in audio 47 does not perform sound restoration on the audio signal. [0023] In the display 40, the timing is The control module 451 sets three working modes, each of which corresponds to one output mode, that is, when switching 059149717 form number Α 0101 page 8 / total 15 pages 1003391762-0 1356360 参100年. October 21 press positive ^ When the timing control module 451 is in the synchronous output mode of the video signal and the audio signal, the display 40 can synchronously display the image and restore the sound: when switching When the timing control module .451 is in the working mode of outputting only the audio signal, the display 40 only restores the sound, and the display screen 46 cannot display the image, and correspondingly switches the switch 461 to stop supplying power to the display screen 46; When the timing control module 451 outputs the timing control signal only when the video signal is output, the display screen 46 receives the video signal for image display, and the built-in audio 47 does not perform sound restoration on the audio signal. The switching of the timing control module 451 can be implemented by a remote controller (not shown), and can also be implemented by a menu control button connected to the timing control module 451. The menu control button is disposed outside the display screen 46. . The built-in sound 47 can also use an external sound, and a peripheral device such as a bite earphone is directly connected to the audio signal output interface 452 to realize sound reduction β. [0024] Compared with the prior art, the display mode control circuit 45 is added to the display 40. And the display mode control circuit 45 can switch between the previously set and the output mode to separate the audio output from the video wheel, and the display 40 can not only output the video signal and the audio gas number synchronously, but also enable When the display screen 46 is in the non-working state, the output of the external frequency signal can also be saved, and the user can have multiple selection modes according to his or her preference, which is convenient to use. [0025] In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law.
