The lock state of screen of step S4, maintenance terminal 1.

In step S1, the S2 and S4 of said method, display unit 13 is controlled screen in the screen state that goes out, and screen background lamp is not opened.

In the present embodiment, before step S1, terminal 1 is in lock state of screen, and this state is the released state for the treatment of that can receive user and input release information, does not need user to input startup screen unlock command.In other embodiment, before step S1, also there is a step S0: input block 14 obtains startup screen unlock command; Described startup screen unlock command is identified and analyzed to judging unit 16, and judge whether unlocking screen instruction and default startup screen unlocking condition coincide, in the time judging that startup screen unlock command and default startup screen unlocking condition are identical, respond described startup screen unlock command by processing unit 11, call display driver unit 12 and show and treat released state on screen in order to control display unit 13.Describedly treat that released state can be the state of screen display normal brightness, or show lower than the state of normal brightness or the position display of certain on screen one presupposed information only, in order to inform user now terminal 1 in treating released state, user can utilize input block 14 to input release information at this moment, described presupposed information can for system default treat that released state information is as " asking release ", can be also user-defined release information; Described presupposed information can be set by the user and in screen optional position.In present embodiment, described normal brightness refers to the brightness setting when electronic equipment normally uses.

Release information described in this method can be any operation information from user that input block 14 that terminal 1 possesses can obtain.For example:

In the time that input block 14 is button, release information can be the key combination characteristic items such as number of times, frequency or number of times and the frequency of button.If unlocking condition is " button within 2 second time by by 3 times ", user's button 3 times within 2 second time, judging unit 16 judge release information and unlocking condition identical.

In the time that input block 14 is physical keyboard, release information can be key combination characteristic item.If unlocking condition is " U, N on keyboard, L, O, C, K key are pressed successively ", user uses physical keyboard input UNLOCK, and judging unit 16 judges that release information and unlocking condition coincide.

In the time that input block 14 is touch-screen, release information can be touch-control affair character item, and described touch-control affair character item is the assemblage characteristic item of contact, contact combination, sliding trace, sliding trace combination or contact and the sliding trace of input media on touch-screen.For example, when unlocking condition is for " information of shape that touch-screen receives identical ' W ' ", user uses finger, capacitance pen or other input medias on touch-screen, to draw ' W ' shape, and judging unit 16 judges that release information and unlocking condition coincide.And for example unlocking condition is the figure that certain contact and sliding trace combine, judging unit 16 is in the time receiving the release information that input block 14 obtains, calculate its eigenwert, compare with the eigenwert of this figure in unlocking condition, in the time that error is less than a predetermined threshold value, be judged to be release information and unlocking condition and coincide.

With existing touch-screen track release scheme, the common nine grids track release of for example Android system smart mobile phone is compared, the release scheme of the present embodiment is more flexible, confidentiality is stronger, for example, in nine grids release scheme, as a in Fig. 3 is depicted as nine grids release interface, unlocking screen figure is zigzag, track is successively through being numbered 1 → 2 → 3 → 5 → 7 → 8 → 9 tracing point, therefore trajectory shape, position, size is relatively changeless, in the present embodiment, the shape correlation that the eigenwert that for example we set is track, as long as the zigzag that is shaped as of track therefore detected, no matter the size of zigzag track, position, for example input b in Fig. 3, the track of release shown in c all can be realized release.

In further improved embodiment, whether input block 14 comprises gravity sensor, have at touch screen and longitudinally place the characteristic that all can receive release information when laterally placing when contact panel receives touch information when user can be according to oneself requirements set release.If it is to input release information just effectively on contact panel that user is set to longitudinally to place at mobile phone, in the time of unlocking operation, user sends startup screen unlock command by the physical button in input block 14 or other triggering forms, processing unit 11 starts contact panel and gravity sensor, and contact panel and gravity sensor are initially located in and can receive external information state.Now user need to longitudinally place and input on contact panel release information by mobile phone, judging unit 16 is according to judging that from the information of gravity sensor mobile phone is now in longitudinal laying state, and the touch-control affair character item that judging unit 16 receives contact panel judges after identifying, analyze and comparing that release information and unlocking condition coincide, after having met these two conditions, processing unit 11 is removed the lock state of screen of mobile phone.

On the other hand, when user can arrange mobile phone in longitudinal placement and laterally place, input release information all effective.In the traditional unlocking manner shown in Fig. 3 a, tube apparatus is not laterally or vertically to place, its track all needs to pass through as shown in Figure 3 a above-mentioned path point, but in the time that equipment is laterally placed, its release path also needs horizontal, and in the time laterally placing, actual input path becomes " N " font by " Z " font.In the present embodiment, in the time that gravity sensor detects that equipment is horizontal, the track detecting is also done to lateral processes, for example, in inputting Fig. 3 in the time that mobile phone is laterally the placed track shown in d and e, judging unit 16 will do lateral processes to the detected track of contact panel, and being judged as what receive is zigzag.Like this, no matter equipment laterally or is vertically placed, all can use identical user habit release.

In the time that input block 14 is camera, release information can be user's image information feature item that camera can collect carry out an operation before camera time, while being " camera receives a finger from left to right or motion from right to left " as unlocking condition, user stretches out finger transverse movement before camera, judging unit 16 is by identification and analyze the received image information of input block 14, calculate its eigenwert, compare with the eigenwert of this motion image in unlocking condition, in the time that error is less than a predetermined threshold value, be judged to be release information and unlocking condition and coincide.Wherein, can be by user in advance with the condition set, use the action inputted of input block 14 be set as unlocking condition,, in the time that user need to carry out release in the future, carry out unlocking operation with same action.In the time that input block 14 is image scanning apparatus in like manner, difference is that release information that camera can obtain is still image information characteristics item or the dynamic image data characteristic item that is made up of continuously still image, can only be still image information characteristics item and image scanning apparatus obtains.

When input block 14 is pot, sound receiving equipment, fingerprint identification device, or when the sensor device such as light sensor, acceleration transducer, release information can be the user action information characteristic item that current potential information characteristics item, voice recognition information characteristics item, finger print information characteristic item, sensor capture, user uses input block 14 to input release information, judging unit calculates the eigenwert of release information, compare with the eigenwert of unlocking condition, in the time that error is less than a predetermined threshold value, be judged to be release information and unlocking condition and coincide.

The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes instructions of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
