The principle of the application and feature are described in further detail with reference to the accompanying drawings and examples.It is understood that It is that specific embodiment described herein is used only for explaining related invention, rather than the restriction to the invention.It further needs exist for It is bright, part relevant to invention is illustrated only for ease of description, in attached drawing.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The application uses a kind of driving method of improved touch-control display panel, shortens the sweep time of touch control electrode. As shown in Figure 1A, it illustrates the flow charts according to one embodiment of the driving method of the touch-control display panel of the application 1000.As shown, the driving method of above-mentioned touch-control display panel may include steps of:
Step 1001, driving chip is divided into first to m1 the first touch control electrode group for first to n-th touch control electrode The scanning of first time touch-control is carried out, and each touch control electrode in each first touch control electrode group receives the touching of driving chip transmission simultaneously Control scanning signal.
In the present embodiment, above-mentioned touch-control display panel may include N number of touch control electrode 101 and at least one driving chip 103, which can provide touch scanning signals for above-mentioned each touch control electrode 101, and as shown in Figure 1B, Figure 1B is shown Using a distribution of electrodes schematic diagram of the touch-control display panel that the driving method in Figure 1A is driven.It should be noted that In the touch-control display panel, above-mentioned each touch control electrode 101 can be arranged along first direction, be followed successively by the first touch control electrode, Two touch control electrode ... N touch control electrodes, as shown in Figure 1B, N here can be positive integer.
In the present embodiment, above-mentioned driving chip 103 can be divided into first to for first to n-th touch control electrode 101 M1 the first touch control electrode groups carry out the scanning of first time touch-control, and m1 here is positive integer.In above-mentioned each first touch control electrode group May include equal number of touch control electrode, also may include different number of touch control electrode, and above-mentioned each touch control electrode It must be positioned in one of them first touch control electrode group.It should be noted that being included in above-mentioned each first touch control electrode group Touch control electrode 101 be all different, for example, this first if the first touch control electrode is in first the first touch control electrode group Touch control electrode cannot be in second to m1 the first touch control electrode group, and this can enable each touch-control electricity on touch-control display panel Pole 101 is scanned during first time touch-control scans and is only scanned primary.Therefore, if occurring on touch-control display panel Touch operation, in the first time touch-control end of scan, driving chip 103 can be determined where the touch control electrode that touch operation occurs The first touch control electrode group.
As shown in Figure 1B, if above-mentioned touch-control display panel is equipped with 16 touch control electrodes 101, respectively the first touch-control electricity Pole, the 16th touch control electrode of second touch control electrode ..., i.e. N=16.Above-mentioned driving chip 103 can be by first to the 16th touch-control Electrode is divided into 4 the first touch control electrode groups, i.e. m1=4, respectively first the first touch control electrode group 110, second first touching Electrode group 120, third the first touch control electrode group 130 and the 4th the first touch control electrode group 140 are controlled, it as shown in Figure 1B, should Driving chip 103 carries out the scanning of first time touch-control to first to the 4th the first touch control electrode group.It should be noted that first During secondary touch-control scanning, each touch control electrode in same first touch control electrode group can receive above-mentioned driving core simultaneously The touch scanning signals that piece is sent.For example, may include on touch-control display panel in first the first touch control electrode group 110 One to the 4th touch control electrode 101, as shown in Figure 1B, then first time touch-control scan during first to the 4th touch control electrode 101 can receive the touch scanning signals of the transmission of driving chip 103 simultaneously, and driving chip 103 is allowed to scan first simultaneously To the 4th touch control electrode.Similarly, second the first touch control electrode that above-mentioned driving chip 103 can simultaneously in scanning figure 1B Each touch control electrode in group 120, while each touch control electrode of the first touch control electrode group 130 of third is scanned, and scan simultaneously Each touch control electrode in 4th the first touch control electrode group 140.As it can be seen that driving chip 103 is by touch control electrode in the present embodiment 101, which are divided into m1 the first touch control electrode groups, carries out the scanning of first time touch-control, and driving chip 103 can be successively to each first touch-control Electrode group sends touch scanning signals, and driving chip 103 is allowed to export m1 touch scanning signals to touch-control display panel The first time touch-control scanning to the touch-control display panel can be completed.
It may include quantity phase in above-mentioned each first touch control electrode group in some optional implementations of the present embodiment Same touch control electrode 101, the number N of the touch control electrode 101 on touch-control display panel is the number of the first touch control electrode group at this time The integral multiple of m1.For example, may include 16 touch control electrodes in touch-control display panel, each touch control electrode 101 can as shown in Figure 1B To be divided into first the first touch control electrode group, 110, second the first touch control electrode groups 120, third the first touch control electrode group 130, the 4th the first touch control electrode group 140, and include 4 touch control electrodes, i.e. N=16, m1 in each first touch control electrode group =4.It is appreciated that the number N for the touch control electrode for including in above-mentioned touch-control display panel according to the needs of actual conditions can not Together, and the number m1 of above-mentioned first touch control electrode group can also be different, for example, above-mentioned N and m1 can also be respectively 20 and 5, this When each first touch control electrode group in include 4 touch control electrodes or above-mentioned N and m1 can also be respectively 30 and 6, each at this time the Include 5 touch control electrodes in one touch control electrode group, does not limit uniquely here.
Step 1002, driving chip is divided into first to the m2 second touch control electrode group for first to n-th touch control electrode Second of touch-control scanning is carried out, and each touch control electrode in each second touch control electrode group receives the touching of driving chip transmission simultaneously Control scanning signal.
