Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 1, the preferred embodiment of display screen 100 of the present invention comprises panel 1, processor 2, and a memory body 3.The setting value of memory body 3 in order to produce after storing automatic calibration, and in order to store a form (as shown in following table one), this form comprises multiple group, as the group A ~ G in following table one.Respectively this group comprises the close resolution of multiple sequential.Illustrate for group B, the time sequence parameter (vertical frequency, horizontal frequency, level T.T., vertical polarization, horizontal polarization) of resolution 1280 × 768-60Hz, 1360 × 768-60Hz and 1366 × 768-60Hz is very close.
Table one
As shown in Figure 2, be when display screen 100 receives an analog video input signal, display screen 100 carries out the process flow diagram set.First as shown in step S01 and S02, when display screen 100 receives an analog video input signal (being a VGA signal in the present embodiment), processor 2 can judge the resolution of analog video input signal according to the time sequence parameter of analog video input signal.In the present embodiment, the resolution of analog video input signal is essentially 1360 × 768-60Hz, and processor 2 judges that the resolution of analog video input signal is 1366 × 768-60Hz.
Then step S03 is in order to judge whether this analog video input signal carried out the setting of step S05 to step S13, if having, then carries out step S04 and step S14 and then completes setting, if nothing, then carry out step S05.The detailed content of step S03 and step S04 will be gone later again and be described in detail.In the present embodiment, this analog video input signal had not carried out the setting of step S05 to step S13, therefore then will carry out step S05.
The resolution that in step S05, whether processor 2 will have this display screen 100 to judge in the form judged in memory body 3.If nothing, then represent this resolution in standard specification without the resolution that other sequential is close with it, so then carry out step S13 and S14, processor 2 is applied mechanically its resolution judged and is produced to carry out automatic calibration (Auto Adjust) and comprise that level is counted, the isoparametric setting value of phase place and position, and processor 2 is applied mechanically this setting value with control panel 1 and shown this analog video input signal; If the resolution having this display screen 100 to judge in the form in memory body 3, then represent that this resolution exists other sequential resolution close with it in standard specification, so then carry out step S06.In the present embodiment, processor 2 judges that the resolution of analog video input signal is 1366 × 768-60Hz, and this resolution belongs to the resolution of the group B of this form, therefore next can carry out step S06.
Consult Fig. 1 to Fig. 3, step S06 is that this processor 2 controls this panel 1 and shows a menu picture (the menu picture of the present embodiment is screen display (OSD) picture as shown in Figure 3), this menu picture prompting processor 2 judges the result of this analog video input signal resolution, and list all resolution of this resolution group belonging in this form, the namely resolution of sequential similar to this resolution.In the present embodiment, processor 2 judges that the resolution of this analog video input signal is 1366 × 768-60Hz, the resolution therefore judged with the option of " automatically (1366 × 768) " prompting processor 2 in OSD menu picture by this set of options for default option.OSD menu picture also lists all resolution " 1280 × 768 " in the group B belonging to this resolution, " 1366 × 768 " and " 1360 × 768 " are selected for user.Whereby, whether correctly can pass through the resolution that user confirms that processor 2 judges, if processor 2 misjudgment, then correct resolution can be selected to overlap to avoid processor 2 to produce the situation of fuzzy pictures because erroneous judgement resolution for processor 2 by user.To operate and the flow process confirmed is carried out in step S07 to step S10 by OSD menu picture for user.
Consult Fig. 1 to Fig. 4, step S07 is that processor 2 judges whether user changes OSD menu by the resolution selected, if having, then carries out step S09 after carrying out step S08; If not, then directly S09 is carried out.Step S08 changes OSD menu picture by the resolution selected, and the resolution being about to point out user apply mechanically is changed.In the present embodiment, user changes in OSD menu picture by the resolution selected, the resolution being about to apply mechanically is changed to " 1360 × 768 " by " automatically (1366 × 768) " given tacit consent to, therefore processor 2 performs step S08 control OSD menu picture is the state of Fig. 4 by the Status Change of Fig. 3, then performs step S09.
Step S09 is that processor 2 judges that whether the non-input control signal of user changes the time of OSD menu picture more than a default time (such as 5 seconds), if exceeded this default time, be used as user's adjusted to the resolution for selecting, so then perform step S11; If do not exceed this default time, then carry out step 10: processor 2 judges whether user confirms that this is by the resolution (such as pressing input (Enter) key for display screen 100) selected.If user confirms that this is by the resolution selected, then carry out step S11; If user unconfirmed this by the resolution selected, then carry out step S07.
Step S11 is after user confirms selected resolution, and processor 2 judges that whether this is identical with the resolution that processor 2 judges by the resolution selected, if different, then carries out step S13 after carrying out step S12; If identical, then directly carry out resolution that step S13 judges with this display screen 100 and be about to the resolution of applying mechanically as this.Step S12 be processor 2 with this by the resolution selected as the resolution being about to apply mechanically.In the present embodiment, the resolution " 1360 × 768 " that user selects is different from the resolution 1366 × 768 that display screen 100 judges, therefore processor 2 can perform step S12 using 1360 × 768 as the resolution being about to apply mechanically.
