Detailed description of the invention
Referring to Fig. 1, it is the flow chart of the power-economizing method according to the display with ASD function depicted in one embodiment of the invention.First to illustrate that, manufacturer is when display dispatches from the factory, by ASD functional condition for closing, before display is not the most started shooting after dispatching from the factory, even if being under standy operation mode because connecting alternating current power supply, will be closed without whether all signal sources of opening section circuit detecting have signal to input because of ASD function, therefore display power consumption under standy operation mode can be allowed relatively low, such as less than 0.5W.
Secondly, manufacturer, before display dispatches from the factory, can call the NVM(for storing the often data of variation such as various setting values initialized in display in the following text data NVM) in stored ASD setting value be set as the unknown；Or, directly data NVM that content is empty can be configured in display, the most maybe can by script content content for empty data NVM empty, during so that display is started shooting after dispatching from the factory for the first time, display from for stocking system and application program and various wait the NVM(with little or no the data that can change to call program NVM in the following text such as mark) reading also loading system program, it can first judge when performing that whether the content of data NVM is empty, the most then can start initialization data NVM and automatically ASD setting value is set as the unknown.No matter making ASD setting value stored in data NVM be unknown by which kind of mode above-mentioned, its purpose is all when display to be allowed is started shooting after dispatching from the factory for the first time, can be because determining ASD setting value to automatically turn on ASD screen menu for the unknown, it is turned on and off ASD function to provide user to set, and after user sets, close ASD screen menu just enter normal mode of operation, and only perform the recovery genuine set-up function provided in main screen menu, otherwise will no longer be shown this ASD screen menu.
If user opens ASD function, under then display is in standy operation mode, the circuit for detecting of all signal sources can be opened to detect whether all signal sources have signal to input, so that when detecting either signal source and having signal to input, automatically into normal mode of operation and be switched to the signal source of signal input with picture corresponding to display, need not user manual turning-on signal source screen menu manually select again to be switched to certain signal source from signal source screen menu, so can increase the convenience in use, but the power consumption under standy operation mode can be caused higher, such as higher than 0.5W.
If user closes ASD function, under then display is in standy operation mode, only can open the circuit for detecting of the signal source of last use, whether the signal source that only the detecting last time uses has signal to input, can't go to detect whether other signal source has signal to input, therefore display power consumption under standy operation mode can be allowed relatively low, such as less than 0.5W.Have signal to input if detecting this signal source, then display can enter the normal mode of operation picture with display correspondence.If detecting the input of this signal source no signal, then display may proceed to stay in standy operation mode, without detecting whether other signal source has signal to input, now user is if it is known that other signal source has signal to input, then user can only manual turning-on signal source screen menu manually select again to be switched to from signal source screen menu known to have signal to input signal source, display just can be made according to picture corresponding to selected signal source display.
As it is shown in figure 1, in the present embodiment, in step S11, when display starting, whether display, from program NVM loading system program, can the first content judging data NVM in step S12 be empty when it performs.If step S12 judge the content of data NVM as empty, then ASD setting value in step S13 initialization data NVM and is set as the unknown by program automatically.If step S12 judges that the content of data NVM not as empty, then reads stored ASD setting value in step S14 from data NVM.At this it is to be appreciated that after display dispatches from the factory during start for the first time, the ASD setting value read can be the unknown set before dispatching from the factory by manufacturer, and when starting shooting afterwards, the ASD setting value read will be by being turned on and off set by user.Then, after step 13 or step 14, program enter step S15, display can from program NVM read stored by mark and show, then in step S16, timing stops after a scheduled time display identify.
Subsequently in step S17, display can judge whether ASD setting value stored in data NVM is unknown.If step S17 judges that ASD setting value is as unknown, then represent that display is start for the first time, therefore automatically turn on ASD screen menu in step S18, it is turned on and off ASD function to provide user to set, and after user sets in ASD screen menu, perform step S19 and setting result is stored into ASD setting value and closes ASD screen menu.
In one embodiment, as shown in Figure 2, ASD screen menu 1 display is turned on and off the option one 1 and 12 of ASD function, the option of suggestion it is labeled as at option one 1 rear opened, being labeled as the option preset at option one 2 rear closed, and cursor 13 rests on the option of closedown, this outer lower side may also display the information of countdowning, if with prompting user countdown end after the most unconfirmed, will automatically perform the option of cursor dwell.User can press up/down/left/right key and move the cursor 13 in ASD screen menu 1 or change cursor 13 position by command input devices such as remote controllers, and pressing acknowledgement key carries out confirming to set when cursor 13 rests on the option wanted.
nullAs shown in Figure 1，Program is in step S191，Judge whether user presses up/down/left/right key，If user has pressed up/down/left/right key really，Program cursor 13 in step S192 determines mobile ASD screen menu 1 or change the position of cursor 13，In step S193，Program judges whether user presses acknowledgement key，If，User presses acknowledgement key，Then represent that user confirms the option (being turned on and off) of 13 stop places of cursor to be set as ASD setting value，Therefore in step S194，User is set result and stores into ASD setting value and close ASD screen menu 1 by program，Now ASD setting value is turned on and off becoming according to the setting of user and is no longer the unknown，And display will be that unlatching is opened and performs ASD function according to ASD setting value，Or do not perform ASD function according to ASD setting value for closing，Program enters the normal mode of operation of step S20.
After display is for the first time started shooting and entered normal mode of operation, ASD setting value will can be only by being turned on and off two kinds of values set by user.Under display is in the normal mode of operation of step S20, user can make display shut down by the power key on the command input devices such as pressing remote controller and enter standy operation mode, and display starting can be made by pressing power key again under standy operation mode, perform step S11, now because judging that the content of data NVM does not performs step S14 as sky in step s 12, wherein stored ASD setting value is read from data NVM, in step S15 display mark, after a scheduled time, display mark is stopped in step S16, afterwards in step S17, i.e. can be because judging that ASD setting value is not unknown and be directly entered the normal mode of operation of step S20, that is ASD screen menu 1 will not occur again.
To ASD screen menu 1 occurs again, then user must be under display be in the normal mode of operation of step S20, in step S21 by the button manually opened main screen menu on the command input devices such as pressing remote controller, and in step S22, from main screen menu provide such as various functions such as brightness settings function, contrast settings functions choose recovery genuine set-up function and confirm to perform.In step S23, when display receives the order that user genuine to be recovered sets, display recovers genuine set-up function by performing and various setting values stored in data NVM is returned to genuine setting value, it is set as the unknown including by ASD setting value, and after performing to recover genuine set-up function, close main screen menu, now become unknown due to ASD setting value, therefore step S18 is returned, display can automatically turn on ASD screen menu 1, it is turned on and off ASD function to provide user to set, and after step S19 user sets in ASD screen menu, setting result is stored into ASD setting value and closes ASD screen menu.
Although the present invention is disclosed above with preferred embodiment; so it is not limited to the present invention, any is familiar with this those skilled in the art, without departing from the spirit and scope of the invention; when making a little change and retouching, therefore the protection domain of the present invention is when being as the criterion depending on as defined in claim.
