Display panel 200 is showing a picture, e.g. a liquid crystal display panel or an organic light-emitting diode display
Panel.
Contact panel 100 is arranged on display panel 200, and user can be directly in the picture shown by display panel 200
Millet cake is selected or marked, there is provided the intuitive hommization operation interface of user.
Pursued in electronic installation under compact trend, the sweep circuit block of contact panel 100 and display panel 200
Shared design, the design to overlap or the neighbouring design set may be adopted.By the scan method of the present embodiment, whether adopt
With shared design, the design to overlap or the neighbouring design set, the driving of contact panel 100 and display panel 200 will not phase
Mutually it is interfered, and the operating characteristics of contact panel 100 and display panel 200 can be maintained.
Fig. 2 is refer to, it illustrates first line block T1~T12 and second circuit block L1~L12 scanning sequency is shown
It is intended to.Contact panel 100 has several first line block T1~T12, and display panel 200 has several second circuit block L1
~L12, each first line block T1~T12 can disturb corresponding each second circuit block L1~L12.For example,
One circuit block T1 can disturb the second circuit block L1, first line block T2 to disturb the second circuit block L2, and the rest may be inferred.

Meter, the design to overlap or the neighbouring design set.Fig. 3 is refer to, it illustrates Fig. 2 first line block T1~T12 and second
Circuit block L1~L12 with time slot TS1~TS12 operation corresponding diagram.In the case of using shared design, first line area
Block T1~T12 and second circuit block L1~L12 difference share wires blocks B1~B12.At any point in time, circuit block B1
~B12 it is therein it is any will not simultaneously be used by contact panel 100 or display panel 200.
In one embodiment, the first scan frequency of contact panel 100 can be equal to the second scanning frequency of display panel 200
Rate, contact panel 100 can sequentially scan first line block T1~T12, display panel 200 since first line block T1
The second circuit block L2~L12 and L1 can be sequentially scanned since the second circuit block L2.Thus, you can avoid circuit
Block B1~B12 therein any while used by contact panel 100 or display panel 200.
In one embodiment, the first scan frequency of contact panel 100 can be not equal to the second scanning of display panel 200
Frequency.It is the mode of operation for describing this scan method in detail by Figure 1B flow chart below.
In step S101, the first scan frequency of contact panel 100 is calculated relative to the second scanning of display panel 200
One frequency ratio of frequency.First scan frequency is not equal to the second scan frequency.For example, Fig. 2 is refer to, frequency ratio is 2 times
When, the period of time T F twice of a time cycle LF of display panel 200 equivalent to contact panel 100.In general, touch-control
Panel 100 needs the first higher scan frequency, to maintain the efficiency of touch-control susceptibility.
In step s 102, according to frequency than distinguish first line block T1~T12 correspond to several time slot TS1~
TS12, and distinguish second circuit block L1~L12 and correspond to several time slot TS1~TS12.In this step, if frequency ratio is
N1/N2, N1/N2 are fraction in lowest term, then each time slot TS1~TS12 corresponds to N1 first line block T1~T12, Ge Geshi
Gap TS1~TS12 corresponds to N2 second circuit block L1~L12.By taking Fig. 2 as an example, frequency ratio is 2/1, then each time slot TS1
~TS12 corresponds to 2 first line block T1~T12, each time slot TS1~TS12 correspond to 1 the second circuit block L1~
L12。
The scan method that the present embodiment is provided is applied to N2 and is equal to the situation of 1 (i.e. frequency ratio is integer), N2 for more than 1
The situation of integer (i.e. frequency ratio is non-integer), N1 is more than N2 (i.e. the first scan frequency of contact panel 100 is more than display surface
Second scan frequency of plate 200) situation or N1 be less than N2 (i.e. the first scan frequency of contact panel 100 is less than display panel
200 the second scan frequency) situation.In the embodiment of fig. 2, it is to be equal in case of 1 and N1 is equal to 2 to say by N2
It is bright.Remaining various situation is described in other embodiments respectively.
In this step, the circuit block B1 that the time slot TS1~TS12 planned quantity is substantially equal to shared~
B12 quantity.Also, each time slot TS1~TS12 sweep time is substantially equal.