Step S13 is that processor 2 is applied mechanically this chosen resolution and carried out automatic calibration and produce setting value, and the level that setting value comprises to adjust panel 1 display simulation video signal input signal is counted, phase place and position.And, the setting value produced after the resolution that this analog video input signal is also selected by processor 2 and automatic calibration is stored in memory body 3 (the present embodiment is that the temporal aspect of this analog video input signal or sequential table pointer (timing table index) are stored in nonvolatile memory), when this display screen 100 receives this analog video input signal again, this processor 2 shows this analog video input signal, the namely content of step S03 and step S04 according to this panel 1 of set value calculation stored in this memory body 3.Step S03 is that processor 2 judges whether there is the setting value that this analog video input signal is corresponding in memory body 3, if having, then carries out step S04, reads corresponding setting value.
Finally, then carry out step S14 after completing steps S13, this processor 2 is applied mechanically setting value and is shown this analog video input signal to control this panel 1.In the present embodiment, because the resolution being about to apply mechanically is modified to correct resolution 1360 × 768 by user, therefore processor 2 apply mechanically resolution 1360 × 768 carry out automatic calibration produce setting value, resolution 1360 × 768 corresponding for this analog video input signal and setting value are stored in memory body 3 by processor 2.Then, processor 2 is applied mechanically setting value and is shown this analog video input signal to control this panel 1, produces correct picture clearly.
Resolution selected by user still may be wrong, and cause the fuzzy pictures of display screen, and the display screen 100 of the present embodiment also has another mechanism and supplies user's active accommodation resolution and carry out automatic calibration.As shown in Figure 5, be when the panel 1 of display screen 100 shows this analog video input signal, if display screen 100 receives a correction instruction, display screen 100 carries out the process flow diagram set, and produces when this correction instruction is and is pressed by a button of display screen 100.First as shown in step S15 and S16, when display screen 100 receives this correction instruction (the present embodiment is the automatic calibration hot key (Auto Adjust HotKey) that user presses display screen 100), processor 2 can judge the resolution of analog video input signal according to the time sequence parameter of analog video input signal.
Then as step S17, whether processor 2 will have this display screen 100 to judge resolution in the form judged in memory body 3.If nothing, then represent this resolution in standard specification without the resolution that other sequential is close with it, so then carry out step S25 and S26, processor 2 is applied mechanically its resolution judged and is carried out automatic calibration and produce a new setting value, and processor 2 is applied mechanically this setting value and shown this analog video input signal with control panel 1; If the resolution having this display screen 100 to judge in the form in memory body 3, then represent that this resolution exists other sequential resolution close with it in standard specification, so then carry out step S18.
Step S18 is that this processor 2 controls this panel 1 and shows this OSD menu picture, this menu picture prompting processor 2 judges the result of this analog video input signal resolution, and list all resolution of this resolution group belonging in this form, the namely resolution of sequential similar to this resolution.Whereby, if previously to this analog video input signal the resolution selected be wrong, can pass through this process step and select correct resolution.To operate and the flow process confirmed is carried out in step S19 to step S22 by OSD menu picture for user.
Step S19 is that processor 2 judges whether user changes OSD menu picture by the resolution selected, if having, then carries out step S21 after carrying out step S20; If nothing, then directly carry out S21.Step S20 changes OSD menu picture by the resolution selected, and the resolution being about to point out user apply mechanically is changed.
Step S21 is that processor 2 judges whether the time of user's non-input control signal change OSD menu picture exceedes this default time, if exceeded this default time, is used as user's adjusted to the resolution for selecting, so then perform step S23; If do not exceed this default time, then carry out step 22: processor 2 judges whether user confirms that this is by the resolution (such as pressing input (Enter) key for display screen 100) selected.If user confirms that this is by the resolution selected, then carry out step S23; If user unconfirmed this by the resolution selected, then carry out step S19.
Step S23 is after user confirms selected resolution, and processor 2 judges that whether this is identical with the resolution that processor 2 judges by the resolution selected, if different, then carries out step S25 after carrying out step S24; If identical, then directly carry out resolution that step S25 judges with this display screen 100 as the resolution being about to apply mechanically.Step S24 be processor 2 with this by the resolution selected as the resolution being about to apply mechanically.
To be processor 2 carry out automatic calibration with selected resolution to step S25 produces new setting value, and the level that new setting value comprises to adjust panel 1 display simulation video signal input signal is counted, phase place and position.And, the new setting value produced after the resolution that this analog video input signal is also selected by processor 2 and automatic calibration is stored in this memory body 3, when this display screen 100 again receives this analog video input signal and carries out the flow process as Fig. 2, this processor 2 can read and apply mechanically the setting value stored in this memory body 3 and show this analog video input signal, the namely content of step S03, step S04 and step S14 to control this panel 1.Finally, then carry out step S26 after completing steps S25, processor 2 is applied mechanically this new setting value and is shown this analog video input signal to control this panel 1.Whereby, when user is when the resolution of the process step setting mistake of Fig. 2, user can reset resolution by the process step of Fig. 5 and carry out automatic calibration.
In sum, the preferred embodiment of display screen 100 of the present invention is when display screen 100 receives analog video input signal, and when receiving correction instruction, initiatively can show OSD menu picture to select to confirm correct resolution for user, the situation of fuzzy pictures is produced because erroneous judgement resolution, so really object of the present invention can be reached to avoid display screen 100.
