100。
For manipulating track F, manipulation track F is that second sensing area 204 of the optical signal SL in display panel 200 moves up
It is dynamic and form a not closed area, that is, optical signal SL passes through multiple display units 100 of the second sensing area 204, and without
Duplicate display unit 100 and form not closed area.In under this condition, in response to manipulating track F, in the second sensing area 204
Multiple display units 100 sequentially generate corresponding multiple sensing signal VS2 to controller 220.If controller 220 receives
The sensing signal VS2 that two sensing areas 204 generate, and no longer receive the sensing signal VS2 of the generation of repetition display unit 100, i.e.,
It can recognize the motion track of manipulation track F.As shown in Figure 2 A, manipulate track F motion track be by the second sensing area 204,
It is no longer pass through duplicate display unit 100.
By taking above-mentioned manipulation track D~F as an example, in some embodiments, controller 220 can be according at least one sensing signal
VS2 determines direction of rotation of the manipulation track D~F on the imagery zone of display panel 200 and whether to form a closing
Region.In this way, according to different rotary direction and whether to form closed area, controller 220 can be from multiple preset instructions
Selecting one is the manipulation instruction to be executed, and display panel 200 is driven to show the manipulation instruction.
Above-mentioned manipulation track A~F merely illustrative purposes, what various manipulation tracks were all considered in present disclosure content
In range.
In some embodiments, controller 220 is more to output drive signal VC, with drive display panel 200 in response to
The manipulation track that controller 220 is identified shows corresponding manipulation instruction.As it was earlier mentioned, in one or more embodiments,
Controller 220 can be according to an at least sensing signal VS1 and/or at least sensing signal VS2 identification optical signal SL in display panel
The manipulation track generated on 200.According to this manipulation track touch the edge of display panel 200 and the sequence of imagery zone, whether there is or not
One or more conditions such as closed area and/or direction of rotation are formed, the exportable corresponding driving signal VC of controller 220 is to drive
Display panel 200 shows corresponding operation.Therefore, controller 220 exports corresponding driving signal VC extremely according to above-mentioned judgement
Display panel 200 makes display panel 200 show corresponding operation.
For example, in some embodiments, behaviour that controller 220 generates on display panel 200 to identify optical signal SL
Track is controlled, first judges whether that whether there is or not touch the first sensing area 202 for manipulation track；If without the first sensing area 202 is touched, then judging to grasp
Whether control track forms a closed area；If to form closed area, then judge the direction of rotation of the manipulation track；Alternatively,
And if touch the first sensing area 202, then judgement be first touch the first sensing area 202 or first touch the second sensing area 204, then
Judge finally to touch is the first sensing area 202 or the second sensing area 204.It above are only example, the disclosure is simultaneously not only stated above
Judgement sequence is limited.
For ease of understanding, it is manipulation instruction 1, manipulation that A corresponding Operation Definition in track will be manipulated in present disclosure
B corresponding Operation Definition in track is manipulation instruction 2, and the corresponding Operation Definition of manipulation track C is manipulation instruction 3, manipulates D pairs of track
The Operation Definition answered is manipulation instruction 4, and the corresponding Operation Definition of manipulation track E is manipulation instruction 5, corresponding with manipulation track F
Operation Definition is manipulation instruction 6.In some embodiments, display panel 200 is corresponded to according to the driving signal VC display received
Manipulation instruction 1~6.
With reference to Fig. 3.Fig. 3 is the schematic diagram of the optical signal SL according to shown by some embodiments of present disclosure.Yu Yi
In a little embodiments, the light emitting source of control device 240 can export different optical signal SL under a variety of different modes.Optical signal SL's
There to be different set-up modes according to different mode (during being for example, in high level) during enabled.For example, as shown in figure 3,
Control device 240 can be generated at continuous wave (continous wave) mode CW or surging (pulse) mode P to be made with difference
Optical signal SL during energy (during enable).
In Fig. 3, the optical signal SL1 that control device 240 is sent out under continuous mode CW has an enable time TCW.

In Fig. 3, the optical signal SL2 that control device 240 is sent out under surging mode P has a cycle T P.Some
In embodiment, the cycle T P of surging mode P is less than 16.6ms.In other words, in surging mode P, every two phase in optical signal SL
The time difference of adjacent enabled period TH will be less than 16.6ms.As shown in figure 3, the cycle T P of the optical signal SL2 under surging mode P
Less than 16.6ms, therefore its enable time TH is also smaller than 16.6ms.In other words, the repetitive rate of the optical signal of surging mode P is greater than
60Hz。
In some embodiments, multiple aobvious in display panel 200 as the enabled period of optical signal SL1 or SL2 are different
Show that unit 100 can produce sensing signal VS1 or VS2 with different timing.In some embodiments, controller 220 more to
Distinguish the enabled period of optical signal SL, according at least timing of sensing signal a VS1 and/or VS2 to confirm control device 240
Operation mode.In some embodiments, the difference according to the enabled period of optical signal SL, the also exportable correspondence of controller 220
Driving signal VC, so that display panel 200 be made to show different manipulation instructions.
Accordingly, according in one or more above-mentioned embodiments, in addition to touched according to manipulation track the edge of display panel 200 with
The sequence of imagery zone, whether there is or not formed one or more conditions such as closed area and/or direction of rotation, controller 220 can also basis
The difference of the enabled period of optical signal SL further is classified to preset instruction set, therefrom to select corresponding operation.
In some embodiments, according to Fig. 2A and Fig. 3, the identification of controller 220 manipulates track A~F and identifies optical signal
Mode CW or P, make above-mentioned each manipulation instruction 1~6 that can be divided into two manipulation instructions.Also that is, the rail of collocation identification
