Fig. 2 is the schematic diagram of structure of the display device of presentation graphs 1;
Fig. 3 is the schematic diagram of the structure of the expression display device that makes speaker system and radio receiver combination of the present invention;
Fig. 4 is the flow chart of the method for expression control display device of the present invention.
Referring to Fig. 3, the figure shows the display device that makes speaker system and radio receiver combination of the present invention.Be denoted by the same reference numerals with the identical or similar function square frame of function square frame shown in Figure 2 among this figure, therefore omit and describe in detail at this.
Display device of the present invention mainly comprises vision signal processing section, Audio Signal Processing part, radio reception part and control section.Be similar to the display device of Fig. 2, the vision signal processing section comprises video signal preprocessor 20, horizontal/vertical synchronization signals processor 22, multiplexer 32 and CRT 16.The Audio Signal Processing part also comprises amplifier 40 and loud speaker 12a, 12b.Control section of the present invention comprises control panel 60, monitor controller 65, memory 70, electronic switch 75 and osd controller 30.In addition, radio reception part 50 comprises antenna 51, electronic tuning unit 52 and demodulator 54.
In radio reception part 50, the control voltage that electronic tuning unit response controller 65 provides can be selected required radio frequency, and the frequency information of generation and selected frequency dependence (this frequency information sends controller 65 to as answer), electronic tuning unit 52 and demodulator 54 can be any common electronic tuning unit and demodulator.This frequency information comprises corresponding radio wave band (for example AM, FM
1, FM
2), pre-set channel number and frequency.Demodulator can be transformed to audio signal to selected radiofrequency signal.
In control section, control panel 60 is made up of the auxiliary keyboard of analogue-digital converter type, and this keyboard has a plurality of buttons that are used to control radio tuner and the volume of adjusting the output of screen display and audio frequency.The output of control panel 60 sends monitor controller 65 to, so that preset control signal according to each key input generation.Monitor controller 65 preferably is made up of single chip microcomputer, and the memory 70 of the frequency information that provides of storage radio tuner 52 is provided.An output at controller 65 is provided with an electronic switch 75, and it responds the control signal of self-controller 65, is connected to audio frequency amplifier 40 the audio frequency of demodulator 54 output with from the audio frequency input of computer system selectively.This electronic switch 75 comprise have a switching signal input, two signal input parts and be connected to solenoid relay (solenoid relay) switch of an output of amplifier 40.
Meanwhile, each control signal that controller 65 produces all offers osd controller 30, so that show output on the screen of the visual information of generation permission CRT 16 demonstration control operations.The output of OSD mixes with the output of video signal preprocessor 20 in multiplexer 32.In addition volume control signal is also offered audio frequency amplifier 40.
When operation, 65 pairs of monitor controllers are pressed the radio control key that is arranged on the control panel 60 and are responded, and produce one and preset control signal.For example, if press the radio turn-on key, an output of control pillar 65 produces a control signal, and this control signal is offered switch 75.Switch controlling signal has the voltage level that is enough to drive relay solenoid coil (solenoid coil).Then, switch 75 is changed into the audio output line road to its conductive path from the audio frequency incoming line of demodulator 54.In addition, adjust one of key if supress waveband selection key, channel selecting key and frequency, control signal corresponding just offers tuner 52, to select required wave band or channel or to adjust radio frequency.In addition, also this radio control signal is offered osd controller 30, go up total variation and the frequency adjustment process that shows signal is come display radio band or channel so that produce with the screen that presets of video signal mixture.
Below the operation of monitor controller 65 will be described referring to Fig. 4.In case display device energized, controller 65 are just carried out the key scanning operation of judging whether the button on the control panel 60 is pressed termly.At first judge whether to supress screen and adjust key in step 100.If press, controller 65 just produces control voltage at the operating value that step 110 is adjusted key according to screen.As mentioned above, the control voltage signal offers video signal preprocessor 20 or horizontal/vertical synchronization signals processor 22, so that adjust the display parameters of screen.Return the master control routine then.
If the button of pressing in step 100 is not that screen is adjusted key, just arrive step 210, judge whether the radio receiver in the display device is working.In other words, controller 65 is determined to be activated so that the output of demodulator 54 is connected to audio frequency amplifier 40 at initial condition switch 75.If not the radio on-state, just judge whether radio on/off key of the key press in step 220.If controller 65 just produces the voltage signal of driving switch 75 in step 230.If find that in step 210 display device is in the radio on-state, the key of pressing in step 240 judgement radio on/off key whether just.If controller 65 just stops to produce switching signal and stops radio adaptation in step 250.Return the master control routine then.
In step 240,, just shown in dashed rectangle 300, carry out the radio control operation consistent with the radio control key of pressing if the button of pressing is not a radio on/off key.Specifically, in step 310, judge whether to supress the radio wave band conversion key.If controller 65 just produces the control signal that changes radio wave band and sends this signal to tuner 52.So carry out required wave band conversion operations in step 320, the altered band class information in the tuner 52 are returned to controller 65 and be stored in the memory 70 as current wave band data.
If find that in step 310 key of pressing is not the wave band conversion key, just further judge whether to supress the radio channel conversion key in step 330.If controller 65 just produces the control signal that changes radio channel and sends this signal to tuner 52, so that carry out required channel conversion manipulation in step 340.Channel change information is stored in memory 70 as the current channel data.
At last, if find that in step 330 key of pressing is not a channel switching key, just further judge whether to supress radio frequency and adjust key in step 350.If controller 65 just produces the control signal that increases or reduce radio frequency, and send this signal to tuner 52, so that carry out required frequency adjustment operation in step 360.The frequency information of setting is stored in the memory 70 of controller 65, and returns main routine.
Also have, the step 320 of above-mentioned change radio wave band, the step 340 that changes channel and the step 360 of adjusting frequency and radio are switched on or switched off step 230,250 and also comprise each control signal is sent to osd controller so that showing the step that shows on the screen of corresponding control operation on the screen of display device.
As seen from the above description, display device of the present invention provides the radio reception function, this radio reception function need not installed independent radio receiver circuit plate in computer system, just strengthened multimedia environment by only display device being connected to computer system thus.
Though described the present invention with respect to one exemplary embodiment, can expect that can make various improvement to above description in the spirit of claim of the present invention and category implements the present invention.
